    so i'm in a bit of a conundrum. we put in a well many years ago for one of our typical high-end homes. can't quite remember the specs but it's a good volume system, using a 2" main because of distance and I think a 3 horse pump. Anyways we of course don't use pressure switches / tanks because I like it simple and always zone accordantly and put a pressure relief valve on just in case. well the owner used us for maintenance for a while then got cheap and used a competitor, he's now seen the light and come back. while he was with the dark side they added a drip zone, which i of course never use. but regardless, they added this zone and did it by:
    cut main (2"), add 1" drip valve, and then a 3/4" stub for the drip line to attach to. then they ran a butt load of drip tube. long story short it's not using 1/8th the volume of water this system wants to push and then to make matters worse it's pushed up so much pressure it's blow at a elbow a couple of times. I upped the size of the pr valve but now the drip valve isn't getting enough pressure to run the stupid amount of tube. what to do? I know in my heart that the zone is trash and I won't be able to get it to work, just looking for some ideas first. I've got a higher pr valve coming to be at 100psi instead of 75 but that's still a stupid fix to me.

    Can you use a Cycle Stop valve? Can the drip run concurrent with any of the zones?

    A prv at the drip valve might work, a cycle stop will screw your other zones.

    that's what i was thinking, then i just have to install a drain line for it.

    What's the mainline pressure?

    Or a gravel-filled drain pit.
     
  7. Convert all the drip to RB 360ts spky. Those use a bunch of water. Even if they have netafim drip just poke them in and add sprayers. Spike sprayers everywhere. Customers lov'em.

    Ok here goes Ill light the thread right up and give people reason to scream at me.
    Install 3 valves for the drip all going to the same zone . Wire each valve to another rotor zone . Flame away boys.
     
  9. No flaming here but why not just have three pipes dumping the water back into the well? Don't know anything about wells so I'm assuming it would be like putting water back into a lake.

    Why not run the other zones at the same time as the drip? Keep the drip running constantly while the other zones are watering. The ICC allows SCH D to run concurrently with other schedules.
