SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Just my personal experience with the Maxi Paws...they are a HEADACHE. I have a system that had 23 of these impact heads, i ended up replacing them with Rainbirds 5000 plus rotors. Too much maintenance (cleaning) with the Maxi paws...kept getting stuck, they would not trip the return mechanism. I blamed it on low pressure, so i reconfigured my system (less heads per zone) this increased my pressure to about 45psi, i still had the same problem, not as often, though. I ended up pulling all of these heads off and replacing them with RB's 5000 plus rotors, this ended my dilema. I use to have to babysit the watering process, make sure i was there so if a Maxi paw got stuck, step on it. There is plenty of people on this site with knowledge way beyond mine in this matter...this is purely personal experience's with these Maxi Paw impact sprinklers. I DONT recommend them.

I am going to agree with Oscar here, I dont recommend the Maxi-Paw for the above stated reasons. Either the Rain-Bird 5000 series, or the Hunter PGP sprinklers, they are both good sprinkler heads.

use rainbird 5004 (period) Do not use any other .

It's kind of late to ask questions, if you've already signed a contract. Get the 5004's - they can be fitted with Rain Curtain nozzles, which achieve a very good spread of water at low pressures. It is true that a Maxipaw can throw water further at low pressure than a gear drive rotor can. But that only means possibly using less sprinkler heads, not a better sprinkler system. You probably want no more than forty feet spacing between heads on your pressure. The installer might have been planning for more distance between heads, and priced the system accordingly. If so, he might want additional money for more heads and zones, and would be justified in asking for it.
