Check Valve for Single Handle Ceramic Cartridges

 

  • Pressure Balancing: In single-handle shower and bath faucets, check valves help maintain a consistent temperature by preventing sudden pressure changes.
  • Cross-Flow Prevention: Prevents water from a high-pressure line (e.g., cold) from flowing into a lower-pressure line (e.g., hot) when the faucet is off.

“This place rocks! I have replaced two parts for an old Gerber faucet in the laundry tub. After the spout was leaking, I could not find the right washers anywhere. I had to replace the whole spout, which they had in stock, and it was priced competitively. Now, not a drop leaks. ”
