Doug, I always appreciate your responses since they seem to get to the root of a topic with no BS. I have a new Shurflo 4048 pump that is cycling far more than I would think is proper. I see from the paperwork that there are adjustable bypass and pressure shut-off switches but can't really see them due to the installation position.
Can you say what tool, screwdriver, allen wrench, etc., is needed to make adjustments and which should be adjusted to overcome the cycling? Any insight will be helpful since unless I remove the pump for access I'll be working blind. Obviously I would prefer to make adjustments while connected rather than adjusting and reinstalling each time since the freeplay in the lines wouldn't allow any other approach.
Thanks in advance for any assistance you may be able to provide.
1. Allen wrench is used
2. The factory default settings is rarely at fault
3. Never heard of Bypass switches. But, Pumps have evolved over the years. Usually if you have to adjust the pressure switch cut off, that means the switch is slightly defective.
4. Shurflo calls the Pressure switch a BYPASS switch now. Same thing. Doug
