Bathroom sink drain connections ?

| Posted in Construction Techniques on December 6, 2002 03:11am

I’m trimming out my two new bathroom sinks and have roughed-in copper drain pipes from the wall with 1 5/8″ outside diameters, 1 1/2″ I.D. The P-trap pipe connects to a 1 1/2″ OD chromed tube, which slides into the copper and is secured with a compression fitting, near as I can tell.

My question is, the chrome escutcheon’s inside diameter is 1 1/2, not 1 5/8, so I guess it doesn’t go around the copper. So am I to cut the copper back to the vanity back and slip the escutcheon over the chrome pipe but not the copper? If so, how would I get the compression fitting, from the chrome to copper, in behind it?  And is it OK to cut the copper drain line with a hacksaw blade to get that far back?

Any ideas? Thanks!

Rob

    Rob,

    You can purchase escutcheons from a plumbing supply house that open and close around finished work.  If the size you need is larger than what you can buy, a file works fine.!  Plumbers are rather costly and not the reason you came to this site...

    Good Luck.

      Ken..if the right sized 'scushy is the problem stumping him right off the bat.....

      I'm thinking the rest of the plumbing might lead to more trouble than it'd cost to hire a guy and get it done fast and right.

      That's all. No harm meant.

        WAITE ??? Jeff, something behind this spelling?

        Jeff,

        You are probably correct with your assumption... But, we all started out someplace along the same road.... Everyone has to dig to get to the bottom of the hole !  So... Give in and give of your expertise...... Hey, it's holiday time.... everyone is entitled to start a leak...

          You guys are both right.  I'm a former carpenter by trade and have deliberately stayed away from plumbing and electrical for fear of drowning and being electrocuted, but now I'm becoming a plumber, at least as far as trimming out my own bathroom!

          Actually, last night, I got the toilet working with no leaks anywhere, after agonizing because the flange was set too low for a standard wax ring.  I got an ultraseal drain connector, and it works great.  Then I connected the sink ptraps (2) to the wall, taking the scenic route cuz the rough in plumber put the drain lines in the wrong spots.  Everything's dry but the connection into the wall drain, and I just got a couple of rubber connectors that should fix that.

          As you say, Ken, I was tempted to call the plumber, but I'd rather figure all this out myself, save some $$, and make a few trips to the Depot for parts rather than call the plumber back and have him smile at me like a dipstick for not doing this stuff myself.

          If all this works, I may just blow off the escutcheons and not push my luck!

            Maybe I should start another thread on this, but as an aside Rob, I'm having trouble with a Kohler toilet leaking at the flange. Tried extra large wax ring, works for a few months, then water under the bowl. Last time I was at HD, I noticed for sale something other than a wax ring for handling the flange-to-toilet seal, and wonder if that's what the ultraseal is.

            TIA,

            Ron

            The thing you saw at the Depot is a knock off of the Ultraseal: http://hsionline.com/products/jsweave/item6439.htm.   I actually used the Depot's version as well because I couldn't find a local retailer that carried the Ultraseal, but the concept is the same for both products.  I'm no plumber, but this looks like a cleaner, more secure connection. 

            The only drawback I can think of is that it narrows the drain line for a few inches, but no more than the horn of the toilet, so I don't think it should present a problem.  I'm curious to see what real plumbers think of these things, besides the fact that they're not traditional, and if they have any failings.

          ok ..the "hinged" escushions are sized to fit just like the others.....'cept they hinge open to fit around existing work.....so unless they are made to fit a larger pipe.....that won't fix the problem...remember.....ya still gotta snap them shut to look good.

          Truth be told...I got lost on the road map of the plumbing description.....maybe cut back the odd sized stuff to inside the wall...and have the new stuff sticking out....

          then the normal 'scuchy's will work...all at the cost of a drywall/plaster patch?

          Jeff

          don't ya think the "E" gives like an old world effect???

          old world.......like in before there were plumbing codes, and such??......Buck Construction   Pittsburgh,PA
