Does anyone know where I can get a ducting 'Y' piece with a non return valve?

I have looked all over the internet and cant find one, perhaps the answer is to use both?

I need one of these:

think you have to buy the y and back draft shutter separately never seen it as an all in one

Thanks JD,

Thought that might be the case, but also thought someone must have invented one!!

Might be worth reading a post before you reply mate.

Buy both and fit the non return valves on top of the fans, not at the Y bend. Had to do a job like this not to long ago. Paid for a inspection of the local building dept at the council to double check how it was done. Passed fine.
