Do you think the pump failures are due to design/manufacturing problems, or not flushing them out every night?
I have a MultiSprayer on the way, and was wondering if any amount of preventative maintenance would be enough to prevent a pump failure.
Are you using solvents that might weaken the seals? Or just normal Encap, protector chems?
These can be rebuilt, right? A couple of years ago I found some vitron seals for a pump rebuild kit that looked as if they might hold up longer than the Silicone seals in the factory setup....
