Your input

There is a 2" Main Line with a bad glue joint on a bell ending Just about 2' down.

There are 2 - 1" Lateral lines rubbing against the main along with wire.

The psi is 125 ( We have recommended a PRV, but the issue is some of the zones go up roughly 75' vertical feet)

It's either, Telephoning the main ( 4 - 2" 90's) . Or Telephoning the 2 laterals away from the area to slip fix the main. Our biggest concern is that if the telephoned main line was ever to blow it could cause a lot of damage to the area and cost.

We also have suggested a Master Valve.

I believe we are going to telephone the laterals to slip fix the main, who wants a slip fix on a main? No one of course

i personally wouldn't slip fix a main line, you (in my opinion) can get away with them on laterals in some cases but a properly fixed glued joint will be far better and on a main as you're describing... slip fix is risky.

Go to a waterworks store or similiar and get some mechanical couplers. It's what water utility companies use when repair water mains. Little expensive, but it gets the job done and you can turn the water on immediately as it relies on gaskets.

Instead of slipfix, look for some dawn Kwik Repair couplers. I'd trust them before a slipfix.

I don't know others experience.

But I would trust a slip fix before dawn products.

I would use a pair of unions over a slip fix any day of the week.

Then you have this.

If you have class 200 (or less, gawd forbid), unions would be my choice. The Ford pack joints work super; are pricey and can only be used with sch 40/80 pipe.

You know.... I've never understood the dislike of slip fixes. I've slip fixed 3" mains with no problem. In my day as an irrigation tech I know I've personally slip fixed at least 40 to 50 different main line breaks and never had any issues with the slip fix failing. I think people just don't install them properly and eventually have problems with them. They have to be fully extended and installed perfectly square to the pipe but other than that they work great!

I have used slip fixes on mainline quite extensively up to 3" too. However, there are times when there can be no downtime and the system needs to be brought back online as soon as possible. There is no way you can do that with a glue joint and expect it to hold for a considerable amount of time. With a pack joint or mechanical coupler, you can turn the water back on quickly.

The largest that I deal with is 2". I have been using PVC compression couplings on mainlines and PVC slip couplings on laterals. No problems to-date (2 years). Should I do something different?

I did not know that slips needed to be fully extended. Do those of you who use slips adhere to this?

Thanks again for your continued help!
