Has anyone installed a sight gauge on their gray water tank? I've been doing a lot of dry camping recently and the only thing that causes a problem is not knowing when the gray water tank is full................other than standing ankle deep in water in the shower!
I'm thinking a sight gauge on the side of the tank would be very useful.
Oh, and I might add, I've done a search already and found what is available on the forum. One real solution, but not sure how it worked out in the long haul.
I don't have a sight guage but we are set up to have some idea when we are getting close to needing a why to get rid of the gray water. As we increased the time we spent dry camping we needed greater gray water capacity. It seemed it was me that always ended ankle deep in the shower and not my son. I did the gray water tank vent upgrade with a little twist. Instead of connecting to the bathroom vent tube under the camper, I brought the plastic tubing I was using forward exiting up and behind the propane tank cover. I mounted an attachment on the steel tongue just behind the propane tank covers. I put a ball valve on the end of that vent tube. I keep the ball valve closed until we have water coming up through the shower. I then go open the ball valve, thus venting the gray tank, knowing in the next couple of days I will have to seek a dump station or some means of offloading the gray water.
By venting the gray tank we got 30-40% more capacity. How I came up with that figure is thus. I closed the ball valve turned the water on at a set flow rate then timed how long it took to start having water back up thru the shower drain. I then went outside, opened the ball valve (thus venting the gray tank and hearing a couple of pretty obvious "glub glub" sounds as it opened) then timed how long it took to once again have water backing up into the shower and thus totally out of capacity. I did this timed procedure 3 times to come up with my rough estimate of how much more capacity I had obtained with the vent mod.
Hope that is not too confusing
