Stopping Drips with Secondary Dump Valve

If I’m not level when I dump my RV tanks, some leftover water can still be in the pipe. This extra water then makes its way to the sewer cap and comes out without warning on my next dump station trip. To completely solve this problem, I installed a secondary dump valve.
I purchased a Valterra Twist-On Waste Valve and installed it on the end of my dump pipe. I then added a four-inch band clamp around the mounting tabs to permanently fix it and prevent loosening when the dump hose is removed.
So far this has worked out exactly as planned. Whenever any leftover water is in the dump pipe, it now is trapped behind this secondary dump valve. I can easily attach my dump hose and pull this lever without any fear of fluid hitting the ground, or me.
Note: A secondary benefit is that it provides a small amount of extra capacity to your grey tank. If you are boondocking and accidentally fill up your grey tank, you can now pull your grey tank lever and fill up the dump pipe all the way to the secondary valve. This avoids your wife from screaming at you from the shower!
Here’s what I used for this mod:
It took me fifteen minutes to complete this modification and cost me $25. In my opinion, the skill level of this modification is easy.
