like pour gasonline on the lawn,light a match and burn it? then just spray it out with a water hose?
try burning incense or strong scented candle.
I'd use the three/four inch lines, until your budget is quite that tight. That quarter inch difference will provide you with 2.25 instances as a lot water on hand to your sprinkler heads. In observe, it won't make that much difference, but assuming that the pump can give that so much water, and the sprinkler heads can distribute it, why not make the section that's the hardest to replace - the portions you bury underground - as massive as possible? That approach, if you want to improve, or you will have a spot the place you want one more sprinkler head later, you do not ought to tear up the whole procedure to do it. Also - I would appear at using whatever as opposed to PVC - like these coils of flexible black plastic pipe. They are made to be buried, they are seamless besides where you reduce it, so you will have fewer advantage leaks. Plus, you could go even better - say a one inch line. That maybe overkill for what you want, but at worst it'll imply that the bottleneck in the system will probably be at a point the place you can get to it simply if you wish to trade it.
