Question 4

Trap Primer

Answer 4

A trap primer is a device that causes a small amount of water to drain to the trap via piping from the trap primer. 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.

Another type of trap primer can flow water from the potable water system to multiple floor drains/traps. This type of trap primer consists of an automatic timer, electric solenoid valve, vacuum breaker, and a piping manifold with valved outlets, which are each piped to a floor drain trap.
