5 Tips for Troubleshooting Hot Water Tank Pressure 5 Tips for Troubleshooting Hot Water Tank Pressure

There are several things that can cause problems with your hot water tank pressure. No one likes a shower with no pressure coming from the shower head, so troubleshooting this issue can be quite helpful. There are a few things listed here that might cause this problem, along with suggestions on how to solve the problem yourself.

If you have an electric water heater,  make sure that you turn off the power at the circuit breaker before you begin. Should your water heater be a gas one, turn off the pilot light by turning the gas valve to off.

No Hot Water Tank Pressure at all

If the water has stopped coming out of the faucet completely, this is what could be causing the problem:

  • Faulty gas pilot
  • The thermocouple could be bad
  • The control valve for gas pilot might no bet working
  • The electric thermostat might be failing to work properly
  • The electric heating element might be broken

To try and fix the problem, check the flame and how good the pilot is actually working. Next, try to tighten or reposition thermocouple. If that does not work replace it with a new one. If you have a gas heater, you might try replacing the pilot valve.

Make sure that power is actually getting to the water heater if it is electric. If the power is making it to the water heater, replace either the thermostat or the heating element.

    There Is Some Water Pressure, But Not Much

    If there is not enough water coming out, you might be dealing with one of these issues:

    • The water heater is too small for the demands put on it.
    • The dip tube is allowing the cold water and the hot water to actually mix in the tank.
    • A gas supply problem or a control problem.
    • Faulty element or thermostat.

    In this case, make sure that the water heater is not being asked to do more than it was built to handle. Check the capabilities of your unit.

    Remove the dip tube and examine it to see if it is viable or if you need to buy another one. Check for connections that might be crossed causing the water heater to not function normally. Make sure that is not any water flow in the tank. If there is, you have a problem with crossed connections.

    If it is gas system, check for the flame and make sure that it is a bright blue with just yellow at the very tip. Propane should have a green glow with a tip of yellow.

    If your heater is electric, make sure that the connection is working. If there is power getting to the unit, replace the heating element. If the element is okay, then you have a thermostat problem.

      Rumbling Water Tanks

      If you find that your hot water tank pressure is followed by a rumbling noise, there might be sediment build up in the tank. If so, you just need to remove the sediment.

      Leaking Water Tanks

      If you discover that there seems to be water leaking from somewhere and you notice that the water pressure is lessening, then you should do the following:

      • Put a bucket or some large container under the overflow pipe; open the valve and clear any sediment that might be present. If it is still leaking after that, you should replace the valve.
      • You might be able to fix it by setting the thermostat at a lower temperature to keep the water heater from overheating.
      • Check the bottom of the water heater itself and if there are any rust stains present then you will have to replace the entire water heater.
