Based on national averages. Different trap primers may have different outputs.

Calculation based upon a continues trap primer which uses 131,000 gal water per/yr.

Calculation based upon electronic trap primer which uses half the amount of running time which is a 12 hour cycle. 65,500 gal water per/yr. More new construction use this rather than the continues trap primers.

Calculation of  drains with Differential Pressure Primer based upon (Number of Drains / Toilets /Trap Guard), (Number of times flushed per day),  (Gallons used per number of flushes and Drains/Toilets). This is not commonly used, when you flush a toilet it averages 2 gallons of water  per flush which when flushed 1x per day using 730 gallons per year which equates to 3/10. Majority of the marketplace currently in 2015
