Installing the drain trap again is one solution to handling plumbing leaks. Also, when you change your bathroom’s sink, you will have to install the drain pipes and trap once more. Usually, PVC pipes are used for the drain, but chrome is preferred if the pipes are not hidden, as it looks attractive. For both types of pipes, the only difference lies in the type of washers that are used for connection. Otherwise, you just need to follow the 12 steps described below.

Step 1 – Purchase Drain Trap

Purchase the appropriate sink stopper and drain trap. If the plumbing comes out of wall you will need to buy a P-trap, which is the most common trap these days. S-trap is now outdated because when water siphons off, it loses its seal. This leads to the rise of sewer gases.

Step 2 – Apply the Putty

Roll the putty into the shape of a snake and apply it around the inner circle of drain flange. Now, insert the flange inside the hole in the sink.

Step 3 – Slide on Gasket

Slide on a gasket and a nut and then tighten it to hold the stopper in place. Use screwdrivers to tighten it.

Step 4 – Hold Assembly in Place

While you tighten the nut, it would be good if another person holds the upper section of assembly. Also, tighten the nut first by hand and then use the pliers to fasten it further.

Step 5 – Put in the Tailpiece

If the stopper of the assembly uses linkage to raise the tailpiece, you will need to put an additional piece on the pipe before inserting the tailpiece. The opening of linkage should point towards the wall when you put in the tailpiece.

Step 6 – Check for Additional Pipe

You might need an additional pipe for the P-trap to properly fit in. Check by holding the P-trap and tailpiece in place.

Step 7 – Fit Tailpiece and P-trap

Now hold the P-trap at the level of the tailpiece. There should be enough spare pipe length in the tailpiece to tighten after it is fitted into the P-trap, as well as wall pipe.

Step 8 – Tighten Female Adapter

Now, tighten the female adapter on the drain stub that comes from the wall. First, slide the nut onto the tailpiece and then the plastic compression nut. Put a nut on the P-trap’s other end, which fits into wall.

Step 9 – Fit P-trap and Tailpiece into Adapter

Insert the P-trap from one end and the tailpiece from the other into the female adapter.

Step 10 – Tighten the Nuts

Tighten the end going in the wall with your hand. Repeat this for the nut on the tailpiece as well. Tighten it firmly, but do not over-tighten.

Step 11 – Connections at the Faucet

Put a clip around the slotted piece from the faucet. Then, insert the rod through the left hole into clip and slot the clip’s right side.

Step 12 – Check for Leaks

The installation is complete. If there is any leaks, loosen and re-tighten the corresponding area.
