"took on new house the cooker hood extraction went though the bridging cabenet above through a flexibal pipe. this keped falling off and bulging round the space the space was filled with grease, so some sugar sope and the round ducting fixed the grease"
"The pipe is fine. I needed some to link an extractor fan to existing ducting but it took 2 lengths + connector to go through 1 cupboard. That is just exasperating. Note that the image is wrong as it shows a pipe twice as long as it really is. I should add that no-one else seems to supply longer lengths. Also, the 2 pieces must have come from different batches as the colour (white) was noticeably different but then I should have looked at them more carefully when buying.
Come on Screwfix, pressure your suppliers to supply more useful lengths."
"I bought this to install a length of duct to a shower light and inline fan IN FAVOUR of using flexi, like others I dont like flexi for everything, yes where you cant do without but surely it obstructs performance/airflow and gets mucky and seems to me a bit tissue thin. HOWEVER this was hopeless for the job, Its NOT 100mm!! its 110!!! its a silly length and you cant buy longer, yes fine for doing the wall but then what? sell a longer length also! regardless for a dedicated duct pipe it didnt seem to be snug to the fittings and none of it was cut straight!! so with straight connectors gaps everywhere!, gave up and used soil pipe which you can do longer runs with (but wont fit through the wall plate because the wall thicker..god..why does every trade have a slightly different gauge of pipe...cant we just have them all interchangeable/standard and universal?) and clips? theres no clips available or 90s."
