Greetings everyone:
I have a 156 ft steel cased well with pitless that was drilled in 2004. Static water level was 101ft, air test was 40-50 gal minute. I'm not sure what the current pump is, all I know is the control box is a Franklin 2HP. I have a 86 gallon pressure tank on a 60/40 switch which takes about 1 minute to fill, so math leads me to believe it's a 20 gpm pump. The well provides water to a 3 bed 2.5 bath house and shop with 1 bath and sink. I want to pull and replace the pump because I'm getting water hammer on pump shut off (been happening for years and i'm getting fed up with it), which from research indicates the check valve is bad. I'd also like to install a CSV when I pull it so I can water the lawn with sprinkler system and not destroy the check valve. I stuck a camera down the well and it looks like PVC pipe on the end of the pitless, which makes life difficult for DIY. Also the pitless is very corroded with tons of build up around it and lots of leaking down the pipe; looks as if there is a leak somewhere..I don't lose pressure so not sure whats going on. Video is linked - going up the pipe and at the end you see the pitless adapter.
I've been looking at Grundfos pumps with soft start specifically because I lose power a lot and the generator would like the soft start of the Grundfos SQ series. Looks like these are 2 wire and my current setup is 3 wire. So I think just bypassing the control box and capping the neutral at the well head would work.
Any suggestions? Pull pump and replace? New pitless? Use poly or new PVC pipe? Pay some to do it (Any recommendations for south Seattle/Tacoma area? I currently have a CSV1A sitting around but i'm reluctant to install it do to the piping under the house. I'd rather put in a CSVS125A in the well itself.
Thanks for replies.
