Review on 🐋 Whale LV1219 Non-Return Inline Valve for ¾-Inch and 1-Inch Pipes - Nitrile, Black by Steven Hanson

Inline check valve works as promised! I have used it in my boat's sump pump and it prevents backwashing and allows pumped water to exit the boat when needed. This can be a problem in my setup as the external outlet line is above the level of the sump. I am satisfied and will buy another valve if necessary. It does what it's supposed to and isn't too big for most setups.
