so a few times per year I have a some Rainbird 42sa's that just quit turning. they still spray water but will just stop turning. I have taken them apart and cleaned them but they might work for a minute or two but they just stop turning. it normally just two out of 5 zones that I have issues with. everything else seems to work as it should.

i am on well water for irrigation.

I had a 52sa that started this same crap last year. I eventually gave up and replaced it with a PGP.

It's either a problem with pressure or your well-water comment stood out to me. Does your water have a lot of minerals such as iron, etc.? Could require an upstream filtration system. Otherwise maybe you need pressure regulation on other heads - if this head is far downline from the source, for example.

yes the water is hard for sure. there is iron in it.

I do have a pre filter installed on the well unit. It isn't a very big pre filter but it does catch the sand and other sediments. I do flush it about once a week.

the strange thing is that these two particular zones where the problem occurs are the furtherest from the well head.

that was going to be my next step as in moving to another sprinkler head.
