Taco Recirculating Pumps - Plumb N Plug
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.
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 Taco Recirculating Pump's 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 Degrees F to 115 Degrees F). All supply and return lines should be insulated for maximum energy savings.
