To follow up on my previous post. As mention previously, best way to remove old valve is find a straight section of the black 3” pipe. On mine it was about 10”. (2014 2552). Saw the pipe keeping as straight as you can as close to the middle of the run as you can. Mine was on the down stream side of the valve. Remove the 4 bolts holding the valve in place and the motor frame(if you have electric valves, and tie it up, or it will swing down and HIT you in the face!). The afore mention 3” fernco rubber connector is about 4.5” long. It gives you lots of lateral adjustment when you put things back in place. Saw off another 3/4” off the 3” pipe(the one that comes off when you remove the bolts), this will give you plenty of room to slip in the new valve. Slip the rubber connector over the 3” black pipe still attached to the stack as far on as you can. Using Vaseline, “glue” the new rubber seals onto the valve. This helps holding them in place while you slip the valve in. Line everything back up and slide in place. With the 4 bolts loosely tightened, slide the rubber fernco connector back and centered on the 3” black pipe. Tighten everything back up.Adjust the electric closer for full travel and good to go.
