What to do if my Graco Fire-Ball D has erratic operation?
- RRichard PettySep 3, 2025
If your Graco Water Pump is experiencing erratic operation, it could be due to a couple of reasons. One possibility is an exhausted fluid supply; in this case, refill and re-prime or flush the pump. Another reason might be a held open or worn intake valve or piston packings, which would require clearing and servicing.
