Dual Check Valve

 
Dual Check Valve Quantity in Basket: None
Price: $26.00
 
 
Quantity:
 

Dual Check Valve contains two internal check valves to prevent backflow (reverse water flow) through the pump into the potable water system. Although the pump design and recommended setup make it practically impossible, it may be required by local authorities.

No extra for shipping with the pump.
