Unused grey water tank

[CalvinD49]

This puzzles me. We have a 2018 34RSBS. When you fill the water tanks there is one place to fill them both. However, there are two grey water tanks, one for the kitchen/bath and one for the washer, which BTW we are not going to use, and each has their own discharge valve. Why aren’t these two grey water tanks connected internally so you can use them both instead of having one never used?

Probably more a cost issue to do so than to just use two separate ones.

The solution is to purchase one of these and while leaving the black valve closed, open both grays which will allow both to act as one. I have 3 grays and can make them all act as one large tank using this.

Just make sure that before you open your black valve, close both grays so you don't allow the two to "mix" as well as still having gray water to flush things out after dumping your black.
