Putting the finishing touches on that newly installed sink involves hooking it up to the home's plumbing system. Most home are built with PVC as the main piping in the drainage system, so there's often the need to connect metal pipes to the plastic PVC piping. Using the proper-sized PVC threaded fittings, and a flex hose connection kit, will allow you to make the transition from copper to PVC with a leak-free connection.
Things You'll Need
- Measuring tape
- Utility knife
- PVC cement
- 2 male threaded adapters
- Pipe thread tape
- 2 flex hose connection kits
- Adjustable pipe wrench
Turn the water supply off to the PVC pipes at the main water shutoff.
Measure and cut the existing PVC pipes under the sink to fit as needed, using a measuring tape and hacksaw. Clean the end of each cut pipe, using the utility knife to remove any PVC burrs from the cuts. There are two PVC pipes, one for hot and one for cold water, that connect to the faucet.
Apply the PVC cement to the end of each of the existing PVC pipes, and the inside of the slip end (end opposite the threads). Slide the slip end of each fitting over the end of the PVC pipes. Twist each fitting 180 degrees as you insert it on the pipe to evenly distribute the cement and to fully press it onto the end of the pipe. Allow the cement to set for a few minutes.
Wrap the male threaded ends of each PVC fitting and the male ends of each of the existing copper fittings on the faucet with the pipe thread tape. Start at the end of the fitting and wrap the tape up the fitting until all the threads are covered. This will help provide additional sealing for the connections.
Thread one end of each of the two flex hose connections to the copper fittings on the faucet. Insert the female connector on the flex hose over the male connector on copper faucet, and thread the fitting with your fingers clockwise. As the fittings tighten up, use the pipe wrench to further tighten and seal the connection.
Attach the remaining ends of the flex hose to the PVC fittings. Locate the flex hose connected to the labeled hot water side of the faucet and connect it to the threaded male connector on the labeled hot water PVC pipe. Thread the female fitting on the flex hose to the male PVC fitting and tighten it down with the wrench. Repeat this step to connect the cold water hose from the faucet to the cold water PVC threaded fitting.
Turn the main water valve back on, and turn the faucet on to test for water flow. Allow the air to clear out of the water line, and run both the hot and cold water sides until the water flows smoothly. Inspect each connection to ensure there are no leaks, and tighten the fittings additionally to seal any possible leaks.
Tips & Warnings
- Don't allow the PVC cement to touch the skin as it can result in serious irritations or burns.
