I've used flexible coiled drain rod (minus the business-end). Works a treat.

I have just had to pull a load of cables through my duct. There was no way a fish tape / or rod would be pushed through as the final bend is tight and packed with cables. I disconnected the main battery cable to the engine, used the crimped eye to attach a draw wire/rope and pulled it through from the other end. Pulling is far more effective than pushing.

Umm; you usually run fish tape all the way through, then use it to pull the cables back through. They're made fairly stiff so you can push it through some resistance, but are somewhat pliable to get around corners. Probably won't go around a tight 90, though, at least not without a lot of fiddling.

If you have a fairly clear duct, another method is to tie a small pice of cloth to the end of a string or rope (to generate more air friction), and use a shop vacuum to suck it through the duct, then use the string as a pull line.

A few of you on here may remember Mark Halliday who was a regular on here before he ripped the rotten deck out of his 6.5M Porters to replace it, then never got around to putting a new one back in.

Anyway, I was round at his place one day and we were looking at the extension he was half way through building on the side of his house. I noticed that he’d installed a 1&1/2inch conduit under the floor from the old kitchen to the new room, a run of about 12 feet, and I tentatively asked how he was going to pull the cables through it without a ‘mouse line’ to help.

What he did next made me laugh, but will stick with me as a ‘top tip’.

He grabbed a ball of string and the handkerchief out of his pocket, tied the end of the string to the corner of his hanky and stuffed it in the end of the conduit. We then went to the other end of the conduit where he used a vacuum cleaner to suck the hanky through in what seamed like @1/2 a second. He then of course had his mouse line through the conduit.

It probably wouldn’t work where there were lots of cables already through the conduit, but it was very impressive.

On a related issue ... I now have the pump (it was a bit late turning up!) and the fish tape so at some stage when weather and free time coincide, I'll be putting it in.

I figured that rather than drilling holes in the deck and potentially creating a water ingress point in the future, I might just stick the pump base onto the deck with something like Sikaflex (you can't buy that here but there is an adhesive sealant called Stixall which seems pretty good).

I've never really tested the tensile strength of Sikaflex type adhesive sealants on a small plastic fitting onto GRP - what do people think - will it be strong enough for this? I think it would probably be better than an Araldite type epoxy adhesive as they are usually quite brittle but any thoughts welcome...

I'm sure you want to keep the pump as close to the deck as possible but your chances of success are obviously much greater if you increase the contact area. Can you find some 3mm plate and bolt the pump through with small countersink bolts and nuts? Then stick that down with ya sticky gear.

Sikaflex type adhesives need a bit of surface area to work really well. I don't know what design base is on the pump, but I'm sure it's worth trying.

The technical term for the way Sikaflex 'Grabs' what's being stuck is:- L.S.T.A.B.





Or:-

Cracking idea
