I swapped a 50x80 ft block from wobblers to 0.6 gph pressure-comp drippers on 18 mm inline, 12 in spacing, and cut water use about 40% while reducing leaf wetness on lisianthus… Anyone compared Netafim DripNet PC vs Jain Turbo with anti-siphon on shallow slopes with well water at 140 ppm hardness behind 120-mesh disc filters — noticeable differences in clogging or pressure balance after a season? Looking for a durable, low-input setup I can fertigate through without gumming emitters, keep run times under 45 minutes at 12–15 psi, and minimize flushing labor.
I’ve run DripNet PC and Jain Turbo-AS on shallow 1–2% slopes with 140 ppm well water behind “120-mesh”, and DripNet kept tail-end flow steadier while the Jain picked up slime clogs faster at “0.6 gph” — , biofilm creeps in quick. If you’re staying with 120, add auto-flush caps and a single air/vac at the high point or do a monthly 1–2 ppm chlorine pulse; bumping to 150–200 mesh pretty much erased the clogging difference for us.
On our 1–2% beds, adding an air/vacuum relief at the high point of each zone cut Turbo‑AS tail‑end slime more than swapping emitters. > a monthly 1–2 ppm chlorine pulse; bumping to 150–200 mesh pretty much erased the clogging difference for us. Same here, but the vent stopped shutdown suck‑back and cured most of it even before we bumped mesh — do you have vents on the highs?
Quick example: On a 50×80 block with ‘0.6 gph’ DripNet PC on 18 mm/12" at 140 ppm behind ‘120‑mesh’, bumping the zone discs to 155‑mesh and doing a 90‑second open‑end flush at startup cleared the fine carbonate grit that kept sneaking into my Jain Turbo‑AS, and uniformity stayed steady; DripNet seemed indifferent. If head loss is tight, a short 3/4" flush manifold at the ends makes the purge quick without starving the line.
Auto‑flush valves at the ends plus a brief citric acid rinse every couple weeks finally cleared our tail‑end slime. DripNet stayed more even at startup, while Turbo‑AS only behaved once we “slow the shutdown” to avoid vacuum draw, per @jameson_p23 — like closing a door gently so dust doesn’t puff.
I cut emitter gunk by adding a 2–3 minute clean‑water ‘post‑flush’ after every fertigation so fertilizer doesn’t sit in the labyrinths; it made DripNet PC and Turbo‑AS run similarly for us on gentle grades. I also nudge the regulator a hair above nominal so the PCs pop open evenly — if you notice any suck‑back on shutoff, back it down; Netafim’s maintenance note outlines the timing: https://www.netafim.com/en/irrigation-knowledge/drip-maintenance/.
On a gentle 1–2% grade with 140 ppm, DripNet PC stayed uniform for me at 15 psi at the header with a single 3/4" air/vac at the crown; Turbo‑AS liked about 2 psi more to start clean. > if you notice any suck‑back on shutoff, back it down; Netafim’s maintenance note outlines the timing: https://www.netafim.com/en/irrigation-knowledge/drip-maintenance/. Agree on the timing — those settings stopped the post‑shutoff draw and cut the little calcium flakes in the last rows.
On my 60×90 lisianthus block with 0.6 gph on 18 mm, 12 in, the Netafim line held distribution tighter after I added a pressure‑sustaining slow‑open valve at the header (about 15 psi); the Jain matched it only after moving from 120‑mesh to 150‑mesh discs. With that well hardness, targeting about pH 6 during irrigation per UC ANR’s guide https://anrcatalog.ucanr.edu/pdf/21637.pdf kept mineral fizz out — startup burps drive me nuts. Have you tried a slow‑open valve at the header?
I’ve run both on a shallow slope with 140 ppm, and Turbo‑AS stayed clean only when I pulsed a mild acid every few weeks to drop pH; without that, DripNet PC was less touchy about carbonate flakes. Auto‑flush ends on each lateral helped more than the logo, but if you’ve got a low spot add a small air/vac there to avoid drawing fines on shutdown. “A little acid beats a lot of poking.”.
