Repair coupling (aka slip fix)

May get called for piker repair, but here it goes. Contractor parks on valve box and cracks lateral just out of the valve. Excavation reveals intersection of previous repair with two repair couplings. Pipe is deep enough, so cut the pipe just past the crack. Flip the tee over and build a saddle. This is one of those times when you do want to bury your work. Made sure to really pack it tight to limit any movement and cut the box opening for plenty of pipe clearance. You don't see double slip fixes very often, but this time it worked out.

Union + toe nipple would have made that repair 100% cleaner IMO.

Obviously, the valve box should be supported, even if you have to bring in bricks or blocks. Is that a corroded/busted flow control on that W*M valve?

Maintenance man likes to turn the flow control down to close valves for whatever reason. Now he needs pliers, he found the manual bleed lever too. A little knowledge can sometimes be bad.

Yes, very much clay. Could make a cup or bowl with it I'm sure.

Good point, I don't carry the toe yet. Had to reduce this one 1 1/2 to 1 1/4, so would have needed a coupling and might not have had the room. If your talking about a threaded union (with the o-ring), I don't have much experience with those. I see them in pool stuff, but rarely irrigation around here. Maybe pumps or an occasional RPZ that a plumber installed.

a good friend of mine works for the school district and is in charge of the turf maintenance. he has chosen to install a union on the pressure side of the 2" valves and a slip fix on the lateral side. they replace these valves at least every 2 years.

That would make the switch easy. I sometimes see a ball valve ahead of the valve here, the city does that. Makes valve work easy because the main shut off may be a great distance from the valve. From the repair side the union seems a little tougher because your distances have to be spot on and sometimes the pipes don't line up either. My experiences are jaded because I'm cutting out the union that wasn't done properly. I'm not anti union, they just don't fit most of my situations.

Why every-two-years valve replacement? Can't they install a reliable product?
