Review on 💧 FloodStop FS 3/8-C v4: Enhanced Water Damage Prevention System for Dishwashers, Toilets, and Water Filters by James Fisher

This valve works as promised but the outlet side of the valve body is not machined for a compression fitting. So only a flexible hose can be connected to it, which is not as tight as a solid copper line. This design flaw was not listed in the description. Also, the kit I received included instructions for installing and using a different model of FloodStop check valve. Luckily, this device is easy enough to set up for anyone with modest plumbing experience that no instructions are required.
