1 FAQ on the Mushroom roof vent, plastic

re the GY20 roof vent, as i'm trying to find a 'horizontal roof mounted and waterproof outlet to install on my Bessacarr E695 roof (bathroom location). could you inform if this is (a) Flange mounted & (b) does its 'outlet' vent via the top of the unit, or from 'under the dome', as it appears to have 'outlet grooves' on top from the site photos ? All that I really need is a none powered flange mounted & weatherproof dome outlet able to connect up to a 100mm pipe..
The mushroom vent, our ref. 123804 is a non powered vent which may be suitable.

Had to replace the vent on my Adria adora as it had deteriorated after years in the sun.

Caravan Roof Vents

by Mr S Elliot (18 Jan 2023)
5 star review(5/5)
Replacement vents identical to originals so no problem fitting them. Reason for replacement due to destruction caused by UV and omething others caravanners should be aware of. Shame caravan manufacturers don't use UV resistant plastics everywhere.

Just The Job

by Robert (22 Aug 2021)
5 star review(5/5)
The vent measurements given were accurate and fitted just fine. It did not take long to replace old one which had become brittle. Other reviews on the website were positive. I was hesitant only because website showed only one pic and it was not clear that the inside fixing plate was part of it. It was and was all good and not expensive.

The mushroom roof vent arrived quickly and was fitted in minutes. I cut the sealant on the old vent with a cheese wire, cleaned the old sealant with diesel, fitted the new vent with non setting sealant into the existing hole (110mm). Job done in less than an hour.
