Water Drain for Bathroom Vanity

I am installing an Ikea vanity and sink and ran into a snag. The obvious being the metric drain pipes that come with the sink don't match the imperial pipes and the supply lines from the faucet are about 1/2 an inch too short but those are easy ones.

I uploaded a picture of the drain pipe coming from the wall and I wanted to use the same pipe but the drawer in the vanity butts up against it.

My dumb question is would that union joint be glued to the drain return in the wall?

I tried to un-screw it and it doesn't budget. I don't want to damage the piping and thought I might have to use a hacksaw to cut it off in order to attach the Ikea p-trap to the drain.

Would cutting it be my best option? Are those union joints typically glued in place?

It is likely glued. If you do cut it off with a hacksaw, be sure to sand off all the burrs on the inside of the pipe. Failing to do so will cause hair to get snagged and eventually plug the drain.

Hi Jason:

Many people have the same problem when installing an Ikea vanity. I personally have dealt with many of these situations. The best solution is to cut the ABS pipe close to the wall and install 2x45 degree elbows for more mobility, they will help you to get your Ikea pipe closer to the wall. Also you'll need a rubber pipe with metal straps, just in case it doesn't go all the way down. At Home Depot they sell an ABS reducer for your Ikea vanity, but it doesn't always fit perfectly, that's why people use the rubber sometimes.

If you need an extra hand, don't hesitate to give me a call 613-302-4000.

P. S. I will also take the opportunity that you're installing a new focet and put some valves in those pipes.

Thanks.

Carlos.

Yes it is most likely glued. You will have to hacksaw it, but make sure you leave enough so that you can put on your replacement piece. If you cut it too close to the wall, you may not be able to put on the replacement piece.

Yes all the connections are glued and can't be removed. The connection on the trap itself can be unscrewed, you can see the threads. The ikea pipes are about an 1 1/8" and no one makes an adapter to our pipe sizes of 1-1/4, 1-1/2 and 2". The solution I use is a what's called a fenco fitting. It's basically a rubber tube that gets clamped around the pipe and the 1-1/4" size can be squeezed down for a water tight fit.

I put that fitting on the stub coming from the sink and throw out the ikea white p trap. You can't get parts for it and just feel how cheap they are anyway. You only have about an inch to sink your black p trap closer to the wall. If that is not enough I have had to notch the back of the drawers to get clearance.

Hi Jason:

I can't see the picture clearly where I want to look at it, but it maybe glued in place since you are not able to budget. I would cut it all off and start fresh, leaving enough original pipe left to re-attach it. I would purchase a ABS P Trap Drain pipe with a rotating seal so you can get the maximum movement since you are tight for space. Do not glue the P Trap where you see a thread & nut for tightening. Always Be-burr your joints & do a dry run first fully assembled. mark your pipes with a magic marker lines, then glue them matching up the magic marker lines. You have less than a minute so, you have to be quick.

Good Luck.

Thanks for the replies everybody. I found some flexible couplings and adapters (http://www.fernco.com/plumbing/flexible-couplings ) that I'm guessing a local plumbing store will have. The big box stores didn't have anything that would do the trick.

I'm going to cut a notch out of the drawer and use the existing p-trap I have and then use the flexible coupler to attach the Ikea pipe to it.

What a pain, of course after I buy the thing I find out so many other people have had the same problem. 2 hour job turned into a complete pain in the arse. I won't be buying an Ikea sink again that's for sure.
