Water heater leaking? What to do right now

If your water heater is leaking, turn off its power or gas, close the cold-water valve on top of the tank, and keep the water away from belongings. A leak from a fitting can often be repaired, but water from the tank itself usually means replacement. Cornerstone Plumbing in Milford can tell you which: (508) 361-9450.

Why is my water heater leaking from the bottom?

Water at the bottom of a water heater most often comes from a corroded tank, which can't be repaired, but it can also be a loose drain valve or water running down from a fitting or the relief valve above. Cornerstone Plumbing checks where it's really coming from before recommending a repair or a replacement.

Can I still shower if my water heater is leaking?

It's best not to. Using hot water keeps refilling a tank that may be failing, which adds water to the leak. Turn off the power or gas and close the cold supply until a plumber has looked at it. Cornerstone Plumbing can advise on the phone whether it's safe to keep using it.

How much does it cost to fix a leaking water heater?

It depends on what's leaking. Replacing a valve or fitting is a small repair, while a leaking tank means a new water heater, with the permit and code items the installation needs. Cornerstone Plumbing doesn't price jobs sight unseen, but explains the options and gives you a price before any work starts.

How long do water heaters last?

Tank water heaters typically last about 8 to 12 years, depending on water quality, maintenance and the type of heater. A tank that's in that range and starting to leak, rumble or rust is a good candidate for planned replacement before it fails. Cornerstone Plumbing can look at the age and condition.
