    I'll be doing a new install working off a 2" meter with 65psi static. 2" mainline, 2 and 1 1/2" valves. I usually work with smaller diameter pipe 1 1/4" down with 1" valves. What tips & recommendations do you have when working with larger pipe systems vs. smaller?

    Good primer and glue application practices, straight cuts, chamfering and seat the pipe all the way into the socket.

    You'll know where to thrust block.

    I feel primer application is the most overlooked part of the weld. Take the time to soften the pipe enough to allow proper penetration of the glue.

    PVC sockets are deeper and tend to push out when putting them in, make sure the pipe goes all the way in and hold the glue joint for a bit to make sure it doesn't expand back out.

    Larger pipes mean larger liability to possible damage. If it's commercial suggest a master valve and flow sensor

    Make sure your design is sound. If you are trenching use straight angles as much as possible. Larger fittings cost more and add up quickly if you need to keep using extra fittings.

    Don't cheap out. Some people can get away with going cheaply on a resident system and no one will know of any consequences until years down the road. Stick with good products and make your installers ensure they are taking the extra step to do a quality job instead of slapping it in

    If you're going to have a long main line, consider upping your main to 2.5" or 3" Also, Extra wire runs are a lot easier to do now than later....

    Make sure you wait for the glue to cure before you turn on the water or you will end up like my guys on Saturday. We added 2 zones off a 2" main, I told the guys glue the manifold up first then build the zones. They did it the other way and the 2" elbow blew off while my guy was wiring the valve. I would have been more pissed but it soaked him and I think he had to change his underpants after that.

    If the job was specced , your dedicated spare wire would be blue. Something to consider.

    One tool I always missed having at hand when I needed more force to seat a slip connection was a big rubber mallet.

    do yall bevel every single joint?

    i used to bevel nothing at all, but lately: everything.

    The time difference, in my opinion, is whats the "real" nessesity (or lack of it) for all this beveling?
