55 Gallon Barrels $10-20 in the GVRD

Not knowing how you would 'inline' this with your sump...
The whole lid itself is locked down with the steel 'ring' and stands up to transport, so it's tight.
The lid itself has 2 'bungs'. One is 2" FPT and the other is "3/4 FPT.
The larger one is the industrial style that requires a 'wrench' or 2 long-handled screwdrivers locked together in a cross to open and close it.
The smaller one requires a slip-wrench to open and close.
The lid can be drilled and pumbed with bulkheads. I'd suggest these Uniseals as they are great for irregular surfaces and PVC just gets forced into them

Hope that answers your question, but I'm here for awhile if you have more

And the lid has a seal to the drum

I'm rushing and not completing my thoughts...
I bought the Uniseals from Bulk Reef to put into this style of drum.
I plan on having one down low for draining into a bucket or running a hose, and the other up hi in case I over-fill it with RO/DI.
That upper will go to a drain.

Yup, I picked up one in Aldergrove last night, food grade and great for ato systems as well.
