Total Chlorine Test Kit with 10 tablets -TK-CL-10-KIT

For anything to do with my RO/DI system, this is the place to go. Everything I've ordered so far is high-quality, a fair price and is shipped quickly.
The 3-way ball valve is well-build and functions just like it's supposed to, and should last as long or longer than the rest of my RO/DI setup. Would definitely order another of the same thing if I need it.
