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.

Excellent quality like I expect from DRAMM.

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 works if you fight to get it on the water spicket.. threads not cut well in plastic. I had a brass one before this and loved it. I will keep it. I would buy brass if I need another one.

Exelente

I buy a ton of stuff on amazon and don't ever write reviews, but there were so many negative reviews about this item that after using it successfully I had to write one of my own. I took this item out of the package, set it up as directed using THE SPRAY NOZZLE THAT WAS INCLUDED WITH IT and used it to spray my entire lawn with a 5 gallon bucket of compost tea. It worked and it worked well. I can't understand why there are so many negative reviews about this product. Obviously, it will not work if the spray is restricted as the laws of physics require that the water be traveling through the hose at a sufficient velocity. If you use it as it is intended, it works flawlessly. I can't see using a product in a manner that is explicitly indicated in the instructions as NOT WORKING and then complaining that the product doesn't work. This product works just fine if you follow the instructions and is a good value.

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.

Parfait fait la job

Don’t buy this it has American thread and needs 35psi about 5gallons per minute to work. US has higher water pressure than UK. Unless you have a pressurised pump it won’t work.

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.

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.
