Troubleshooting your Water Heater

Common issues with home water heaters include:

Not Enough Hot Water

If the last person in the household is getting a cold shower, there are a a few simple things to check first. First, check your water heater’s thermostat. You can try increasing your temperature within the manufacturers' recommendations. You may also need a larger tank, especially if you have new members to your household. If your tank is leaking, or if any part of it appears cracked or broken, call a professional immediately.

Water is Too Hot

The problem is probably with your heater’s thermostat. Check to see if it’s turned too high. If it isn’t, it could be malfunctioning. Mark the current position and then turn it to a cooler setting. Wait a few hours. If the water is still as hot as it was before you turned the temperature down, either the thermostat isn’t working, or there is a mechanical failure like the TP valve, which isn't an expensive fix by a professional.

Water Takes Too Long to Reheat

If your water takes too long to heat up it could be due to an old or broken heating element. In some cases, we can just replace the element. It could also be sediment in the tank, inhibiting proper element functions. Flushing the tank every year can help extend water heater life, and avoid issues.

Water is Rust Colored or Smelly

First of all, check to make sure it's not your water source. If it's only with your hot water and not cold, it is usually minerals and sediment in your water tank. Flushing the tank can help, but you also made need your anode replaced, which acts as a rust magnet and keeps your water heater from rusting out.

Valve or Tank is Leaking

If the water tank is leaking, it needs to be replaced. If the valve directly below the tank is leaking, you may still have options. Our experts technicians will see if it's a simple valve replacement, so the faster you call, the cheaper the fix may be!
