Hey no problems. Just make sure you're getting Rainbirds top of the line products. Not what they sell at the home improvement stores. Frankly, to put it mildly, Rainbird has marketed a lot of "CRAP". The name Rainbird used to get a lot of respect from me. Now I view them as just another company trying to increase profits at the buyers expense. If you're using spray heads, make sure he's using the 1800 series. If not, he's trying make an extra buck at your expense. Once again, good luck!
If I can't fix it, it's broken!
