Ace Pumps
The Ace pump is designed for long life and service.
Through the years, it may be necessary to replace the
mechanical seal or service components of the pump. A
mechanical seal may weep slightly, but if it starts to drip,
the pump will have to be disassembled. Before
disassembly, be sure to wash it out with fresh water.
If the pump leaks, before removal from sprayer, run the
pump with adequate water in tank to diagnose the actual
pump problem.
