Thanks. Sounds like the better way to do it.

I mixed them in a pail with water; first water, then vinegar, then bleach.

An update: shocked the well again. This time 4 gallons of 6.25% bleach as last time but also with 8 gallons of vinegar this time. To my great surprise, the flow rate is now off the scale on my flow meter. Meter tops out at 20 gpm. WOW!! Started out before the first shocking at 10-11 gpm max...

I will add vinegar next time I shock in a week or two. Will do the flooding thing next spring. Down to -2of last nite Thanks

He called today and suggested another shocking maybe with 50% more bleach.

Just an update. Latest well test shows static level of 65ft and draw down to 87ft after running 10gpm for 2 hours. So not a well yield issue. Also shock chlorinated with 4 gallons of bleach poured down the well and left standing for 48 hours. Lots of red residue pumped out. Well is now pumping...

Sounds like a very good analysis. Thanks Valveman. Especially the part about higher RPMs causing faster buildup: known phenomena with iron bacteria growth. Maybe that's why regular pumps with slower speeds lasted longer before....but ultimately failed due to too many cyclings because of heat...

Measured static level today but only after a 2 hour pump rest. It is at about 65ft. So not far from the 50ft or so I measured 10 years ago and that was in summer. Pump is at 180ft. Tomorrow I will measure draw down and shock the well.

That sure sounds like iron bacteria. Forms a brown sludge in bottom of toilet tank. Like a very slimy gel. Awful stuff. And it stains. Proliferates in running water. Will make hot water e.g. shower water smell a bit like sulpher. I keep my hot water tank at 160. That kills the bacteria so my...

Is the iron you are talking about iron bacteria or iron suspended in water? Mine is definitely iron bacteria.

Definitely iron bacteria!!! Probably unlikely it clogged impellers but worth a try. I get lots of iron bacteria sludge and its always been an issue.

Just spoke to my pump installer. He said there is only one check valve and its at top of pump. S that should rule out a pipe leak. Suggested I try and check what static level is . I will drop in ice cube and count time to splash. He is thinking the impellers may be clogged up with iron bacteria...

When I did this test, I inadvertently had all the taps turned off, so no flow. Pressure tank was still connected. CU301 controller was completely bypassed. When I saw the relief valve start to leak and pressure gauge was at 100 and still seemed to be rising , I rushed to turn off the pump...

Checked to see if I have a check valve in the basement and attached below pics of what I found . I suppose this could be a check valve although there is no arrow anywhere on the body to indicate flow direction. I would expect all check valves to have an arrow.No markings except country...
