I guess I should have asked this question before I remodeled my system, but it occurred to me as I was gluing up the last few joints. I added about 350 feet of pressurized main line to my existing system, which was working nicely. Will the additional pressurized line have any effect on the overall operation of the system? It would seem to me that it would not have any effect, but I'm not a hydraulic engineer...heck I'm not even an irritator. Have I screwed up or am I creating a problem in my mind that doesn't really exist? I'm going to open up the system, flush the lines and test everything tomorrow, but I thought I would give you all a chance to tell me what I might expect.
