Hello all, trying to get a “fix” for a poor situation. We moved into our house last February. After we bought the house, we realized the previous owners went “cheapest route possible” to “finish” the newer build with landscaping so they could sell it. Poor sprinkler spacing. WAAAAY too many heads per zone (averaging 8-12 hunter PGP’s per zone - literally all set to the default 2 nozzles regardless of spray pattern). Cheap rock. 5 valves crammed into a small sprinkler box with one sticking out of the side (seriously!). The ENTIRE perennial beds, shrubs and trees are on a single drip line. Anyways, I spent the whole year working through the flex daily schedule getting it running appropriately and after switching the nozzles to appropriate flow rates and scaling them WAY down to try to get decent spray patters, while also changing out the entire backyard to low pressure mp-rotators, I think I finally have the yard being covered… at least all of the grass is green.
Now that the backstory is out of the way for context here. I just had to do some maintenance on the drip line because I realized it wasn’t running at all (grrrrr). Something happened since I fired up the spring sprinklers. Well, while getting it back up and running, I realized that they used a mixed emitter system on the drip line. Aka 4gph DIG emitters on the trees, 2gph emitters on shrubs, and 1gph on all perennials… Anyone have experience on what might be the best settings to run this thing at? I realized I was probably WAY overwatering shrubs and trees last year as it was running for 1 hr or so 2-3x per week. I have decently dense clay soil as well. Feel free to ask me what questions I may be leaving out, but I was thinking of setting the zone up as “shrubs” with silty-clay as the setting and adjusting the nozzle rate to 1.5" per hour seems to be a ballpark average for a mixed system between 4gph and 1gph.
Thanks in advance for help.
