Our aft electric
Quiet Flush head
(plumbed for fresh water) developed a problem where water
would continue to run into the bowl after a flush. Sometime it was a trickle and sometimes quite a bit more. Replacing the solenoid / anti-siphon valve fixed it. For a while. About a month later the problem came back.
This morning I called Jabsco
support and got some great help on the problem and how to fix it. If there is another discussion of this problem on this forum I wasn't able to find it so I thought I'd go through what Paul at Jabsco
told me to do and include some pictures along the way. It's actually a very easy fix and takes maybe 20 minutes if you use the quick connects to remove the part from the system.
Here's a look at the solenoid / anti-siphon valve.
First remove the screw that holds the solenoid on so you can get at the other screws.
Once the screws are removed it comes apart like this. Just to prove how easy this is, I don't know the names of any of these parts
but I was able to take it apart and clean it, solving my immediate issue.
There is a spring inside the "stem" but fear not, it shouldn't fly out but here is how it goes back.
This picture is focused on the wrong spot but you can still make out how much junk is on the diaphragm
. The diaphragm
lifts right out of the body.
This is my real issue. Paul recommended a second inline filter with a very fine screen
to try and filter the water
better. Our boat
is 15 years old and I expect to have to deal with this issue until I figure out a way to clean the water tanks
Pay particular attention to any items stuck between the diaphragm (black) and the white plastic piece in the center.
Here it is when it's almost clean. Notice there is still some stuff in the small orifices of the diaphragm. Being very careful with a sewing needle and some tweezers I was able to get that stuff out also.
Then it all goes back together just like it came apart. I hope you find this helpful.
