I have my own well. The pump delivers water in to a rubber bladder tank, which provides pressure to the house.
Recently, the cold water pressure dropped quite a bit. Its still usable, but definitely lower than it should be.
The local water guy came and tested the system, and told me I need new pressure tank. The existing one was about 4 years old.
He came along a fitted a new tank, but the problem was resolved. The pressure in the house was still low.
He then deduced that the problem was the well pump, which because we have a very deep well, he estimated would cost €1500 to replace. The existing pump is at least 10 years old (installed by previous owner, now sure when).
I don't really understand this. My understanding is that the pressure tank provides pressure, not the well pump ie I fill the bladder with air, water flows in from the pump, compressing the air until the pump cuts out, I turn on the tap and the compressed air forces the water out.
The well pump is delivering water into the tank, so I don't understand how the well pump can be the issue. I am little bit dubious about the guys advice, given that he wasn't able to work out that the pressure tank was working fine in the first place.
I would have thought that once the well pump can deliver water into the pressure tank, that achieving pressure is just a matter of getting the air pressure in the tank slightly lower than the cut off pressure for the pump?
Advice?
