Discuss Why does the valve have two pressure relief nipples? in the USA area at PlumbersForums.net
I don't recognise that particular model, but it's not unusual for pressure-relief systems to have two stages. The first lower pressure one reseals after a low risk event. The second, higher pressure one is a 'burst-disc' that won't close after it's operated. This is just a guess, however, the OP will need to look at the manufacturer's specs to get a reliable answer.Anyone?
It’s the infeed from the local supply.What is the flexible hose connected to the other end?
Thanks, I can’t find a manufacturer on the valve. Having turned the mains water pressure down, it’s stopped dripping from the right and the left outlet only drips when it’s over temperature or we‘re drawing hot water from it for a prolonged period (i.e. running the shower).I don't recognise that particular model, but it's not unusual for pressure-relief systems to have two stages.

Hmm. Check the instructions for the water heater, the valve probably came with it. To be honest, the valve shouldn't be dripping under normal usage so it needs investigating. Contact the water heater manufacturer for a list of local approved repairers.Thanks, I can’t find a manufacturer on the valve.
