We've had similar problems here, as it used to be a dairy farm (many moons ago) & the water pressure is very high - the only fittings that we've managed to keep on are the (expensive
) Hozelock ones. As Robert said a good quality hose will help too, as the cheaper ones give-out around the fittings & blow - so out comes the saw again
- our 50 metre hoses had ended-up as 10 metre ones - & it's such a flaff, coz they always went when it was raining
