How to Install a Bathroom Sink Drain P-Trap

The curvy shaped pipe used under the sink is called the drain p trap. It is designed to prevent noxious gases from entering through the pipe. Also, its shape makes it possible to recover dropped items (like wedding rings) that may otherwise be lost in the drain. Follow the simple steps described below to easily install the sink drain p-trap of the bathroom—or to replace a part that you have removed to clear a clog or retrieve a lost item.

Step 1 – Disconnect the Water Supply

Before starting with the installation, disconnect the water supply. This will prevent the hassle of wiping off water from the floor when it drips.

Step 2 – Measure the P-Trap

Measure the diameter of the drainage system and the length of pipe needed. Note it on a piece of paper.

Step 3 – Buy the Right Size

Ensure that you buy the correct p-trap size. Usually the size of the p-trap of a bathroom sink has a standard diameter. Also, select the type you want to use. Two types of p-traps are available in the market a PVC p-trap and metal p-trap. A PVC p-trap comes with complete package that is, nuts and gaskets included. However, the metal p-traps do not come with complete parts. You will have to buy rubber gaskets separately.

In metals, chrome traps do look classy, but they may corrode quickly. The only exception in metal p-traps is that brass p-traps are longer lasting. You should be aware of plumbing code guidelines in your area before you make your purchase.

Step 4 – Test the P-Trap

Check the fitting of the p-trap on the sink before completely installing it. Some adjustments may be needed. If it is longer than needed, cut it with the help of a saw.

Step 5 – Install P-Trap

Now install the p-trap. Since you’ve already made adjustments and sawed off extra length, it should easily fall into place. After p-trap is placed in its right position, slide on the gasket and then place the nut. The nut will be placed on the sink’s tailpiece. Now on the trap’s tailpiece, add a nut and gasket. Once the pieces are placed in position, move toward the thread compound. Place the thread compound on the fraction where the two pipes join together. This action ensures that leakage would not occur. Now nuts and gaskets should be screwed on tightly.

Step 6 – Test P-Trap

Once everything has been placed in their respective place and the p-trap has been connected to the drainage system turn on the water supply. Test the p-trap by running the water through it. This allows you to find out whether there are any leakages or not. Once you are finished, put away your tools.
