External Ducting

[RJH]

I've got a minor domestic dispute going on with a neighbour, who recently fitted a kitchen extractor fan that vents directly into my garden. When I raised it with them at the time, he said there was no other way, and we agreed that he'd let me know whenever he used it - which I figured would make it pretty impractical for him to use, so I left it. He also added that they don't cook fried food so saw no really use for it - it was a fixture that came with a new kitchen.

Of course, it's been in regular use without notification, and they don't answer the door when I go round to discuss. So I'd like to duct it on to their garden. It'd need one of these (90 degree fan to duct piece):

and one of these (90 degree rectangular duct to duct piece):

connected with about 2m of rectangular 100mm duct. It doesn't seem to be in black so I'd paint it, and fix with channel clips.

Would that be the way to do it? While I'd guess its intended use was interior, I can't see any problem using it outside, unless I'm missing something.

Just tape up the extractor outlet with duct tape. Sorted.

Dose of expanding foam might get some attention:-)

Might be as well to drop a note explaining what you are doing.

Whilst much depends upon the actual fan your neighbour has used, their ability to cope with additional ducting varies considerably.

The end result may range from being imperceptible, to being equivalent to the handful of used socks I guess you would like to shove into it.

Additionally, he may well _claim_ reduced performance, simply to be difficult.

Does the prevailing wind aid or oppose your redirection?

you are allowed a certain amount of openings in a boundary fire wall ........

[RJH]

Yes - but I'm not too worried about that side of things. Not yet anyway. I can't see any duct guidance for any of the Manrose fans. I'd assume it would put a little extra stress on the fan and reduce efficiency, but hey.

That's part of the problem - it vents into a sheltered area, with walls on 3 sides. So unless there's a fair breeze if just sort of hangs about in a hollow. The prevailing wind would potentially push the newly sited duct waste over another neighbour's garden - but it'd take some untypical weather for that to happen in a noticeable way.

I do propose to give them a note outlining the plan. All they would see is the rectangular elbow outlet. And all they would smell is their own cooking. Can't really see why they'd object. The eyesore is on my side.

This is presumably to stop smells? it would need a lot of ducting to stop those with the wind in the wrong direction.

Is there a visible spigot of a pipe you can hang this on?

2m sounds quite a lot of pipework.

Without seeing a photo or plan of the installation it's difficult to comment on the practicality.

I'm sure the neighbour will consent where offering to do the work gives the impression of how important this is for you where the alternative can only be uglier.

Foam gun ?

Even if you are trespassing on your neighbours property ?. One for a solicitor.

No-one with a brain would do that without talking to the neighboor first.

[Jim GM4DHJ ...]

these people all did it ......

How would you fix it though? You could not fix it to their wall. The other thing is that depending on the airflow outside, you will still be able to smell it. I'm not sure what the answer is, and obviously your neighbours are using the ostrich head in the sand approach.

What it really needs is some kind of round table discussion between you them and an expert or maybe the bloke who fitted it in the first place without asking the neighbours.

Fixed using clips designed for the job - they wrap round the conduit and screw to the wall.

Maybe, but that's fair enough in high density urban living. What I don't like is the exhaust directly into my garden.

Yes, I've asked them to do that. But it was nonsense in the first place - they could easily have run conduit internally, or mounted the fan on one of the other 2 external walls (it's an offshoot kitchen).

[RJH]

I've fitted on of these before - it's a Manrose, and being the brown louvred grille there's a 100mm round outlet. The 90 degree piece fits to that.

It's sold in 1m lengths. If I decided to link my cooker hood fan to the outside it'd take 2m, so I don't think it's that unusual. Could be wrong of course - hence asking :-)

It's the brown square thing, centre left.

Yes, I'm sure they will. I'm just annoyed it's come to this. As for ugly, I don't think I'll have too much of a problem persuading the jasmine to conceal it ;-)

Plant some creeping ivy up against their house wall.

you are lucky they dont complain about your intrusive plants.
