The flush kit worked as advertised. Easy set up. Directions were clear. It paid fo itself the first time I used it. My plumber charges $135 for a tankless water heater flush.I had three heater to flush. THe flush kit cost $135. Vinegar for the each heater job was about $6.00. I saved about $250.

      Easy and Efficient
      This helped flush my Rinnai tankless. Let it run for a whole hour and just used 2 gallons of normal 5% diluted vinegar (that's really all you'll need). It was super quiet and cleanup was easy!

            Works as intended but I feel like it’s way overpriced. The pump retails for 74$ and with the adapter for the hoses you’re looking at 80$. Throw in a couple hoses and a bucket and you are still under a 100$. Could have probably saved 50$ buying everything separate.
