Thx for the info guys

[Safe? Kitchen extractor thru wall into garage]

I am about to buy a bungalow & have found a few things of concern.

The biggest concern is the following:

The kitchen extractor has been ducted through the kitchen/garage wall into the garage space across the wall & out through the soffit.

This has been achieved by using a WC U bend upwards out of the kitchen wall, then connected to a Soil pipe U bend to turn it left, then connected to a length of soil pipe, another U Bend soil pipe upwards over eaves then using a plastic flexi hose out through the soffit.

Does this comply with the fire regs?

Is it safe?

I realise there is an issue with the distance & bends causing back pressure to the extractor & possibly overheating, but is the whole thing safe or allowed given that it now breaks the supposed fire break between garage & house?

There is connecting garage door into the house utility room that has no closer (never been one fitted) & no Intumescent fire strips fitted, although the frame is rebated for them, so if they cant comply with the simple building regs, I have to wonder about this method of extraction thru the garage.

I know, a little bit of knowledge is dangerous, but I am concerned

Thx
