Just purchased a Everbuilt THD1020 (In-Line Sump Pump Check Valve) , and installed in the back hose of our washing machine. The original hose would leak detergent soap and water. Is it a good practice to install In-Line check valves like this on washing machines? Are there any negative consequences, issues with flooding or clogging from doing this? The original hose kept leaking, so decide to get this instead. How does this fit in state california rules?
