Changing the drain in a utility tub can be a tiring procedure, but if you don't properly replace the tub drain, you can find yourself having problems with leaks, poor water drainage, or even completely blocked pipes. This problem can be solved by replacing the old utility tub drain with a new one. These can be bought from local hardware stores, or even on the Internet. Fitting the new one should not be terribly difficult; if you have basic home improvement skills, you shouldn't need the assistance of a professional. These simple guidelines will help you get the job done quickly and easily.
Step 1: Remove the Old Drain
The first step is to take off the old drain. Turn your water off completely at the mains to ensure that no water enters the system by accident. Then, remove anything from below your sink, such as cleaning fluids and washing up liquids, and put your arms into the space. Leading down from the drain, you will feel a large pipe. Using your spanner, remove this pipe by unscrewing the nut at the top of the connection. You should then see the drain pan and the filter. You will need to unscrew the filter from its position, and then take the drain cord from around the edge (this is a metal strip with a bolt at one end). Unscrew this, and you should be able to lift the drain away from the sink.
Step 2: Install the New Sink
Next you will have to install the new sink. This can be done fairly easily by unscrewing all of the pieces, and placing them in their separate positions. Screw in the drain pan first, using a new drain cord to tighten the pan onto the lip of the sink. Make sure that these two pieces are tightly connected. You should then use your screwdriver to screw the filter into place.
Step 3: Refit the Pipes
Once that is completed, you will have to replace the pipes you took away in the first step. Place the bottom of the pipe in first and then push it into the top of the filter. Tighten the bolts again, so that it is sealed. You may need to add some caulking around the outside to secure any joins.
Step 4: Finishing
Before you finish the project you will have to turn the water back on, and make sure that the drain is working properly. Check your connections for signs of leakage as the water drains away. Once you are satisfied that it is all fitted together correctly, you can replace your utilities under the sink, and use the drain as before.
