Exactly the part we were looking to purchase
It was so convenient to find the part and have it here so quickly. I also ordered an o ring pack for the parts I ultimately ordered. Everything was perfect!

Easy fix, but you MUST know this…
My Navien was no longer heating water at some of my faucets. The shower worked because of its greater volume of water. This flow switch fixed the issue. But this is a very important detail - you must remove the o-ring from the old sensor and place it inside the new one. The new one doesn’t come with an o-ring. If you fail to do this, your Navien will leak water from the overflow drain and from inside. This was a big shock to me. Luckily, I found a Reddit thread about leaking after flow sensor replacement and the issue was the o-ring. Replacement will take 10 minutes after you drain the system. If you don’t drain it, expect to get wet.

Defective product
I have now purchased two of these- both don’t work. First one didn’t work right away and the second failed on the third day after installing. Returning both and reordering - hopefully the third time will be the charm.
