I didn't read all 90+ posts, and I'm not a well expert. Just 68yo diy'er growing up on a hand dug 40ft well on a farm, 2 springs and a 2ac lake. Underground well house, couple miles of pipes going everywhere, two houses, both springs and lake.
1) did you check tank to meter pipe?
Imho there are two separate things: pressure and volume. Here (80 ft well, Goulds 3/4hp pump) we have good pressure, low volume.
2) what is your volume?
Here we can draw about 35-40 gallons continuous at one time at about 50psi...then that's all she wrote. Wait 20 minutes and repeat.
Wife just now used water, shut it off, I filled a 5 gallon bucket. Well pump ran soon as bucket was full, ran for 12 seconds and shut off.
3) how old is your pump?
Pumps get weak. My 1/2hp pump I replaced with 3/4 Gould's was about 20 years old. (Yes, I know...3/4 is too big for 80ft well)...but man it works great. That 1/2hp was a generic one from Lowes. It acted exactly like yours. I noticed well light staying on longer and longer. I spent hours replacing pressure switch, checking everything, messed with pressure lowering it (bandaid approach)...finally replaced pump. We just had horse stable completed so I knew demand would be greater.
In 40 years here I've never needed 40 gallons of water all at once. We probably do use 100-200 gallons a day but space the demands out.
4) forget pressure. How's your volume? Before you ever had trouble, did you check it?
I filled a small above ground swimming pool here years ago no problem. At midnight I adjusted hose nozzle so it was maybe a gallon or so/minute...but that's 500 gallons overnight. Pump cycled on and off occasionally. In a few days it was full.
One last funny thing:
Growing up grandparents next door lived in a large 2 story house they had built in 1940. Grandad had a hydraulic ram in our creek (overflow from lake), ram was near a spring.
His house had a 2000 gallon water tank in the attic (it's still there, impossible to remove it). The hydraulic ram pumped spring water uphill about 600 ft away and maybe 60 ft elevation spring to attic tank.
His house everything was gravity fed from the tank. It wasn't efficient which is why he had well dug 6 years later. Two guys up the road, a dwarf and a tall skinny guy. Dwarf had a mattock and shovel with handles cut short. Well is 3 ft diameter, he would dig filling a bucket on a rope the skinny guy pulled up and dumped. They hit water at 35 ft or so, kept digging all he could. They used concrete pipe to line it.
Grandad fell through the wooden top once which is why today it has a heavy greenstone slab over it.[emoji2]
