How to Check For Leaks in a Bathroom

Domestic bathroom with sink and toilet

The bathroom is where you would usually find leaks in your home. Water stains on the ceiling of the room below are an obvious sign of leaks in your bathroom. Leaks often occur in plumbing fixtures such as sinks and toilets. Unsure on how to check for leaks in a bathroom? We have the expert industry knowledge on how to check for leaks in a bathroom. These top tips could save you from a repair bill on your plumbing.

How to check for Shower Leaks

The shower is a common culprit for bathroom leaks. The seal of a shower is used to ensure that water does not escape from your shower and cause damage. This is why you should check the seal regularly to make sure it is working properly. If your shower seal is damaged and goes unnoticed, it could lead to serious water damage and plumbing issues. Water damage to the surrounding walls and floors could lead to a large amount of repair work. A common sign of water damage from your shower is peeling paintwork, mould spots or rotten flooring.

Here are some great ways of preventing damage from your shower:

  • Ensure that your shower curtain is not letting out water by closing it fully or using a splash guard
  • If you have shower doors, make sure they are properly closed
  • Fill any gaps in your seal with caulk and check this has sorted the leak

Check for Tile Leaks

Damaged grouting on your tiles allows water to escape past the tiles. This allows water behind your walls or onto the floor, causing water damage. If you notice any mould on your tiles, it is likely that you have tile leaks. You may want to consider re-grouting your tiles to ensure this doesn’t happen.

How to Check for Toilet Leaks

Leaks often occur from a toilet every time it is flushed. This is caused by a leak between the waste pipe and the actual toilet. One obvious sign that your toilet is damaged is if it moves when you sit on it. This shows that the seal is loose and broken. Check the seals around the bottom of your toilet and make sure the toilet is secured to your bathroom floor.

How to Check For Bathtub Leaks

Bathtub leaks are similar to shower leaks. If a seal on a bathtub is faulty, it will often lead to water damage and plumbing damage if it is not noticed quickly. Simply fill the gaps in your seal with caulk and check the seal is working properly. Leaks from the pipes, however, can be harder to spot. This is due to the fact that the pipes are hidden by bathtub panelling. Water stains on the ceiling from the room below are an obvious sign that your pipes are faulty. If you are unsure about a leak from a pipe, feel free to contact us or see if you are in need of our drainage services. Leaks around the plugs are another place where a leak can form. These leaks usually leak slowly. To test if your bathtub is leaking, put the bath plug in and fill it with some water. If the water level drops, you probably have a leak. A water leak from the plug will drip on the floor and cause water damage, which could become a serious issue.

Checking for Sink Leaks

Sink leaks usually occur at the joints of the pipes. Water runs down the pipes and on to the floor. This causes water damage to the floor. Frequently check that your sink is not doing this to avoid large amounts of plumbing repair. If you find your sink pipes are leaking, it is a good idea to get professional help.
