Hello all - this is my first post here, as I've never had a great deal of interest in wells, pumps, etc. But now I've got "well issues", so it's my new favorite topic!
Anyway, I live in Maryland and have a well that produces about 4.25 GPM. I've got an 8-year-old 1/2 HP Jacuzzi jet pump and a 20 Gallon pressure/holding tank. I've owned this house for about 10 months and the water has always been VERY clear, odorless and tastes fines. I've also always had at least decent water pressure as well. Recently, however, I've had issues with water pressure and sediment in the water (a LOT of sediment). I had the sensor switch replaced, but the jet pump is moving pressure up to about 45 psi once it switches on and runs and then immediately dropping to about 25 psi when it switches off (just a few psi above the "switch on" setting). The thing is also running much longer than normal, leading me to believe it's "overpumping" and stirring up the sediment.
Anyway, I've been told that there is a worn valve that's allowing pressure to escape, as it were, and that replacing the pump and plumbing is better than simply fixing the valve. I'm fine with that, because I've heard that submersible pumps are generally preferred and I'd like to upgrade from the 20 Gallon Amtrol tank (WX-202) to the 44 Gallon (WX-250).
Finally - my question...would it be recommended to simply go with a constant pressure submersible pump, or is the standard submersible/pressure tank suitable? If the constant pressure, what would the recommended HP be? I've seen 1 HP recommended, but might that be overkill for a 4.25 GPM well?
For more background - I live in a house with 3 bathrooms and also have a dishwasher. 2 people live in the house.
Any advice, answers, musings, etc. are quite welcome!
Thanks in advance,
