Sink Drain Leaks

  1. For the most part, fixing sink drain leaks requires replacing some or all of the drain pipes under the sink.
  2. Unless the drain pipes are exposed, it is recommended to use plastic drain pieces. When joining tubular plastic pipe be sure the wedge on the nylon washer is facing the hub.
  3. When joining tubular pipe to a steel trap arm it is best to use a metal nut not plastic. Metal on metal, plastic on plastic.
  4. If the sanitary tee in the wall cannot be connected to, replace it with a new one that will work.

Replacing a Strainer or Pop Up Assembly

  1. Remove the old drain piece. Cut it out if you have to.
  2. Use plumber’s putty or silicone on the top drain piece that¬† touches the sink.
  3. Use pipe dope or teflon on the threads under the sink and install the rubber seal.

Replacing the Sink

  1. If the faucet is mounted on the sink install the faucet on the sink before setting the sink. Also install the drain connection to the sink before installing the sink. Use pipe thread sealant on threaded tailpieces
  2. Shut the water off to the sink and disconnect water and drain pipes.
  3. Steel sinks are held down with clamps on the bottom side. Cast iron sinks are simply caulked or tiled right in. Ceramic sinks that sit on the countertop are also held in place with caulk.
  4. Set the new sink in place. Re connect drain and water lines. Put a bead of caulk around the rim of the sink for countertop self rimming sinks.
  5. Test for leaks.

Single Handled Faucet Repair

  • Single handled faucet repair is unique to the make of the faucet. But, with a little courage and investigation it is rather simple.
  1. Always begin faucet repair by shutting off the water supply to the faucet underneath the sink. Open the faucet to relieve any pressure and to assure the water is off.
  2. Remove the handle. Handles are held in place by a screw typically. If there is a cap on the handle to remove, remove it and a screw should be underneath the cap. Sometimes the screw is behind or underneath the handle.
  3. After removing the handle you can remove the cartridge. The cartridge is the guts of the valve. Cartridges are held in place by screws or a large nut or a retainer pin. On some retainer pin types a sleeve must be removed first.
  4. After removing the cartridge is removed you can inspect for damages. On most faucets the cartridge is all that needs replacement. Some faucets require replacement of rubber parts in the valve body itself. Be sure to replace all rubber parts if any.
  5. When replacing the cartridge it is a good idea to lubricate it with a valve lubricant.

Double Handled Faucet Repair

  1. There are generally two types of two handled faucets: The compression type, and the cam type.
  2. When repairing faucets, always start with turning the water off to the faucet.
  3. Remove the handles. Handles are held on by a screw under a cap, or a set screw on the side or underneath the handle. Very rarely a handle is held on by a screw on ring.
  4. After removing the handles, remove the stem or cartridge. Normally this is done by removing a large nut or turning the entire stem.
  5. Replace the stem or cartridge with a new one or install new rubber pieces on the stem.
  6. On compression valves there is a seat inside the valve body which should be replaced at this time. Seats are easily removed with a seat wrench.
  7. Replace all parts, restore water to the faucet and check for leaks.

Handle Leaks

  1. Handle leaks normally occur when the faucet is operated.
  2. Remove the handle.
  3. On most double handle type faucets there is a packing nut sealing the handle shaft. Tighten the packing nut until the handle no longer leaks. Tightening it too tight will make the handle hard to operate.
  4. Other valves are sealed with rubber parts and they should be replaced.

Replacing the Faucet

  1. Always shut off the water to the faucet when working on it.
  2. Remove the supply lines from the faucet end.
  3. Remove the nuts holding the faucet on underneath the countertop.
  4. Sometimes it is necessary to use a basin wrench to remove these nuts.
  5. Remove the old pop-up drain stopper assembly, If necessary, cut it out with a hacksaw or sawzall.
  6. Install the new faucet and pop up drain per manufacturer’s instructions.
  7. Be sure to use Teflon or thread sealant on threads of screw on tailpieces.
  8. Reconnect the water supplies and check for leaks.
