Why Your Ceiling May Be Leaking
Here are some common causes of ceiling leaks.
Toilet leaks can come from the water or supply tank, but some of the most dangerous water leaks that may affect ceilings come from the worn wax ring.
Water seeps through the wax ring when you flush and may start running behind the walls, dripping down pipes, and causing water damage on your ceiling. This moistens the drywall, producing wet spots.
Shower leaks may be difficult to detect at first since all of the plumbing is buried in a wall and surrounded by tiles.
Your ceiling leak may be caused by an upstairs shower if the tiles or flooring are peeling or curling near the shower. Worn out caulking or holes in water supply lines may be the culprits.
You may not notice your sink is leaking until there is water pooling on the floor. By that point, the cabinet doors may be damaged and moldy at the bottom. The water leaking from your sink may be coming from:
- The supply hoses
- Damaged caulk
- Loose P-trap connectors
- A loose strainer or a strainer that needs to be replaced
There are many reasons why your roof might be leaking. Some of the most common reasons include:
- Missing or damaged shingles
- Gutter problems
- Ridge caps and valleys
- Vents, skylights, and chimneys
Roof leaks typically cause larger water spots to your ceiling that brown and grow mold quickly if left unchecked. Every time it rains, the spot may get bigger, and water may also run down your walls. You may have to go up onto your roof to assess the problem further so you can see what the leak is being caused by.
Ways to Fix Ceiling Leaks on Your Own
Here are three ways you can fix the common causes of ceiling leaks on your own.
There are two simple ways to fix toilet leaks. The first way is to replace the wax ring, and the second way is to fix the supply tube or leaking shutoff valve.
Here are some steps you can take to fix toilet leaks:
- Drain and remove the toilet.
- Remove the existing wax ring.
- Remove the toilet flange bolts.
- Attach the new wax ring.
- Position and bolt the toilet back to the floor.
- Reconnect the toilet and test the new wax ring.
- Turn off the water supply to your toilet.
- Empty the water from the toilet.
- Loosen the nut connecting the supply line using a wrench.
- Install the new supply line.
- Turn the water back on.
- Check for leaks.
- Shower Leak Repair
For shower leaks behind the wall, here are the steps you need to take to fix it:
- Cut an inspection window to inspect the shower pipes.
- Look for signs of leaking.
- Turn on the shower to find the source of the leak. You may need a flashlight or a mirror for this.
- Fix a leaking shower arm or valve. If the shower arm is the reason for the leaking shower, all you have to do is remove the circular metal plate unscrew the shower arm, clean the joint compound with a wire brush.
Next, wrap the threads with plumbing tape, and screw the arm back into the water pipe joint.
If it’s the valve leaking, you’ll have to turn off the water valve and replace the cartridge. If it is the valve body that is the problem, it is best to call a professional plumber to help you solve the problem.
- Sink Leak Repair
There are two main types of sink leaks that may cause a ceiling leak: water-supply leaks and drain leaks.
Here are some ways to fix sink leaks before they become a major problem:
- If the leak is not already visible, check for the leak by wrapping toilet paper around the supply line.
- If you notice the water coming from the supply line connection, tighten the connection with a wrench.
- If this doesn’t work, turn off the water at the supply valve. Remove the nut and spread plumber’s pipe compound inside the washer fitting and onto the threads. Tighten it down again.
- If the leak persists, you may have to replace the supply line.
- Take out the sink outlet flange and drain pipe.
- Inspect all parts such as the gaskets, rubber sealing, drain pipe, and nut to see if they might be cracked or if the metal or plastic threads are stripped.
- If these items are damaged, you’ll need to replace them and put the parts back together.
- If the sink parts are not damaged, you’ll need to purchase a few items to fix the problem to ensure the leak doesn’t continue. You’ll need plumbers’ tape or plumbers’ putty to make sure the connections are water-tight.
