You get what you pay for, this one is built to last. Review: 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. ## Features - Fertilizing has never been easier - Fertilize as you water - Lightweight corrosion-resistant plastic siphon mixer with an external check-valve - Average dilution ratio 20: 1 - Manufactured ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002KCY2WS | | ASIN | B002KCY2WS | | Brand Name | Dramm | | Color | Blue | | Customer Reviews | 4.2 4.2 out of 5 stars (1,645) | | Customer reviews | 4.2 4.2 out of 5 stars (1,645) | | Date First Available | 7 August 2012 | | Global Trade Identification Number | 00036434226259, 00036434226266 | | Is Discontinued By Manufacturer | No | | Item Dimensions L x W | 20.2L x 9.9W centimeters | | Item Length | 7.94 Inches | | Item Type Name | Dramm 22625 Syphonject Siphon Mixer with External Check Valve | | Item Weight | 3.2 Ounces | | Item model number | 22625 | | Manufacturer | Dramm | | Manufacturer | Dramm | | Material Type | Plastic | | Maximum Pressure | 35 Pound per Square Inch | | Nominal Wall Thickness | 0.125 inches | | Outside Diameter | 2 Inches | | Product Dimensions | 28.58 x 13.34 x 17.15 cm; 90.72 g | | UPC | 036434226259 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Dramm - **Colour:** Blue - **Item weight:** 3.2 Ounces - **Material:** Plastic - **Product dimensions:** 20.2L x 9.9W centimeters ## Images ![22625 Syphonject Siphon Mixer with External Check Valve - Image 1](https://m.media-amazon.com/images/I/71msGvzUwyL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by G***R on 5 August 2020* Better quality than many look alike products for a somewhat premium price.

The threads are not compatible with UK fittings.
