Hello I need to connect a garden hose (plastic) to the input of a tap which is a 15mm compression fitting. Photos attached. The hose outer diameter is about 16mm so just won't squeeze in properly. I'm DIYing a garden fountain. I think I need a separate adapter but I don't know what will work. Cheers for any suggestions Mike
Short bit of copper into the fitting, heat up the hose and expand it over the copper end and a jubilee clip to hold it in place
