I currently have a Vortice extractor unit fitted to the ceiling above my shower. I want to buy an in-line extractor. Does this spigot fit over the hole where my current extractor is and is it a simple task of connecting this spigot to the in-line extractor via flexible ducting. Thank you
I have a 130mm round flexible aluminium duct coming from a boiler and terminating to an exterior wall. Is this product suitable for that or can you recommend one that is ?
