I've decided to connect the irrigation in each bed together, so that it forms a loop and is fed from a single water source - to accomplish that, I've got poly connected to the each dripline, running down the edge of the garden bed, across to the next bed, up the edge of the next bed and connected to the next dripline, and so on...hopefully that makes sense! So in essence, I've got 4 separate dripline setups at a height of about 40cm, and then a bunch of low points between the 4 garden beds. I'm going to install an air release and flush valve, but my question is, do I need to install air release valves for each garden bed (because they're all high points in the system) and subsequent flush valves in each of the low points? Or, will a single air release valve and a single flush valve be enough? Re: Drip irrigation setup - air release and flush valves 2Nov 17, 2011 7:50 pm That will work. The tough thing with this stuff is that in a grid it is really hard to work the soil when you need to. The end result is something that isn't so practical. So run just one header in each bed. Use the netafim miniscape 6mm lines. 250mm apart. just fold the ends and slip some 13mm poly over the end to seal it up. This way when you want to work on the veggie bed, you flip only a few pipes back over the side and out the way. Every now and then, when you do pull the lines over the side, slip the poly sleeve off and flush them out. At the end of the poly header line, have a brown flush valve. Best to have that in the bed or further along and under a tree. Install a grey vacuum breaker at the highest point anywhere along the line. Should ideally be 20-30cm high above the high point so on a 300mm riser will be perfect. Use agricultural fittings for that rather than the slightly cheaper domestic retic ones to get a good seal. Both those are great insurance on protecting the system. At the head of the line should be a filter then a pressure reducer. The unit normally clips into a metal plate screwed to the wall, either plate is not flush, or unit not hooked in and could be hanging from the pipes partly, either might… 2 16744 Okay, then the choice is really about the build quality of the door itself which means the brand name. Sorry I can't recommend one or the other so best to rely on comments… 5 4140 Hi there, looking to have a gym in a new build.
