How to Install a Bathtub Drain and Trap?

If you are looking for instructions on how to install a bathtub drain and trap, you’ve come to the right place. In this article, we will discuss the P-Trap installation, silicone caulk, and how to get access to the overflow tube. We will also cover the removal of the old gasket.

Installation of a P-Trap 

To install a P-Trap in a tub, first, connect the waste drain and tub drain. Typically, you will need a one-inch PVC female threaded adapter. Next, cut a four-inch nipple from PVC pipe with a hacksaw or file. It is important to make sure the edges are deburred. Finally, connect the waste pipe to the tub drain fitting with a slip joint nut. 

Getting the right P-Trap for your bathtub drain is not as hard as you might think. It is similar to the installation of p-traps in other sinks. Once you have purchased your p-trap, you need to match the diameter of your bathtub drain to the pipe size of the p-trap. 

Gasket removal 

If you haven’t replaced your bathtub drain and trap in a while, you can remove the existing gasket and install a new one. Make sure that the flange is clean and dry since it will seal better if it is clean. Then, place the new gasket around the overflow opening of the trap. Turn the gasket gently to create a seal with the tub. 

To remove the old gasket, first, unscrew the drain flange. This can be done easily with a drain key, which you can buy inexpensively from most DIY stores. Next, scrape off any plumber’s putty on the drain flange. You may need to apply rubbing alcohol if the putty is stubborn. 

Using silicone caulk 

To install a bathtub drain and trap, you need to follow a few steps. First, you should clean out the bathtub. This will ensure that you do not get mold or rust. Then, you need to apply silicone caulk on the exposed parts of the drain pipe. The caulk should form a waterproof seal. The caulk should be applied at a thickness of 1/4 inch. 

Next, make sure you have a caulk gun. A silicone caulk gun is a good tool to use for this job. Its flexible consistency makes it easy to fill in cracks. It will also dry hard and won’t crack over time. If you aren’t sure if silicone is right for your project, you can try using a plumber’s putty. It is less expensive and is available in large quantities. 

Getting access to the overflow tube 

When installing a bathtub drain and trap, the overflow tube must be accessible. This tube is located under the spout and sucks out water when the waterline becomes too high. This tube keeps the bathwater from overflowing and prevents sewer gasses from entering the home. In addition, it is important to install a P-Trap to prevent sewer gasses from getting into the home. 

A trip-lever actuator uses multiple rods that are fitted in the overflow pipe. These rods are not easy to fit on site. When you raise the lever, the rods inside the overflow pipe turn and pull the plunger down. This prevents the overflow from escaping and blocks the drain. 

Using plumber’s putty 

Plumbing putty is a relatively easy DIY project. It comes in small plastic tubs and can be stored in a tool bag. It is easy to roll out a rope of putty, drape it over the plumbing fixture, and push it down firmly into place. When putting the putty into place, you should apply light pressure, not too much, as too much pressure can cause it to dry out and crack. 

One of the disadvantages of using silicone is its odor, which can last for two to three days. Many people compare the odor of silicone to old vinegar. While silicone smells unpleasant, it can be very light and easy to work with. The good news is that you can easily reapply the putty if necessary, allowing you to fine-tune the installation to your satisfaction.
