Erratic operation of your Graco Water Pump can stem from several causes: * A clogged suction line: Inspect and clear any obstructions. * Sticky or leaking balls: Clean or replace them. * A ruptured diaphragm: Replace the diaphragm. * A restricted exhaust: Remove any restrictions.
Why does my Graco Husky 1590 Water Pump exhaust excessive air at stall?
Excessive air exhaust at stall in your Graco Water Pump may be caused by: * Worn air valve block, o-ring, plate, pilot block, u-cups, or pilot pin o-rings: Repair or replace the worn components. * Worn shaft seals: Replace the shaft seals.
Why is my Graco Husky 1590 leaking fluid externally from the ball check valves?
External fluid leaks from the ball check valves on your Graco Water Pump can result from: * Loose manifolds, a damaged seal between the manifold and seat, or damaged o-rings: Tighten the manifold bolts or replace the seats or o-rings.
Why Graco Husky 1590 cycles at stall or fails to hold pressure at stall?
Pump cycles at stall or fails to hold pressure at stall because of worn check valve balls, seats or o-rings. Replacement is needed.
