The replacement kitchen sink I installed was substantially deeper and the drain opening in the sink was offset to the original... which didn't allow me to merely reuse the same tailpieces & P bend trap and other PVC tubes & fittings that had connected the original sink to the 2" Sch 40 PVC tee & pipe that was buried in the wall studs.

Rather cutting into the wall to lower the 2" tee so to accommodate the deeper sink... and then being able to use the standard tailpipe & P bend trap parts, I used 'flexible'/adjustable 1 1/2" pvc tailpiece & P bend trap and double slip couplings to connect the sink.

I will be selling the house in the next year and want to confirm prior to placing it on the market whether using these flexible pvc connectors between the sink and the 2" sch 40 pvc is not prohibited by the plumbing code.

Thanks,
Russ

Hi Russ,

How much lower is the traps tailpiece then the wall stubout. It's not the flexible connection that has me concerned but the backfall on the drain. Waiting on you. Tom

I'm not sure what you mean by 'backfall on the drain'... but it doesn't sound good.

The total straight drop from the point the tailpipe is attached to the sink to the bottom of the "J' bend is about 14". The distance from the bottom of the "J' to the point where the 1 1/2" pvc joins the 2"PVC Tee is about 10"... so there's about a net 4" of height between the bottom of the sink and where the 2" Tee is located in the wall.

Does this information help you? Thanks, Russ

Hi Russ,

House drainage depends on gravity to move the water. This is obtained by slanting the pipes toward the sewer main. This slant is called fall/ pitch/ slope you can take your pick. Backfall is reverse pitch and is not good plumbing practice. Backfall=problems.
Having said that if the hookup's working and the wall stubout's lower then the bottom of the tub I see no reason to tear the wall up and lower the stub out. I do hope you don't have a disposal in the sink. If you have I foresee blockages in the future.
Of course you realize that the correct thing to do is lower the wall stub-out.
Regards, Tom

Tom... thanks for the explanation and the guidance... I've put in enough drain lines in a home we finished to be very aware of the principal that water runs downhill... its just that I hadn't heard the term backfall referring to when the 'downhill' runs the wrong way. If you leave the plumbing business... you could make it as a fortune teller. We do have a disposal and I have become very careful what I put down it and how much I put in at a time. I keep a plunger just outside the kitchen/garage door which has been instrumental in opening the drain line numerous times.

Hi Russ,

When you mentioned the toilet plunger being used, I became a bit concerned about the health of your plumbing. But before I go into that, let me comment on the flex drain line you put in. As a rule of thumb, I always check on the alignment between the tail piece of the "J" and the location of the tee you're trying to connect to. If that distance is greater than 1 tenth of an inch, I normally tear out all the plumbing and install all new parts. Incidentally, you should never reuse existing trap parts. Over time those part become contaminated with disease entities and then you're looking at potential health problems. I ran into one fellow that reused contaminated parts and ended up with congestive hepatitis "C" in his respiratory system. He survived, but will be on a ventilator for the rest of his life which probably won't be a very long time.

I hope your house is built over a basement or crawl space, because what you really need to do is tear out all your plumbing back to the main drain stub and re-plumb your whole house. New parts will ensure that you don't get deathly ill.

Now back to the toilet plunger. Never, never use a toilet plunger for a toilet and a sink. Just the thought makes me cringe with disgust. Think about the products that go down your toilet and then think about introducing them to your kitchen sink. If that doesn't stop you, I guess nothing will. I keep a stock of brand new toilet plungers on hand that will only be used for the sink. And once I've used one, then I toss it. No sink plungers are ever used twice in my house. No, no, no! It's a lot cheaper to buy a new plunger than go to the hospital with some horrid biological disease.

There are other areas you need to think about before you try to sell your home. Number one is carpet. Carpet can and probably does contain bugs and disease entities that could kill. You should tear out all carpet and replace it with brand new hypoallergenic floor coverings. If you have ceramic tile on the floor, that too can be a problem. Tile is cold in the winter and so germs are apt to thrive on the surface and in the grout. While hardwood flooring is better, it’s only better if it’s the old style of flooring, not the new fake stuff. The fake flooring has the same problem as floor tiles.

I’ll leave you with one last thought. I’ve only owned three homes over the years because of the cost of getting them ready to sell. In each case, I found it was cheaper to have the old house torn down and replaces with a brand new structure rather than pass diseases on to a new owner. I’d advise you to have your home demolished and build a new one to sell. Then move to another city just in case the building contractor introduced some disease integers. You never know what someone might sue you for that was actually something the contractor did while rebuilding your old home you planned to sell.

Good luck.

Hi Farmout

Sorry bud, but are you nuts or something?

Perhaps you enjoy scaring people that have no idea about plumbing?

Hard to say from here, but I'll tell you what... almost everything you posted here is nonsense!

I need to be very clear here as many people will be reading this thread and they need to know that you must be a paranoid germophobe or something like that.

Your last paragraph is the most foolish thing I have ever read... period!

I will NOT get into a debate about this with you and will quickly have any additional posts by you deleted from the page.

If you post any more nonsense like this on the plumbing page I will chat with the owners and have you banned from the site, OK?

Mark

AMEN. I just didn't have the b%*:s to say the same thing. Noted this was the first post .
