I would consider a pump with variable rate - it won't start/stop frequently and does not need an accumulator. Jabsco and Sureflow both have a model.

Actually the pressure switch. It still pumps fine but without the switch to shut it off it trips the breaker. Pump is a PAR / ITT JABSCO 36970-1000, 2.8 GPM. Has been out of production for years. Some internet search show a switch 37121-0010 is supposedly available on flea bay for about $60 plus shipping. Supposedly OEM part that has been sitting on the shelf for years. A brand new pump assembly is less than $150. Given the age of the current pump, a new one seems to make sense. That gets us into the tubing which is Qest, is also OEM and there is a small leak that so far has eluded discovery. The new pumps do not provide fitting compatible with Qest. One of my options would be to replace the tubing especially with the new plastic tubing now available. Any thoughts on which system works best?
