Plumbing system

[eZAK]

I curious about the plumbing system in my HC.
There are two dump valves in the 'convenience' center (Black/Gray) and one valve in its own door, (?) I'm assuming another gray tank, But how is it plumbed?

Thanks for any info you can provide!

Based on your floor plan I would say that the pull in the convienence center is for the bathroom tank and the other one is for the kitchen tank.
