    Titan Water Valve

    Easy to install and setup in Hubitat and integrate into the safety monitor. I did need to move my hub closer for the initial pairing but overall was easier than I expected to get installed and working.

    Great upgrade from the old zooz valve shutoff

    I was happy the sale took place so I could replace my water valve shutoff with a titan. No more guessing if it will actually work!

    Quite impressed, instructions could be a bit better, though.

    I really like having the peace of mind of having this water valve. It also comes with it's own built in water sensor. I also plan on adding more water sensors to various areas of my house.

    I found it quite easy to install. It still worked on PEX pipe and you can adjust the clamps up and down to get around the pipe fittings around the valve.

    I compared this with Moen Flow. I went with this one since people were complaining how the moen one would randomly shut off at inopportune times. I also went with this one since I didn't want to mess with plumbing. There is no way for it to monitor the flow rate, unlike the Moen Flow, however. I don't know if it would be that helpful anyway, since my RO system tends to trickle run to fill the tank and it might "look" like a leak.

    I did struggle a bit at first. You have to read the instructions VERY carefully! There is a small ring that goes between the ball valve and the actuator and it would not work on my ball valve handle without this ring. I also was disappointed that the printed instructions did not indicate how to troubleshoot pairing. I needed to search online how to do it. Once it was paired, though, it worked well. Hopefully it will be worth it's cost! Definitely helpful for peace of mind.

    It was easy to install

    This installed easily and connected to my HA system easily. I used to have a dome unit, but it failed after 4 years.

    Worth Every Penny

    Got this after a somewhat expensive water heater failure soaked the basement. I wasn't sure it would work due to having CPVC piping as well as a hard to turn shutoff valve. It was easy to install and immediately did its thing during the initial setup. Added a Zwave leak sensor to the base of the new water heater seeing as it's across the room from the house shutoff valve. Dribbled a bit of water on the floor at the sensor and within seconds it shut off the water supply. I'll sleep easier knowing that this has me covered.
