How do check valves compare between manufacturers?

• Check values are one-way valves allowing water to pass up through a 'gate' (within the check valve chamber) as the pump pushes the water up the discharge pipe.  When the pump shuts off, the water that has not been removed from the discharge pipe will by gravity be pulled back into the sump pit unless the check valve gate is there to stop it. 
• The connection of the check valve to the discharge pipe varies by manufacturer.
• • Campbell uses a 'True Union'.  Two cemented connectors are screwed on each end of the discharge pipe between which the check valve will be placed.  Then each end of the check valve connection is screwed into the discharge pipe connectors.  An O-ring seals the union.  This provides a very tight fit.
  • Little Giant, Wayne, Zoeller, Basement Watchdog and Flotec and Pasco check valve connectors slip over the discharge pipe. Clamps are screwed over discharge pipe and valve connector ends and tightened to prevent water from dripping out. 
    
• The material used for the check valve chamber varies by manufacturer
• • Zoeller 30-0151 is made of cast iron.
  • Little Giant, Wayne, Basement Watchdog, Zoeller 30-0181 and Zoeller 30-0021, and Pasco 29121 are made of strong plastic.
  • Campbell uses clear PVC so the movement of the water is visible.  This aids in determining if the pump is performing properly.
• The type of gate used varies by manufacturer
  • A flapper gate is used by Little Giant, Flotec, Wayne, Zoeller, Basement Watchdog and Pasco. A flapper gate is a single moving plate or sealing disk suspended from the top of the valve body.  It can swing in only one direction for water flow. It relies on the flow of gravity to help swing the valve closed with the back flow of water pressure. If the water attempts to flow backwards, the flapper will swing closed and seal the opening.
  • A spring loaded gate is used by Campbell. The spring loaded gate uses a heavy-duty spring to securely close a single disk.The disk can only be opened only by the force of water overcoming the closing tension of the spring. When the pump shuts off the spring automatically closes the valve preventing the back flow of water into the pit. 
• The closing noise of the gate depends upon the design within the chamber.
• • The Campbell B-0823-15 "Brady" Quiet Check Valve 1.5" - White. 
  • The Little Giant, Flotec, Wayne, and Zoller, flapper gate are most noisy.
  • The Basement Watchdog (Glentronics)  KCV check valve compensates for the noise with an added air chamber.
