Thanks Earl, when do you know the pump is no good. QUOTE]
Have to confess my method is pretty rudimentary. Pump Stops working, - replace - if new one works, old one is bad. If new one doesn't work something else is wrong.
With the quick connect fittings it's easy to swap the pumps and then un mount the old and re mount the new. The simple swap without mounting can save time if the pump still does not work and something else is an issue.
Earl, you don't have the quick-change mounts?
It's nice to be able to change out a pump while a customer waits.
