Hello everyone,

I am currently in the process of building a darkroom in my basement and have what I believe to be a simple plumbing question.

I'm trying to find a supplier for a sump box - my plan is to have the sink drain into a sump box which will pump the waste water above the drain line (I will have a one-way check valve installed), then it will pitch down towards the main drain for the house, which I'll tap into. Trouble is, I can't seem to find a supplier for this item - sump pump in a pvc box.

Any advice here?

Many thanks.
