I am installing extractor fans and 100mm ducting from two separate but
adjacent toilets. I would like to run the ducting through the loft space and
to open air using a single
outlet plate on the external wall face. This means I have to join the
ducting at some point inside before the cavity. My problem is I can't seem
to find an adaptor that will allow me to feed two into one. Does anyone know
of one, or the best way to make one up?
1. You'll also need two back draft\one way valve affairs otherwise
when you switch on fan A the shitty air will be pushed into the room
that is serviced by fan B.
2. What sort of ducting are you using? If it's normall soil pipe then
a normal T. Other common methods of sourcing parts you require for
ducting include aimlessly wandering round diy stores and builders
merchants until something is spotted that can be made to do the job
with liberal amounts of duct tape applied!
3. http://www.domusventilation.com/et100.html download the pdf, look
on page 27, tees and backdraft dampers are on there. Now just wander
into a local electrical wholesaler and ask if they can get domus, also
ask for the equivalent parts in whatever brand they can manage,
probably be cheaper if its from a more usual supplier.
4. You can also order online here.
5. Remember, you can do anything with a roll of duct tape.
