Premier's Instant Hot Water Recirculating System is a pump and valve combination that delivers hot water in an instant to any faucet or bath in your home. It uses the pump at the water heater along with the patented under-sink sensor valve installed furthest away from the water heater. This combination creates a pressure differential that allows the cold and cool water in the hot water supply line to "by'pass" (at a low volume) into the cold water supply line through the thermostatically controlled sensor valve, keeping the water in the hot water supply line at a "no-wait" temperature throughout the home. The timer on the pump makes it more efficient during downtime.

How Much Water is Wasted Waiting for It to Get Hot?


  • An average home has approximately 125 ft of 3/4 inch piping.
  • 125 feet of 3/4" pipe holds 3.14 gallons of water.
  • 10 draws per day wastes over 31 gallons of water waiting for the water to get hot.
  • Over a year, the wasted water equals 11,461 gallons.


  • Works with any standard hot water tank heaters and tankless hotwater systems*.
  • *May not work with a tankless water heater check you tankless water heater manual for details.


  • Home and Business applications.

Hot Water
We installed this in our home because we weren't getting any hot water at the other side of the house. After we installed this, it worked within a few hours. We had to buy more of those sensor kits but it was worth it. Way better than our other solution. Just make sure you buy enough of the sensor kits because you'll need it for a lot of the areas that don't get hot water. You only get one in the box.

BEWARE IF YOU HAVE NATURAL GAS YOUR GAS BILL WILL RISE DRAMATICALLY MY GAS WENT FROM $14.99 PERMO TO $37.99 IF YOU LET IT RUN 24/7 I HAVE SINCE TIMED IT FOR 2 HRS IN AM AND 2 HRS IN PM..IT IS NOT IDEAL I installed the pump and 2 sensor one in kitchen and one in upstairs bath. it works fine but if i were to install one more sensor ti would service the 2nd upstairs bath better. Yes it works fine…BUT IS IT WORTH (IN MY CASE) $264 PER YEAR IN EXTRA GAS AND THE $259 FOR THE PUMP…IT IS YOUR CHOICE.. I AM THINKING OF TURNING IT OFF… ALSO WHERE SENSORS ARE THE WATER NEVER REALLY GETS COOL LUKE WARM ONLY

Hot water fast
It took me some time to read install but easy. I'm pretty handy so it wasn't too bad. I've had it for about 2 months now and I can't really complain. Thanks for the great service.
