Plastic sink drain leaking: Common Causes

Sink drain leaks can be very frustrating, especially when you don’t have some plumbing experience. Other than that, they cause a lot of water damage. Check out these common causes of these leaks.

Advanced corrosion

Rust can erode your pipes and create seep through cracks. Older pipes are likely to have this problem, and replacement is the only solution.

Loose water supply connection

If the leak is constant, the issue could be with the sink’s water supply line. Replacing the line’s gasket or tightening the connection should solve this problem.

Untreated clogs

Clogged pipes will eventually leak. A bathroom clog cleaner can take care of this issue. You can also use the best and safest drain cleaner alternatives such as baking soda. If the problem persists, a drain cleaning service is best for drain clogs.

Worn-out washers

Each time you use a faucet, the washer presses against the valve seat, which will result in wear and tear. Sinks leaks from this can be fixed by replacing the washer, which is also best for slow drains.

Corroded valve seat

The valve seat serves as the connection between the faucet and spout to enhance compression. Accumulated water at the valve seat corrodes it causing leakage around the spout. Calling in a plumber to clean this part is highly advised.

How to Fix a Leaky Plastic Sink Drain Pipe
Prior to beginning with the solution of a leaky pipe, you should try to find the main culprit from the sink drain. First of all, you need to see that either your p-trap pipe is leaked or J trap. If you see that all pipes connected with each other have leakage problems, then do not take time to replace them. If you think that replacement is causing you more cost then opt for repairing the pipes.

Here are some tips:

1. Put the bucket before the leaky pipe and wear your vinyl gloves for protection of your hands from the drain water containment. Turn off all the water valves and remove the leaky pipes.

2. Get the replaced pipes and put them in order to see how they fit with each other.

3. Start from top to bottom and remove the tailpipe nut by forcing it counterclockwise.

4. Remove the large nut securing P-trap via forcing it counterclockwise.  Use channel lock pliers to remove the nuts.

5. Remove the pipe that goes in the waste lines.

6. After completely removing all the pipes, place new pipes along with new nuts.

7.  The process of placement should be as similar to removing them. Tight the nuts and check the water after completely fixing and setting the pipes.
