    You should never need a dauber on pipe less than 1/2".

    1. Of course, if you looked at the link, you'd realize that IPS flex PVC doesn't come any smaller than 1/2".

    2. I wouldn't bother using it in place of funny pipe. It's great for particular situations, so I keep it on hand.

    1. The link you gave said "Used as flexible swing joints or risers"
    2. I see now but have no use for it.

    Thought I would give one of the Rain Bird PRS DIAL deals a try in the zone I tested before that was in the nineties. Pressure is down, reading about 46 at the head. Setting it up by the instructions you increase the flow at the flow control (from fully closed) to within 15psi of what you would like to have. Then adjust the the gauge on the PRS DIAL. I opened the flow and read around 60 then turn the dial to around 40-45. The picture shows the dynamic now. Not sure of the principle, but the flow control is way down. Could I have achieved the same thing without the device? I'm afraid the valve is going to close too fast now, but maybe the dial thing will help with the shock. I still think the correct fix is a regulator. John Deere has a wilkins 600 for around 400, so that plus a master valve and wire then labor. Working on that bid now.

    Man, I was getting hit from both sides (1812's) even at the new lower pressure, very wet. It's a strip bed and I had the two adjacent ones turned while doing the install, but back in the proper orientation for the pic. Sorry
