Review: Easy to use, work fantastic. - Simple to use - works fantastic Review: Fast and Easy to Use - I bought the Pentair test kit to test my household well water. Although I have a softener, it is around 10 years old and seemed to have quit working. The kit confirmed my suspicions. My water supply was extremely hard. Once I repaired the softener I tested the water again. Again, the kit confirmed what I already knew -- my water was soft again. To test water one just fills the clear plastic bottle with water to the indicated level. Then, add 2 drops of the blue liquid and swirl the container. Next, just add one drop at a time of the clear liquid until the water turns blue. If the water is blue without adding any drops the it is already fairly soft. Otherwise, the number of drops required to turn the water blue correlate with the parts per million (ppm) of hardness in the water. The instructions include a simple math formula for converting the ppm to grains, which is what most water softener specs refer to. No, it's not super precise. It can't give you a specific reading on the exact hardness of a particular sample. Still, it is very useful for selecting or repairing a water softener. Even though this is sold as Pentair, it is also branded as a "Rainbow" test kit. Apparently, aquarium owners use it to check their fish tank water.

A ### ⭐⭐⭐⭐ Did it job *by B***W on December 4, 2013* Great product. Should also advertise that you can use it to test your water softness not just for pools. Just say'n. The reason for the 4 stars is the blue liquid was about 1/4 gone because it was not sealed correctly and leaked all over the inside of the package. But otherwise good. Should ship in a box not envelope. ## Frequently Bought Together - Pentair R151276 1200 Total Water Hardness Test Kit - Varify Water Hardness Test Kit - Water Testing Kit for Home, Drinking, Well, Spa, Swimming Pool, Softener, Dishwasher & More - Hard Water Test Strips for Calcium, Magnesium etc (0-425 pmm, 150 Strips) - JNW Direct - Quick & Accurate Hardness Test Strips - Ultimate Water Hardness Test Kit - 150 Strips with eBook --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/1097769-pentair-r151276-1200-total-water-hardness-test-kit](https://www.desertcart.sk/products/1097769-pentair-r151276-1200-total-water-hardness-test-kit) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-09-15*
