use water flow to flush fishtape down the conduit. use fishtape to pull fibre optic cable though. install sealing plate and terminate fibre cable.

@@sonacphotos Aha, Now I understand. Thanks! Cheers!

Blue collar engineers are not engineers in my eyes.

@@sonacphotos Why water? Seems a bit wasteful. Wouldnt a vacuum be better?

@@scwfan08 Ever tried sucking on a really long tube? You'd need a VERY powerful vacuum for that, it just wouldn't be effective. Water isn't exactly a scarce recourse in this part of the world.

sometimes they just run way more than what they need. then later in the job they will cheap out on the stupidest things.

Find the old GTE commercial where they show a tiny fiber optic cable poking out of one of the huge openings where the old cables were....quite a size difference back then

The cost of doing 10 tubes is mostly the same as doing one. Usually, what costs more is the land through where the tubes go than the tubes themselves. As so, they pass as much tubes as they can so that it becomes future proof.

@@ClaymorePT Similarly, within a building anyway, the cost of running 2 strands for a single device somewhere is about the same as running a 12 strand. Termination costs aside, the benefits of having spares available when future needs arise far outweigh the small cost increase in the short term. I imagine this really makes sense when you're dealing with digging up roads, tunneling under railways, etc. as these are very labor intensive (read expensive) operations.

Manhole seals out debris liquid

Ground wayer always finds its way into UG ducts.

I meant to say "Ground water always finds its way into UG ducts".

​@@boldford So that seal is meant to keep water from getting into the conduit then?

@@jimsvideos7201 The seal is to keep it out of the jointing chamber.

watching this made me have to go pea 🥺
