I don't know about having warm water....mother earth is a pretty constant 52 degrees here in Ct so it would take A LOT of energy to heat the old girl up.
First thing I would do is pull the pump up a bit and pressure test the pump and down hole piping. If you have a hole in the pipe or a leaky check valve, the water will run out of the pipe. If the pump is worn out, it won't make pressure.
I'm afraid to pull the pump, maybe I'll jog something loose and have a major problem costing me thousands.
I't working now but I have to keep a check on it, I'm thinking the reason probably is a small leak If so, it probably will get worse over time, or can a partially clogged filter screen in the well lesson pump efficiency? And the answer to your question, the water does stay ice cold, I did find out that water heaters for a family of (2) cost around $45 dollars to run.
Thanks for responding!
This was a reply to another member:
I checked it yesterday, one time it took 2 minutes, the second time 1-1/2 minutes.
When the water is not used, the pressure does not drop at all.
At the time I purchased the property, I was told it was around 175 feet, I'll drop a nylon string with a weight and get back to you on that.
We only use the shower 3 times total per day, flush the toilet maybe 10 times, use the dishwasher sometimes 2 times a week, and don't water the lawn, only the flowers in the summer.
The cut-on pressure has remained at 30, while the cut-off pressure lessens as I turn the nut counter-clockwise,
I've done that twice, the first time I change it from 50 to 48, then from 48 to 44, to allow the pump to shut off.
Perhaps I didn't turn it enough the first time, maybe I should have purchased a 20-40 switch instead of a 30-50 when I installed the tank.
I take it that the reason my yard hydrant doesn't work until I run an outdoor spigot or flush the toilet, is because of the check valve at the tank. And I take it that a good working check valve at the tank is why the pressure doesn't drop, and prevents me from detecting a leak past the tank.
So far with the cut-off at 44 psi, it seems to be working OK, I'll have to keep a check on it for a longer span of time.
I got my electric bill yesterday, it was much lower 641 kwh, but during the last month the pump was working differently as I was changing the cut-off setting. If it stays fixed, maybe I have an even lower bill. Do you think it's OK to have the setting on 30-44, or should I investigate why it has changed, or am I just opeing a can of worms? I calculated that if the kwh stayed at 14.5 a day, and the pump didn't decide to run longer again, I would be down to about 450 kwh per month.
