Blumat Flush System 4-Way Valve

SKU: IG15943


This is the heart and soul of our Blumat flush systems - the 4-way valve. Rather than ordering all the extra parts and following a complex system, use this valve and customize your own. You can add several drip stakes for larger pots and use this in many different ways. This kit comes standard with fittings for 3 connections: one 3mm, one 1/4", and one 8mm for the supply line(s). NOTE: You can request different sizes or configurations for no extra charge.

Our flush systems allow you to flush your plants, a necessary process for those adding nutrients into their system. Flushing removes excess nutrients and debris from from your supply line. You can also use a flush system to add thick nutrients and teas without clogging your Blumat sensors. Our flush valve has 4 settings: all closed, all open, one direction open, and the opposite direction open.


  • Flush your plants
  • Add thick nutrients and teas without clogging your Blumat sensors
  • Clean out algal and bacterial slime, as well as sediment, from your supply lines
  • Blumats won't allow water to flow until your potting soil dries up, which means the supply line gets flushed, not your soil. When adding tick nutrient or tea, simply turn the Blumat side off, letting the mix flow solely through the flush stake. When cleaning your lines, simply leave both sides open. This system includes everything except for a Blumat sensor: a valve, adapter fittings, tubing, and drip stake.
