Qwik Descaler+

Second year of using this product to descale my Navien NPE-180A2 unit. Year 1 of doing the flushes myself, I mixed up the necessary amount of solution per the dilution rates and followed the instructions for how to flush my system. In total, took about an hour with the flushing process being about 35-40 minutes. The amount of material this solution was able to remove. I remember seeing what the technician got out on the very first flush done on the system and I feel like this removed a lot more. Year 2 of doing the flushes myself, similar results and time it took to use. Extremely happy with the product and results.

Second time using this product. Seems to work fine.

Works great. This product saved me thousands of dollars! I used it to clear out scales from a tankless water heater that appeared to be beyond repair. We bought a new house with a tankless water heater and did not realize that we also needed a water softener until about five years later. Once we almost completely lost hot water, a repair man told me the only solution was to completely replace it for multiple thousands of dollars. I decided to ignore his device and using Youtube and watching him, I was able to figure out how to use this descaler and a small pump to clear out all the mineral build up. The instructions said not to go more than 30 minutes, but I did 4-5 hours for 3-4 different days. Each time the "hot" water got a little warmer. Eventually, I got the hot water to work completely. With our new water softener system and this product, I think I solved the problem. This product saved me thousands of dollars!

I've used three other products before this stuff on my Rinnai tankless water heater. The last product I used about 5 months prior and I was starting to notice issues so I suspected it needed a clean again so I bought this and it made a huge difference and foamed up a lot which led me to believe it was actually doing something too. My tankless has been running great for a while now... Touch wood.

Very effective product. I did not know to flush my tankless water heater. So we did not flush it for 5 years. This product removed almost all of the build up the first use. Easy to use. Safe to use too.
