Reddit take

Not enough linked mention summaries yet; the source excerpts below are the evidence.

Pros

  • Moen flo is a flow monitor and shutoff if you want an reintegrated solution.
  • I can highly recommend this system, I have one myself. You'll also get a letter from Moen that you can print and hand in for a potential discount on your insurance.
  • If not wanting to get into the plumbing/automation technical side of things it sounds like while expensive - the Moen system will be the best best. There's not a lot of these devices on the market but it seems this one is the most reputa...

Cons

  • Consider getting a Moen Flo or Phyn Plus in addition to the water sensors. Those can shut off your water in the case of a leak.
  • I'd steer you away from Moen Flo: - the device is expensive - requires plumbing (more money) - proprietery/cloud based - has a known impeller design flaw
  • Downside: it's cloud based :/
  • After reading reviews of the Phyn and Moen Flo, combined with the price, i'm extremely apprehensive to install them. Plus if they do fail, its more of an effort to replace, than just to remove and use the ball valve again.
  • This means that getting up and showering at 4AM when the system has learned that you're usually up at 7 will shut the water off mid-shower... Many times my wife would yell for me to turn the water back on, until it figured out her pattern.

The little impeller that measures flow uses a mirror and it gets gunked up with silt and stops recording since I have no upstream filter. They do sell a replacement as cleaning it with vinegar is not as effective as it should be. I had an early model with the green knob and it stopped working and I needed to RMA it. ... It has AI to try to figure out what is using water. It’s not bad at the job, but it does struggle with smart irrigation that have variable durations like Rachio (seems better recently).

He said that a lot that he has installed the homeowner has had him remove because the valve keeps shutting when it shouldn't and other issues.
