Question about tips for laying PVC pipe to speed me up

[Fulthrotl]

I wanted to ask a few different questions to some of u experienced people.

the best way to run pipe in a ditch is to stay out of the ditch, if possible.

and realize that no matter how much you plan, sometimes you have
to get into the ditch. mule tape, and schedule 40 pipe caps slipped on
the end of pipes are the difference between profit and loss on a job.

dont bother with the brush. pour it out....

here the poco does not have to bother with AHJ inspectors or NEC, and they just pour some on top of the 4" male side, no primer.

my aid for pulling 2" and larger together conduit sections is a chain wrench, nice solid grip, twist and pull

south west doesnt worry about frost expansion stuff... only time we use it is roof runs over 100'. but I get the pun, haha... I think the justification is some of these manufactures buy inspectors boats and Alaskan hunting trips... aside from that's what the manufacture requires...

louisanaapp, the word is vulcanizing. how did I know so many would object... it proves that when someone says "in my 20 years ive never..." well, anyway, draw your own conclusion. I started in san Francisco which had unique rules and ended up here with the same thing...don't know why.

I can tell you the manufacture requires the primer- and it ends up welding the joint...try it and compare. so take your broken joint in the 3' trench. sooner or later you will end up on a job with a 12' concrete foundation with 3 cranes, 5 pump trucks and about 950 concrete trucks in 30 hours or so. hard core? a bit. but not as hard core as the hoppers the cranes are dumping concrete on your pipes from about 40', let alone the pump trucks..(the concrete guys NEED the concrete to fill the voids, aint no gentle about it) and steel guys walking on your pvc in the middle of the frame is another story! in big slabs improperly supported pvc floating to the top is a issue- ive seen joints break just from this...that were not primered!

do what thou wilt... its a little odd because I know you guys have pulled joints apart and the cement alone didn't do a darn thing..."well crap, look at that! All the glue just made a ring around the bell!" :/

a waste of time.... goodness. anyhow, 1" and smaller it is not required...but I do it. but we have inspectors that count the stupid threads on RT fittings!

Yeah I understand your concern I wasn't trying to be arrogant. 99% of our runs don't require concrete on top of conduit. I have been on a job where we did that and we had to build rebar around the pipes and there was a compaction test, ect but I do take extra precautions then. Just because people don't do it doesn't mean it isn't right when I did flooring for a couple years you're supposed to use a stretcher to stretch carpet not a knee kicker but most installers dont...this is like one of those cases where one way is better but the end result is usually the same one just goes against manufactures specs and makes u liable.
In a field where the bottom line is more important than quality you aren't gonna find many companies that would add 1/3 extra time to labor just so the PVC is unbreakable they would rather be extra careful with it and take a chance. Just because I am an apprentice doesn't mean I'm automatically naive as I said my coworker is a 30yr + electrician that has his own misconceptions he won't even tighten mc fittings because he said it shorts stuff out..experience doesn't necessarily mean anyone is correct.

I'll have to find a manual online for our bobcat it's an older one probably from the early 90s I think one of the first with the x-change system.

perhaps... I though at best he was dealing with a mini track hoe. either that switch in the little compartment is on or off with the skid steer running.either way, any size equipment, key on engine off and jiggle appropriate control should clear it...sometimes.

Laapp, I didn't think you were being anything- just trying to help. I sometimes don't understand opposition from others sometimes...oh well. try it yourself sometime. on joint primed and one joint not. pull the one apart that will and check it out...time spent can be relative in our field. the good way can be done just as fast when you get quick! im glad you got at least some tips...sorry for the debate...

Yer funny!:lol:

If you ready the instructions that come with pvc cement, they say to clean with primer. (e.g. https://www.oatey.com/ASSETS/DOCUMENTS/ITEMS/EN/howtosolventweld.pdf) That's the reason they want to see the primer.
Here in the Houston area... I have never seen anyone use primer, ever.




I used to cut sections of 2.5" and use as a slip coupling when repairing 2" underground runs from transformers. The POCO inspectors never said anything. Purple primer all the way!

I use 2.5 as slip repair coupling on 2" underground as well. Never have cemented it either, where is it going unless someone digs it up again?

Only time I have used primer is when I wanted to assure a better than usual weld. Doesn't help too much IMO if you don't also use a heavy body solvent cement.
