Update on the well situation:
I have been pumping it as much as I can and the yield has gone up slightly to around 8.9-9.9 gpm. However, it was as cloudy/sandy as ever and is not clearing up at all, actually had gotten darker and was pulling more dark brown to black fine particles.
Yesterday I pulled the pump and found the brand new stainless steel housing was already experiencing some minor corrosion on the outside of it. I raised the level of the pump 6 feet at the request of the driller to make sure it wasn't too low so now it is sitting at approximately 79-80 ft. in a 90 ft. well.
The driller had a different opinion on how to clear the well, he said I was overpumping it which was causing the sand to continue. He said since I have 40 feet of screen with a static water level of 54 ft I needed to pump closer to the yield rate of the well. He is willing to drill another well at no cost to me if I can't get this thing cleared up so that is a major positive!
I ran my hydrant at about 6-7.5 gpm all day yesterday and the well did in fact clear up in about 5 hours. Now it is roughly a teaspoon of sand/fines per 5 gallon bucket. Some larger grains but mostly just very small and not a lot.
I have a cycle stop valve from Valveman ready to install in my well but wasn't sure if that was too much sediment for the CSV. The driller suggests/highly recommends that I also install a 7.5gpm dole valve to limit the intake of debris. I am thinking that as long as I am careful with my water intake the only time that I would approach even 10gpm is when my Katalox unit is backwashing so I should probably be okay with just the CSV....Any opinions? Thanks so much for all the help! We are almost there! (ignore the black thing on the left, it blew in)
