What's the causes for dropping high pump pressure?
Expert:  catmastertech replied 1 year ago.
Sorry for the late reply. I work in the Eastern US and have very limited time during the day. I answer more questions at night and will be available for a few more hours. I hope this is not to much an inconvenience.Worn pump or worn relief valves.Poor operator control causing overheating or DERATING.Improperly set calibrations or auxiliary setups.

I see you are posting multiple questions. I recommend you stick with one technician to solve this issue. It is not helpful for us all to spend time on one customer when we know only one will get an answer accepted. I will OPT-OUT and leave this question to the other tech.
