Tips For Plumbing Leak Detection

Posted on: 2 May 2018

Leaks may appear to be a small problem, but left unattended they can cause serious damage. That leaky faucet could translate into gallons of lost water and high water bills. Leaks can damage your ceiling, form cracks on walls, cause pipes to rust, and threaten the overall structure of your home.

Here are a few tips on how to detect leaks.

Leaky Faucets

The most obvious sign of a leak is a faucet that won't turn off completely. After turning it off, you'll still see water dripping.

Check the Ceiling

Look out for damp spots, watermarks, and stains on the ceiling. This signs could mean there's a leak through the roof. Or, if the indicators appear on the ceiling of a lower floor, a bathtub leaking is a likely culprit. Bathtub refinishing is a must to seal any cracks in the tub and stem the flow of water. Otherwise, mold and rot can build up in the flooring and ceiling materials. Floor collapse is a late-stage possibility. Contact a bathtub refinishing company like Carefree Koatings to take care of the problem. 


Are your walls cracked? Is the plaster bulging out or peeling off? You most likely have a leak inside your wall.


The presence of mold in your home is another indication of a possible leak. Pay special attention to your basement, but also check the floor, roof, and walls.


The sound of running water when all faucets are turned off is a sign of a leak, most likely in your slab's foundation.

Low Water Pressure

There are many reasons for low water pressure but one of them is leaks. A leak anywhere along your supply pipes or inside your home can cause your water pressure to drop.

Dye Test

A leaky toilet may not be obvious as the water runs directly into the sewer. To find out if you have a leak in your toilet, turn off all faucets in your home. Put a dye tablet in the cistern and wait a few minutes. Check the toilet bowl. If you see signs of the dye, your toilet is leaking.

Check your Water Meter

Some water leaks can be detected visually. Others are more hidden. You could actually be experiencing a leak without your knowledge. If you've been getting unusually high water bills, you may be a victim of a leak.

Turn off all your fixtures and appliances that use water. Go to your water meter and take the reading. Also note the time. Come back after 30 minutes and check the meter reading. If the needle has moved, it means you have a leak.

Sometimes obvious signs of water make leak detection easy, but you could also have a leak somewhere in your house and not see any physical indication. Visible signs of leaks include mold, dampness in the structure of the house, and dripping faucets.

For less obvious leaks, you'll have to check your meter and inspect your toilet bowl. If you detect or suspect a leak in your home, get your neighborhood plumbers to assist.
