[@colemanneedles3620]

I appreciate that you actually describe what each part is called.

[@writingetc]

I don't have enough space to put my dishwasher drain vertically, so this was very helpful for installing that drain horizontally. Great idea.

[@renhoek7531]

The dishwasher connect should be fitted at a 45°. And a sure vent at the clean out. Pretty much just twist the dw wye to 45° and take off the cleanout fitting and put a wye with a sure vent on the vertical and a cleanout cap on the diaganal and youre set. Very good job dude. Also remember to have a minimum 1/8" slope going towards where the waters going so it actually drains. Again. Good job. Cheers

Tip: The best way to test for leaks is to fill the sink with water and then let it drain. This will expose leaks more than just running water into the sink.

[@aaron74]

I think you need the dishwasher discharge port to be on a vertical piece between your drain and trap. If it works fine on the horizontal I wouldn't worry about it, though.

[@BeckVMH]

@Aaron Kaase... That is my understanding based on researching my attempt to connect my dishwasher to the existing pipes (after getting rid of my garbage disposal). I was trying to determine how to tie the dishwasher drain line to the existing pipes and that required the piece with the port. If situated as shown 4:08, on the horizontal plane, there is a chance for back wash. This may work, but might not be best or code. Also, told this by a licensed plumber assuming I understood his explanation. But... I'm a novice. Just a recommendation to viewers to research this and draw your own conclusion.

[@kylebutler3404]

Thanks for posting this it helps a lot. my setup is almost exactly like yours and it is great to be able to visualize what I need to do.

[@Wigglythegreat2]

Nice video man. It took me a while to figure out why I had a leak on the exit end of the trap until I realized I was using a washer when I didn't need one there. Doh!

[@dennischristen8402]

I have your a similar setup with only one drain but I was wondering about the air where you have to clean out I have an heir that goes out to relieve the pressure I wonder why you don't have that

Hey. Nice video. Top hat basket gaskets were installed upside down. Should fit inside the drain pipe and sit flush on the cross section of that same pipe. It may not leak but it’s just weird lol

[@charlessansom4214]

I have had problems with my dishwasher draining through the disposal. I think if I install the tail piece with the dishwasher drain and plug the drain on the disposal it will solve the problem. Thanks.

[@mudder4660]

Is the first (right) top hat gasket correct, it looks pointing up versus down into the pipe?

[@averydavisTV]

Nice video. 9.8 out of 10. I wish you would’ve hook up the dishwasher line at the end

[@drich6816]

How are you venting then? I'm trying to install my sink today and confused on it i need to vent as I have a 3" drain coming up from the floor

[@jeffseeley2628]

Hi do you have a video showing how to pipe a kitchen sink from a left to center drain.

[@patrickgrimes8964]

I really like your videos, they are some of the finest on the internet. Excellent instruction and clearly explained. Also everything is well lighted so it's easy to see everything, a huge plus. One question, I see you're not using a garbage disposal, is that why you have the special strainers? Do you not like garbage disposers?

[@leightongalleries6057]

They are no longer legal in a lot of places, and the list is growing. Probably why.

[@Bakin]

The fact that the waste line going through the floor is much larger in diameter than the line to which the garbage disposal discharges, the line going through the floor will not be full and because of that no siphon affect will result when discharging. That is why that line had been deliberately over sized; to prevent a siphon since there is no vent in the island. That is why the installer says it works fine. That’s my thoughts.

[@johnrowe6649]

Good video dude 😎

[@nitinbagade3530]

water from this tank can send on higher floor due to pressure difference or by using another pump.

I clicked on the link for the kit and ordered it, but there was no p trap adapter like you mentioned. I realize this video is 3 years old, but the link still worked so I assumed it was good. I have been unable to find an adapter like the one you mentioned anywhere. Any advice?

[@rockymntnliberty]

Looks like that drops down into a basement or crawl space, how is the line vented?

[@joshm5816]

You are correct. The drain line is not vented. This could be corrected with a simple AAV 4 inches above the trap weir. Disposals do not vent a dishwasher. That is called an air gap. Totally different.

[@travislogsdon8691]

[@frankpyon2115]

Thank you for the detailed video and the instructions. What if the garbage disposal was installed?

[@BenjaminSahlstrom]

There is usually a dishwasher connection on the garbage disposal itself so that is where you would connect your dishwasher in that situation. amzn.to/2NukoZY Look at the pictures for that link and you will see the dishwasher connection. Thank you for being a subscriber! Blessings from MN!

[@ronaldzeoli7528]

I would used schedule 40 and glue joints. With one or two brass nuts at the sink baskets. This stuff your using does work but is more Likely to leak down the road

[@edmottwiler7116]

this is an excellent example of how NOT to install a sink drain. the P-trap that ties into the larger drain (without a vent) has actually created an s- trap which is NOT allowed by any plumbing code because it will siphon the waste out of the p-trap rendering it useless. also never connect the waste from the dishwasher to the disposer or the drain line. the waste from the dishwasher ALWAYS connects to an air-gap fitting above the flood rim or the sink...WHY you might ask, what happens when your sink stops up with dirty water and backs up into your dishwasher full of dishes that you assume are clean?

[@BenjaminSahlstrom]

Exactly! This example was not to code as you mention but it works perfectly. It does not siphon even when you drain a full sink of water since there is enough space in that short piece of 2" pipe going through the floor that there isn't enough volume to create a vacuum since the line is vented tight under the floor. With the dishwasher situation again you are correct but the likelihood of the backup happening in that way is very very low. Again, technically you are correct but this method does work.

[@efrainvalle6573]

excellent video... thank you!!

[@noeltorres5239]

I have a faucet like yours what size is fitting for the water lines?

[@BenjaminSahlstrom]

Before you whine about there being no vent please note: There IS A VENT. It is hooked up under the floor and no, it's not to exact code but it IS VENTED. NO ISSUES WITH THE SETUP WHATSOEVER. The only reason I did not put a typical loop vent under the sink was to save space and I realized that there was some small potential of needing to add one later if I had issues with siphoning. Using 2" instead of 1 1/2" for the drain helps prevent the siphoning issue for the couple of feet until the drain is vented. This video was meant to show how a vent can work in a unique situation. If you want your setup to meet code technically then you'll need to make a loop vent under the peninsula/island and provide cleanouts adequate to maintain the system. I explain it more in this video: kzbin.info/www/bejne/bX2bgImFi9utd6M Thanks for watching!

[@erictold]

It's a "S-Trap", which is not legal. Even if you have a vent under the cabinet, you need a vent at the tee, not under the cabinet. You don't need the clean-out because you can easily disassemble the trap whenever you need.

[@donaldlee6760]

Great video. We have an old 1960s kitchen with tile countertop. Did you DIY your black quartz countertop and stailnless steel double sink, or is is this generally a job for the pros?

[@naveenmehta9973]

Nice job

[@Dave-jc6ky]

Hi, thanks for the video! In our situation there is a single basing sink with of course a single sink drain. Can you advise parts needed in this regard with one sink drain instead of a dual basin sink drain arrangement? Is the tail piece for dishwasher designed to direct water towards direction of the drain/trap line?

[@beckyschwantes5287]

The piece he had all the way to the left has a baffle so water is directed down and the pipe should be at a slope to keep the dishwasher drainage headed for the p trap So if you only have one basin they make a tailpiece that has a dishwasher drain nipple on the vertical drop. Just come down hit your P trap and into the sanitary tee. Put a wye fitting on top on the sanitary tee. The vertical section u will install a vent and on the 45 degree you will install a clean out

[@alansmith7626]

where did you get that sink! I love it!

[@jonathangreenawalt5724]

you should put in an air admittance valve in too.

[@jonathangreenawalt5724]

@AGENT 47 I was referring to venting after the p-trap. The purpose of the air valve is so that a vent stack does not need to be installed. Without some sort of venting the chance of siphoning will occur draining part of the p-trap allowing gasses to seep past and up the drains. Not to mention according to Title 24 CFR § 3280.606 Traps and cleanouts. (a) Traps - (1) Traps required. ..."All traps shall be effectively vented". (Source: Law.cornell.edu) Unless the vent closest to the p-trap is within the maximum distance according to your area. So installing a air valve where the pipe cleanout plug is advised. The drain tap into sink drain is fine, according to PA a high drain loop is satisfactory, but still look at the code for your areas. The single p-trap for these drains still needs venting. Also I am unsure, due to I am unable to see clearly the p-trap/drain connect venting also needs to be 2 pipe thicknesses away as to avoid creating an S-trap instead. please see: waterheatertimer.org/images/andi-plumbing-add-a-vent5-23-update2-585.jpg

You need to plug the tailpiece until you are ready to hook it up. It may have come with a cap but if not you can buy one.

If the hose was plugged with grease I would recommend trying to reduce the amount of grease going into the dishwasher in the first place. Grease never plays well with drain systems.

[@kilmer009]

@@namita9031 No grease or oils that solidify when cooled (animal fats or coconut oil) should ever be dumped in your drain. Collect it in glass jars until full, then throw it out in the whole thing out into the garbage.

[@tennies]

I believe you should have had an air admittance valve (aka Studor Vent or cheater vent) basically where the cleanout is.

[@BenjaminSahlstrom]

Joe Tennies You would be correct assuming that you don't have an island or peninsula vent already set up as I do. If you use a peninsula/island vent then you don't need an air admittance valve. The reason the latter is not used more often is because in most states they don't satisfy code requirements. Thanks for your comment!!

[@maxcondra4991]

Either an island vent or an oversized 3 inch pipe where the top of the pipe acts as a vent. Cheater vents are not great for garbage disposals or dish washers unless they are higher than the spill line

[@ep4637]

Joe Tennies he's brought in 3 inch waste . That in Lew of a island waste and vent system. 3 inch so no vent required

Wheres the vent pipe?

[@billwardhaugh2563]

Bill Wardhaugh. 2018-01-23: Thanks for a super video and clear precise instructions - easy to follow (good teacher). My problem in our new kitchen is this: The Contractors site Manager insisted there is no problem after he did the 'swirl test' (half fill the sink, remove the plug, and when you see the draining water swirl, it shows all is fine) Every time our washing machine discharges water it flows up into the sink (about half inch deep). Needless to say this is dirty water and we are sure should not be in the sink. It never happened before. The 8 inch long horizontal pvc waste pipe after the U trap is one inch higher than the pvc pipe entering the U trap which has the washing machine inlet on. I believe this is the problem as it's easier for the water flow from the washing machine to go up into the sink - then go out the normal waste pipe. I would appreciate your comment on this. Thanks for reading it.

[@BenjaminSahlstrom]

I've never heard of the "swirl" test. Sounds like a good way to convince someone it's working when in your case there are still problems. It's hard to picture exactly what you have going on but in any case you should not have water coming back up a drain from another source. It sounds like the drain line that the sink and washer connect to may be restricted somehow so possibly cabling that out would help. I'm assuming there is a separate washing machine standpipe or were you meaning to talk about a dishwasher connection like what is in my video? Hope you get it figured out!

[@renhoek7531]

Either you have no venting or it could be that the wye connected to your dish washer is backwards and shooting the water up the slope instead of down into the drain. As a plumber, i have never heard of a swirl test. Dont use that plumber anymore lol
