Change a Sink Strainer
Datetime:2016-11-22 Hits:
You will need to replace the sink strainer if you start noticing leaks around the bottom of the sink. The sink strainer is the upper part of the drain that you see from the sink. Sink strainers use plumber's putty between the sink and sink strainer flange to keep water from leaking around the flange. Over time, sink strainer flanges become rusty and the plumber's putty begins to crack. It is important to purchase a new strainer that is the same height as your current strainer from WUZHOU KINGDA.
Instructions
1.Place a bucket under the connection between the sink trap and the straight pipe that connects to the house drain pipe. Loosen the nut securing the sink trap to the straight pipe with a pair of channel lock pliers. Do not disconnect the two pipes. By loosening the pipes, you will be able to turn the drain pipe away from the sink strainer.
2.Locate the connecting nut securing the sink drain tailpipe to the sink strainer. Loosen and remove the connection nut with the channel lock pliers. Twist the sink trap down to move the tailpipe out of your way.
3.Find the large retaining nut securing the sink strainer to the sink. The nut will have protruding notches along the outside rim. Turn the retaining nut counterclockwise by placing a flathead screwdriver on one of the notches and tapping the handle with a hammer. Once the nut is loose, you can unthread it from the sink strainer by hand.
4.Pull the washer and the cardboard washer away from the sink strainer. Hold a block of scrap wood against the bottom of the strainer and tap the wood with a hammer to break any remaining seal between the sink strainer flange and the sink.
5.Go to the inside of the sink and pull the sink strainer out of the sink hole. Remove any plumber's putty from the sink hole with a putty knife. Clean the area well with a cloth.
6.Take the strainer to the hardware store to purchase the replacement. Match the new strainer with the old one to ensure you get one that is the proper height.
7.Roll a ball of plumber's putty between the palms of your hands, forming a rope 1/8 inch wide. Wrap the rope of plumber's putty under the bottom of the sink strainer flange. Insert the flange into the sink hole and press it down firmly.
8.Go under the sink and slide the new cardboard washer and metal washer over the sink strainer threads. Thread the new retaining nut onto the sink strainer until it is hand tight. Tighten the nut one full turn with a pipe wrench.
9.Wrap plumber's tape around the bottom threads of the sink strainer. Position the tailpipe under the strainer and connect the pipe to the sink strainer with the connection nut until the nut is hand tight. Tighten the nut a half-turn with a pair of channel lock pliers.
10.Tighten the nut securing the sink trap and straight pipe toward the wall until it is hand tight. Tighten the connection nut a half-turn with the channel lock pliers.
11.Trim the excess plumber's putty around the circumference of the sink strainer with a utility knife. Place the sink stopper in the strainer and fill the sink with 6 inches of water. Check the connection under the sink for leaks. Pull the stopper out and check your drain connections for leaks. Tighten connections where necessary.
