I have an old myers well. The pump stops running whenever it gets ready to. 2-3 days later, maybe sooner, it comes back on and we have water again. The casing is beside the tank with feed line going into well coming out of the top. Of course it's galvanized. How do you get to the pump? I've tried to take the casing up. I took the 4 hex head bolts out, disassembled the feed line but it seems that the pipe is going to fall in if you remove the cover. Do I need to tie it off before removing the cover?
