How to disconnect the pipes by taking the bathroom sink and the vanity off

August 14, 2019Uncategorized Standard

Removing a bathroom vanity can be a formidable job, especially if it has tile or otherwise built in. The first step in the demolition — removing the pipes — is the least complicated. If the vanity has a sink or two, disconnecting the water supply and drainage pipes is simple. If you’re going to replace the vanity with a new one, you can let the plumbing pipes stumble out of the wall, but if not, it’s not hard to cover the lid behind the wall and cover more.

Instructions

  1. Turn off the angle stops under the vanity. The two shut-off valves protrude from the wall connected to the hot and cold water supply lines. Open the tap and let the water drain out.
  2. Remove the supply pipes from the faucet from the angle stops by pulling out the connectors with the pliers from the slip lock. Unscrew the other ends of the pipes from the tap stems in the same way and remove the supply pipes.
  3. Unscrew the compression nut at the end of the drain, which is the tube stuck under the drain and exit the trap. Sometimes you can loosen this nut with your hand, but if you cannot, use slip lock pliers. Unscrew the compression nut on the end of the drain tube protruding from the wall and remove the trap. Keep the trap vertical so as not to spill the water out, take it out from under the sink.
  4. Things a rag in the outlet drain if you plan to use again. The rag will block sewer gases.
  5. Cut the drywall in the drain and water pipes with a VI plaster if you want to cover the pipes and hide behind the wall. Remove a rectangular piece, instead of one with an irregular shape, so it will be easier to replace when you finish with the tubes.
  6. Cut the drain outlet with a hand saw so that the opening is behind the wall. Leave at least one inch of the tube protruding from the lining and stick to ABS or black plastic cover, with ABS cement.
  7. Close the shut-off valve that controls the supply lines of the faucet. Open the angle stops and collect the water that drains out into a bucket. Cut the copper pipes so that the angle stops are joined behind the wall with a pipe cutter again leaving at least an inch of pipe protruding from the splices.
  8. Spread the flow at the ends of the pipes and inside of two copper lids, slide the plugs into the pipes and solder them in with lead-free solder. When the solder cools, open the water and check for leaks.
