Richard helped a homeowner connect his bar sink to the main sewer drain for the house with an electric pump. The pump was needed because the main drain line is located several feet above the sink. Afterward, back in the workshop, Richard showed some additional devices for ejecting sewage and wastewater from basement plumbing fixtures.

love how he used the wire to stop his saw blade from coming into contact with the foundation
Pro-tip: use a scrap piece of 1x4 to keep from sawing into the live electrical wires.
Thank you so much for adding this! We've been having trouble with our new basement bathroom sink and I'm sure it is because they didn't install a drain pump. Going to update and add this.
This was so helpful if I ever come to a situation where I need to connect a drain for a basement sink.
I love how a 2:34 he smacks the saw teeth against that electrical wire. 🤣🤣
Anybody else laugh when he sliced into the romex sheath with the handsaw?
Oooops!!!
More like cringed!
Didn't look like he exposed any copper, actually I couldn't even see the hot wire
I actually paused the video, to see the first comment about the romex. and here you are on top of the list!
He's a plumber, not an electrician :)
That is the greatest video ever! (no sarcasm). Showing how the control the discharge of the pump so that it doesn't work faster than the faucet was amazing. I enjoyed how he he showed the one-way valve too. This video was very eye-openning. I live in Tucson and it is rare to see a basement home; I was wondering how water gets out of the basement when the discharge pipe is higher than the initial pipe (drain). I understand that the pump is powerful and can lift water 14 feet. Amazing tech.
true, but what about toilet drain. how to push a heavy dump 14 feet up 🤣🤣
Sewer injection pump 💪
2:34..... woiw wow that was crazy!
Is that an autographed photo of William Holden? lol
This is really helpful, thank you.
Fernco band BARFF!!!!!
Not a plumber, so I have a question. Around 2:48-2:50 when he installs that T-piece into the drain line, how does drain water coming from upstairs sink, toilet etc. not flow down into the drain pump instead of simply flowing out to sewage line?
A. That drain line is too small to be a Waste drain, so no solid waste going down it.
B. The connection is lateral, coming in from the side, same height. It is also angled following the flow direction of the main drain. So...
C. Fluid dynamics... or simply put, water velocity, pitch, and gravity carry the water downhill. Any little bit that does make it's way sideways into the pump drain will just get caught by check valve.
What is the potential for the drain to backup to other places in the house behind that patched-in Y?
Thanks for this very informative video.
Do these laundry tray pumps need to be vented?
Yes
Using a No-hub coupling on PVC is not allowed even with transition fittings. Use a slip coupling.

I would get tubing and just drill a hole and pump the water outside to water plants.
They make it look easy, But I'll pay a plumber to do it
And when that plumber arrives to scope out the job and goes to his van to give you an estimate he will be watching this video before doing it
@@herb_nbeatz2135lol probably true
No way
What do I have to do if the pump was going on and off, and now it won't drain the water? Is my pump shot? Do I have to buy another one?
So the pump should be a constant sound, not a pulsing noise?
I have one under my sink but when I'm not using the washer it still keeps like running like making a loud noise
I have an old cement triple sink. My washer has, for as long as I have owned the house, gone thru a pvc pipe from the sink drain, down 4 ft over to an elbow to 3" to 4" rubber adjuster placed directly over the floor drain. Now that I am selling, it is an issue. Is there a way to attach the two for a closed flow into the floor? I am not breaking up and digging up the floor. I like the way it is for super easy access to clean/plunge that floor drain on a moment's notice and on a regular basis.
Is a vent needed?
I want to do something similar but with a dishwasher. I have a kitchen in my ground level basement and want to install a dishwasher unfortunately the current set up will not allow enough room to put one next to the sink. I'd like to beable to run the water along the wall to a drain in the laundry room. The drain line would he hidden so it wouldn't be a issue. It's about a 20ft run.
The dishwasher pump should suffice to move the water to a higher drain.
how about the vent?
Any plumber here.
Can I use this drain system to have a 2 component sink in the basement for my restaurant?
Inspection will be made according to the rest of the plumbing
I would expect you’d need a pump that can be set up with a continuous waste (similar to how a garbage disposal might be in a a kitchen) This pump did not appear to be capable of that but I’d expect one exists. Im a first year apprentice (in other words, I’m no authority on the matter) and im replying 5 months late so I’m interested to see if you’ve addressed your situation and what was done.
How many horse power is the pump you are using. Will a 1/3 hp work to pump like you have? I t from washer to utility tub where it is hooked under utility tub in basement. Pumps up, in a 3/4" pipe though. Was there previously with same type of system. I m replacing it with a outtake of 1 /2" now. The other had a 3/4" out. Will this work or will I have to convert 3/4" pipe over to 1 1/2"? I am wondering if I have enough hp also? Thank you
When I was a kid this is the way the washing machine was drained, machine went in to the laundry sink then pumped out from there.
Does no one else notice how his washing machine waste is like 5 feet off the ground? @4:38
Modern machines are spec'd to pump that high. Limit is right around that number though based on the manufacturer.

Don’t even!
Lol ⚡️
What basket strainer did you use, I try few and are to long?
I have a similar setup in my basement for the washing machine. I'm trying to change from a Polypropylene sink to a stainless steel sink but the basket strainer won't screw into the pump inlet. It looks like the threads are different. The old sink had a tail piece that the pump screwed into. Any ideas?
Call a plumber
Care to share the brand name of this pump?
Which brand pump is this?where can i buy this?
Does this work with electric?
What about the VENT?
Jamshed No vent needed with a basin pump, the air in the pipe will just get forced out any of the other vents for the rest of the fixtures in the house.
Jamshed I’ve been looking into these, the instructions say no vent is required
Cool. Now remove the illegal above-ground rubber clamp and put on a proper steel banded no-hub coupling.
ScubaCat3 not to code does not equal illegal. Also, every municipality has different codes. Do you know where they are and what the codes are for their location?
ScubaCat3 exactly! And ditch the rest of the setup. None of that shit would fly here in Illinois.
@@mikeybmx5330 the hell? How else do you have a basement sink in illinois then?
I thought you would need a p trap there?
hmmm, should the T face upwards? i mean why not? its pumping anyway, rather safe than sorry
Finishing my basement and need to use this type of setup. Can you hook a garbage disposal up to this as well?
No
😂😂😂😂
Lmfao the wire at 2:33
If I connect a utility pump to a stainless sink, should I ground the sink?
My sink is not grounded and is attached to a pump. A plumber did install.
Anyone know the pump model?
Cool
Where is the vent?
i would cable snake those drain lines they are more than half clogged! yuck, needs some attention

Can I drain this pump into an existing laundry drain pipe?
Problem is that the existing utility sink beside the stacked washer dryer (washer on top) is just below (floor is two-three steps below) foundation wall and the drain that goes back into house. So can’t install p-trap without raising it up. Current sink drains to open Rubbermaid container with sump pump going to the washer drain. Not to code and smells.
I bought this sink pump but I think the only way to drain it (and be code compliant) will be direct into existing laundry drain and then re-direct washer drain directly into sink? Does this sound right?
Anyway to combine both directly into the laundry drain?
Call a plumber plz
Which Laundry Tray Pump are you using in this video. Thanks.

Copy that. Thanks for the video.
Junk
HE JUST BLEW THE OPPOSITE SIDE OF THE CHECK VALVE,, EVEN ANT WONT MOVE WITH THAT BLOW
Coming off of the pump can you do your ball valve first and then your check valve or no????
looking at the video it shows check first, then valve
Personally, I think putting the ball-valve first and the checkvalve second would actually be a better installation because the check valve would then be closed more quickly and securely by the full weight of the water in the vertical pipe without it having to trickle back through the mostly-closed valve first.
I would never put a boot behind a finished wall. Maybe not today or tomorrow but it will leak on a horizontal run. Just saying.
I never dry fit pvc because of shrinkage.
You’re not a plumber
were can i buy one like this?
homedepot cheep don't do it
Do you have to buy sink and pump separately or is this system sold together as I cannot find it anywhere
Is there a system like this for basement washing machines
404 liberty pump
why not use a globe valve if you know you are going to throttle the flow? Ball valves are not supposed to be throttled.
i was thinking maybe cost, but just looked up PVC globe valve, and found lots around $10, learned something today Tripnotyst, thanks!
what? that is opposite of of what you're saying .Ball valves can be throttled but globe valve are meant to be opened all the way or closed .
Did it even crossed your mind that licensed plumber on national TV know what he is doing?
The globe valve is used for throttling flow control. Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve. The flow pattern through a globe valve involves changes in direction, resulting in greater resistance to flow, causing high pressure drop.
Ball valves are an excellent choice for shutoff and control applications, where they are often preferred to gates and globe valves, but they lack their fine control in throttling applications
@@pawelgatorade ball globe,same
Those pumps are hard to find
Easy to find Any Home Depot Everbilt 1/3 HP sink pump Around $250
Mini heart attack @2:34
YIKES! not a good look...
2:32 almost cuts through the electrical wire 😬
How could i add a dishwasher to this same setup?
Scott Swim draining the dishwasher into the utility sink would be the most simple solution to that.
What would be a fair price for a plumber to do a job like this? I have a job just like this I want done.
Just did one about 1500, it was a pretty long distance though like 50 60 ft, that might have been a little cheap
@@jdahighroller9389 About $22,500 or so for a plumber.
@@lukedrifter1 Im in Louisiana... I need to go somewhere and get properly compensated for my skill sets
Could a dishwasher be added to this setup?
Only if it uses water =) dishwashers have a pump, that may go high enough, depending on your placement and height to main drain line. i have mine pumping about 2 feet above the top of the dishwasher temporarily until i completely remodel my kitchen, and it blasts out!
is there anything on the market for a wash machine? I would like to install electric dryer and wash machine in the garage but I don't wanna open the concrete just to run the sewer pipes
Washing machines already incorporate a rather robust pump to discharge their water. I've never seen them try to pump to a ceiling height before, so you'd need to contact the manufacturer to find out if this would work. The other alternative is to simply install a cheap plastic basin sink for your washer to discharge into, and then utilize a pump like Richard featured in this video.
and hopefully your garage is heated all year, else you will freeze the lines, i like the basin sink idea
In a different video, Richard uses this system for a washer drain. Watch this video here: czcams.com/video/HW-_WA1Psi8/video.html
Why not just use a pump that matches the flow of the sink? Why use an oversized pump and then restrict the flow?
Not a lot of selection when buying pumps like this. No big deal to restrict the flow of the water. Is it perfect/ideal? Not necessarily, but the pump will still last for years and years set up like this. We have had one for 10 years set up just like this, still going strong.
They probably don't make very many sizes of these pumps/
Better than undersized.
All pumps need a device that can change their flow to meet field conditions because each pump is manufactured to meet a range of flow conditions. If you think about it, even the sink flow conditions can change depending on how "open" you have the faucet.
@@sngehl01what i'm confused about is if I still have to vent the sink if I do this?
Saws into romex lol
One of the most important features Richard failed to mention was that no trap necessary and more importantly, no vent needed ! Can be costly and Inconvenient to install or even locate a vent .
I was wondering about the vent situation. So with these laundry tray pumps they don’t need to be vented?
@@michaelgelatt8995 Trap and vent is a part of the design of this pump unit. i believe it has some sort of an air admitting valve kind of design for vent..
where can I buy a pump like this anybody have an idea I need help thank you
Amazon or ebay, and probably local hardware store but look for a laundry tray pump in the search and it should come up
How much does the pump cost?

Omg am i the only one that noticed how high is the washing machine drain?
Unserviceable install.......great work Buddy. How about a frickin union
Can this be used with a double sink?
Yes, I have one on a double-sink. The drains are connected in a 'Y' before the pump.
@@djcsrdo we still have to vent the sink?
Teflon tape draped over the pipe opening, no 1/4 turn when assembling the PVC pipe, man, I'm a complete armature and I know that.
Armature? What's that?
its a Joke, so if the sink takes 10 minutes to fill it will take 10 to drain.
Stop using plumber's putty! Throw it away, use 100% silicone.
