Lots of insight in to the process. I have been the one digging for the past 20 years, now I am doing the work you just showed us. Thanks for your instructions. 10 times is a good time!
It’s amazing how the glue will give before the gasket will dry rot. I remember installing the old hydraulic systems and then going back and redoing them to electric years later. I designed my system with a make shift valve in head on my yard. The 4” and 6” slip fixes suck when your by yourself. Best device made for repairs
I always say when I do irrigation repairs at my golf course, do it once do it right and that isn’t the way to do it especially with it not lining up. Never use expansions or else you’ll be digging that hole again.
Yes there are a few ways to do the repair if time isn't an issue and not hand digging by yourself lol. I know one of the brands of expansion couplings is notorious for cracking but these ones are good. The irrigation system is over 25 years and has maybe 100 of this type of repair with good success. Of course not as good of a repair without an expansion coupling. Thanks for sharing and post some of your repairs if you can.
Glue the tee to the telescopic coupling before dropping in hole. Will help to measure for full extension of coupling. Also make the last connection at the tee ( most exposed part of your excavated hole )
Good video for beginners. This is not a job for two people though. Maybe having another guy for 1 minute to push shovel on pipe while you glue up the final connection but usually you can just expose another foot of pipe in
Aren’t you concerned with the pressure on the telescoping coupling? it seems that if it isn’t straight, there’s a possibility for a leak around the O-ring.
If I knew it wasn't straight, I probably wouldn't have used it. I've never seen this type of telescopic coupling fail before, but I guess time will tell.
Unfortunately you'll be back doing that repair again, telescoping repair couplings are sketchy at best and useless if any deflection is present. I stopped using them long ago, Harco ductile iron is the way to go. No glue and good for ever. I have maintained 36 holes of irrigation alone for the last 22 years and have nothing but good to say about the ductile. Compression couplings and telescoping couplings I have done and redone again, move to ductile, fix it once and you never return. FYI I use ductile on 2" all the time, my go to for all repairs. Shut the water off. Cut pipe out, glue in new stuff slide ductile coup with rubber gaskets on the pipe all the way and glue the last piece in and then pull the coup back on the pipe and center it and your done, turn the water back on when your glues set and done. Also the Elbow at the bottom of the swing joint needs a small cement thrust block to to take the load off that pvc. Cement and ductile repair coups and pipe lube will make your life easier in the long run. When I learned of them it changed everything. Good Luck
Great to hear about your way of repairing, Sounds pretty solid. I'm limited to what my supplier has. I have replaced some of this style coupling before that have cracked at a union but this type seems better. I worked on coures with hundreds of 2 inch repair couplings in, but not anymore 🤣
I’m pretty sure he knows what he’s doing if he’s never had 1 fail on him , everyone has there own way of doing stuff geez way to bring the negativity in here though your probably good at that

It's good to be off the shovel, I'm sure.

Yeah, the big slip fixes are definitely a fight. You can bolt on a riser clamp temporarily to give you some pulling power.

Haha, I need a laborer to prep for me.

We’re they running a 2 wire system maybe baseline ?
No, not a two wire system. One wire for every two heads.

In our area they crack from sandy soil and earthquakes. 38yr old pvc gets brittle.
38 years is a long time. Must be some good glue joints.
Have you ever thought about using the steel coupling,from smith & Blair product made in Dayton Ohio. I work on 6”to10” irrigation main line.
No, I'm not familiar with the product. Big pipes you're working on.
He said he never had a misfire....
this happened to my water main to my house. a 2 year old 90 degree elbow leaked. The materials are ridiculous
That sounds like an issue with the workmanship, not the product
i feel like that line failed because the pipe is so flexed creating too much pressure on the connector.
