I've owned my pool for 20 years and this is the first and only time I've gotten a really good idea of how to backwash properly. THANK YOU THANK YOU! I wish I'd known this long ago. I like the cutaway of the filter so I can actually SEE what is happening when I do it.
I’m new to this but couldn’t have a better teacher. I’ve learned so much. Thank you
Mark's videos are very beneficial; my pool is over the top since I followed Mark's instructions. I had a pool specialist coming three times a year, costing me over 1000 Euros. I had no knowledge of pool maintenance since I moved to France. Now I do it myself. Thank you very much.
Mark, as I understood, you must backwash first and add chemicals after 24 hours. Am I correct?
Thank you Mark. I fully understood every word you said. You have made me a professional pool cleaner of my above ground pool. God bless you now I can save $200.00 for cleaning
Great Video. I've had a pool for 35 years and I can tell you that this is the best explanation of how to run your filter that I've ever seen. I found it because I need to have a friend take care of my pool when I'm gone so we watched it together. GREAT JOB!!
Great video. This information is going to make my summer!
I’ve owned the pool for 9 years and I didn’t know how the filter worked. Amazing.
Great video
Absolutely the best pool information. I have learned so much to maintain my in ground pool. Thank you very much.
Thank you again Mark for another great lesson on taking care of our pool.
This was a great video but I just needed a little extra info regarding the sight glass per my question below🙂
You have the best informational videos. Thank you so much for doing all these!
Thanks for showing this and the inside view of the pump. Short and simple.
You seriously rock! Love your descriptions.
Appreciate all the needed info
Thanks Mark
Loving your videos. Thanks a bunch
Very helpful, thank you. I had no idea how this filter worked after buying it, this video made it very clear
That was very helpful. Thank you, Mark!
Best video I see so far thanks a lot 😀
Great Explanation...Thanks for sharing...
great easy to understand video. Thank you.
This is not what I'm looking for but I think this video it's very helpful
Awesome vids!!!
Hi, I've just found your channel very very good thank you for your help. I've just moved to Spain and taken over the upkeep of our pool, so will be binge watching your videos. if i were in the same country as you I would definitely use your shop. once again thanks 👍👍
Thanks for the easy to follow explanations and videos. As a new pool owner (the home we bought had an existing in ground) it’s easy to get confused by jargon or conflicting advice. You’ve just earned a new subscriber. I’ll have to check your other videos to see if there’s one that shows how to install a new pressure gauge because mine is so cloudy it’s hard to see the needle.

@@HallmarkPoolSupplies Thank you! I’m starting down the rabbit hole watching all of your videos so I can learn more about my pool and how to properly maintain it.
Awesome tutorial!!!! Thank you!!!!
Thanks it was very helpful,
EXCELLENT VIDEO!!!!!
La mejor explicación para los que somos nuevos en cómo tratar una alberca 👍
Great vid Mark---Astoria Loves ya.
thank you for your video
Thanks that was perfect
Wow...I've made these transitions without ever turning off pump
Nice video
Thank You
Best pool video out there. My pool pump didn't run for 3 days, got a new pump. and of course it turned cloudy greenish with algae floating around. Added small amounts of algacide and shocked it. Should I backwash more frequently until clear? Thanks
Perfect!!
Thanks
good video
Thenk you.
I'm backwashing when the psi hits between 17-19. Then a rinse for 30 seconds right after.
After the above my Hayward runs at 12 psi.
Thx
I have the same kind of pool pump like you had in the video
Thank you very much for the easy explanation regarding how filter works actually and the backwash, I have a pool when I vacuuming the pool in few minutes the pressure disappear than I have to change the position in the filter valve to backwash for few seconds than to filter again for to continue to vacuuming is there any special reason Sir?
If the pool is very dirty and you have a lot of algae and debris you vacuuming, then this could be a reason why you have to backwash in between vacuuming.
Thanks for your lesson. Which valves should I open when I want to backwash
If you are referring to the drain or skimmer valves, it does not matter which is open as long as the pump is getting water. Thanks for watching.
Mark I have been in the pool industry for over 35 years. I sell those Hayward filters and they have sight glass. When you
are back washing you look @ the sight glass till it runs clear. Then, when you are rinsing you do the same till it runs clear.
So timing it is irrelevant.
I like to do both, in this video l do have a link to another video called basic filter operation where l go into more detail about the sight glass and overall operation of the system. Thanks for watching.
great video !! do you need to backwash if you have a filter catridge system ? or just take the catridge out and hose it down ?
Cartridge filter systems must be manually cleaned. Thanks for watching.
Very well explained!
Hello great videos, do you have any experience with filter balls versus sand in a sand filter we’re trying filter balls and we’re wondering if the back washing method is the same with filter balls thank you
Backwashing and rinsing will be the same, however I prefer sand because it is much finer and will filter the water better.
Thank you for your helpful videos. My question is when do I know if I need to add or change the sand in my filter? I have in-ground saltwater pool.
You do not have to add sand but you should change sand about every 3 to 5 years. Thanks for watching.
Hi Mark I nowI have to do my own pool cleaning and I’m trying to get the hang of how to do a backwash on my Hayward DE filter I’m not sure if other than turning on the skimmer is there anything else I’m supposed to have open such as jets and island when running the backwash process?
Everything is the same as you are running on filter, nothing is different when you backwash.
Hello Mark! Great video! So I did not know and yesterday I put in a treatment , because my pool got green , how long should I wait before I backwash? Should I do it after I vacuum the pool ? Thank you!
I would wait 24 hrs before you backwash, after you vacuum the pool you can backwash as well. Thanks for watching.
Do some water goes through waste when we backwashing or just in case of rinse? Great channel thanks a lot!
When you backwash, rinse or use waste all the water exits through the same pipe. Thanks for watching.
Evening Mark, I have a leak coming from the top of my sand filter and under my top mounted multi port valve, I have replaced the o ring and tightened the clamp, when the filter is on filtration, backwash or rinse the multi port valve rises and leaks but when on recirculate it’s fine??? It seems to me is building up with pressure and causes the multi port to pop up, if that makes sense. The sand in the filter was replaced in April with 75kg of sand 🤔
I would recommend to remove the valve and check the o ring again. Make sure it did not move out of place and it is clean (no debris or sand). Also make sure the proper type of sand was used #20 silica.
Hi Mark,
Can u explain me the positions of the tubes during the processes. So when we backwash we open the tube to waste, skimmer, drain. And close the hoover and the backwards to pool?
I have a video called basic filter operation that goes into great detail on how to operate the filter system and how to use all the positions. If you watch this it should help. Thanks for watching.
My backwash is on/off, norinse or anything else. How does this help me!
Due to heavy rains water way over skimmers do I backwash or other setting
If you need to backwash and rinse anyway that would be fine. Normally to lower the water fast, you would use waste. Thanks for watching.
This was posted quite some time ago, but I’m also extremely curious when you backwashed does your pressure get higher when your backwashing I’m new to sand filters and I don’t quite fully understand quite yet When I backwash I noticed the tank seems to swell up and I go to about 13 psi when it’s backwashing it starts off at about eight psi and then all the sudden jumps up to about 13,14 psi
You want to backwash your filter when the pressure gets about 8 to 10 psi above your start pressure. When you backwash the gauge can fluctuate, when you are done backwashing the pressure in the tank will come down and the pressure on the jets in the pool will increase. I do have a video on basic filter operation for use with a sand filter, here is the link and hopefully this will help. Thanks for watching.

Great explanation how the whole thing works. Never did now I do. Thanks😀👍
after making a backwash in a pool do we have to put another chemical on the skimer like a powder?
As a rule of thumb backwash, rinse and then you would add chemicals. Never add chemicals and than backwash in the same 24 hrs. If you are referring to a DE filter than you would add DE as needed.
Do I need to change the filters and how often you change it
What type of filter do you have?
We just got a new pool with a sand filter and didn’t know that you have to backwash. We got some debris in the pool when we first turned it on because we went straight to the filter setting. Is it still safe to swim in?
Yes, thanks for watching.
Should I turn off the drain valve while backwashing ? Or should I release the drain valve after completing the rinse process?
When backwashing or rinsing typically both drain and skimmer lines are left open.
So from my understanding turn pump off everytime u mibe handle turn back on move the handle turn on an turn off every time you move handle an backwash an rinse?
Yes, thanks for watching.
I have 2 sides of the pool 1 baby 2 feet deep while other part double of this small side looks crystal water and other side is dark made me think that the tiles are gone to colour change. Could this be ever happened ?if a problem of water how i can see beautiful water in the small one?
Color of the surface along with the water depth will change the appearance especially if water is clear or hazy. Thanks for watching.
should i turn the valve drain and return on during backwash?
It makes no difference if your pump pulls water from the skimmer or the drain, as long as the pump is primed when backwashing.
Fullpack to support idol,,but i need to watch from the start idol,, from the valve and the switch to ON and OFF, because some other have,filter pump and fountain pump,i confused where is the switch i ON after turning backwash, filter pump switch o fountain pump switch,need more your video idol,thank you
can you replace a gage? my filter has a broken gage.
@@leilam.murango3485 Yes, if you need a gauge l carry them. Email your contact info and l can help, my email is on my CZcams channel. Thanks for watching.
Let’s say when you pour in the sand for the first time and might have not by any chance be leveled in the tank. Does the sand level itself in the tank when you start operating it?backwashing, rinsing it and all that?
You want to put the correct amount of sand in your tank. The label on your tank will tell you how much you need. If you put a little to much in, the tank will self level. Do not fill the tank all the way up. If you have any questions feel free to contact me.
Do you backwash with pump on high or low?
Always backwash the filter using a higher speed so you have enough power to clean the filter. Thanks for watching.
What is the purpose of the sight glass on the filter and what should it look like when it is running? All I see is about 2mms of stagnant water sitting at the bottom of it and the filter makes a slights sloshing sound. Is this normal?
When in the filter position the sight glass is clear and empty. When backwashing and rinsing the filter the sight glass will show the condition of the water as it leaves the filter. If you have a little water at the bottom of the glass when you are done, this will be fine. Thanks for watching.
After rinsing and putting back to filter does water still come out the backwash hose some
When in filter water should not come out of the back wash line. Make sure that the valve is seated in place. If water does not stop coming out of the back wash line you may have to check the gasket inside the valve.
@@HallmarkPoolSupplies thank you . The handle broke so I bought a new top assembly. Maybe that will help.
I backwashed after adding chemicals, and now my water looks a bit cloudy - chauky. What can I do to make the water look clear? Thank for your help.
@@pita-bw2cy I recommend having your pool water tested at your local pool store. Then you will know what to add to balance and clear the pool. Thanks for watching.
What to do if return jets are weak and gauge on filter is showing lower than normal psi?
Thanks for informative videos!
You may need to backwash the filter, if you already back washed and pressure is still weak you may need to change sand in your tank. If you put your system on recirculate and the pressure is still weak then you will need to check your pump's impeller. Contact me if you have any questions, I will be glad to help.
@@HallmarkPoolSupplies thank you for your help! I’m having serious trouble opening the lid to the pump (in order to clean the pump basket). I tried using the metal lid opener but won’t budge. Are there any tricks to open the lid?
@@HealthyLifestyleRemedies No, but if you can get the lid off make sure you lubricate the o-ring this will make it easier to get the lid off when you have to remove it.
@@HallmarkPoolSupplies thank you, that’s a great idea!
I do not have the switch in top of my pump like that, how do I back wash? Normal setting is 10 but has been on 20.
What type of filter system do you have?
Started the pool this spring but backwash and rinse do not expel water from the waste port. Water stops coming into the filter from the pump. guessing something is broken or clogged within the sand filter itself? Strange because regular filter works fin
To run a test put your filter on recirculate and see how it runs. There are several different things that could be the problem, feel free to contact me I will be glad to help troubleshoot this issue.
Hi Mark, I’m new. What does it mean when the hose up top keep popping off. I started opening on Friday and Everything was good for those 2days Today I come out, turn on pump and the freaking hose pops off, water everywhere of course. I tried tightening it, front -back and it still pops off. I’ve been trying for the last 7 hrs ( because I’m stubborn 😂) . I feel like it’s a pressure thing 🤷🏽♀️. Yesterday the pressure gauge was about 18, I was told ( 1st hooked up last yr)15-20 is good. I’m lost. I got this sucker open by myself and operating but NO CIGAR😤🫣😞. What’s a girl to do
If you have a sand filter, it sounds like you need to backwash and rinse the filter.
How can I address a “chlorinator off, no flow” message on my Hayward salt cell pool? Thanks!
If you have a sand system, it sounds like you may need to backwash and rinse your filter thoroughly. If you put the system on recirculate and everything is fine then your filter is dirty and it is restricting the flow. There are several other things to check but this would be the first thing to check.
What happens if you back wash after adding chemicals? Is it just a waste of chemicals or does it break your filter or pump?
It does not harm the pump or filter, you just waste the chemicals.
I know this is a old video but what does it mean when you can’t move the handle from filter it won’t go to rinse or backwash
It's possible you may need to service your multi-port valve. Here's a video showing you how to lube/repair that valve: czcams.com/video/MsYiWR7bFGc/video.html
Is it normal to use a backwash tank with a water well? 😅
Water wells are not usually backwashed, however you can filter the water. Backwashing is something you do to clean a sand or DE filter for a swimming pool. Thanks for watching.
Do I keep jets on when backwash
When you backwash your jets are already off.
I noticed you didn't do what another pool expert said, that is, he closed the skimmer and return valves, which mine did not come with, so I opened a plug that is for waste water basically, no valves closed, then backwasded then repet for rinse, plug back in I'm finished.
My problem here is my pool will not clear, I have done all the chemicals, they are ok.
I just opened the filter back. Maybe there's not enough or too much sand. I added 4 6oz cups. That's how close it is. I noticed the water on top of the sand seems dirty and the pipe in the middle that states don't let sand get in the tube has sand in it, how will my pool ever get clean when it's shooting out dirty water through the return?
You are not supposed to have sand in the stand pipe of the lateral assembly. If so, then you will have to remove the assembly and inspect for damage. Thanks for watching.
So you are using the waste out line to backwash and rinse? what about the backwash outlet at bottom of the sand filter?
Yes, the bottom cap that I believe you are referring to is the drain for the filter. You only remove if you are draining the filter, or changing the sand. Thanks for watching.
@@HallmarkPoolSupplies Thank you so much!
One question I have is should we add DE POWER to DE FILTER after backwashing? When should we add DE powder?
Thank you
Yes, when you are done cleaning or backwashing the filter you should add DE, the amount of DE that is added will depend on the size of the filter. The label on your filter will tell you how much you need.
@@HallmarkPoolSupplies thank you :)
So I have a lot of dirt in my pool and when I vaccum, it seems some of the dirt returns back to pool from Jets. Can you help?
For normal vacuuming you would vacuum in the filter position. When a pool gets algae infested or is really dirty then you can vacuum in the waste position. When doing this you will bypass the filter preventing the dirty water from going back to the pool, however vacuuming in waste will lower the water level and you will have to add water to the pool.
Thanks so much. I figured that’s what I had to do.
Why am I losing prime when I try vacuum my pool there is no air in the vacuum hose so why after about 15 seconds I lose prime what can it be ?
Make sure you have the vacuum hose hooked up properly, there’s two ends one is stationary and the other is swivel. The swivel end goes on the vacuum head and the stationary end goes on the vacuum plate. I have a video on pool vacuuming here’s the link-czcams.com/video/wUokLi3KQ9U/video.html If you have any questions feel free to contact me I will be glad to help.
I do not get one thing. When the filter gets dirty and we back wash to wash out all dirt. How the system makes that only dirt leave but not sand? Or we losing dirt together with sand?
When backwashing the filter, the dirty water and debris are flushed out. The sand is weighted so it does not go out. However, you will change the sand in your filter about every 2 to 5 years on average.
Might you know how to remove silt
For fine material, you typically vacuum to waste.
@@HallmarkPoolSupplies dont have waste
I dont have rinse on my filter is just handle one backwash and back to filter
Some filters only have two positions, filter and backwash. Thanks for watching.
Mark when I backwash my Hayward sand filter water barley comes out about 1/3 of full blast any thought ?
How is the flow in the other positions like filter, recirculate and waste?
@@HallmarkPoolSupplies it’s good very good runs about 8 psi on filter with strong flow going back into pool and in rinse it’s strong with full flow.
It’s got new sand and new hand valve I bought the whole assy because of the spider gasket glued to the assy from the factory
If you like to troubleshoot further give me a call. I’m available Tuesday-Saturday from 10 to 5 EST.
@@HallmarkPoolSupplies Mark I use dropout flocculant last nite and it cleared it up Woo Hoo
@@HallmarkPoolSupplies Mark guess what the plumbing is wrong I got the pump hose going into return and the return to pool hose going into the pump fitting 🤦♂️🤦♂️🤦♂️🤦♂️
What if there is no rinse on our filter ?
Some systems only have backwash, thanks for watching.
How much pressure can that Haywood filter head withstand without catastrophic failure
The multi-port valve can handle the pressure that the pump puts out, most systems operate between 10 to 20 psi. The valve is rated at 50 psi.
@@HallmarkPoolSupplies I had to up the horsepower on my pump motor because I have water solar panels mounted on top of my garage roof and I need the extra pressure to get it there and back.
What happens if I'm backwashing my sand filter and I see coming out sand from the filter?
@@wifiDOLLARS-d6g Keep an eye on it, if this continues or gets worse then you may need to check the laterals inside the filter. I have a video titled “ Sand in pool” this should help if needed, here is the link for this video. Thanks for watching

@@HallmarkPoolSupplies I just find it odd, because in backwash it comes down the central filter pipe do the bottom, then up between the sand and then out to the drain. Excessive pressure, taking the sand? Or too much sand to begin with, inside the filter?
@@ALCLCFVIS Possibly to much sand , if so the sand will level in time.

@@HallmarkPoolSupplies thanks for your super quick reply, I can't find exactly how much I need to add afterwards. Thanks in advance
What type of filter do you have?
@@HallmarkPoolSupplies Triton II TR-60
The TR 60 holds 325 lbs of sand, but you do not have to add sand after you backwash.
I’m still trying to understand all this. So run “WASTE” every time you backwash as well?
After you backwash then you rinse the system, not waste. Check out my video on basic filter operation, it goes into more detail on how to operate the system. This should help, thanks for watching.
@@HallmarkPoolSupplies Awesome! Thanks for responding! I watched it. Totally helps. Appreciate it so much!!!👍👍👍
What if the water being sucked in seems not to be strong but throws it back in pool fine . Is this normal???
There are several different things that could cause what you are describing, feel free to contact me and I will be glad to help.
@@HallmarkPoolSupplies : But I wanted the info here and not on the phone!!! 🤣 🤣. I have the same consern and now no online answer! 😭 😭
You may need to backwash and rinse again, if the problem persists then put the system in recirculate, if you still have a problem then you may have a clogged impeller. If the system runs good in recirculate then you may need to change the sand in your filter.
@@HallmarkPoolSupplies: My pump is brand new just installed Sunday and I don't feel too much sucking action but pumps out good.
@@Android_Warrior Have you tried running your pump in the recirculate position? Your pump is new but what about the filter or the sand? You also what to make sure that your system is hooked up properly (hoses).
Wait. Those return jets are facing up. I thought disturbance at the surface was bad and the jets should be facing down?
You want to have a little wake at the top for surface debris. Thanks for watching.
