Dramm 22625 Syphonject Siphon Mixer with External Check Valve

This is a great product. Not sure about the poor reviews, it doesn’t get much easier than attaching it to the spigot and turning the water on.. I run it in between 2 hoses, the 1st hose is 50ft, the 2nd is also 50ft. Makes small dose fertilizing a breeze. 7/28 Update. Have had the product for less than 2 months , unfortunately something internally has malfunctioned and the back flow is now filling my concentrate bucket. The product worked great up to this point. I’m going to reach out to the seller for a replacement. 7/28 Update- outstanding customer service , which is why I will continue to buy Dramm products. 1st issue I have had and they are great

6/18/2025 TL;DR update - I have used this item exactly twice over the course of two days. The first time went fantastically! That's what my original review was based on. Now it's been a few days and I needed to refertilize my garden as before, and just like everybody else it has broken and is spraying everywhere like a fountain against my foundation of my home. I CANNOT recommend this anymore. Zero restriction on the end, even when utilizing the provided nozzle it still will no longer siphon. I suppose it makes for a great water feature if you're looking for a fountain next to your home. ========== 6/16/2025 Original Review: For the uninitiated, do not install a shut off switch AFTER this Venturi. Basically if you have one of those "squeeze-to-spray" classic garden hose sprayers you WILL break this as soon as you stop the flow of water. The way that I hooked it up was to get those inline quick adapters. I made sure they were the kind that didn't automatically shut off when they come on clicked. Then I can just click it in-line at the hose bib and have it run fertilizer through my garden hose out to my oscillating fan sprinkler in my garden or to a sprinkler by my fruit trees. Works perfectly! Just toss the weighted metal end into a bucket and easy peasy away it goes with no leaks or explosions. The reason it comes with a non-stopping flow nozzle is to prevent you from stopping the flow. If you stop the flow after this nozzle you are basically making a plastic pipe bomb in the middle of your garden hose and it's completely your fault for breaking the check valve, or the fitting itself. Couldn't have been a better purchase and saved a bunch of money by not going with the brass version that was twice the price.

Works great and heck of a deal.

It took several tries to get this to work. Tried on both sides of the house, no luck. Then I tried it with a different nozzles and it wasn't until I took all of them off that it worked. I like not having to mix up different buckets, but after switching sides a couple times now notice the threads are stripped and it leaks.

It worked great for a first few times i used it, then the anti-back-flow valve quit siphoning, removed that valve, now it siphons with ease and fills up my bucket of concentration of fertilizer. Would have gave it 5 stars if that valve always worked after a few times of using it

I have purchased the brass version of this item in the past. They have always stopped siphoning within the year. So, I decided to try the cheaper plastic versiion. So far, so good. Works perfectly. I use one of those big plastic jugs that you get pretzels in at Sams or Costco. I drilled a hole in the lid for the siphone tube. I put 1/2 a big bag of Miracle grow in it and then everything gets fertized while I water. I noticed in the nurseries that continually fertilize with a low mixture and that is why their plants are humungous. This system works that way for me. Much easier than filling 2 gallon buckets with fertilizer and carrying all around the house. If you have many plants or a veggie garden, both in the ground or in pots, this is a great way to deliver the fertilizer.

Does not work. Minimal documentation states a flow of at least 35 psi required. I also purchased a rain bird pressure gauge which reads 75 psi on my faucet. One gallon of syphon/conentrate made 20 gallons. but when I make a gallon of concentrate to ph water to 5.8 to 6 per gallon. 4ml of PH down makes 5.8 to 6 ph gallon of water. So at a 20 to 1 ratio I put 80ml of PH down in a gallon for the syphonject to dispense a flow properly PH gallons. Did not work! Measured each 20 gallon and the syphonject only brought the PH down to 7.2 from 7.8. Now when the hose is not flow the syphonject reverses the flow and Fills Up the concentrate. Completely useless piece of plastic. Love Dramm's other products. Do Not Waste your time with this one.

With no instructions provided (found them later on the web), I wasn't sure I was using this correctly. I tried following all instructions, have sufficient water pressure, the right flow rate, correct hosing...but still the water leaks from the hole instead of siphoning correctly. Don't get me wrong, it is marginally usable because it does draw solution into the hose, but it leaks out more solution than I'd like. So I simply put my bucket of solution under the syphonject, so it leaks back into the bucket to be drawn up again. If I'd been able to find it in time to return it, I would have.

Tried it out once. Used it to fertigate Biofish (liquid organic) through drip lines. It seemed to work fine. I strained it first so it wouldn't clog the drip tape. Just like the product info says, there is a minimum flow rate necessary (about 5 gpm) for siphon to occur. It didn't work at first because I didn't have enough drip tape running. I had the equivalent of nearly 500' of drip tape with emitters spaced 4" apart to get it to operate successfully. I think this will be very convenient for feeding plants in the future.

Very happy with my new Dramm syphonjet,much easier to water in liquid supplements with a hose instead of the watering can backwards and forwards.

Really works well! Once you use a siphon mixer like this you will not want to go back to a mixer that is on the end of the hose.... I have a large yard, and I connect this between a 100 ft hose and the 50 ft hose I water with.... Put 20 scoops of miracle grow in a bucket with 6 litres of water, and have enough solution to water and fertilize my large garden (10x30) and several planters. I used to have a brass one, but brass oxidizes... I don't think I will have any problems with this plastic one for years!

Too difficult to get it working , not worth the plastic it is made from
