The Trap-Defender is a pressure drop trap primer that releases water into the trap with any drop in pressure above 5 PSI. The Trap-Defender can be located in remote areas. It is superior to flow type trap primers in working with low flow fixtures and it also works with pressure spikes.
Jay R. Smith Mfg. Co.’s Trap-Defender is engineered to prime a single trap or multiple (4) traps with the use of a distribution unit (Fig. No. 294DA-ABS) designed to distribute water evenly between traps. The device should be located within 20’ of the floor drain trap. The trap primer valve shall be installed a minimum of 12” above the finished floor.
For periods of low water usage due to holidays or down periods, the Trap-Defender is equipped with a manual trap priming lever that allows maintenance to fill empty/low traps and clean/test the trap primer.
