QwikProducts QwikDescaler+ (Gallon)

Been living at our place for almost 2 years. Not sure when the heater was last flushed so rather than using vinegar I opted for this. Considerably more expensive but the reviews were good. bought the kit that had a pump, hoses and pail on Amazon so i knew all connections would work. Proly cheaper to buy the components, but piece of mind counts for something. Connected everything and I mixed the descaler 3:1 ratio and let it run. Foamed in the beginning a little, and I assume that is the calcium reaction. Now recommended time seems to vary so I let it go for 2 hours checking every half hour. At the 2 hour mark the solution started to change colour, which tells me the long cycle was correct. I mixed up a second batch and ran it for another hour, but no colour change. While I did not see any significant change in water flow or pressure at the tap, the colour change was enough to show me this worked. I will use this product again when I flush.

This stuff did a great job descaling my hot water heater. Went from pink lemonade to black cherry quick. Resolved our issue with descaling the heat exchanger and after we cleaned the bugs out of the squirrel cage the Code 10 was gone. Seems like a great product. A jug goes a long way at a mixture of 5:1.

Second time using this product. Seems to work fine.

Worked as advertised. Buying on regular basis now.

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.
