Venturi Fertilizer Injector Dispenser Garden Irrigation Device Kit, G3/4 Fertilizer Injector Switch Water Tube Kit

Purchased this for my water system in a Polly tunnel and I should have read the reviews as it’s useless, unless you have the water pressure of a fire hydrant or your hose is 2 feet long and has nothing on the end it won’t work. Not fit for purpose so returning it for a refund, this should not be for sale as it doesn’t work, has the seller even tried one?

It works on a short hose, this isn’t good for a sprinkler system or a long hose. There must be a pressure difference between the incoming water and the outgoing water for this to work.

Saw this Demonstrated by a YouTube channel it in principle is an Amazing idea however I just couldn't get to work, even with the help and support of the YouTube channel creator

No good what So ever absolute rubbish

Delivery was ok as expected. But no fertiliser injector in the package.

It only works with very specific water pressure. An open hose end and hose no longer then 10ft

Can't use it for drip systems, doesn't suck. Very hard to use as you need PRECISE pressure.

I'm using it with a 6 cylinder diesel pump irrigating 38 acres of onions on a drip system running about 500 gallons a minute through my main line. In order for a ventry to work the pressure difference in between the inlet and outlet of the Venturi needs to be 20 to 25% and your flow rate should not be restricted. However your main line needs a restriction. The 3/4 will drain a 500 gallon fertilizer tank in less than an hour running wide open. If you have issues with it you're installing it wrong and if you think you're not going to need more parts you probably shouldn't buy it.

Bought this item unsure if it was what I needed but it was exactly what I wanted. Quick delivery good price

Note! 1st injector did not work as it should. I did write back to Seller indicating a problem existed. The seller immediately shipped out a new injector, and yes, it's now installed and working as it should.THANKS : Seller ---------THanks Amazon , your services well done, You listen.

This is a worthless piece of junk. It doesn’t come with any instructions, so you just have to figure it out on your own. It has two male ends, so hooking it up in an existing irrigation setup requires an adapter. And then... after all that, it doesn’t work AT ALL! I looked up troubleshooting videos and similar devices, and my conclusion is that it MIGHT work if you have a fully open hose end, but it most certainly does not work for a drip irrigation system, which is what I bought it for. Worthless.
