Im ready to open the whole can of worms with this thread. I have been doing irrigation work for the better part of my adult life. From starting out as a summer job in college 20 some odd years ago, to ending up making it a profession that has supported my family. To say the least, it's a very love/hate relationship I have with this field. It has given me the freedom to be my own employer, the workflow is pretty much endless 10 months out of the year without having to spend a dime on advertising, I have made a lot of relationships with good people in the field and customers and in all honesty it has given me the respect of a lot of people that depend on our knowledge and that is a satisfying feeling. For all the positives, the negatives are simply endless. I think most small business owning irrigators can relate to the fact that somehow this profession dominates almost all aspects of your life. Free time, forget about it. If you are lucky you can spend Sunday with your family a few weeks out of each month and cross your fingers that the phone doesn't blow up all day. Yet most of Sunday im itching to go out and organize our inventory, straighten up trucks, etc, etc. because I know if I don't, the upcoming week will be a cluster. It definitely feels like in some ways I made a deal with the devil. He gave me a profession that provides endless business, supports my family and honestly Im pretty financially comfortable. Yet the trade off seems to be, I had to give him every other aspect of my life. So enough about that tangent, im just kind of throwing it out there because im starting to wonder if somewhere in my mind im looking for an out because im getting older and my patience is not what it used to be, nor are my joints. Next venting topic! Threaded fittings and threaded valves. I have been working with them for 25 years and one thing I can say is they are terribly inconsistent. Threaded fittings are almost always on the pressured side of an irrigation system which just seems like bad practice in general unless you are dealing with copper and brass only. I hear the "hand tight" plus a half turn argument, which does not really seem logical considering everyones hand tight is considerably different. My 25 year old employee can hand tighten a fitting far tighter than my mid 40's hands. You have all these arbitrary warnings of "don't overtighten threaded fittings", yet they notoriously drip if you don't crank the hell out of them. We basically use only schedule 80 banded adapters, Toe nipples or brass adapters and that helps, but it's not a miracle cure. You have some fittings, valves, etc, that are plenty water tight with a fitting that only goes half way to bottom and then other that we have to bottom out. I had 2 cases this week alone of working with 2 inch PEB valves where both had TOE nipples pre wrapped with TEFLON. The only way they wouldn't drip was to completely bottom them out and this was at 85 PSI incoming pressure. We even alternated the TOE nipple with a LASCO schedule 40 2 inch male adapter and ended up with same result. Only way it wouldn't drip was to be bottomed out. Suffice to say this took multiple turns with channel locks as it required far more than hand tight and a half turn. Did I just get a batch of badly calibrated PEB valves, possibly, but that is far to common with threaded fittings and it's really annoying. Last venting topic! Manifolds and glue. One thing I can say without any hesitation is that the ABSOLUTE single greatest thing that an irrigation system can have is a Pressure regulator at the cross connection. This will save thousands of dollars in repair work over the years in fitting failures and valve failures. That said, far too commonly they are not installed and you can generally bet that when there is not a regulator, the manifolds are going to be slapped tight with 4-5 valves in a 17 inch valve box butted together. One pin hole in the incoming pvc manifold fittings and the whole thing is garbage. The whole practice seems so damn dumb, but it's almost the norm. I really do see the future of irrigation being high psi lock and release fittings on all PVC fittings on the main side. Obviously, it's hard to find any reputable push lock and release fittings for pressurized lines, but I would venture to say that this will ultimately change in the near future. We are still building irrigation systems with antiquated practices used in the 1940's and 50's. It's a service and repair heavy industry because overall it's just extremely poor practices that are still being used today. Sorry for writing a novel. I finally had some free time and have had a few frustrating past weeks. One thing that has become glaringly obvious over the years in my opinion is that almost all real problems occur at manifolds, threaded fittings or tap fittings where PVC cross connects to copper. Granted, we are only working with PVC here and not poly, but I assume it's all somewhat relative.
