hi mark
yes it is from experience. gate valve in the basement is doable but adjusting sucks. detritus will always accumulate causing a change in flow in the valve and the higher the head, the more sensitive it is to adjustments.

If the filters in the basement are totally closed of to the air "closed system" the need for any valve would be gone. The only control you would need is a valve on the return pump. This is a question not a statement .

your thinking a sealed vessel in the basement, something like a giant canister filter?
