Shallow well sears jet pump w/pressure tank
in basement. 30' well and 15' horizontal run to
same. VERY mineral rich water. When the pump
kicks in it sounds like its straining a bit
lately. Im thinking I should pull the pump,
dismanle it and clear what Im guessing are
serious mineral deposits.
Any thoughts on the matter?
Definitely not dry well or sucking gravel
30' deep x 3' diameter. water table is about
5' below ground level (lakefront propty)
The "dip Pipe" is about 5' above the bottom
of the well. Well only ran dry once a few
years back due to a "running" toilet for
2 days straight, and even then it came back
up within a few hours..
I don't think you described the noise, so it's hard to guess if it is
due to pump wear but.... since you suspect something is blocked, it is
probably the foot valve screen in the well. Biomass or scale buildup can
do that. If you pull it you might want to cut off 2-3' of the drop pipe
to prevent it happening soon. The best would be to clean the bottom of
the well if you see any evidence of biomass.
You can get a feel for the blockage by the time it takes the pump to
build up pressure and shut off. Normally it shouldn't take much longer
than 2-3 minutes max. If it's longer than that, then the pump can be
worn or you have a blockage. This assumes that you aren't finding air in
the water which says the pump is sucking air due to a leaking fitting or
