One of the pressure release valves underneath one of the two Voker
Mynute 28 - 96 SE boilers in my garage has started leaking water on an off.
It is an intermittent drip. Sometimes no leak for a couple of days an then about half a liter in one day.
The pressure in the boiler when cold is about 1 bar, as it has alway been. Often, I top up a bit after a leak.
The problem happens with and without topping up the circuit wit water.
Nothing different from the past in the radiators switched on in th house.
Although all four valves, two in each boiler, show old stains as i there have been leaks before, this amount of water does not soun normal to me. Am I correct?
If it is indeed not normal I will call a Vokera engineer to look int it because replacing the valves seems to me a difficult and specialise job.
Thanks,
Antoni
