The United states uses a 3/4" Garden Hose Thread standard for all garden hoses. The Edyn Water Valve is designed for these types of systems. In the UK and select countries, different-sized threads are used. While these systems may have the same diameter, they have different threading patterns and are incompatible. Please do not try to connect your Edyn Water Valve directly to a British Standard Pipe Thread hose as it can damage the fittings.
Luckily, it is easy to make an appropriate system by purchasing a garden hose with British (or other) style fittings, cutting in two, and splicing in US fittings.
Please purchase a length of garden hose with your native country's fittings on it from a local hardware store. Use a knife or scissor to cut the hose in half. Then purchase and use this kit to add US style fittings to the cut ends of the hose: http://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR0.TRC0.H0.XOrbit-Male-Female-Thread-Brass-3-4-Water-Hose-Repair-Garden-Hoses-Mender.TRS0&_nkw=Orbit-Male-Female-Thread-Brass-3-4-Water-Hose-Repair-Garden-Hoses-Mender&_sacat=0
If done correctly, you will end up with two lengths of hose with the following fittings on them:
Female British Thread:Male US Thread
Female US Thread: Male British Thread
You should now be able to connect your Edyn device between the two lengths of hose.
