My Water Heater is Leaking from the Bottom

You head to the basement to find some wrapping paper and instead you find a puddle of water below your water heater. It seems that your water heater is leaking from the bottom. What could be the cause and what should you do?

First, take a look and try to pinpoint where the leak is coming from. Check to see if the leak is coming from the drain valve. The drain valve is the spigot located on the bottom of your water heater. It is used to drain the sediment from your water heater.


There is a leak coming from the drain valve.

This is a best-case scenario. The seal on the valve could be bad. If this seal is not air tight, it will leak water out of the sides of the drain valve. It could also leak from the valve simply because the valve has gone bad.

This is an easy fix. Call Godby and have us send out one of our plumbers to check the valve and replace it.

If the leak is not coming from the drain valve, it could be coming from the temperature and pressure release valve. This valve is located either near the top of your water heater or on the side. This valve has a discharge tube attached to it that runs from the valve to the floor.


There is moisture leaking out of the discharge tube that is connected to the temperature and pressure release valve.

If you think that the puddle is being caused by this discharge tube, check inside of it and see if there is moisture in the tube. If there is, call Godby and have a plumber come out. You either have a faulty valve or there is too much pressure in your tank. Godby can either replace the valve or adjust the pressure that is coming from the tank.

If neither of these two scenarios seem to fit your problem, then it is likely that your tank is leaking.


I think my water heater tank is leaking.

Uh oh, your tank is leaking. This is the worst-case scenario. If your tank is leaking, it will likely need to be replaced. Sediment, which consists of naturally occurring minerals, has built up in your tank. The sediment has probably corroded your water heater tank’s inner lining. You need to be prepared to have this water heater replaced. Call Godby for help. We will have a plumber assess the problem. If you do need to replace the tank, our plumbers can give you suggestions on what type of water heater would be best for your home and family’s needs.

Once you have located where the leak is coming from, you will need to turn off your water heater. If you have an electric water heater, find the circuit for it and flip it off. If you have a gas water heater, find the on/off switch or dial located on your water heater and turn it off. Once your water heater is off, you will now need to turn off the cold water supply that is coming into your water heater. This is usually a lever/dial and is located above your water heater. You will need to either pull the lever or turn the dial clockwise in order to shut off your cold water supply. Always be careful. Your water heater may be hot, so try to avoid touching the tank.
