I'm with you! But I question the product documentation that says it can control zone pressure as well as flow. If you have the time, the product manual is on the SW website under HPV Valves the model 101. Let me know if you read it differently than me.
Anyone installed the LD0912-100 Rain Bird Landscape Dripline or simular product under turf grass? I understand it can get clogged over time. I was interested in using it some narrow parkways.
Thanks, I understand the difference between pressure and flow. I am guessing the adjustment must be linear since there is only one adjustment knob. The manual clearly states <i>faciliates zone pressure control and flow management, additionally the tech info says 20 to 150 psi</i>. I was just trying to figue out if it could be preadjusted adequately to keep from over-driving the zone. BTW they were only $2 bucks more.
The installation manual does'nt provide any details on proper adjust of the pressure/flow adjustment feature? Do you have to use a pressure gauge initally or just guess?[] I am feeding some drip sections and need to keep the pressure low.
