You still haven’t figured out the source of the water leak on your ceiling. Is there an easy way to do that? Probably. Find a water leak in your wall with the help of a few of our easy to follow tips.

Shower Door

If you have a shower door, splash water all around the door and frame. Leaks around the frame may take five minutes or longer to show up. If the door has rubber gaskets or rubber sweeps, make sure to check them for gaps. Also, check the caulk for gaps where the shower tub meets the flooring. 



If you start noticing water stains on the ceiling or joists below, or loose flooring near the tubs, damp flooring near adjoining rooms, plug the drain with a test plug and add water. Check, after an hour, to see if the water level has dropped. If you can see the underside of the drain through an access panel or open ceiling, partially fill the tub and then release the water. In a shower, plug the drain with a rag and then release the water. Check the drains and traps for leaks from below through the access panel. If you don’t have access to the underside of the drain, plug the drain and add enough water to form a small puddle around the drain. Mark the edge of the puddle by setting a bottle of shampoo next to it. Then wait an hour. If the puddle shrinks, the drain is leaking. 

Tile Leaks (Tub and Shower)

Tile leaks occur when water seeps through deteriorating grout or caulk and gets into the wall behind the tile. If you see loose tiles or persistent mold, examine the grout or caulk joints for gaps. You will almost always find mold there. If you have loose tile behind the tub spout or faucet, open the access panel behind the faucet and look for dampness or stains. 

Toilet Flange Leaks

If you see water seeping out around the base of the toilet, or loose or damaged flooring or stains on the ceiling below, it is possible that the pipe which meets your toilet from below is leaking. Measure the distance from stacked walls before you go through the hassle of removing the toilet. If the stain is near the toilet, a leaking flange is the most likely source. Remove the toilet and look for the following sources: 

  1. The flange level with or below the surface
  2. If there are any cracks in the flange
  3. Whether the bolts or slots they fit into are broken
  4. The flange is loose not screwed solidly to the floor

Sink Rim Leaks

These kind of leaks allow water to seep under the rim of the base or faucet. If you have a plastic laminate countertop, examine its underside using a flashlight. Look for a swollen particle board or other signs of water damage. You could also dribble water around the sink rim and look for leaks. 

​Make sure to contact a professional plumbing service once you have found out the root cause of the leaks. If you can fix it yourself, then there’s nothing like it. Be sure to check for water leaks regularly.
