Superior Pump 91660 Tankless Water Heater Descaler Pump Kit with Non-toxic Descaler Solution, 3.5 Gallon, Deluxe

I bought the Superior Pump 91660 Tankless Water Heater Descaler Pump Kit to descale my tankless water heater, and I’m honestly impressed. The pump seems very strong and moved the solution through the system without any problems. It had plenty of power and kept the flow steady the whole time. The kit comes with everything you need, including hoses, a bucket, and the non-toxic descaler solution, which made the whole process simple and convenient. Setup was straightforward and it worked exactly the way it should. If you need to flush or descale a tankless water heater, this kit makes it easy and the pump feels solid and reliable. Definitely a good buy! ⭐⭐⭐⭐⭐

Absolutely gobsmacked at how great this kit is! Flushing out the tankless water heat was easy enough, but to have everything I needed all in one space was wonderful. Everything was neatly packaged, and the kit came as advertised. The hoses were of high quality, and there were no leaks on either ends of the connections. The pump itself was brand new in box, and was quiet and powerful. I appreciated having the descaler in powder form as it makes it much easier to store and cleanup after use. The instructions were simple and easy to follow and while this won’t ever be my favorite chore it’s certainly one I won’t be putting off either.

This kit paired with a gallon of qeikdescaler is THE ONLY WAY TO GO This pump is very strong. I'm the instructions they include a breakdown of the pump and replaceable parts. Amazing. Thank you Superior!

Easy to follow instructions. First flush after using my heater for 1.5 years. So didn’t see big pieces of debris in the flush water but huge amounts of little white specks. Quality equipment. If you need to flush your heater - get this one - reasonably priced.

Easy set up and worked as described. Pump HP adequate.

This is compact and easy to use and saves hundreds of compared to having g plumber

I followed the Rinnai hot water heater's flush instructions... and the instructions on the pump's plastic bucket container... and I took my time doing every step. I did not force any valves open or closed. My Rinnai unit is 3 years old and this was the first time I tried to open/close valves, and they were all stuck. I removed the plastic caps on the valves, and I used a really small adjustable wrench to delicately open/close valves without the caps (meaning, I applied very little pressure on the wrench to open/close valves), and that worked. In the end, everything worked perfectly. No spills. No damage. Before I started the process I cleaned my Rinnai water heater's water filter, and I did that again after the flushing. The flushing actually caused a bit of gunk to get caught by the water filter, and so I'm happy I cleaned it before and after the flush. Based on the reviews for other pumps, it sounds like these pumps frequently fail in the near future (next few times they are used), and so I'll update this review after each flush to let you know how long these pumps last. I'm going to flush my hot water heater once a year. Going forward, I'm also going to toggle (on/off/on, off/on/off) my water heater valves once every 6 months to reduce the chances of them sticking again in the future. When I was done with my water heater flushing, for about 30 seconds I then ran fresh clean water thru the pump that exited into an outside drain. I'm hoping that will prolong the life of the pump. Meaning, I ran a garden hose to the bucket to fill it with clean water, while I simultaneously used the pump to pump the clean water from the bucket to a drain using a second garden hose.

Great kit containing everything you need to descale tankless water heater. It costs less than a single vendor service call to complete the descaling. Very highly recommended.

Fantastic product ,price and shipping ..worked like a charm
