How to Know When Blank Tank is Full When Using Flush King Reverse Flush Valve

Published 10/07/2021

Question:

How do you know when youve added enough water to fill/flush the black tank WITHOUT overflowing your toilet. Wondering if it would even work for my Winnebago View as the connection would be extremely close to the ground making it hard to drain properly if it even fit in the space.

Thank you for the photo, and there should be sensors with a monitor for your tank that tells you how full it is in order to use the Flush Valve for RV Holding Tanks and Sewer Hoses # F02-4350.

If you don't have that, you can still use the Flush Valve # F02-4350 but you'll want to be sure to limit the water flow going in so you don't have a real mess. But really, this is best used with black water tanks that have monitors which tell you how full it is.

This will work for you unless your connection is literally a couple inches from the ground, as it is angled at the connection point. I have added a link below to a video review for you to check out as well of the Flush Valve for RV Holding Tanks and Sewer Hoses # F02-4350.
