I have redone my drip irrigation system. Since the old one way was so labor intensive I added a timer, pressure reducer, and filter. Question is that my system seems to have a bit of low pressure. By that I mean the sprayers don't spray very far once I extended the area. Can I cheat a little by taking off that pressure reducer? I checked at the hose bib and I believe it read 80 psi. The manufacturer suggested adding another zone to the mix via the little handbook that's available at the store. Also they recommend a maximum of 220GPH. But it seems to make since doing this to me. Any suggestions?
