    Forgot to include one with the boot. I'll try to get a pressure check later today if possible. One of my customer is having a fence replaced and the contractors are doing their best to hit everything in sight, so a little busy. I showed the fence boss where the two DCV's were. They are manifolded into a 2 1/2" main and will make a big mess if they hit it. No wire in the main ditch there so I can't trace it. Fingers crossed today.

    I think they'd have been better off with standard swing pipe

    They all seemed to split at the side mount, how odd. Either pressure or freeze, or a bad batch. Nice boot shot.

    Do you have trouble sleeping at night?

    I have a guy in my area who does this to the extreme. Choking down a #9 nozzle that throws 40' to cover a 15' area. All I can do is shake my head. The sad thing is he does way more installs than I do due to, I figure, a much lower price. Which he can do by dogging 2 pgp's to cover a 20' x 60' area while I am using 8-6" MP Rotators with check valve. Sad but true. I do get a lot of service work on his systems due to the fact he will not service them. I figure he gets complaints about dry spots and can't solve them due to the poor original design, then he just stops answering their calls and blows them off.

    "He never returned our calls" was the most frequent line for me. Sadly, some had failed right out of the box, and nothing much could be done to fix them.It's not fun to have a client cry in front of you. :cry: On those 1812s, I'd be curious what the factory has to say about them, sure is screwy.

    If it's in an area with low head drainage/or has sams installed and sticks out of the bed some or is in a retainer box with sandy soil it will freeze and crack. We don't blowout systems in Texas so a hard freeze is going to cause damage under those circumstances.

    Here's the pressure check appox. 106 static and 97 dynamic. I've seen heads split from freeze, but these were at grade or below, plus we had a light winter. Pressure needs to be controlled for sure.

    I think you've found your problem right there. Plus consider any surges. PRV would be first thing to add in my book.
    But it does seem odd to me, especially if they all split in the same place. Seems like a weak spot to me.

    75 psi is mfr rating, so they're off the hook - maybe a PRV module can be added to the master valve
