I have two tankless water heaters at the moment. One was starting to stop heating the water after five minutes or so and no one seemed to want to come try to fix it because of its age. It was throwing a temperature sensor error code. I had never flushed it since it was installed about eight years ago. I saw some videos on the importance of flushing tankless water heaters so I bought this kit. Very easy to hook up and run the flush. That resolve the problem. I flushed my other one as well and will now do it every year or so per the suggestions. This is a very worthwhile investment.

Pump works very well. The upgraded metal braided hoses are the easiest to work with and store for future usage. The bucket is a little bit large. It’s a 3 gallon pail, but everything fits into my 2 gallon pail also.

I used the Superior Pump 91660 Tankless Water Heater Descaler Pump Kit to descale my tankless water heater, and it worked flawlessly! The instructions were clear and straightforward, making the process simple even for someone not particularly familiar with water heater systems.The pump was easy to set up, and the non-toxic descaler solution provided peace of mind. The entire process went smoothly, and I had zero issues. Highly recommend this kit to anyone needing to maintain their tankless water heater.

This is the first time we flushed our tankless water heater. Our plumber recommended we do it ourself using a kit since it would save so much money and these kits can be used over and over. It was a very easy process using the kit and YouTube video. I’m glad we got this. Worked great and nice knowing we saved a lot of money doing this ourselves and that we can use this kit over and over again.

Everything worked as it should have. I was able to save money flushing my tankless water heater instead of paying someone to do it. I would recommend this kit. Good pump quality.
