I've been trying to disconnect this pitless adapter and cant figure it out.It has a pivoting leg that holds it up to the well casing but the leg has no cable. I made up a hook and tried to pull it up with no luck.Then I tried to push it down, still no luck.How in the heck do you get this thing to release?I have a leak or a bad check valve and my electric bill is killing me.Thanks for any info,Gary
