Automatic Trap Primer Valve - Precision Plumbing Products

This innovative trap priming system automatically primes up to four floor drain traps using our patented water distributsion system. The PRIME-RITE requires no adjustment but must be installed on a cold water line of 1-1/2" (38mm) diameter or less. The priming valve is automatically activated when it senses a pressure drop of 5 to 10 P.S.I.G. (35 to 70 kpa). The valve's operating range is 35 to 75 P.S.I.G. (245 to 535 kpa). All PR-500 Valves include integral vacuum breaker parts.

The PR-500 Prime-rite trap primer is an easy to use and install product. It has a ½” inch inlet and outlet to connect to most normal lines and can be installed on cold water lines 1-1/2” diameters or less. The PR-500 also adjusts to line pressure to keep you from worrying about the trap primer when it’s in use.

• 1/2" inlet/outlet
• Installed on cold water lines of 1-1/2" diameter or less.
• Automatically adjusts to line pressure
• One priming valve will prime 1 to 4 floor drain traps, using the water distibution system
• Machined from CDA 360 corrosion resistant brass
• Does not contain springs, diaphrams, or plastic parts

* The priming valve must have a minimum elevation of 12 inches above the finished floor.
• CA/VT compliant

Why We Need Relief Valves

Ever wonder what would happen if a relief valve failed or was plugged? This short video on Youtube from Mythbusters shows just what can happen. These guys constructed a mock up of a 2 story house and set a 53 gallon electric water heater in what would be the basement. They plugged the relief valve and monitored the temperature and pressure from a safe distance. What happened a few minutes later will amaze and frighten you at the same time.

Domestic Hot Water

The Problem:
Waiting for Hot Water
It’s a common problem: turn on the faucet or shower for hot water, then wait for it to arrive. With a Taco Domestic Hot Water Recirculation System in place, there’s no more wait. Instant hot water!

Waiting Means Wasting
Waiting for hot water sends millions of gallons of cooled water down the drain each year. In fact, an average family of 4 wastes up to 14,000 gallons of water each year waiting for hot water.*

Energy Down The Drain
Of course, all that “waiting water” contains some heat energy (BTU’s). Wasting those BTU’s and starting over with fresh, cold water requires even more heat energy. So in addition to wasting water, millions of BTU’s and energy dollars are wasted, too.

The Solution:
Install a Domestic Hot Water Recirculation System.
The Taco Plumb n’ Plug® Recirculation System is specifically designed for:

• Instant hot water comfort
• Water savings
• Energy savings

How a Domestic Hot Water Recirculation System Works
A standard DHW system requires a dedicated return line from the furthest fixture back to the water heater. The return line is connected to a tee at the tank drain valve or to the tank’s cold water supply line. A Taco Plumb n’ Plug® recirculation pump with an optional Integral Flow Check (IFC) is installed on the return line and controlled by a timer or temperature aquastat. The spring-loaded IFC prevents gravity circulation during off-cycles. The timer turns on the pump at preset intervals, usually during peak use periods. An optional Aquastat operates the pump to keep hot water in the line within a set range (95°F–115°F). All supply and return lines should be insulated for maximum energy savings.
