Re: [Connectivity] Help: We accidentally cut our comcast HCI lin

NO NO NO! 4" is NOT OK. Cable should be buried at least 18-24" below, in a trench with crushed stone and PVC conduit, and any appropriate barriers/drainage material put in. Direct burial is just doing a crappy job. Ours are probably 24-36" down in ~2" PVC conduit that is laid in crushed stone. It runs along with telco and power lines, each in separate conduits. Even our pool wiring is probably 18" underground, in trenched-in conduit.

Is this for a house connection?

Yes, for a house connection. Done properly.

There is no reason that irrigation should be in before the conduit is laid. The conduit should go in early with conduits for power, cable, and phone service, and then the wires pulled through later. I'm sure there's a lot of shoddy work out there, but that's how it's done right.

Well then that would require the customers paying to have it put that deep. Up here in Canada there is limited time to bury cable and 9.9 times out of 10 drops are just spaded in anywhere from 4-8 inches depending on the shovel and ground levels. I agree everything should be in conduit but then expenses will go up and so will your bills. I have been doing this for many years and the time I was in West Palm beach working for adelphia as an installation tech we had to bury all new drops, we had 25 techs, I can't see 25 trenchers, rolls of conduit going out with every truck to bury a line 25-50 ft from the tap, imagine the costs involved.....its not happening buddy!

In southern florida there where no drops to new houses, they were only installed when the customer ordered service and many times those irrigations systems are already in place.....

That's really poor planning on the developer's part. The conduit should go in with the electrical and phone service, separated in the trench.

The conduit doesn't cost that much if you throw a few extra conduits down there when roughing in electric service.

I can't blame the cable company for doing a shitty job if the customer didn't prepare conduit for them. It's the home builder or owner's responsibility to have an empty conduit ready for cable installation if they want to do cable. If we ever got FTTH, for example, we either have an extra conduit, or if not, we would re-pull it with a new phone line and fiber by using the old phone line. Irony is the street has a conduit for fiber, but AT&T doesn't do FTTH, so it's just sitting there empty.

When the builder build the house, he trenched in conduit for power, phone and cable, and buried it with pull lines in it. CL&P, AT&T, and Comcast each pulled their cable through those conduits, and made the appropriate connections to the electrician's wiring inside the house.

It's not exactly rocket science to do conduit installation. You have to CBYD, you probably need a backhoe unless it's a short run, some crushed stone, and some conduit.

IIRC, in New England, the trenching actually has to be done below the frost depth, which is about 48" here. Too much less, and it will frost heave. They might be able to get away with a bit less, but it's not 6 or 12" down.

Thats how its done all over the United sates for the last ten years or so. But not all house were built in the last ten to twenty years. I guarantee i could come up to new england and find houses without conduit. The way its usually done is the builder gets in touch with the local phone and cable company and has the conduit supplied by them. The cable company wasnt always willing to supply conduit to someone that may or may not get service from them. The phone company often just supplied the phone line for direct burial.

You can find houses built last week here with no conduit for anything. People won't pay for it. Direct bury it goes.

I'm not saying there isn't any shoddy and low-quality work done. Yes, there is. I'm saying that quality work is done with conduit in crushed stone, several feet down. Enforcement of quality may have gotten better over the years.
