20 foot pvc?

[GerryB]

I have not seen it or used it but my gc says they have it, grey, schedule 40, sunlight resistant. Anyone use it? pros and cons?

I believe it is special order so it is available. Disadvantage is length and advantage is length- I can see it for long runs with less couplings.

It is available as is 20' EMT

It seems ideal for site work.

it was popular 20 years ago. it was schedule 20, pvc. the 20' lengths are light, but fragile. it was used mostly for the utility companys primary service. haven,t seen any lately.

It is possible to bend extra large sweeps with 20' lengths.

I literally installed miles of 5" x 20' pieces of Schedule 40 under Michagan State University 4 years ago. 20' pieces are the only way to go from a production point of view :thumbsup:. It cuts the cost of glue and the labor to install it in half.

Yup, 2 ways:
1 : large enough heater and some time
2 : large enough stakes and some space

If heating it helps to have caps for the ends to hold the heat in. The older, more knowledgable sparkies in my area tell me it heats faster that way. I tend to believe them.

We use it all the time for long runs, it's just like the regular sticks of pvc, only 10' longer.:lol:

Supply house keeps a lift of 2" on hand usually, and can usually have more within a day or two.

We are still using a lot of the thin walled 20 foot lengths here. They are not UL listed raceway. There may be listed sch 40 or 80 available. When we use the non listed thinwalled pipe we are using primarily for rodent protection of what is otherwise direct burial rated conductors. If not for the threat of rodent damage many of these installs would probably be direct burial conductors only. We are using it mostly for long runs on farms. Like 1400 feet from road to irrigation wells.

That could have saved some time on some solar groundmounts I've worked on.

This is 3" that the gc is buying, and it's only an 80' run, kind of senseless. Does it cost more? And can you install it yourself? Let's see, set it up on a block, swab, and start running. And it's not glue, it's CEMENT, as we all know from a different thread.

The "older, more knowledgable sparkies" at the shop I work at built a massive jig, capped the ends, poured in the heat, and bent a lot of really big, really nice sweeps.:thumbsup:
