Help with setting psi for pressure tank

[gkswets]

I have been in my house for about 7 months now. We have been having a steady flow of problems over the past 3 months. The system runs as followed:

Well with submersible well head pump with a pressure gauge and switch

40/70 in line to a air pressure tank

Then to a booster pump (can't find the HP), through a vent to release sulfur gas, through a check valve and into a large storage tank, probably around 150 gallons. There is a gauge on the top of the storage tank with a plastic line leading to a pressure switch set at 55/75

From here to a softener system and then to the house.

Our first problem was loss of pressure and water prime. The property management company hired a well contractor to fix the system. First they changed out the pressure tank, no help. Then the pressure switch for the well head pump, no help. Finally, they changed out the check valve. I'm not a plumber or well driller, but even I would have changed the check valve first. Then the booster pump would not come on and we were working off the pressure from the well head pump. I changed the pressure switch for the booster pump and that is working again.

First question is - The switch instructions said to fill the pressure tank to 2 PSI below the start pressure of the switch. Having a switch on the well side of the pressure tank and a switch on the storage tank side of the pressure tank, which switch do I base my PSI for the pressure tank?

And is the system designed correctly? I researched and found that most systems have the storage tank and the pressure tank between the booster pump and the water softener.

Sorry about being long winded, but I am through relying on others to fix this. I have the ability, but need a boost in knowledge to do right.

Thanks

??? Sounds like an engineers wet dream. Why all the tanks and that huge storage tank unless it is some sort of farming operation. Definitely not needed if only a residence.

Losing prime? You have a submersible. They do not lose prime unless the well runs out of water. Or do you mean the pump is on top of the well? That is not a submersible. It would either be a shallow well pump (one pipe down the well) or a Jet Pump (2 pipes down the well) - those can lose prime.

Also the pressures are way above normal for residence. 40/60 is about the max recommended _at the house_. You make no mention of elevation differences which could account for the high pressure settings.

Is it designed correctly? Can't say. I have never worked on a system that includes a softener in the ciruit so I don't know where that should go.

As for setting the pre-charge? You do that with the tank empty, air it up to 2psi below cut-in. That should be measured at the tank guage.

FWIW, ours goes submersible pump to softener to pressure tank to house. No booster, no storage tank.

Ignore Stormin Normin, the mad Mormon/Moron.

Your terminology is a little confusing. Is the well pump at the bottom or at the top of the well. IF it is at the top, you probbably have a jet pump . How you can release only the sulphur gas doesn't make much sense. Where are you located, what part of Canada or the USA, or elsewhere???
