How To Attach the P-Trap to a Sink

A p-trap is the curvy shaped tube that we see under the sink. A p-trap is essential in every home installation that has the ability to drain water. Some of these include sinks, bathtubs, showers and washing machines. The p-trap is made of three essential parts. These are namely the curved trap piece, a tailpiece and a drain elbow.

When you use the bathtub, the toilet, or wash your hands, the water that drains down the tube will not stay there for a long time. Because of this, the wastes that go down the drain are not fully eliminated. When these human wastes decompose, they give off fumes, such as methane. The p-trap’s purpose is to prevent toxic fumes from venting out in your home. It traps these fumes into the plumbing system. It can do this with the p-shaped tube. When the drainage is used, a little amount of water stays on the curved portion of the p-trap. The water that remains on the p-trap acts as a barrier for the gasses that are not eliminated. When you run the faucet again, the water gets replaced.

Of course, the p-trap can get clogged with continued use. Also, a lot of people lose their jewelry in the p-trap. Once you have removed the p-trap system, it may be hard for you to install it back on your sink. Here are the simple steps on how you can attach the p-trap to your sink:

  1. Materials. First, gather all the materials that you will need. They are the p-trap, channel lock pliers, a saw, rubber gaskets and pipe thread compound. You can find all of these in your local hardware or plumbing store. Make sure that you get the right size of p-trap for your bathroom sink. The standard measurement of the pipe should be 1-½ inches from the trap. There are two types of p-traps that you can purchase. The first one is the PVC trap and the other one is the chrome trap. If you are using a chrome trap, you also have to get rubber gaskets. For the PVC, all the nuts and gaskets already come with the p-trap set.
  2. Test the pipes. Before fully installing the p-trap, you have to test it first on your sink. Try to fit the p-trap on the sink. For this, you might need to make some adjustments. If the p-trap is too long, you can saw off a portion of the pipe.
  3. Attach the p-trap. If the pipes are already fit to size, slip the gasket and the nut on the tailpiece of the sink. After this, slip in the nut and gasket through the trap’s tailpiece. Assemble the pieces together and be ready with the pipe thread compound. Once the pipes are set, put some pipe thread compound on the parts where the pipes meet. This will ensure that there will be no leaks on your sink. Tighten the nuts and gaskets.
  4. Test the p-trap. When you have connected everything and the drain system is in place, the last thing you have to check is if there are no leaks. To do this, fill the sink with water and look under your sink if there are any leaks visible.

These are the steps on how you can attach a p-trap to your sink. Now, it will be easy for you to do this when you have to retrieve lost jewelry or if you need to replace your drainage system for your sink.
