Leak Troubles? Simple Steps to Stop Appliance Water Damage

If water is pooling around your washing machine, under the sink, or behind the boiler, you’re probably dealing with a leak. Leaks not only waste water but can cause mould, rust and expensive repairs. The good news is many leaks are easy to spot and fix before they become a big problem. Below are the most common places leaks hide and the quickest ways to shut them down.

Where leaks love to hide

Appliances with water connections are the usual suspects. A water heater’s pressure‑relief valve can drip when the valve is worn. Boilers often leak at the pump seal or from the expansion tank. Washing machines may seep from the door gasket, the hose connections, or the pump filter housing. Even a dishwasher can develop a leak at the spray arm or the tub seal.

Check the floor under each appliance for fresh wet spots. If the floor feels damp after a wash cycle, the leak is likely coming from the machine itself rather than the pipework. Look at visible hoses – any cracks, bulges or loose clamps are warning signs. Don’t forget the hidden pipes behind cabinets; a slow drip can go unnoticed for weeks.

How to stop a leak yourself

First, turn off the water supply. Most appliances have a dedicated shut‑off valve nearby; if not, close the main valve for the house. Disconnect the power to avoid any shocks. For a leaky hose, tighten the clamp with a screwdriver or replace the hose if the rubber is cracked. When a door gasket on a washing machine is worn, wipe it clean and apply a thin layer of silicone grease; if the damage is severe, replace the gasket – they’re cheap and fit in minutes.

If the leak is at a valve, use an adjustable wrench to tighten the fitting. If tightening doesn’t help, the valve may need a new washer. Pull the valve apart, swap the old washer for a new one of the same size, and reassemble. For boiler leaks at the pump seal, you’ll usually see a small amount of water around the pump housing. Tighten the pump mounting bolts first. If water still pools, the seal is worn and you’ll need a replacement seal – most plumbers can change it in under an hour.

When dealing with a water heater, the pressure‑relief valve is the main leak point. Lift the valve’s test lever to see if water sprays out; if it does, the valve is working but may need a new seat. Shut the water, let the tank cool, then replace the valve using a pipe wrench. Always reinstall the discharge pipe correctly to avoid future drips.

If you’ve tried these steps and water keeps coming, it’s time to call a professional. A persistent leak could mean a cracked pipe behind the wall or a failing internal component that needs a specialist’s tools.

Remember, catching a leak early saves water, money, and hassle. Keep an eye on the floor under appliances, tighten loose connections, and replace worn parts quickly. With these simple checks, you’ll stop most leaks before they cause real damage.
