I am currently in the process of having a kitchen fitted by a couple of
very good Polish builders who speak very little English.I recently
purchased a
conventional Extractor and the builders have said it would be far
better
to remove the air outside plus there is already a large vent hole where
it will
be positioned. I rang the company where i bought the extractor /
Kitchen
and they said I would need 2metres of ducting tube/2 Jubilee clips/a
through wall tube + a non return valve. When i described this 2 my
builders they looked at said no you just need a pipe from the extractor
to the outside?

any takers on what both parties are on about ?

I no nothing about this -help

Your builder probable needs one bit of 110 mm (4'') diameter pipe for
through the wall. If the extractor has an outlet point directly on the
rear, then the pipe fits through the wall, and extractor sits over it.
Viola, done.

You'll need a grille on the outside with a fly (insect) screen on it, but
that's not to do anything else but keep the flying / crawling bugs out your
house. If the extractor maker says you need a one way flap in the system,
then all you need is a grille that has gravity dropping flaps on it to stop
the wind blowing back up the pipe.

Go with your builder on this, as the extractor company only want more money
from you.
