How does a constant pressure system differ from the standard system?

A constant pressure system uses a motor controller that runs the well pump at varying speeds, depending on water usage demands. A standard system has a 20 psi window for replenishing water used. As water is used, the tank pressure

may have to drop to 40 psi before the pump starts; the pump will continue to run at full speed until it builds to 60 psi. (Note, this 20 psi window can be set to start and stop any 20 psi window – e.g., 45 to 65 psi.) A constant pressure system typically has a 2-5 psi window, allowing for appliances – like point-of-use hot water heaters – to retain a constant flow rate. A constant pressure system is most noticeable when doing the laundry and showering at the same time.

Recent FAQs

What is a well screen?

If the bottom of the well is in sand and/or gravel, the well driller may install a well screen. The well screen is a metallic cylindrical sieve-like structure which is usually attached to the bottom of the well casing or other water intake areas.

What is a pump screen?

A pump screen is a combination of a coarse stainless-steel shield and a fine screen that completely covers the pump. This disallows sand and gravel particulates from entering your water feed stream. This does slow the gallons per minute (GPM) of the pump while still allowing enough water to supply the house.
