When ever we hose or try to wash car if we continuously hose for like 2 0 min we loose the prime on our well. Why is this and how can we fix it as its very aggravating. Our well is 80 feet.:(

At first I thought it might have been a faulty check valve but not if you lose pressure when pumping.
Larger pressure or storage tank would help. You might be pumping down a lowered water table if the pressure and volume suddenly drops and you lose prime. If you run out of water to pump that's what happens. When you get repaired let us know what was wrong. Good luck, Tom

After twenty minutes solid, might he be pumping the well dry?

You can install a large bladder tank and that will give you more water storage,more pressure,longer drawdown before the pump kicks in to satisfy the pressure switch.

You can also install a submersible pump and the priming is history. Although the submersible pump in the well can pump 10 gallon per min . Then a low water cut off pressure switch should be added to help save the pump from running when the water level drops below the pump. The 80 ft deep well hopefully has a good recovery.

A new fiberglass 100 gallon storage tank and a v60 bladder style tank would give you great results along with a submersible pump installed.

Good luck lets us know how it goes.

If you pump into a 100 gallon storage tank, you will then have to repump into the pressure tank... two pumps.

Not if you install the 100 gallon tank in line with the bladder tank and use a check valve.

If you do that, how will that not result in pressurizing the holding tank (which is not a good idea)?

Fiberglass,composite PRESSURE TANKS made by Wellmate 80 gallon and 120 are used where water is corrosive and reacts to galvanized tanks.

These are used for treatment,retention etc...

I have replaced many galvanized pressure tanks that have weep holes(leaks from rusting inside} Google Wellmate for more info.

Just trying to help!! Check it out.

Now that makes sense. Your first reference was to a "new fiberglass 100 gallon storage tank". That struck me as a holding tank. Just a misunderstanding.
