Hot water tank leaking
Water pooling under the tank, rust streaks down the side or water coming from the base almost always means the inner tank has corroded through. It can't be repaired, and it can get worse quickly, so we'll quote a replacement, which can usually be done the same day.
Hot water system leaking from the overflow
The overflow pipe carries water from the pressure and temperature relief valve. A small discharge while heating can be normal. A constant drip or steady flow usually means the relief valve is worn, the water pressure is too high and needs a pressure limiting valve, or the expansion control valve has failed. These are repairs, not replacements.
Leaks from fittings and valves
Leaks at the inlet, outlet, tempering valve or pipe joints are usually a worn valve or fitting, and are repaired on the spot.
Hot water problem right now?
Check these first. They can save you a call-out.
Electric system?
Check the hot water circuit or safety switch at the switchboard hasn't tripped. If it trips again, leave it off.
Gas system?
Check the gas is on at the meter, or that the LPG bottle isn't empty.
Leaking or burst?
Turn off the cold water valve going into the unit, then turn off its power or gas.
Common questions
Is it normal for my hot water system to leak from the overflow?
A small amount of water during heating can be normal. Constant dripping or running water is not, and usually means a worn relief valve or high water pressure.
Can a leaking hot water tank be repaired?
No. If the water is coming from the tank itself, the lining has corroded through and the tank must be replaced. Leaks from valves and fittings can be repaired.
Is a leaking hot water system an emergency?
A tank leak can worsen quickly and cause water damage. Turn off the cold water to the unit and its power or gas, then call. We answer 24/7.
