How do ypu acess guest heqd pump

[WhiteRockMike]

If it's a Jabsco electric flush toilet using salt water, then there is a pump behind the smoked glass sliding doors in the hallway that provides water to both heads. It is a demand pump with a pressure shut off. Then each head has a solenoid valve that allows the water into each head when selected, and the drop in pressure activates the pump

Wish it was. Its a vacuflush with generator behind wall. Almost inacessable.

Kent, there have been threads in the not too distant past the have covered this. Got to run out now, but will try to search on return. Basically thru the little door next to stairs (removing door frame gives a little more room) or dismantle the guest sink cupboard, but you have to be skinny. Cheers

The best access to work on the pump is through the cabinet under the sink (yes you read that right...). Take out the back, floor and sides (about 20 screws) and you can crawl in and actually sit in there and work on it. I have done this twice. It's far easier than trying to work on it with one hand by feel through that little door under stairs. A more permanent solution is to 1) cut in an access opening through the fiberglass directly behind toilet and install one of those hatch doors, OR 2) raise the platform upon which the vacuflush pump rests about 8" or so, THEN modify the stairway to the pilot house so that the bottom two treads and risers are removable. That will give good access to work on the pump with both hands and eyes. I chose the second option. Good luck!

Kent, here's the thread. I notice that you were also included in a past thread as well, so you probably already have/know of this. If you remove the small door and door frame, you can get the pump out then work with it on a bench to change out duck bills etc. Its tight but if it's the pump you need out, leaving the tank in place, the pump will come out thru the opening.
