    I don't even know why they make a pgp, how much more does it actually cost to manufacturer an I-20? 30 cents? Its like buying a lexus when you could buy a Toyota... same f''''ing thing.

    Do you really like the slip clutch? I think that may have the potential to backfire.

    I do really like it. I haven't seen any real negatives out of it so far.

    The original clutches, such as on original fixed-arc Hunter rotors, or Rainbird R-50's, or even the redoubtable Safe-T-Lawn rotor (man, that head had it all!) are great "harm-proofing" - the new 5004 clutch might bring on callbacks.

    You are correct about the pressure part. That spring is very strong and I wouldn't use i-20's on unregulated systems with really low pressure. That strong spring is really a blessing though. Over the long haul, the I-20 is going to have a lot less issues with retracting problems than it's cheaper family mate. Also does a good job of checking off without muddying up the head with pooling drain water on new installs.

    Not really sure what this means. Specs say the rotor is built to withstand a max pressure @ 100PSI. If in reality it is only built to withstand a max pressure @ 50PSI, then I would think that is false advertising. Regardless, you shouldn't be running a PGP, or any mid-range rotor, much higher than 50 PSI to begin with.

    Depends on the site. If I had excessive pressure, I would personally lean towards a pressure reducing valve.

    I was just referring to his personal experience with pgps.

    I read your link. Lets say you have a 5/8 meter, would it work to install a 2" prv? That would give you the greatest range to manipulate the pressure from 0-160. The other smaller prv's seem to have less flexibility.

    Yes, but why would you do that? Not sure where you are getting your numbers from but the regulating range on the DW series valves is 5-100 PSI, and the 2000 series 5-125 PSI, regardless of size.
