Important water quality parameters may include hardness, iron, chlorine, chloramine, arsenic, pH, manganese, sulfides, sediment, and more. If sizing a commercial softener, only hardness and iron (if well water) is required.

NOTE: If you do NOT have water quality information, fields will be automatically populated with default values and you will be given the option to have WCC test your water. Always verify your sizing once you have real data. Default values may not be accurate!

WCC recommends softening both hot and cold water anytime hardness levels are over 8 grains per gallon or iron levels are over 0.2 ppm. If hardness/iron levels are lower, you may opt to soften hot water only in order to reduce space and budget requirements.

Note: that light scaling of fixtures may still occur, even at lower hardness levels

Default value is NO.” If YES, WCC may be able to provide high temperature tanks and valves (maximum working temperature 160˚ F (71˚ C).

Note that this will increase system cost and lead time.

Though every building is different, WCC normally recommends selecting a maximum pressure loss of 25 PSID if dynamic incoming water pressure is 55 psi or greater. For incoming dynamic pressure between 40 – 54 psi, WCC normally recommends selecting a maximum 15 PSID. WCC does not recommend selecting a maximum 7 PSID unless dynamic incoming pressure is lower than 40 psi – or if special site conditions exist.

NOTE: selecting the wrong value may result in an incorrectly-sized system!
