OK, in the past I have used a large tow behind compressor maybe a 185. The rental company screwed up the reservation and we ended up using a small tow behind maybe a 85. I did two larger sysetms with long pipe runs today and I was not happy with the results. The compressor did seem to blow all the water out but the heads did not pop up all the way, some did and some didn't. I went through some zones twice to be sure. Should I be worried or will they be ok? I don't really want to do them again but I will If I have to, what would you guys do? Each one took me two hours.

If you open a valve with a good charge of air, and you don't see any water at all coming from the heads, you probably got it all. If you are working on a main line system, you can manually open the main line, and use it as an 'air reservoir' and get an extra push each time you open a zone.
