Pulling a submersible - not sure if this is right
OK I'm a little green at this so please forgive any ignorance on my part. I've gone through all the checks for low pressure issues and now believe that I need to pull the submersible for some checks. I'm using a 1/2 ton electric hoist to pull up but it's not moving. How much lifting power is needed? am I doing something wrong? do all submersibles have the same pitless adapter which requires a straight pull up or is possible the pipe needs to be turned/unscrewed?
