Floor Drain Trap Primer

For decades the plumbing industry has depended on water supplied trap primers for maintaining floor drain trap water levels thus preventing potentially dangerous and always annoying indoor air quality iaq issues caused by sewer gas infiltration into occupied spaces.

Floor drain trap primer.

The trap primer mitigates this problem by. Trap primers are used in plumbing systems to prevent floor drain traps from losing their water seal by evaporation. A trap primer or trap seal primer is a plumbing device or valve that adds water to traps the water seals in traps are needed to prevent sewer gases from entering buildings but because this water is exposed to the air it is subject to evaporation over time in infrequently used floor drains leading to the release of sewer gas into the environment. N an optional distribution unit can be specified when more than one trap is to be primed n a factory pre set timer is programmed to discharge water to the trap every 24 hours.

Singular electronic trap primers can be used to prime 1 or up to 4 floor drain traps with optional distribution unit. Maintaining the water seal will prevent the backflow of sewer gas into the buildings or rooms where the traps are installed. For a water supply fed type trap primer this happens automatically based upon a water pressure drop when there is flow within the potable water piping system such as using a sink faucet flushing a toilet etc.
