I live in my RV, do I still need to open/close my black and gray water tank valves?
Since you still have a tank for your black water you do want to keep it closed until you're ready to dump. As the first segment of this help article suggests, if you keep your black tank valve open all of the time then all of the water will run out and you'll be left with solids. Your gray tank isn't as crucial since it shouldn't have any extras with it, but I would still wait until you dump your black tank that way you can dump your gray tank afterwards to help clean out your system.
Thank you, most of the things that you went over has proven that all it takes is a little common sense and a couple of minutes to research. Thanks again for the refresher!
I'm glad we could help!
Boondock camping. I purchased a black holding tank and a fresh water tank from an old travel trailer and put them in the bed of my truck. Each is about 40 gallons. They were only 10 dollars each. I also bought a grinder pump. I pump my gray water into the holding tank in the back of the truck. Than I refill the fresh water tank from the fresh water tank in the truck bed. Than when we go to town I empty and refill the fresh water tank in the truck bed. This extends our stay without having to pull the trailer back to town to empty tanks.
Thanks for sharing your experience! This might help our neighbors looking to stay on site a bit longer.
