DESCRIPTION
Automatic Venturi Fertilizer Injector System
Feed your plants exactly what they need, exactly when they need it. This Automatic Venturi Fertilizer Injector System uses the Venturi effect to draw liquid fertiliser straight from a reservoir into your irrigation line as water flows through — no electricity or moving parts required, and virtually maintenance-free. Ideal for greenhouses, polytunnels, raised beds and drip irrigation setups, it takes the guesswork out of fertigation and ensures every zone gets a consistent, evenly mixed feed.
Here is a step-by-step guide to assembling and installing your Venturi fertilizer injector kit into an irrigation line.
Step 1 Assemble the Venturi Suction Kit
First, connect the accessory parts directly to the main Venturi injector body
-
Attach the Flow Valve Push one end of the clear vinyl suction tubing onto the barbed fitting of the black valve with the red handle (or secure it via the threaded compression collar if your model uses screw caps).
-
Connect to Injector Attach the short tube coming off the other side of the red valve directly onto the side suction port of the black Venturi body (the T-junction stem).
-
Attach the Suction Filter Push the weighted mesh filter onto the far end of the clear suction tube. This filter will sit at the bottom of your fertilizer bucket to screen out debris.
Step 2 Choose Your Setup
Best for simple gardens where you always want fertigation running whenever the water is turned on.
-
Thread the main inlet end of the Venturi tube directly onto your supply line (or an automatic timer/faucet adapter, supplied). Ensure the directional arrow printed on the Venturi body points toward your plants (in the direction of water flow).
-
Thread the outlet end of the Venturi unit to your downstream drip line or manifold, supplied
Step 3 Connect to the Fertilizer Supply
-
Place a bucket or reservoir containing your water-soluble fertilizer mixture near the injector.
-
Submerge the weighted mesh filter end of the clear hose completely into the fertilizer liquid. Ensure it rests at the bottom without curling out of the water.
-
Adjust Fertilizer Draw Turn the red knob on the suction valve to open or throttle the rate at which fertilizer is drawn up the clear tubing. You will see the liquid rising through the tube once suction begins.

Let customers speak for us
These items were just what I needed to repair my plant irrigation system. They were delivered in good time on the day specified.
Dealt with Steve (and Louis) who were great. I was not sure how easy the system would be to install and how good it would be. First class on both accounts. It all fits together easily (but remember to heat the pipe ends in hot water for 25s before connecting).
I purchased these items on-line after trying three local garden centres, none of which carried any stock. I ordered the items one evening and received them within a day and a half. I felt the service and delivery were quick and efficient.
So much easier than the push fit equivalent which are almost impossible to fit and definitely impossible to demount. These are easy to connect, can be demounted if necessary and don't leak.
Does exactly what it says on the packet, adjustable from a drip to a small spray.
I am extremely pleased with my purchase. I installed everything at the weekend and it is all working perfectly and doing the job. I was talked through what was needed for my garden and the order was put together immediately and I received it within a couple of days. Excellent, thankyou
Very impressive. Water a wide span. Would definitely recommend
Not just this product - but the great customer service and friendly advice make this company the best choice for garden irrigation. Thanks, Steve.
This adapter is so much better than the old make. Hole and push the adapters into. The don't leak, will be picking upma few more as I start to replace my other fittings.
These connectors are of very good quality strong and easy to fix on the tubes. No more dangerous and awkward boiling water. They are certainly 'anti-leak. Wish I had found these earlier. Strongly recommend.
Good arrangement, plenty of slot pipework and feeder pipework. Easy to work out how it worked, although laying out the pipe gave me kinks. Now kniw how to do it to avoid them
The advice I got from Steve at Gardenwatering.com, was first-class and so helpful. Introducing me to the range of anti-leak connectors. A great product.
My gardener is now using them for other clients. Would certainly highly recommend
These connectors are absolutely marvellous. I've spent hours with the old type. Soaking the tube in hot water, which can be very awkward and dangerous, pushing on the tube only to find it splits.
With these anti-leak connectors, they are so easy to fit and are strongly made. The description is correct- they don't leak. I would certainly recommend them and will use no other on my irrigation system
