How to Fix a Water Heater Leaking From a Drain Valve in Singapore?

Fixing a water heater leaking from the drain valve in Singapore can easily be done. You only need to follow all the below-given steps to do it like a pro, keeping all the safety protocols in mind. Let’s get to the guide now.

Turn Off The Power Supply

Before anything else, the power has to go. If it’s an electric heater, flip the switch at the circuit breaker. If it’s a gas one, shut off the gas valve. 

You’re not trying to get shocked or risk anything here. Don’t skip it thinking it’ll be fine; it’s not worth the risk. Make sure that thing is completely off before you even think about touching it.

Shut Off The Water Supply

Next, stop the water from flowing into the tank. Look for a valve near the top. Usually, it’s markedly cold. Turn it all the way to the right until it stops. That shuts off the water coming into the heater. 

If you forget this step, you’re going to end up with water spilling everywhere when you open things up. Better to avoid that mess right from the start.

Attach A Hose To The Drain Valve

Go down to the bottom of the heater and find the little valve. It usually looks like a short tap. Grab a garden hose and screw it on there. 

Make sure the other end of the hose leads to a drain or somewhere outside. You really don’t want this water ending up all over the floor. Take a second to double-check the hose connection before going any further.

Drain The Water Heater

Now you’ll let the water out. Open the drain valve slowly. You might hear it sucking air or gurgling at first, totally normal. Let it empty out completely. No shortcuts here. 

If there’s still water inside, it’ll fight you later when you’re trying to fix or swap the valve. Just give it a few minutes and keep an eye on the hose while it drains.

Inspect The Drain Valve

Once the tank’s empty, take a proper look at that valve. Is it cracked? Does it look worn out? Sometimes they just get loose, and that’s enough to cause the leak. 

If it feels tight and still leaks, there’s probably an issue inside it. You don’t need to be a plumber to spot a bad one. If it looks rough or old, it’s probably time for a new one.

Tighten Or Replace The Valve

If it’s loose, tighten it gently using a wrench. Don’t crank it, just firm enough to stop any wiggle. Still leaking? Then yeah, it’s got to go. Unscrew the old one, clean around the threads, and twist on a new one. No need to overdo it. 

Once it’s on, give it a quick check by running some water through it. That’ll show you if the leak’s actually gone.

Refill The Tank And Restore Power

Once the new valve’s in place and tightened, close them. Turn the cold water back on and let the tank fill up. Keep an eye on it. 

You can open a hot water tap in your bathroom, which helps the air escape. Once water starts coming out steadily from the tap, it means the tank’s full. Now, and only now, you can turn the power or gas back on.

Final Words

If you let the water heater leak water, it’ll raise your electricity bills, damage the floor and keep wasting water. So, how to fix a water heater leaking from the drain valve in Singapore? 

First, turn off the power to the heater, then shut off the water supply completely. Attach a hose to the drain valve. Now open it and let the tank empty. 

Once drained, check the valve for cracks or wear, then tighten it if it’s loose or replace it if damaged. Close the valve, turn the water back on, and finally restore the power once everything is dry and steady.
