Review on ⚗️ Cobalt Chloride Test Papers: Accurate Strips for Easy Testing by Lild Zimmerly

There was a tap water leak in our new house that we have been trying to find for 7 months. The builder couldn't find it, the plumbers couldn't find it, and we couldn't. I ended up ordering these strips and glued them along the lines where the water was collected in the bucket. At this point there were several connections. After 3 days I finally figured out which line was causing the problem as the blue turned light pink. No more leak! I would have given 5 stars but the strips were so small it was very difficult to work with in a confined space!
