So we did blog posts on RV Tank Use and hoses that included a CAM Lock Hose System and then we did one on Electronic Dump Valves. We mentioned that we put in the electronic dump valves so we did not need to go outside each time to dump our gray tank as we leave ours closed. So that blog post and video opened up quite the conversions here and elsewhere dealing with keeping the gray tank open or closed when you are parked. NOTE: WE DO NOT PROVIDE THE BELOW SERVICE….WE HAD IT DONE!
We treat the gray tank like the black as it does have solids that get into it from washing dishes. You also have grease from cooking, not that you dump that down the drain, but it does get in again from cleaning. Don’t forget the washing detergent, shampoo, soap, etc and so on. Remember it is not just water going down the drain, these items can and do collect on the bottom of the tank and on the sides.
