hi all
I have a 2" well it is 2" pvc casing 100' feet deep with 5' of screen the static water level is 65' from bottom. this well was drilled in 1986 it is only used in the summer a for water source heat pump for a/c, the waste water is used to water the lawn and garden. it has had several mismatched pump and jet assemblies over the years but has always pumped around 3-5 gpm the jet had not been changed just several different pumps of varying hp. this year I replaced the pump ,jet assembly casing adapter and drop pipe. the pump is a goulds sj10 the packer jet assembly is a FP2B-50 with a #13 nozzle and AD724 venture and a AWD2 casing adapter.the drop pipe and tail piece are1 1/4" npt poly. the jet is set at 50' with a 34' tail and a 5' 1 1/4 " screen attached to the tail. the foot valve is at the jet assembly. when I first primed and started the pump it primed on the firs try and was pumping about 12 gpm. it ran like that for about 24 hours the it would hardly pump any thing at all the pump back pressure was set at 40 psi the gage would fluctuate up and down when it was not pumping much water. i then installed a globe valve in the discharge line of the pump to restrict flow and it finally started to pump again at about 4 gpm it worked like that for about a week and then quit pumping again, I pulled the drop pipe and jet to see if anything was plugged up nothing was, measured static water level still 65'. is it possible that the 1 14/ screen is getting plugged with sand and falling off when I pulled it up? or should the foot valve be at the bottom of the tail piece and not at the jet?
thank in advance for any help and advice
