  If your VERDER Water Pump will not cycle, or cycles once and stops, it could be due to a few reasons: * The air valve is stuck or dirty, disassemble and clean it, using filtered air. * The check valve ball is severely worn and wedged in the seat or manifold, replace the ball and seat. * The pilot valve is worn, damaged, or plugged, replace the pilot valve. * The air valve gasket is damaged, replace the gasket. * The check valve ball is wedged into the seat due to overpressurization, install a pressure relief kit. * The dispensing valve is clogged, relieve pressure and clear the valve. * The air tubing is plugged (remote air control models), clear the tube.

- L
  Larry LewisSep 7, 2025
  If your VERDER Water Pump cycles but will not prime, it could be due to several reasons: * The pump is running too fast, causing cavitation before prime, you should lower air inlet pressure. * The check valve ball is severely worn or wedged in the seat or manifold, you should replace the ball and seat. * The seat is severely worn, you should replace the ball and seat. * The outlet or inlet is clogged, you should unclog it. * The inlet or outlet valve is closed, you should open it. * The inlet fittings or manifolds are loose, you should tighten them. * The manifold o-rings are damaged, you should replace the o-rings.
