The OREGON #1 Trap Primer Valve is a
diaphragm operated primer which delivers a fresh
water prime to seldom used floor drains. This primer
requires no adjustment but must be installed on a
cold fresh water line of 1 1/2” (38mm) diameter or
less. The primer valve is automatically activated when
it senses a pressure drop of 5 to 10 PSIG (35 to 70
kpa). The valve’s operating range is 35 to 75 PSIG
(245 to 525 kpa).
