No fixed future plan. What do I pre-wire? HDMI/4K woes.

On a property with six vacation cottages, the owners are systematically demoing them one by one and rebuilding. I did the pre-wire on the first one a couple of years ago. They are small two bedroom things. For the first one they knew what they wanted: a main room Tv , rough ins for TV in the bedrooms, network, and three zones of audio. No problem. I home ran speaker wire, HDMI, cat6, coax etc etc. It was one floor with a unfinished basement so lots of access to fish any future needs.

So the sister is starting the rebuild of her cottage. It's larger than the other since it has a second floor. I'm guessing 1200sqft. At this point she doesn't know what she wants to happen so I'm looking at a pre-wire to cover most basic needs. My question is about HDMI. In the past I've run an HDMI, passive and then later Redmere, and a couple of Cat6 and felt we had it covered. But now with 4K being a bit of a cluster, I'm not running Redmere and am unsure about running passive HDMI. Of I'm home running again, the most future proof cables are quite expensive and at this point she doesn't know which rooms will end up with TVs. The shot gun blast of running HDMI all over the place will get really expensive. I'm leaning towards the passive HDMI, two cat6 and then conduit. I feel like that will pretty much cover future needs but I'm looking for advice on what others are running.

Thanks

Craig.

For TV's, run conduit. Your butt is covered that way. It's what we're suggesting to all our clients.

Thanks and I agree.

I've never done conduit in a whole house system though. Just single rooms. I'm pretty sure code doesn't allow for more than 180deg of turns before you provide access and while that doesn't aply to low voltage where I am, any more and friction will prevent a good pull. What are you using for longer runs that may require multiple turns? Hidden access? Access via future drywall repair? I've never tried the Carlon Flexible conduit and I think this could be a good candidate. How's that for friction on the inside?

Does the NEC actually address the total angle of turns WRT low voltage?

Big conduit from the head end to the attic or crawl, smaller conduits down to TV locations.

In BC we're allowed no more than 360 degrees over a run before a pull box is needed.

I have a 16,500 sq ft house with 30 TV locations. Not a single run needed a pull box.

Craig it's 360 Degrees in the Canadian Electrical Code. Most large projects spec pull boxes for communications and AV to have straight pulls through the boxes.
Basically don't use the box to change direction on a pull.

I am trying to future proof my own home and will be doing 2" conduit and using 12" x 12" boxes that I will hide in walls with access in cabinets etc. You need to get creative.

I'm not sure it does for low voltage but I feel like it's best practice anyway to limit them. I can't imagine an HDMI has a lot of strength when it's pulled too hard.

I am calling Brent for sure, but not on a Sunday night.

I love the idea of the 2" to the attic. I will put that in my pocket for later, but this place is all vaulted ceilings and spray foam. The unfinished basement is available though and those large access boxes with covers are a stellar idea.

Thanks for the ideas!

My experience with pvc conduit is that 270 degrees should be the max.

That's why I run flex(smurf tube).
You can make sweeping bends and,done properly,it's almost like a straight pull.

I like 1.5" flex conduit to each TV location, from the attic or basement.

Install other cables outside the conduit, the conduit is for future cables, it should be empty.

So is it safe to say, to get any 4k@60fps 4:4:4 - fiber will be the only way to go?
