NDJ 16mm Automatic Lateral Flush Valve by NaanDanJain
Keep your driplines running at peak performance without lifting a finger. The NDJ 16mm Automatic Lateral Flush Valve purges sediment and debris from your system at the start of every single watering cycle, eliminating the need for tedious manual line maintenance.
Debris build-up is the number one enemy of drip irrigation, leading to blocked emitters and patchy watering. The authentic NDJ Lateral Flush Valve solves this problem completely by opening wide whenever the system turns on. As water surges into the line, it flushes out accumulated silt and fine particles through a large internal water passage before automatically sealing shut as the pressure builds. It is an absolute game-changer for both surface and subsurface 16mm irrigation layouts, especially in areas with poor water quality or high mineral content.
Why Upgrading to an NDJ Flush Valve Makes Sense:
- Labour-Saving Automation: Completely replaces the manual chore of walking your zones to flush line ends every couple of weeks—the valve takes care of it automatically.
- Smart Flow-Reactive Action: Unlike primitive valves that rely solely on high pressure, this advanced NaanDanJain design reacts dynamically to water velocity, ensuring a thorough purge before sealing.
- Corrosion-Free Construction: Engineered with zero metal parts, using premium, chemical-resistant polymers that won’t rust when exposed to garden fertilisers or harsh winter conditions.
- Tool-Free Maintenance: The simple, robust internal structure can be quickly disassembled by hand, making it incredibly easy to clean out or winterise ahead of seasonal frosts.
- Snug 16mm Barb Fitting: Connects securely into standard 16mm polyethylene drip lines or porous soaker hoses without requiring messy glues or complex clamping setups.
Where to Use It:
The NDJ 16mm Lateral Flush Valve should ideally be installed at the lowest point or the far end of every individual watering zone. It is highly recommended for domestic hedge driplines, allotments, vegetable beds, and commercial greenhouse misting layouts where consistent emitter output is critical to crop health.

Trade Pro Tip: For absolute security on high-pressure domestic mains setups, use a small snap clip or heavy-duty ratchet clamp over the 16mm barb joint to lock the drip tubing firmly in place.
Frequently Asked Questions:
Where should the NDJ lateral flush valve be installed?
For the best results, you should install the NDJ automatic flush valve at the lowest point or the very end of your 16mm drip irrigation line zone. This is where sediment, silt, and mineral debris naturally settle. Putting it at the line end ensures the entire lateral pipe gets completely cleared out during the purge cycle.
Does this automatic flush valve reduce my system pressure?
No, it does not drop your running pressure. The valve is designed to open up only at the start of a watering cycle when the zone is filling up. It remains open for roughly 15 to 25 seconds to purge any dirt. As the water velocity builds up and reaches normal operating pressure, the internal mechanism automatically snaps shut, keeping the system perfectly pressurised.
Can I use this valve with subsurface drip lines?
Yes, the NDJ 16mm automatic flush valve is highly recommended for subterranean systems. Since you cannot easily see clogged emitters underground, installing a reliable flushing valve ensures that fine soil particles and sediment are purged before they have a chance to block up your embedded drippers.
