How To Stop Shower Leaking Through Ceiling

Before you decide on the kind of plumbing repairs you need, you need to zero in on the source of the water leak. Water leaks are often not easy to diagnose. However, because the leak is directly below the bathroom, that should give you a good idea of where to start. The first and the easiest thing to do is look around your bathroom. The cause won’t be apparent immediately, so here are likely causes you should look out for:

1. Leaking Water Pipe

Loose or broken pipes are a very common cause of water leaks. If possible, inspect the water valve that’s behind the walls. If water is dripping or if the connecting pipes are damaged, that’s likely the source of the leak. The source of the leak might also be the water supply lines that connect to the toilet or sink trap. Leaks may also emanate from water seeping through the connector joints in the water supply lines. If this is the cause, you’ll need the help of a plumber who’ll have to tear up part of the bathroom floor to get to the leak.

2. Damaged Bathroom Tile

Bathroom tiles serve an aesthetic purpose, but importantly, they keep water from soaking the bathroom floor and the surrounding walls. If your bathroom tiling is damaged or loose, water can seep into the surface below. Another cause of leaking could be worn-out grout and old substrate (the surface into which tiles are attached).

3. Leaking Drain Gasket

The rubber gasket that’s under the shower drain can, over time, dry out, break, and leak.

4. Faulty Shower Faucet



If your shower faucet drips even after you’ve turned it off, you could be losing a massive amount of water weekly. And, even worse, the dripping can lead to leaks in the wall. Broken gaskets and O-rings are usually the culprits.

5. Clogged Shower Drain

When soap, hair, and any other debris accumulate in the shower drain, it can cause a blockage. If the pan or tub overflows due to the obstruction, water can leak to the surface below.

6. Your Toilet Has A Broken Wax Ring

Another source of water leaks may be the toilet. If a toilet isn’t properly sealed at the base, or if the sealing is cracked, broken, or worn out, toilet water may seep into your walls and ceiling with every flush. To figure out if this is the source, you should flush water that has food coloring. If you find out that this is the problem, you should then shut the water off until the issue is fixed.

It can save you thousands of dollars in further damage. Besides, your insurer may reluctant to compensate you the full amount if they find out that the damage happened gradually, over time.
