    I don't deal with 5004's much at all. Mostly see PGP's. For some reason Hunter is the most used in my part of the world.

    Anyway, strictly speaking about wiper seal life/failure what do you see in 5004's versus PGP's? Plastic not metal.

    Just the wiper seals. Nothing about distance, spray angles, lobster dinners, hats or dinner cruises from the manufacturer.

    I just replaced 10 PGP's at one residential place due to wiper seal leakage. Date codes from 1999 and 2000. Pressure was poor due to all the combined leakage on 3 zones.

    This was in very sandy/gritty soil. Shafts all scratched up, scored. Two-thirds of the heads were also too low in the turf. Some near the driveway got run over and pushed down. Others I'm thinking the turf roots "grew" higher over time.

    I get a lot more prolonged use out of 5004's on temp systems. There are always leaking issues with the PGP's. Also it would be nice if they freaking screwed the riser on tight enough from the factory on the PGP.

    Seems like a temp system is good testing grounds for products because you can see where the hydro seed is growing and where it isnt. Also they are above grade so small leaks are easy to see. Also temp systems get beat up pretty good by foot traffic so over time you can find out which is better.
     
  3. I know PGP leaks were becoming a beating when I left. What little I used the 500 I was very impressed. Love the fact they have LA nozzles on the tree and a small screwdriver for adjustment. SAM/PRS 5000 was an awesome head. Longevity I can't speak for.

    I see more water leaking at the seals on the 5004 than the PGP, but I prefer everything else about the 5004.

    PGP's are terrible. Not sure about the Rainbird heads. We started using strictly I 20's about 3 years ago, very pleased with performance so far. The only thing PGP's are good for is making $$ upgrading to I20's

    For some reason when I see 5004 I see a crap head.. When I see a 5004+ Sam head I see dependability and high quality.

    pgp a crap head - pgp utlra dependability and high quality- same with i20's.

    The i20's are awesome. Spray patterns were incredible, I just wish more people were willing to pay for them.

    PS- They just paid us to install, they wanted to do the clean-up to save money.

    In all reality , a 20 heads job is what $105 more? I dont sell em with installs but they are sure are nice heads. Thought about it before.
