plumbing question in a small kitchen remodeling project?

March 25th, 2008 | by admin |
big blue asked:

we want to relocate the sink (to an island which is 3 -4 feet away from it’s original location) … Is’t possible to extend the existing plumbing/pipe without re-routing the plumbing (which would cost more than $10,000 from what I have heard as the basement below is finsihed).

      Maybe. You must be able to maintain enough downward slope in the extension so that the water will drain properly. This isn’t much for a 4′ run (about 1/8″ drop), so that may not be an issue.

      Another problem is venting. Normally, a sink is drain would be vented up the wall and connected in the vent stack in the attic. Since there is no wall going up to the ceiling for an island, it has to be done a bit differently. The best venting solution for an island is called a “Chicago loop”. A picture is worth 1000 words, so have a look at the picture on the wikipedia page)

      Getting the proper venting may be more of a problem with your extension than the actual waste line.

      Another option would be to use an air admittance valve to handle the venting, but results certainly vary with this option. Some have good luck with them, I have replaced a few so I try to avoid them at all costs. Use your judgement.

      You have to get the drain connection below floor level so the drain from the sink works. Also, the new drain has to run under the floor and that would be tough to do unless you cut out flooring.
      People ask me why I recommend to put suspended ceiling in the basement. Here is a perfect example. A few tiles out, job done without wrecking anything.

      Good luck.

      Ahrg. Whoever gave you this 10k guesstimate was either drunk, lying, a criminal or ALL THREE. Geeze. Honestly, $600 for a really slow plumbers work (and materials) and another $500 for a carpenter to patch the basement ceiling should do it. Unless you have platinum pipes and a sterling silver ceiling in your basement…..1500 bucks TOPS.

      Keep getting estimates until you find honest contractors to do this work.

      If you have been quoted so much, then it is a serious problem, even a rip off wouldnt quote so much unless it was a major task!

      yes but you would have to get more pipe to route it over to the island.
