Low Pressure at Drippers – Pressure Regulator Likely Faulty

Drip system worked 1 month, now low flow at all emitters. Hose bib pressure normal.

Test

1. Remove pressure regulator.
2. Run valve—if pressure good, regulator failed.
3. If still low, check anti-siphon valve for restriction.

Anti-siphon valves usually leak externally if faulty.
