QwikProducts QwikDescaler+ (Gallon)

Second time using this product. Seems to work fine.

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.

Seems to work, but how do you know for sure? I flushed my unit for about 2 hours and fluid had turned orange. Not much in the way of mineral buildup. If I could see inside the heat exchanger I would feel better about the whole affair. I like to see a skull and cross bones on the label so you know it’s probably good stuff. This is non-toxic so who knows…?

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.

Thus is my first time i used this product. I have tried 4 other products that cost much more . It seems like a good product. Even shows when you need to add more by a color change. I let this run for hours and my tankless water heater and needed it. I had to add extra product after about 30 minutes of use. I knew because it changed from pink to yellow. Due to the six months since my last descaling. This cost me less and I have some for my next time. So double the savings. I will reorder this next time and every time after. It even worked better then 90% vinegar with none of the smell.
