Basement unvented cylinder

[kozak1968]

Just a quick one, had a request to fit an unvented cylinder in a basement, its got no drain. Do they do a pump for the discharge? I dont think so. Does anyone know.... Thanks guys.

From the tundish into a tank and a submersible pump to pump it up an out to drain.

Only the manufacturer can say yay or nay. Without written consent from them I would not be fitting.
Heard of some D2 pipes terminating to a sump but never seen any.
