Help with conduit
Discussion
Because the PH massive normally knows the answer, from splitting the atom to which is the superior tampon.
I have to put some cables down a 20 meter run of 25mm flexible PVC conduit - what is the proper description of the rope/wire/feeder you can buy to drag the cables through?
I've tried every combination of garden wire - with no luck - is there a dedicated product out there?
Thanks all... (in hope!).

I bought a cable rod set for this very kind of job, flexible and screwed together, I think I was £20 for the set

£20 was a few years ago mind...

Pfft. So you've got the so-called answer. Buy one of these anyway...

It has to be said that PH is continually excellent when you're trying to find a solution to something - I hunted the web looking for 'draw wire' but not knowing the correct description was pointless. Nearly an hour of 'conduit help' 'conduit rope' no luck at all. Within 60 seconds for the correct answer from PH warms the cockles!
Used to used them all the time. Didnt help the weekend my (then) wife and I set out to run some phone cables under the floorboards upstairs, and I left the draw wire at work.
Quick solution, (if there is room). Borrow the MiL's Yorkshire Terrier, tie wire round dogs collar then lower the plucky little scamp into the joist void. Former Mrs C at the other end of the house calling the ankle shagger, and he obligingly ran the cables out for us in 3 seconds flat!

I'd hardly buy a draw wire to do one run of 20m.
I'd just use stiff cable. twin and earth is good. Then tape to cable you're pulling through.
So then you have to buy 2 lenghts of cable!I'd just use stiff cable. twin and earth is good. Then tape to cable you're pulling through.
and if he can;t run a length of T + E down 20m. He shouldn't be allowed out of the house unsupervised.
That and I find draw wire's s

I've got several lengths of this to do - I tried most things in there (oo-er missus) and the draw wire was only sick squid....I'd just use stiff cable. twin and earth is good. Then tape to cable you're pulling through.
Elster recommended flat twin + earth, and I'd second it.
In my personal experience of doing just exactly this (20m 25mm conduit) T+E had just the right combination of stiffness to be able to push, friction to reduce resistance to push, flexibility to go around the corners, and strength not to break when pulling.
When I did mine, I bought a standard pullthrough, and I was surprised to find it wouldn't do the job. I tried allsorts, including drain rods, heavy multistrand pvc coated copper, rope. The T+E didn't seem to be a sensible choice, so I tried it last, whereupon it did the job easily.

I can't believe I'm typing about conduit at 1am. Who started this?
I have several lengths of 20m conduit down which I need to insert cables - I've now ordered the draw wire which was inexpensive. I tried three grades of garden wire down the conduit, none of which would push through, so, hopefully a dedicated draw wire will do the trick.
I think the reason the T+E worked well is that it is flat.
Looking at the end, on one axis, it's tough to bend (on the plane of the flat), on the other axis (at right angles to the flat) it bends really easily. The point is that it doesn't tend to do what everything else I tried does do. It does not get into a spiral, that then locks it's self into the conduit.
