Black tank valve…installed
« on: October 15, 2021, 02:38:24 pm »
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.

Let me make sure I understand this. You cut your pipe just to change the valve? Is there something different on the 2014 model year?

Yep!  Absolutely no slack to slip out clogged valve.  Crawl under yours and take a look.  Takes a can of silicone spray with you to lube the adjustment screws if you have electric sliders.

I have no idea what they did between 2010 and 2014,  or if there is a difference back there between the 2551 (mine) and a 2552, but when I had to replace my black valve I realized it was necessary to remove the macerator bracket and loosen the whole drain setup. I went ahead and put in both new valves and actuators. It really wasn't that hard...no need to cut or compromise anything.

Mines a 2011.   2552.  I changed my black valve in about 20 minutes.  Used a oil change pan to catch the quart or so of water in the pipes.  I carry an extra valve just in case I have one that won’t close all the way once again. I could change it out in 20-30 minutes in a parking lot.

Boy oh boy, that is surely an understatement.

A worst case scenario, try making this fit like a glove.  Paper and cardboard patterns was key.
