Hi all!

I'm looking to protect a bunch of cables from the elements with some ducting. I've found this twinwall ducting that looks perfect as it has a diameter of 63mm but is only available in 50 metre coils. I only need 3 meters. https://www.travisperkins.co.uk/Twinwal ... l/p/877780

Does anyone know where I can buy this by the meter? In store or online? Or something similar? I've found a couple of places online but the delivery costs are expensive!

Many thanks

dont buy from travis perkins unless you get a minimum 60% discount as a diyer and perhaps 75-80% as a trade with a normal discount

There's 5m ducting on fleabay, item number 323274232289 for £18.99 + £6 delivery. Also on there, search for the word conduit instead. If you're anywhere near West Wales, I have some 50mm you could collect.

Thanks for all of the helpful responses! Actually found that a 40mm pond hose would be adequate for my needs. Got 3 metres from the Range for £12!

Sorry to say this................. but pond hose is of little use, since it needs a lot of support*, push fit pipe would have been better, its also cheaper. £2.79 Click here

* It will sag and water will collect in it. (condensation)

Uh oh… I’ll be using it as a conduit for cables inside a chimney breast. Why would water collect inside the pond house whereas the twinwall conduit wouldn’t? Thanks.

Pond hose is flexible, and will sag, water will collect where it sags.

Since its to be run vertically in a chimney stack, why bother? Conduit / trunking is to give mechanical protection / neatness to cables, neither of which are needed in a chimney stack (Unless its a very very tall one, which yours isn't)

I wa going to use the hose as I thought it would be worth trying to protect the cables, but perhaps this could cause more harm than good. It would however make it easier to add new cables or switch cables in the future!

Thanks

Bet it wouldn't. :wink:

In theory yes it would, but in practice, you would have to have at least 2 x 90 degree bends (one where the cables come out, the other where the cables go in) bends are notorious for getting "blocked" due to the cable itself bending and taking more room (bend radius) Not to mention getting the cables to actually bend.

What you should do is when you pull your cables in, pull in an extra "any old flexible cable" and tie it to something at both ends, then when you want to add another cable that you want to use, you can attach it to the "any old flexible cable" you pulled in in the first place, and if you are really clever, as you pull this new cable in, you pull in another "any old flexible cable" for next time.
