After all the travails of the last twenty four hours with the lift station, Jerry had to throw up his hands and call for help. He called PEECO as soon as they opened this morning. Steve told him it sounded like a one way valve was open. He said it is about the size of  a softball and buried somewhere along the line. Jerry asked me if I could recall from twenty years ago just where the valve was buried. Not a chance. Jerry started digging. He located the valve fairly quickly. The valve had a swinging trap door about the size of the silver dollar that had detached itself from inside the valve. Jerry had just the right wrenches to open the thing up and replace a small bolt and nut to allow the inside piece to swing freely. He reassembled everything and was so pleased that everything is back to normal. He saved us a big bill from PEECO had they needed to come out.
