Review on Watts Premier WP367010 Recirculating 0955800 by Cody Hunt

For a Watts circulator pump to work you need one of these sensor valves at the farthest point for the whole system to work. If hot water is needed immediately, this is one option and probably the least expensive. Pros: This touch faucet was easy to install as long as there was enough space under the sink to work. You feel like you have hot water right away. Cons: For a simple valve, this is quite expensive and there is a slight water hammer when the sensor is in the open state. When the valve is open, cold water flows toward hot water, making the hot water warm instead of hot. Until the touch valve closes, you have to be content with warm water. The solution to this is to run the pump for 15 minutes or more. Finally, this valve is necessary, because without it, the Watts circulation pump will not work efficiently.
