The only pressure pipe i use is for bottom drains as they are burred anything else I'm more than happy with normal waste pipe and as you say you are never going to blow it apart off a pond pump save your money and use waste pipe
No problem i keep seeing people spending hundreds on pipe and fittings they dont need. maybe im just tight on the cheap end i see so many people useing cheap flex pipe as well that will come back and bite you on the ass at some point with a huge water loss.
Great video, I’m just doing my pond and would not put pressure pipe on it unless it’s under the pond with say 10 tonne on water on top of it. Most pumps are about flow, the pressure is the resistance to that flow, if you have a blockage then not even waste pipe will break, rather a seal will fail or the pump would stall or just tread water. Thanks again for video
Yes 100% waste pipe is a pretty safe bet as long as it’s installed well and you can’t physically break it etc. thanks for comment sorry for delay in responding!!
Absolutely loved this video and the advice, too much 'recevied wisdom' in the pond keeping hobby and it's nice to see some science to back up your advice. Definitely subbed.
Hi, food for thought. For me it’s not about the water pressure but mechanical strength and temperature. I was fortunate enough to obtain a number of lengths of 1.5” & 2” ABS pressure pipe and a mixture of sixteen 1.5”, 2” and 2.5” industrial quality ball valves. ABS being better in cold conditions than PVC. My mid level filter upgrade detailed on my channel is done with the the ABS connecting on to existing PVC pressure.
Hi just building a pond, I’ve got four return two at the front side and two rear back, to cut down on pipe could I put the two into a T and run one pipe to a valve? Same with the back, I’ll be using a 10000 vari pump
Good idea with the multiple inlets it will help with the flow direction. If you are using the black liner connectors, you can use 40mm waste pipe bends like the 45 degrees or 90 to aim towards the base/sides/shelve to move debris off towards your pump or drain. If you want the flow faster, simply ad a yamitsu solv weld hose tail to the end of the bend with a reduced outlet to add some pressure to inc the flow cheers for the comment
Thanks for another useful video. So if I have hose rated at 4 bar it should be perfectly OK to use it to connect my pond pump to my pressure filter rather than having fairly unsightly PVC pipe running across the pond?
Pressure is just rho *g* h or density x gravity x height . You may have additional pressure due to long length frictional resistance or if the pipe gets clogged with debris. But in general head height is the driver
Hi mark thanks for the comment. Yes you are correct you will get some pressure over long distances, definitely for industrial applications as for what the pipe is for but realistically people who use it in ponds the lengths of pipe used is really short in comparison, even still the pressure won’t amass enough to warrant 10bar pipe. Even if clogging or if a valve is shut most pond pumps don’t have the pressure as they aren’t really designed for high pressure.
Hi mate excellent information but a bit off topic iv just changed liner in my pond I put the koi In Swimming pool wile I did the pond for a week they was fine I had all the filters running on the pool kept the water parameters the same all the time the fish are now back in the new pond with most of the same water from old pond all water is good but seeing the koi flashing any ideas thanks
Hi Lewis, if the water and filters are the same, and you have tested ammonia and nitrite and all the levels are spot on, you may find that the fish have some flukes (external parasites) on their skin which is why they flash. Its common when the water warms up from winter. Its really important to make sure the water is 100%, your fish usually have a natural immunity to most parasites which they can fight off them selves, but they can struggle if stressed (usually from poor water etc) If water is good i would recommend a standard dose of an anti parasite treatment for the entire pond to kill the parasites & eggs.
@@thep0ndman hi mate thank for getting bk I was hoping you wouldn’t say that lol but here in south wales temps are up n down atm I was hopping it was temp change it doubled with in a week of me putting them in to the new pond n now today big temp drop again but yes like u say warmer temperatures bring out these parasites 🤮 do you have any idea what I can use to treat and something that doesn’t effect my biological side of filter thanks again👍
@@thep0ndman also may I had my tap water is showing 0.5 salt level for the first time ever straight out of tap so my pond is sitting at 0.5 salt this can’t be good
I would use just a very basic treatment for now so nothing to mad, this is usually a good all rounder (Blagdon Anti Parasite 250ml-1ltr). Strange with the tap water, in all fairness the parasites wont like the salt levels. Which test kit are you using (has it expired as they don't last that long when opened, they can give dodgy tests sometimes) have you had salt in the water before?
@@thep0ndman I have a Pond lab 200 I think it is and I will check tha date on it but it’s fairly new and I have had one or 2 dodgy reading with it on the ph other day to be honest but then reading fine and yes I did put a little salt in the pool before the water when back in the pond only hlf a cup but not knowing the tap was reading a 0.5 any way so that then took my pond to way up to 10 so I did a water change to bring it back down to 0.5 but this didn’t help has iv put lots more fresh water back in to the pond now than originally planned but water is all reading ok
Hi again great video my pond is over 30yrs old and I used 40mm waste pipe then and it's still going strong 👍
That is awesome! Many thanks!
The only pressure pipe i use is for bottom drains as they are burred anything else I'm more than happy with normal waste pipe and as you say you are never going to blow it apart off a pond pump save your money and use waste pipe
100% agree thanks for comment sorry for delay!

So glad I got this in a recommend video, just in the middle of building a pond now.
Great to hear. Hope the build goes well!

Yes 100% agree abs much better for high or colder temperatures!! Where did you get them from if you can remember thanks for comment sorry for delay!!
Another great topic covered well loving the contents
Cheers Gary sorry for late reply!
Hello, would you say standard 4 inch push fit soil pipe is ok for the gravity fed system? I’ve put it in anyway and it’s working really well.
Yes should work fine.thanks for the comment

It's all about safety not bad advice.. Do it right once
Yes agree to definitely get it right the first time thanks for comment!
am using PVC plumbers pipe from BNQ works a treat and it’s cheap. Pump fed (8000) into a multi bay filter, two returns 🤷 simple 👌
Thanks for the comment. Yes 100% if it works then why over spend…?
Thanks for another useful video. So if I have hose rated at 4 bar it should be perfectly OK to use it to connect my pond pump to my pressure filter rather than having fairly unsightly PVC pipe running across the pond?
Yes, absolutely but garden hose is prob too narrow for the diameter and flow rate
@@thep0ndman Great! It's not garden hose though, it's got wire embedded in it and 1.5 inches in diameter. Food grade. Thanks again

Have you never heard of hydrostatic head. For every foot of depth you get just under half a psi
That’s interesting cheers
