Grey Tank Equalization concern
Having 2ea Grey Tanks, I learned from this forum(not the owners manual) . One is for bathroom shower & sink, the second for the Kitchen sink, no cross flow between the tanks. Learning from the forum I installed a gate valve @ the end of the sewer drain. Then I should be able open to both Gray tank drain gate valves & the levels should equalized.
I tried this today & the results are not as expected, one tank was 2/3's the second was 1/3. Now, one tank indicates full & the other is empty. I don't think this is a good thing, or will the water start to fill the empty tank.
Has anyone seen this & what have you done?
Initially I wondered about the elevation of the tanks & would they be the same. My guess would be low in the frame, maybe not, maybe the bathroom is higher.
Thinking out loud if the trap for the kitchen sink is above the tank it should equalize.....me thinks2022 Solitude 310GK, Factory option Include, Dual Pane Winders, Slide Toppers, Solar pacakge, Gen Prep, Pull Out Kitchen & Heat Pump

Yeah, thanks for this post. Got to say I've been disappointed with the equalization potential. Like you I got a gate valve and was hoping that the two tanks would end up with equal levels. Since the shower side fills up much faster on ours, we wouldn't mind shifting a bit to the kitchen side. But no joy, with both grey valves open there was no difference in tank levels.

I think a lot depends on the physical tank layout. For example, in my 399, the kitchen tank was physically on top of my main bath gray tank. In cases like that, it's hard to get a true 50/50 equalization.

@FT4NOW
It sounds like this model with the drop frame that the bathroom grey tank is lower than the kitchen grey. Explaining why they do not equalize.
My last single brain cell thinks if the drain gate valves are left open the grey water will migrate from the bathroom tank to the kitchen tank. The level would slowly increase while showing full in the bathroom tank.
I'm waiting for someone to say, yeah I do that all the time Ha!2022 Solitude 310GK, Factory option Include, Dual Pane Winders, Slide Toppers, Solar pacakge, Gen Prep, Pull Out Kitchen & Heat Pump

OK, I dare you to test this out! (OK, so not really, I triple dog dare you ) Keep adding to the kitchen tank while watching the shower floor. If your theory is correct, the kitchen tank will fill up. If not you'll start to see some water in the shower (the lowest point on the bathroom side).

I wanted to do the same thing, I cant say for sure in a 310 but in my 375 the bathroom gray tank is in the drop frame and the kitchen tank is in the main frame (higher). The equalization idea doesn't really work well in that case. They need to be at the same level in the frame.
