Question DetailsAsked on 9/21/2017

water well.. low pressure and then normal pressure and dirt

after running water for about 15 minutes all air and dirt escapes and clean water returns (with fine bubbles in water) . after about 5 minutes of running water pressure drops almost to nothing but soon recovers to normal. when normal pressure again there is some dirt but not alot every time. sometimes there is a lot of mud in the tub. but it does clear up somewhat.could this be the pressure (bladder) tank or the check valve?

Sorry to say this, but unless you have a LOT of sediment buildup in your pressure tank or staorage tank so it is blocking the outlet intermittently as globs of it move into the piping, sounds (because of the mud) like your well is going dry or the pump is down in the bottom of the well - could be because of low water inflow either due to drought or blocked/ encrusted screen, the screen and gravel pack have failed so are not preventing fines migration from the surrounding soil so your well is sedimenting in, the cable or rope holding the pump and riser in the well has failed so the foot valve is down in the bottom sediment, casing failure or separation is letting soil in, surface sediment washed into the well in flooding and the pump is pulling that in - lots of possible causes.


You need a Wells and Pumps contractor to check out your system - probably about $250 diagnosis charge unless a deep well (over about 50') or has fixed riser (as opposed to flexible tubing which can easily be pulled) in which case can run to $500-1000 range pretty quickly. Simnple issues can commonly be remedied in same visit.
