Can you help a damsal in distress? I've recently had a new kitchen fitted which included a cooker extractor which has an external vent.

Yes there is, and they are available in any diy store, it fits in place on the outlet, on the outside wall. you probably won't even have to redrill. It basically just has a few fins on it that close under gravity, when the fan is on, it pushes the fins open. Supprised it made the kitchen considerably colder though. If you have a radiator in the kitchen, have you felt it to check it's working fully. If it's cold at the top it needs venting, if its cold at the bottom in the middle, your system may need flushing. Hope the flappy vent works.

HI , As well as an outside vent which only opens when switched on . there should be a non returnable flap on the inside of the extractor . at the other end of your flexi ducting extractor end. hopes this helps as you should not be getting blow back when windy outside

Hi, sorry to hear your kitchen fitters coulld not sort this out for you. There is an external vent that is fitted with gravity operated shutters. when the extractor is operating the shutters open with the flow of air and when the extractor is off the shutters drop shut. Hope this is of some help and reduces the draught in your kitchen. kevin.

normaly a hood vent only opens when the hood is on i.e there our flaps that close down when it in not on. if urs is not this i have no idea what u have had fitted

if your outside vent has a cowl fitted replace it with a vent that only opens when the extractor is working ,they are fairly cheap and easty to replace
