P-Trap is a pipe that will connect the waste pipe and the overflow pipe to one main pipe. When it fits perfectly, join them with cement. It is a trial and error process and may need repeated adjustment. Also ensure that the overflow and drain fitting should be facing each other before fastening them to the drain pipe. Make sure the hole in the tub meets the drain fitting. Or use a sanitary tee and cut a pipe that fits from the outlet of tee to the fitting of the drain. It should easily line up to the holes of the bathtub. Now, measure the new bathtub pipe by placing it next to the old pipe. Measure the drain hole from the inside of the tub to the surface the tub rests upon. Remove the bathtub and set the tub down on a hard, balanced surface. Once they are found, detach the drain pipe and over flow trim from the tub with the help of a drain wrench. Now, locate the area where the drain pipes are located. Step 2 – Detachment of the Assembled Partsīefore starting with the detachment of the parts, it is essential that you turn off the water supply from the area. Make sure you meet all local plumbing ode requirements while choosing the pipe. Also, buy a good quality drain pipe since it will last longer. Note down the measurements and use them to purchase the pipe of proper length and diameter. Replace the drain assembly and then fasten the plate with the two mounting screws to finish the job.Take the measurements of the drain pipe and drain hole. Make sure it seats evenly for a complete seal around the connection. The overflow pipe will have a little play (although not much) that should allow you to adjust its position and make room for the gasket. Use a little plumber’s silicone grease to lubricate the gasket and work it into place around the mouth of the overflow body. When installing the gasket, make sure the thick side is at the bottom. You’ll need to buy a new overflow washer or gasket from the hardware store. But since I had already opened the wall, here’s a look at the rear of the overflow body where the old gasket is falling out. With any luck you can complete the repair from the tub without having to open the wall. I used an old wire hanger to dig out the rotted gasket material from the overflow body. Shown here is the old deteriorated gasket that must be removed. Pull out the assembly, including the drain plug. The first step is to remove the screws that mount the cover plate. The good news is that replacing an overflow drain gasket is a fairly easy fix. I only mention this to demonstrate that plumbing leaks can happen in some seemingly unlikely places, and locating the problem can be half the battle. Something about the manner in which my wife showers-whether it’s the way she shampoos her hair or maybe shaves her legs-directs water onto the overflow drain, and consequently past the deteriorated gasket. Finally, as she was showering, I inspected the plumbing from the floor below and followed the active leak all the way up to the overflow drain. ![]() The tub only leaked when my wife took a shower in it. Nor did we have problems when my kids took a bath. Most frustrating of all: I could not reproduce the leak when I took a shower. I eventually opened up the ceiling and the wall behind the faucet to investigate. Convinced of this, I replaced a couple of faucet valves, tightened some threaded connections, and sealed a couple different drain connections with silicone tape, yet I still had a leak. It didn’t make sense to me that the overflow drain got enough water exposure to be the source of a leak which was ruining a drywall ceiling downstairs. You wouldn’t think a bathtub overflow drain would be the source of a water leak, especially if you never fill the tub to a level at which water would enter the opening.
