Bathtub drain in the basement that is extremely slow until it gets a certain amount of water in it. At that point it speeds up and behaves normally.
Tub is freestanding and connects to floor with a flexible hose.
There is a toilet and sink in the same bathroom that behave normally.
Is this a venting problem?
