Review: Will Save Me $$$ On Water! - I wanted to wait a while before reviewing this device to gauge it effectiveness. It's been installed about a month now. I have a 2000 square foot home sitting on a slab, so my water lines (Pex) are in the attic. Although it does not get terribly cold in Southern California during the Winter, it used to take upwards of 30 seconds before the water would get warm. That was a lot of perfectly good water going down the drain. After installing this device, it now takes only 5-7 seconds before the water starts to warm up. Interestingly, the closer the faucet you are opening is to the valve, the sooner your water will become warm/hot, so I find that the sink next to the one with the valve (in our master bathroom) gets the water warm-to-hot within just a few seconds. It's important to tell you that the water will not be piping hot and waiting for you right when you turn on the faucet, but the amount of time, money & water you will save is still worth it. The pump attaches to the top of your water heater and is VERY quiet. After installation, I had to touch it to make sure it was running. Although I have mine set to "On" 24 hours a day, I appreciate the timed feature that allows you to turn it on and off at certain times of the day. It runs on 110 volts, so you may need to buy an extension cord to plug it into an outlet in your home or garage if it's not close to an outlet. As mentioned elsewhere, check the WATTS website before buying as apparently this device will not work with all water heaters. I failed to do this, but I was lucky. Also, it will not work with a tankless heater so do not try it! As far as installation goes, I'm fairly handy around the house, but plumbing is not my strong suit and I scoffed at the notion that I could install this in one hour. However, it took just a little over one hour (as advertised) to install with the only hiccup being a crowded space under the sink where the valve was installed, causing me to get creative with the hose routing and placement. Don't feel like you have to mount the valve to the wall. Mine is working just fine without mounting. I didn't even need to bring out my plumber's tape/pipe dope because everything sealed up great the first time. As an aside, while you have your water heater dismantled, go ahead and drain it. It's probably been a while. My wife was thrilled when I (finally) installed this device after maybe 3 years of her asking. She heartily recommends it and so do I.
Review: Well worth the money and SO easy to install. - After years of waiting for water to reach the far areas of my house, I had finally had enough. This pump exceeded my expectations and works flawlessly. It sat on my counter for a few weeks until I finally decided to install it. Installation time was less than 30 min. It took me longer to get the junk out from beneath the far sink than it did to install. The instructions are straight forward and easy to understand. I did the under the sink valve first. They supply you with all the right hoses and connections. I did have to get long hoses, but that is not the fault of the mfg. My supply pipes are further apart. I bought longer hoses and everything was golden. Installing the pump was beyond easy. Yes I did have to buy the correct CPVC fittings with 3/4" threads to connect to the pump. Less than a dollar at the local hardware. Off the discharge pump I went with a flexible hose that connected to my system. You will have to buy a few extra pvc fittings if you need to make it work with your water heater system. It took less than 30 min to install in total and I plugged it in. I could tell it was working, but the pump is extremely quiet. We set the mode to timer, because we want it on from early morning to around 11 pm at night then the timer shuts off the pump. You will still have hot water, but just not as fast as when the pump is working. Even if you let it run all the time, it would cost around $20 a year, tops, but the timer is a nice feature. So far I am extremely happy with the product and it has hot water at our furthest sink within 5 seconds. Don't hesitate to buy this product.

## 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.

### ⭐⭐⭐⭐⭐ What a difference in a big home!
*by J***N on April 10, 2020*

I can honestly say this is probably the most cost effective way of getting hot water to far places in a home, Our home 12 years old is roughly 3000 sq ft 2 story with 4 full baths with the master being at the most furthest point of the home upstairs roughly 100+ feet away from the hot water tank in the garage between the master bath sinks, jetted tub and shower I would have to wait almost 4 minutes of water running before it got warm then cold. The water lines used throughout the home are PEX non metallic plumbing. The pump and sensor unit are very easy to install on your own with a bit of common sense and took me about 40 minutes to install. I let the pump do it's thing for about 30 minutes went up to the 2nd sink in the master bath, which is the last and furthest in the home only 3 feet further than the 2nd sink, within approx 3 secs the water was warm to the touch followed by hotter water very shortly thereafter. I had my wife verify this later that evening, we would usually waste a bunch of water filling up the jetted tub or turning on the shower waiting on hot water, again within seconds the water was warm then hot! I was very amazed as I was getting prepared to drop a few thousand $$$ to have a Tankless installed just for the upstairs master bath I am very pleased with this system. Now I have seen where some people are concerned about cost to run this etc. first it waste no water so right there whatever the cost should be outweighed in water savings. Second I have seen people mock those about putting this on a smart timer since it already comes with a built in timer, what those doing the mocking are not realizing is that if the power goes out then the built in timer does not keep its correct time once power is restored, Yes I'm sure for many this is probably a very rare thing, but I can tell u you here in Northern CA the power especially in the summer is 50/50 at best! So yes I would highly suggest the use of a smart plug for one of these, I already have dozens of smart plugs/lights & switches in use at my home so I did not need to purchase one but they can be purchased for less than $25 I recommend Tp-link by Kasa! The other nice thing about the smart plug especially if it has the energy monitoring option (Not all do get one with the monitoring) is that you can get a real time look at what the power consumption is daily, weekly and yearly to kind of give you a idea of the Electric use which is not bad. The pump averages right around 22 watts +/- while running the company states is should be less than a nickle a day or so to run 24 hours. I may set up a schedule or Alexa routine but currently I have not having 48 345 watt solar panels and Battery I am not to concerned about 22 watts running. On to the gas usage, given we have a large home along with large heated pool/Jacuzzi and outdoor gas fireplace etc. we have a very large diameter gas line with a smart meter. I can always here the meter gurgling so to speak when any of the large items are being uses including the hot water tank, to date after checking numerous times I have yet to hear the gas meter or the actual hot water tank firing constantly, not saying it does not fire up once enough coldwater gets pushed back into it I am just not hearing it like a normal tank being heated up! So again I do not believe that the complaint of this using mass amount of utility to use 24/7 again as compared to dupping 100s of gallons a day down the drain I fully believe at best it is a gain in savings at worse it is a break even! I did have to purchase a second sensor kit to place in the kitchen downstairs as our home has a branched Hot water line since doing so even our kitchen sink water is now warm to hot within seconds. I have yet to experience the so called major bleedback into the cold water line that some have stated happens that when they turn on the cold water it is warm to hot for a brief moment, either way even if I did it is still worth every penny for this setup!
