Leaking Bathroom Sink Drain: Fix It Quick
Leaking bathroom sink drain is a simple DIY project and one where you can save a lot of money by doing it yourself instead of calling a plumber. When it comes to fixing it quickly, it’s important to understand the pipe size. In most cases for older homes with the bathroom sink drains, they’re connected to a 1 1/4 inch tailpiece and modern homes all use a standard size 1 1/2 inch outlet.
An easy way to determine what size pipe you have is to take a section out and measure the diameter of the pipe. All of the pipes under a bathroom sink look like horizontal extensions. The 90-degree elbows or the P-trap assembly have a diameter of 1 1/4 or 1 1/2 inches. Knowing the size of your bathroom sink drain pipe will help when you’re going to the local home improvement store to get your parts.
Leaking Bathroom Sink Drain: Common Problems
The most common problem with a leaking bathroom sink drain is where the two pipes connect. If you see water leaking where two pipes connect you’re in luck, this is a quick fix. You will need to replace the washer and slip nut because the washer tends to wear out over time.
Identify the diameter of the pipe you’re working with and go to your local home improvement store to buy the replacement slip nut and it’s washer assembly.
Slide the slip nut on the drainpipe with the threads facing the threads on the pipe it will connect to.
Making sure the thicker part of the washer is facing the slip nut, slide the washer on the pipe that has the slip nut on it.
Connect the pipe with the washer and slip nut to the other pipe it connects to.
With the tapered end of the washer going in between the gap of the two pipes, push the washer into the gap.
If you have brass or steel drain pipes, use plumber’s tape on the threads before you connect them. Plastic PVC pipes do not require plumber’s tape.
Start screwing the slip nut on the threads of the other pipe you’re connecting it to until it’s hand tight. Then use a pipe wrench for brass or steel drain lines to tighten the slip nut. Do not use a pipe wrench on plastic PVC slip nuts because you can crack the slip nut. Hand tight pressure for plastic PVC drain pipes is perfect.
Leaking bathroom sink drain: In most cases you can fix
In most cases you can fix a leaking bathroom sink drain quickly and for under 10 dollars. About 90 percent of all leaks in a bathroom sink drain pipe will be from a worn-out washer. Plumber’s tape for PVC drain pipes over the threads can help for a temporary fix however, it won’t last long and should be replaced with a new slip nut and washer.
