Clogged Drain
My gray water tank won't drain. While washing dishes this morning the sink started filling up. I thought at first that I had left the dump valve closed but when I went to open it it was already open...

The problem is you leave the valves open! The system is not designed to do that, you get build up and it clogs the pipe. To try and fix it you need to open the hot water faucets and hope it is enough to dissolve the build up! Both tanks, black and grey are called "holding" tanks. They are called that for a reason, they hold the contents, and then are drained. This action "sweeps" out any build up and keeps them clean! If you are able to get the tank clean, please do yourself a favor, and keep the valves closed, until the tank is full, then drain! Simple concept, why do so many people think they know more than the engineers who designed and built these systems?
When hooked to sewer I have left my grey tank open, been doing so for many years and full timing for nearly 6. I do once a week turn on tank spray, close valve and fill tank while doing black tank then open.
Never been a fan of being in the shower with the pan filling from the tank being full.
Agreed with leaving gray tanks open while on full hookup. Likewise, always leave black tank CLOSED until full or leaving, for the very reasons you mention. Can't think of how there could be any buildup in the gray tanks.
