What is PPP trap primer?

The Model P-1 Trap Primer Valve is a precision device designed to deliver potable water for 1 – 4 floor drains. A pressure drop of 10 PSIG (70 Kpa) is required to activate the priming valve. The Trap Primer must be installed on cold fresh water lines of 1 1/2″ diameter or less.

Where do you put trap primer?

The trap primer valve should be installed vertically at least twelve (12) inches [305mm] above the grid of a floor drain, or the flood rim of the equipment which the trap is to serve.

How do you install floor drain trap primer?

The Trap Primer must be installed on a cold fresh water line of 1 1/2” dia. or less. Must be installed near a fixture that creates a minimum of 10 PSIG pressure drop. Do not install on water heater line due to insufficient pressure drop. Do not subject Trap Primer Valve to pressure in excess of 125 psi.

Does a trap primer require an air gap?

Trap primer adapters are installed on the floor drain outlet prior to the P-trap. An air gap is a vertical break between the supply pipe and the receiving source to provide backflow protection into the potable water system.

How does trap primer work?

The primer connects to a drinkable water supply. When pressure per square inch (PSI) is sensed — such as from a nearby toilet or sink — it adds some of that water flow to the trap. Other methods. Some trap primers work on timers (based on your settings for when a home is unoccupied).

How do trap seals work?

The trap seal is a device with a one-way valve that allows water to flow down the drain but forms a seal that stops air from escaping up from the drain. A trap seal is much easier to install and maintain, and there is no worry about fixture use, fixture type, or water pressure.

How do you attach trap seal primer?

If using trap seal primer, insert connection tube into primer adapter. Otherwise, remove adapter. Apply thread seal tape to threads of primer plug and screw in plug to seal the outlet.

Why do I need a trap primer?

Trap primers are used in plumbing systems to prevent floor drain traps from losing their water seal by evaporation. Maintaining the water seal will prevent the backflow of sewer gas into the buildings or rooms where the traps are installed.

Are trap primers required by code?

Plumbing codes require that trap primers be provided for “emergency” floor drains and other traps subject to evaporation. An example of an “emergency” floor drain is one in a toilet room.

How does a trap seal primer work?

Trap seal primers provide a supply of water to replenish the deep seal or “P” trap of a drain to prevent sewer or potentially explosive methane gas from entering the area through the floor drains.

Do trap primers fail?

When a trap primer fails, sewer gas, bugs, and unpleasant odors can enter the building through the drain. Green Drains’ patented, easy to install design solves these common issues as water can freely pass down through the Green Drain, but gases, bugs, and odors are blocked by the one way seal.
