Upgrade 30-Year-Old System – Reuse PVC, Add Drip Later

30-year-old residential system. Reuse PVC pipe; replace valves and heads. Drip conversion later possible.

Drip Conversion

  • Drip heads adapt to existing fittings.
  • Add filter + regulator (30 psi) on valve.
  • Regulator prevents emitter blowout; filter prevents clogging.

Valve Choice

Residential Rain Bird DVF series—commercial parts cost more, last same. Good residential valve sufficient.
