Grey Tanks

[Chiefblueman]

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.

I wouldn't go that far. Congrats on the new 344!

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 don’t have that set-up, but would the first tank fill, then the second?

My pea brain is thinking.....,,

Waste water going to the top tank will flow into the lower tank because of gravity. Once the lower tank is full, and at some point, any additional waste water from shower/sink going to lower tank would back up due to the weight of the water in the upper tank. There is not enough pressure to push the waste water up to the upper tank.
The original question was equalizing (equal pressure) the two tanks. I think in order for that to happen, both tanks must be level.

And if you wash dishes and the lower tank is already full, then it will back up thru the drain and flow back into the shower.

How does one know which tank is higher,lower or level? We have a 2150RB and belly is enclosed like most GD.

I have a 2020 303. Have you linked the two grey tanks?

@10sne1, on the Imagine trailers the tanks are all on the same level. The trailers mentioned with different levels are 5th wheels with bathrooms in the upper level over the hitch and the kitchen in the lower level or vice versa.

I've not had an imbalance between my gray tanks on our 2400BH that was significant enough to cause an issue - especially if we're at a site with full hookups. The once or twice I noticed the 2nd tank getting full while the first was still low I just dumped some out of the 2nd tank. I don't like to drain them completely so I have enough 'rinse water' for the stinky slinky when I empty the black tank ;-)

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

You can force them to equalize, leave drain cap on and then open both gray water gate valves.

Thanks for the info. You were very helpful.

Are y’all saying there are two grey water tanks that have separate dump valves. Sorry I just woke up.
