## Description

Watts Premier WP596816 Replacement Sensor Valve Kit for for Watts Hot Water Recirculating Pump, Silver : desertcart.co.uk: DIY & Tools

Review: Kitchen - Large water system so attachments re-rerouted hot water better
Review: I purchased the pump and one sensor valve years ago and it has and still works flawlessly, my only complaint had to do with the old fashion timer which is pretty much useless since I never really need the hot water at the same time everyday and whenever there are power outages, the timer stops and it needs to be reset. My water heater being in the garage, I usually have to move several things out of the way to access the pump and having the timer set for several hours to make sure you cover the time range at which you usually take showers is a waste of power (personally I had it ran for 2 to 3 hours in the morning and also in the evening). To alleviate this problem, I plugged the pump in a cheap WiFi connected plug (doesn't really matter what brand you use as long as you don't mind adding another app on your phone for the initial setup), I set the pump on the constant ON mode, then I purchased a couple of Echo buttons available for $20 on desertcart, created a routine in my Alexa app to turn ON the pump (via the connected plug), wait 10 min and then turn it OFF. Lastly, I setup the echo buttons to trigger the routine when I press on either one of the buttons, placed one in the bathroom and one in the kitchen, et voilà! Each time I really need the hot water, I press on one of the buttons, get my water almost instantly and I don't have to worry about power consumption knowing that 10 min later the pump will be OFF. Getting instant hot water when you need it and saving water and power at the same time! I highly recommend this product to anyone having to wait a few minutes to get hot water in the right places.

## Questions & Answers

**Q: So what this does is move the hot water through the pipes constantly, not just when you need it? Seems like an energy suck. Is it?**
A: If you run this all the time you will likely increase your water heating costs significantly as you are turning your pipes into a big radiant heater.  You can use the built in timer to only have it come on at set periods, but this will only work if you have a very fixed schedule.  I attacked this another way.  I plugged the unit into a TP-Link HS110 Smart plug that is Alexa controlled.  I can just say turn on hot water pump or turn off hot water pump when I want to control it.  But that was not good enough for me.  I found that if this pump ran for four minutes it would give me hot water at the distant shower that I wanted, so I did the following.  I wrote a routine to turn on the pump, wait four minutes and then turn it off.  While I can run this by voice, I bought the new Amazon Alexa Button, they are about $14 for a two pack.  The button is battery operated and communicates to another Alexa device.  Just before I take a shower I push the button and within four minutes the water will be hot without having to run water.

**Q: If the pump is on, and the water is hot, the sensor valve closes, right?  Isn't the pump trying to push water against a totally closed line?**
A: The pump just stirs water in the pump housing. It's not a positive displacement pump, so it has no problem doing that. But most of the time the control valve allows a trickle of hot water to flow, just enough to keep the faucet temperature at a constant 100°.

**Q: can i used without the sensor valve**
A: The control valve keeps the water temperature at the faucet at 100° by slowing the flow to a trickle. If you don't use the control valve, be prepared for the hot water to circulate at full speed and the temperature at the faucet to go up to whatever your water heater is set for.

**Q: Does this shut down the flow completely once temperature is reached or will it continue to trickle water into the cold water line?**
A: The valve allows a slow flow of water back through the cold water line, enough to maintain the temperature at the faucet at about 100°F. If you let the hot water run, the temperature at the faucet goes over 100°F, and the valve shuts off the back flow through the cold water line. After the faucet is shut off, the water in the valve will cool to below 100°F, and the valve will crack open and allow some flow to keep the water warm. The valve does not bang open and shut. It opens more or less, as needed to keep the water warm at the faucet. It doesn't depend on the temperature set at the water heater, except that if the water is very hot, obviously it takes less to keep the water warm at the faucet. The valve accomplishes this automatically.
