How to Compare Water Softeners

Beware!!! Most brand name water softeners sold are undersized for homes!

Minimum IPC Service flow rates for homes

2 Bedrooms 16.8 gallons per minute (GPM)

3 Bathrooms 18.5 GPM

4 Bathrooms 21.1 GPM

It is critical that water softeners be properly sized for your home. The softener must soften water at the minimum IPC flow rate for your bathroom count.  Water softeners that do not meet plumbing requirements may restrict the flow of water and decrease water pressure.
Undersized softeners can also "bleed-through", where some hard water is allowed through the system, defeating the purpose of the system itself. Ensure the water softener flow rate meets modern plumbing code requirements for you home size. Also confirm all water softener pipes, connections, and valves have a minimum diameter of one inch and any flow rates are measured in gallons-per-minute (GPM).
Jason's Water Systems service flow rates have been certified by the National Association of Home Builders Research Center.
Beware: Many well-known companies install "modren" water softeners that do not have high flow.
