    Grey Tanks

    I have never had 2 gray tanks, our first weekend out one tank is 3/4 full #2 is a 1/4. My question is will the tanks equalize when when one gets full? Thanks

    One should be the kitchen sink, the other one should be the bathroom sink and shower. They do not equalize. Just depends on how many showers you take compared to how many dishes you wash.

    No, the two tanks do not equalize (on their own). There are people on this forum that have installed some sort of valve that allows this, however. Hopefully one of them will show up here and explain.

    place one of these on your discharge pipe https://www.amazon.com/Valterra-T58-.../dp/B000BGHYJS
    Close the Valterra and then open both gray tank valves. The 2 tanks should then equalize.

    You can get a valve like this to equalize the tanks. https://www.amazon.com/Valterra-T58-.../dp/B000BGHYJS Leave it closed and open the two gray tanks, stuff flows between them. It's also good as a safety valve in case in of your gate valves leaks, or someone accidentally bumps or pulls one.

    I just took our 344GK out for the first time and put the Valterra vave on there. When I went to open the two gray tanks to level them out - it did not work. I'm not sure why it did not work as it worked with my Reflection 315RLTS but no such luck on my Solitude 344GK. I have a list of items needing warranty work and will add this one to the list. Seems odd that it didn't equalize the two tanks.

    Is it possible the gray tanks are on different levels?

    You may be getting nervous about something that will not matter in the long run. I did the valterra valve trick with mine and they have never equalized on the panel lights. As a matter of fact those panel lights have been all over the map, so the only thing I use them for is an indicator of what MIGHT be in the tanks. I did an experiment after both greys read as full and found that we were able to take four more quickie showers and four dish washes before the water backed up in the shower pan. Another advantage is that the drain lines will give you some added capacity.

    I did do that with the greys, but I don't think I will do it with the black !!!!

    On my 375, the kitchen sink grey tank is mounted above the shower/bathroom sink grey tank. These tanks cannot be equalized as gravity will completely fill the lower tank.

    I didn't even think of that. You are correct. The kitchen sink is on the first level and the bathroom is on the second level. Geez, I feel...stupid..lol.
