Tankless Water Heater Descaling Flush Kit Includes Submersible Utility Pump with Adapters 3 Gallons Pail with Bucket Lid Opener and Two 3/4" GHT X 6FT PVC Black Hoses Easy Installation to Clean

Great product. Very easy to setup and use. A solid long-term maintenance investment.

Worked great.A word of caution: when you turn the cold water back on to flush the vinegar out, clamp the hose to the bucket. This kit does not come with a clamp. Otherwise, the water pressure makes it flail around wildly…and vinegar in the eyes is no fun

Had no problems worked as expected and was able to flush the tankless hot water heater. Looks like the hoses and pump will last a long time for my once a year flush of the hot water heater.

Like many others, our contractor never told us about regular de-scaling of the tankless heater, so when the water turned cold in the middle of wifey's bath, her screams sent me troubleshooting. Of all the possible causes I found, this seemed a good (and the least expensive) place to start. It was easy to set up and use, but after running it for an hour there was little visible debris in the bucket. However, the water was quite cloudy so maybe there was a lot more stuff that came out in a dissolved state. Anyway, since running the process one week ago the hot-to-cold water problem is yet to recur. If it does I will update this review accordingly, but so far, so good.

This is all you need (other than white vinegar) to flush out your tankless water system.Good quality and reasonbly priced.

Used once and it rusted through. Get something else.

It had me a little worried at first, it runs a few minutes and then it shuts down a little. Thought something was wrong at first, but that is the way it is supposed to do.

Discovered that I had not cleaned my Renai hot water heater in several years since owning my new home. Found this pump and it came with online easy to understand and explain how to use video. Worked great highly recommend!
