Why are there air bubbles in fluid from Graco Water Pump?
If you notice air bubbles in the fluid of your Graco Water Pump, it could be due to several reasons. The suction line might be loose and needs tightening. Alternatively, the diaphragm could be ruptured and require replacement. Another possibility is a loose inlet manifold, a damaged seal between the manifold and seat, or damaged o-rings; in this case, tighten the manifold bolts or replace the seats or o-rings. A loose diaphragm shaft bolt or damaged o-ring could also be the cause, requiring you to tighten or replace the bolt or replace the o-ring.
Why does my Graco Water Pump operate erratically?
If your Graco Water Pump operates erratically, several factors could be responsible. A clogged suction line could be the issue, requiring inspection and clearing. Sticky or leaking check valve balls might also cause this problem, and you may need to clean or replace them. A ruptured diaphragm could also be the cause, requiring replacement. Finally, a restricted exhaust could lead to erratic operation, and removing the restriction should resolve the issue.
What to do if Graco Water Pump will not cycle, or cycles once and stops?
If your Graco Water Pump will not cycle or cycles once and stops, several issues could be the cause. The air valve may be stuck or dirty, requiring disassembly and cleaning with filtered air.

Overpressurization could also wedge the check valve ball into the seat, in which case you should install a Pressure Relief Valve. Lastly, the dispensing valve might be clogged, requiring you to relieve pressure and clear the valve.
