26RD gray tank(s)

Ok, my 26RD apparently has 2 gray tanks. 2 dump levers and 2 indicators on the panel.
My question is what drains to what and what are the capacities.

The info on the Alliance web site states 48 fresh 53 gray and 53 black, for our 22ml it's 48 fresh 106 gray 53 black. I'm sure the 106 is a total of the two tanks which I assume is the same for your 26rd having two tanks is the same.

Well, it would appear your capacity question has been answered by Socal-Paul. I believe this should also be documented on the Alliance Rv site under the specifications for a given model.
As far as what drains into each tank, that could be a mystery😀.
I would suggest you empty each gray tank, place a bucket under your discharge, open one gray lever and run a faucet to see if water comes out your discharge, repeat the steps for each faucet/drain and tank. This way you know for sure which faucet drains into which tank.
We did the same validation checks on our 310 RL to ensure we knew what was draining where and also to ensure that the tank level gauges were indicating a level rise in the same tank.

Along with what Bryan says you can also email service@alliancerv.com, give them your last six of the VIN and they will send you a general arrangement drawing. This will allow you to manage your gray water. Also if you are ever in a pinch and one of the grays is full and the other has capacity, you can open both gray tank valves and they will equalize providing you have added a discharge valve at your connection point and if you gray tanks have a common discharge point.
Hope this helps

Thanks guys. I do need to get a valve on the end. Everytime I pop the cap, a little water doubles out. Luckily it's clear and not brown. 🤣💩
