Taco Plumb N Plug Recirculating Pump  006-B4-4PNP.

Waiting for Hot Water is a common problem: turn on the faucet or shower for hot water, then wait for it to arrive. In fact, the wait can be up to two minutes in larger homes with multiple bathrooms and long runs of pipe between the plumbing fixtures and the water heater! With a Taco Domestic Hot Water Recirculation System in place, there’s no more wait. Instant hot water!

Waiting for hot water sends millions of gallons of cooled water down the drain each year. In fact, an average family of four wastes up to 14,000 gallons of water each year waiting for hot water.* Water conservation is so important that many US states and municipalities routinely impose watering bans and offer rebate incentives to help conserve this natural resource. *Source: Dept. of Energy study BTU’s and starting over with fresh, cold water to heat up requires even more heat energy. So in addition to wasting water, millions of BTU’s and energy dollars are wasted, too.

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 in the early morning and late afternoon. 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.
