What is prime Rite?

The Prime Rite automatic pressure drop activated trap primer valve will prime up to 2 floor drains with our patented distribution DU-U and DU-4 units. System operating range is 20 psi minimum to 80 psi (138 to 552 kpa) maximum.

What is a p2 valve for?

The Model P-2 Trap Primer Valve is a precision device designed to deliver potable water for 1 – 2 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.

What is a pressure drop activated trap seal primer?

Trap-Defender™ is a pressure drop-activated trap primer designed to be connected to any potable cold water line. It is automatically activated when a pressure drop as low as 3 psi occurs in a potable cold water line. Water is released into the floor drain’s P-trap to maintain a seal.

What is a trap primer valve?

A trap seal primer is a flow control valve that adds water to a P-trap to maintain a water seal, preventing sewer gases from entering a building.

How do you adjust a trap primer?

To adjust: Turn adjusting screw counter clock- wise until a steady flow is produced. Turn adjusting screw clockwise until dripping just stops. Primer is now set to line pressure. Cycle primer at least (5) times to insure proper activity.

How do you install trap seal primer?

Install in a frequently used horizontal cold water line above the trap to be protected. 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.

What are trap seals?

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 P trap primers 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 much water does a trap primer use?

4-8 ounces
A water-supplied trap primer typically uses 4-8 ounces of water at a time. Some models are adjustable. After adding evaporation and multiplying the number of drains in a commercial building, the water use can quickly turn from ounces to many gallons per hour.

How do you install PPP 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 in- sufficient pressure drop. Do not subject Trap Primer Valve to pressure in excess of 125 psi.

Is a trap primer necessary?

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. Trap primers must conform to ASSE 1018 or ASSE 1044 standards – ASSE stands for the American Society of Sanitary Engineering.
