The Manifold Primer, aka Water Trap, (MP) is a device positioned between a water pump being primed and a source of vacuum pulling the water.

The Diaphragm Primer has a flapper check valve in the diaphragm and a disk check valve at the bottom of the unit. Air flows through the bottom check valve on the diaphragm up stroke then through the diaphragm valve on the down stroke. Diaphragm is actuated through a connecting rod eyebolt attached to a fulcrum handle bracket. FEATURES:
