Guide: How to find a water leak

Water leaks are a very common occurrence in homes and properties – even in newer builds. What’s more, not all leaks are easily discoverable. In fact, some are so well hidden that by the time you’ve found the leak the damage has already been done to your property.

Here at Greenstar we believe that all property owners should be well-equipped to learn if they have a water leak and how to find it. Read on to learn how you can find the water leak in your property before it’s too late.

How can I tell if I have a water leak?

Whilst some leaks are fairly straightforward to work out (for example if a sink breaks and water starts shooting out), most leaks are very difficult to find. Water may even be trickling somewhere within a wall which doesn’t get discovered until there’s severe damage to your property.

We suggest you should look into the following which can help you determine if you have a water leak in your property and how to find it.

You find discolouring or water stains on the ceilings and walls

Discolouration on your ceilings or walls could indicate that water is leaking through. The discolouration is usually yellowish or brownish in colour.

Your paintwork is cracking, peeling or bubbling

Any wet paint (that’s not recently been applied) or detaching wallpaper are strong signs of a water leak behind that wall. What’s worse, any bulges in wallboards indicate that the water damage is more severe and more often than not will require replacing.

You can hear a dripping sound

A fairly self-explanatory suggestion, but one that should be called out nonetheless – hearing a dripping sound can ultimately help you determine the leak’s location.

You find mould or mildew or encounter a musty odour

A long-term water leak creates the perfect humid environment to allow mould to grow. On your wall’s exteriors you may find the mould in the form of black blotches. However, mould often grows inside your walls that you won’t be able to see. Instead, you may experience a musty odour by your walls, which may indicate mould has developed inside your walls as a result of a water leak.

There’s discrepancies in your water bill

Your water bill could be an indicator that you have a water leak, especially if you receive a monthly bill that is unusually higher. Property water usage is typically predictable – for example, the Environment Protection Agency reckon a family of four will use about 12,000 gallons of water per month (and maybe more in the summer). Do note that even a steady dripping faucet can waste around 800 gallons of water monthly, so it’s good practice to monitor your water bill regularly.

There’s discrepancies in your water meter readings

To make absolutely certain that you do indeed have a water leak, we recommend you monitor your home’s water meter. The best way to do this is to:

  1. Turn off all water-using appliances (i.e. dishwashers and washing machines) and water faucets
  2. Locate your water meter and take a note of the numbers
  3. Wait an hour
  4. Check the water reading again
  5. If the numbers have changed, then you have a water leak somewhere

Where is my leak coming from?

We suggest you look into the following to work out where you water leak is coming from.

Check for greener grass

Whilst you may be yearning for a garden consisting of lush, green grass, be aware that a noticeably greener patch of grass could be the result of a buried water line leak. Puddles may even become visible on the ground surface.

Check your appliances and fixtures

Should the water meter indicate that your leak is coming from inside your property, then you’ll need to take the time to diligently explore all appliances and fixtures. These include looking under all the cabinets that are located underneath a sink to ensure they’re dry. Also, you should look for puddles across all your household appliances, like your dishwashers and washing machines etc.

If you find any puddles, we strongly advise you turn off your water supply and get in touch with Greenstar right away.

Check the toilets

It’s also well worth checking that your toilets don’t require repair, as they’re prone to leakage. We recommend using food colouring, putting a few drops in the tank of every toilet in your property. Should you have a toilet leak, colour will appear in the bowl within five minutes. The leak is most likely down to an issue with the toilet’s flapper (i.e. the rubber stopper mechanism which prevents water from entering the bowl until you flush).

If you’re unsure of how to deal with this leak, feel free to get in touch with Greenstar where one of our plumbing specialists will be on hand to help.

Consider installing leak detectors

As some pipes are more likely to leak than others, it may be worth investing in leak detectors. These are ideal for property locations where the older pipes are situated, as well as by water heaters which can develop holes due to water tank corrosion. By detecting a water leak early, you’ll be able to turn off the water supply before the water leak causes considerable damage to your property.
