What is your opinion on the clamp on PVC repair sleeves?

I haven't used any, but I'm thinking about it because we have a lot of pipe damaged by contractors and sometimes our mechanics digging.

I pulled out 3 sets of wires today, repaired the conduit and pulled the wire back in. Wire not damaged, megged. I had another one that I could not find where it originated or terminated, possibly abandoned since there was no power on it.

I'm thinking about going by the supply house tomorrow and get one to patch it.
 
I've used several of them, and they work quite well. My only suggestion is to supplement them with band clamps (either Band-It's or "radiator clamps") around the outside in several places.
 
Call me old fashioned but I usually just file the stop out of a coupling . Repair the bad section by cutting it out and replacing it with a section and 2 new couplings one of course filed out so it will slip until you glue it in place.

Yeah, but you still need to repull conductors. The split repair sections are split long-ways, so you can leave the conductors in place. The trick is getting a square cut on the ends of the existing conduit without nicking the conductors.
 
The trick to getting square ends on the pipes is to use a tubing or small pipe cutter. The kind with a wheel...
Use a machinist's reamer [hook] to clean the inside sharp edges.

Great. While you're digging an extra couple feet out from under that 3" PVC, I'll have already carefully cut around it with a hacksaw blade or string saw and be mostly done with the repair. :cool: I like to cut almost all of the way through, all the way around, with a string saw, then rap it sharply with a hammer and it'll normally break off nice.
 
I've only used them a couple of times and perfect if the wire is not damaged and you don't know where they are terminated to pull them out.
 
Marc,
No one said that this was a 3" diameter conduit.
The small, "close quarters" tubing cutter will cut up to 1 1/8". It requires about ~6' of clearance.
A medium - up to ~2" - would require more space, maybe a foot, but not that much. After all, didn't a back hoe cause this problem?
Your problem is you don't have enough tools. For the larger tubes, you should consider something like the tight quarter, 4 wheel, Ridgid 44-S or perhaps the red Ridgid 226 In-Place Soil Pipe cutter [capacity = 1 1/2 - 6"].
{Why do the plumbers get all the heavy duty tools and fittings?} :confused:
