    It must be the no-primer swipe and slam procedure the fine technicians at the unnamed national contractor use.

    Good for my Repair business though.

    Why make glued manifolds? Threaded tee's make replacements easy. Manifold "union type" tees are even easier.

    Do you guys use these? Swivel tee's and elbows with the O-rings? No glueing, no tape and very easy to service.

    Those swivel connections look like future maintenance and repair items after the O rings have degraded.

    Good thinking, where can I get those?

    I've had some in the ground for 15 years with no problems. Yes there are some that have had problems, but I've also had PVC manifold tees that crack at the seams due to failure. Every product will have some failures.

    I forget which of the swivel tees has the bigger, beefier o-rings - DURA or Spears.
    Great products for easy maintenance.

    I love the swivels. I haven't had any fail on me after about 10 years of putting them in, but even if they did they are easy fixed or if a valve has failed it is very easy to replace it. Much easier than pvc. When going to repair a pvc manifold I just curse and wish they would have installed these. You can change a valve in 5 minutes and don't have to worry about draining the system and waiting for the glue to set before turning it back on.

    Gluing in a valve, is like welding the spark plugs into the engine. :hammerhead: Then the customer has to pay a lot more to change the spark plugs (drill and tap). Customer not gonna be happy about that. :nono:

    I honestly cannot remember a valve body going bad and having to replace the manifold.
