It was actually a hose belonging to @exxos , I was just theorisingPaulJ wrote: ↑Fri Nov 20, 2020 1:35 pm@rubber_jonnie , your lucky you were home and not sleeping. I worry about that here since water pressure is a lot higher. From the street water pressure is 120 PSI and there’s a regulator which has it turned down to 60 PSI. I do have a value on the washer so when not in use the water is off so if a hose does burst it has no water supply. One question though Jon.... What is GB doing using PSI? It’s hard to believe your not using something like KSML. (Kilograms per Square Milliliter) That hose must really have been bad to break at that low pressure. Matter of fact I can’t imagine using water at 15 PSI.
GB has long used PSI, we like our imperial measurements here I do mix my imperial and metric measurements up all the time, but you'd have to head over the English channel to start getting metric pressure measurements.
The govt standard for the mains water inlet to the house is .7 bar, 10.5 PSI and various sources state it's more like 1 bar, 15 PSI. The standard is filling a 4.5l, 1 gallon, container in 30 seconds.
Doing some digging, it's expected that the fittings in a UK home will allow up to a maximum of 5.5 bar, 82.5 PSI. The actual suggested domestic pressure is 3-4 bar, 45-60 PSI. So our internal pressures are about the same, but your 120 PSI mains inlet seems really high, it must leak incredibly if a pipe breaks!
