If the Graco Water Pump operates, but the output is low on the up stroke, the fluid piston valve or packings may be held open or worn. Clear or service them.
Why does my Graco Water Pump fail to operate?
If the Graco Water Pump fails to operate, several factors could be at play. It might be due to a restricted line or inadequate air supply, in which case you should clear any obstructions and increase the air supply. Alternatively, there might be insufficient air pressure, or the air valves are closed or clogged. Make sure to open and clean them. Another reason might be exhausted fluid supply. Refill it and purge all air from the pump and fluid lines.
What to do if my Graco Water Pump output is low on both strokes?
If your Graco Water Pump operates but the output is low on both strokes, consider these potential causes: a restricted line or inadequate air supply (clear any obstructions and increase air supply); insufficient air pressure or closed/clogged air valves (open and clean the valves); exhausted fluid supply (refill and purge air from the pump and fluid lines); or a clogged fluid line or valves (clear the clogs). Also, check if the packing nut is too tight (loosen it) or too loose, or the throat packings are worn (tighten the packing nut or replace the throat packings).
Why is my Graco Water Pump operation erratic or accelerated?
If the Graco Water Pump operates erratically or accelerates unexpectedly, first check if the fluid supply is exhausted. If so, refill it and purge all air from the pump and fluid lines. Also, a held open or worn intake valve, a held open or worn fluid piston valve or packings might be the reason. Clear or service them.
What causes low output on the down stroke of my Graco Water Pump?
If your Graco Water Pump operates, but the output is low on the down stroke, the intake valve may be held open or worn. Clear or service it.
