Inline Drain Valve - 3/8"

$30.00

Add a simple way to empty your misting line. This 3/8″ inline drain valve lets you release water after use or before storage. It helps protect parts and keeps starts fresher.

What This Valve Does

This valve creates a controlled drain point in your line. Open it to let water exit a section or the whole run. Close it to return to normal operation.

Why Choose This Valve

Choose this valve when you want easy draining with a quick, manual turn.

  • Helps reduce freeze risk in cold weather
  • Fresher starts after storage or long pauses
  • Easy service point for maintenance
  • Quick install in a straight run

Compatibility & Use Cases

Place the drain valve at a low point so gravity helps clear the line. Add one near the pump or at the end of long runs for fast emptying during shutdowns. For adapters, mounts, and filters, see Misting Accessories.

Care & Maintenance

Exercise the valve a few times each season. Keep the outlet clear of debris. Inspect seals and joints and replace worn parts if needed.

Troubleshooting

  • Light seepage at the outlet: Close fully and reseat; check seals and fittings.
  • Handle hard to turn: Depressurize and apply manufacturer-approved lubricant to the stem if applicable.
  • Slow draining: Confirm the valve is at a low point and that the outlet path is open.

Related Parts & Upgrades

Pair the drain valve with parts that keep water clean and flow steady.
