This sensor bypass valve is a must-have addition to any hot water recirculating system. I installed it in the laundry sink on the second floor, paired with a Hot Water Recirculating Pump set to automatic. Now, we no longer waste five minutes of water waiting for hot water to reach two stories up from the basement. The installation was straightforward, but you will need two additional 1/2" x 1/2" FIP flexible faucet supply lines for proper connection under the sink. The valve functions perfectly, providing near-instant hot water and making daily tasks much more convenient. The only minor drawback is that the cold side runs warm at first, but it cools down within a few seconds of running just the cold water. The build quality is excellent, and with a five-year warranty, it’s a solid investment for long-term efficiency. If you want to improve your hot water system, this is a great solution!

This replacement sensor valve for a hot water recirculating pump system by Sxmprail is just like the OEM version but for far less cost. If your sink, shower, tub, etc is no longer providing instant hot water but the pump is stilll working, then it likely is a a bad sensor valve. Also, with the addition of a couple of hoses, you can use this replacement valve to set up a second or third instant hot water zone.Review for: Sxmprail 595926 Replacement for watts premier sensor valve, Bypass Valve for grundfos UP Comfort Series and 500800&500805 watts premier Instant Hot Water Recirculating Pump System, Five Year Warranty 2410-137

This value is designed to be paired with a hot water recirculating. The pump goes at the water heater and the valve is installed at a distant fixture. It allows hot water to be pumped to the fixture for “instant” (more like quick) hot water at the fixture. Because of hard water sediment, they have to be cleaned or replaced every few years. This one works as good as the original that was included with the pump and works as expected.

The valve came with some very good preventive maintenance instuctions to prevent calcium build up. Thanks

This valve looks and feels identical to the oem. I havent installed it, but I will report any issues upon installation. I took one star off because it comes with no parts required for its installation - it needs two 1/2" Female to 3/8" Male Reducer Adapter, because standard faucet hoses wont fit without such adapter on each size.

IMPORTANT UPDATE 10 March 2025 16:14 PSTDocking one star. So... had this installed along with a pump on the hot water heater and it worked fine for two months. Then, kind of suddenly, the kitchen sink flow went to almost nothing. Checked faucet screens and found some tiny black debris. Cleaned that out, but still very low flow. Removed stop valves but they were clear. Finally, after seeing a YT video where the gentleman used this rather innovative technique, I backflushed the faucet lines with a garden pump sprayer and the black bits you see in the photo came out. Much better flow, but still not right. I expect the cartridge has some more of those black bits in it and will need to be replaced.SUMMARY: Apparently there are quality control issues. The valve does work. I tested it thoroughly, but apparently the finish work on the valve is lacking. You can use it, but flush it out thoroughly beforehand. It would be good idea to install screened gaskets inline before your fixture, also, if that's possible to save you the hours I spent tracking down the issue with my kitchen faucet.You need flex pipes to fit the valve to your existing hot and cold water valves, and then flex pipes to fit between the sensor valve and your faucet connections. This valve is used in conjunction with a circulating pump that you install on the hot water OUT line of your water heater. I installed on a tankless type water heater, so double check on YT to get details if installing on a regular tank water heater to be sure it's similar.THis setup typically, as in my case, uses the cold water line as a return line, which does mean that you'll need to run the cold water for 30-60 seconds before it runs cold. It'll run lukewarm before that, but the advantage is,, of course, hot water right away on whichever faucet you choose to install it on.I have a Watts brand sensor in the bathroom and this one is a bit smaller but it works OK and hopefully will last at least as long as the circulator pump. My reservation about durability owing to smaller size is the only reason I didn't go for five stars.One suggestion is to put your pump on a smart outlet so it's not able to run 24/7, increasing your energy cost. Also, on the pump, get one with three speeds and a flow switch, which will also maximize efficiency and keep costs down.
