Water Pressure Tank Sizing

The is a direct link between the water pressure tank sizing and the energy use.

Water pressure tank sizing.

This should not be confused with tank volume for example a pre charged tank with a tank volume of 20 gallons has only five to seven gallons drawdown capacity depending on the cut in cut out on off setting of the pressure switch. Pressurized well tanks extend the lifespan of your well pump by preventing rapid on off cycling of the pump and maintaining water pressure throughout your home. A pressure tank is an integral part of maintaining your well. It s important that the size of a tank is adequate for your.

Tank drawdown capacity is the minimum amount of water stored and or delivered by the pressure tank between pump shut off and pump re start. The more a pump must run the more wear and tear occurs to the pumping mechanism and the electric motor. As a general rule it s usually safer to err on the side of a larger tank. Sizing a water pressure tank properly keeps the amount of run time to the water pump held to a minimum.

Similarly if you are using the smaller sized pressure tank for larger requirements or greater use the energy consumption will still be higher. If you are using the larger capacity pressure tank sizing for smaller use the energy consumption may be higher. An under sized pressure tank can cause a water pump to run an excessively. A properly sized pressure tank ensures your household water needs are met and your pump is protected against short cycling.

A tank which is too small for the water demand may result in pump overuse. Join john woodard our master water specialist.
