P-traps are designed to connect the sink drain hole to the PVC sewer pipe coming from the wall. Though P-traps can be made of PVC or ABS plastic, chrome-plated traps are used as they are more aesthetically pleasing when the sewer pipe is in view. The trap has a bend that holds water which stops sewer gasses traveling up the pipe and back into the bathroom. The trap itself has the section with the bend and a straight horizontal pipe that runs into the vertical PVC sewer pipe coming from the wall.
Unthread and then remove the nut on the end of the chrome trap's bend by hand. Also pull off the plastic compression washer. Push the nut up onto the vertical PVC pipe running down from the sink's drain hole. Then push the compression washer also up onto the pipe. Loosen the nut holding the trap's bent section to its straight section, by hand.
Push the end of the chrome trap's straight pipe into the trap adaptor which is connected to the PVC sewer pipe coming out of the wall. Then push the other end of the trap up onto the vertical pipe running down from the sink's drain hole. Turn the trap adaptor's nut by hand to tighten it to the P-trap.
Tighten the nut around the vertical pipe from the sink's drain hole, to the other end of the chrome P-trap, by hand. Tighten the nut connecting the trap's bend to its straight horizontal section, by hand.
Tips & Warnings
- All nuts should not have to be tightened in place with pipe wrenches, but only by hand.
