MICRO-IRRIGATION ACCESSORY
4 mm check valve — essential protection for your irrigation and aeration lines
This BloomLED inline check valve pushes in seconds onto any 4 mm ID / 6 mm OD soft tubing to block water or air from flowing backwards. A must-have between an air pump and a submerged air stone, between a hydroponic reservoir and a dripper rail, or on any setup where parasitic siphoning could damage your pump or flood your grow tent.

🌱 Instant anti-siphon
Protects your air pump from water creeping back up the line and your reservoir from draining out when the pump stops. A discreet insurance that prevents many indoor-growing accidents.
💧 Tight seal both ways
The elastomer membrane opens with the slightest forward pressure and reseals hermetically when flow stops. No parasitic leaks, negligible pressure loss.
🔧 Tool-free install
Push it on, it clips, it holds. An engraved arrow on the body shows the flow direction at a glance. Removable and reusable as often as you like.
Which tubing and pumps is this valve compatible with?
Any micro-irrigation soft tubing with a 4 mm inner / 6 mm outer diameter, compatible with aquarium-style air pumps and standard 4/6 mm coils on the market, including the BloomLED Siroflex coil.
How do I install the valve the right way around?An arrow engraved on the body shows the flow direction: it points to the outlet (drip emitter or air stone). If flow doesn't pass after install, simply flip the valve.
The pro accessory that protects your pumps and reservoirs from back-flow accidents — for just pennies.
