electric valve elimination

Pictures from removing my grey water electric valve -- 2007 Outfitter Apex 8. The valve failed closed near the end of a recent trip. This is the only device that has failed that was not obviously due to rough roads or operator error.

Kick plate is removed by sliding it sideways, and turning it slightly.


The valve and section of pipe I cut out.



Near piece was cut.


Near piece pulls out of tank connection after loosening a band clamp.


Replacement piece of 3 inch ABS with flex clamp - not tightened yet.

New pipe silicon caulked into tank connector, and band clamp not tightened yet.

Bob Ward advised that pipe glue will not work on tank connector, so do it this way.

My plan is to only use the existing manual valve and sealing cap at the outlet end of the pipe. I hope it works --

I always wanted an electric valve on the black water tank and have it wired up to the dash of the truck. Then the bumper sticker "Stop tailgating or I will flush" would take on a entire different meaning ๐Ÿ™‚

I don't see any reason to have anything in there but straight pipe.

Household bath silicon - as recommended by a marine adhesive manufacturer for ABS to the polyethylene tank output sleeve.

The band clamp shown provides the mechanical connection.

Good report. I believe that you only have the grey water tank and do not have a black water tank.

What silicone did you use.

Your main valve should work just fine, you should have a gallon or so of extra capacity.

Ditto on putting manual valve, even if you need cable to operate it.
Also silicone will not hold in this application.
What exactly failed?

Nicely done. Just curious , why not simply unbolt the electric valve and replace with a manual without cutting the pipe ?
