My boiler keeps losing pressure on a daily basis. If I have a faulty pressure relief valve how long would it take to see discharge from outside pipe after repressurising boiler to say 2 bar. I can't see any water from discharge pipe from outside and if the pipes were leaking I would have seen it by now as I have been losing and topping up 2 bar of pressure daily. What is worrying me is that there is water going somewhere. I can hear water filling into bathroom radiator when I top up boiler pressure. Thanks
 
Boiler cold fill pressure is 1 bar. Put a container under the discharge or tie a balloon or thin rubber glove over it that can burst easily if you don't want to wait for it. Its most often a pressure vessel issue which requires a GSR to look at it. Likely to be within the boiler casing and therefore not a DIY job. Otherwise a leak elsewhere.

I have tied a bag around discharge pipe. Only about a thimble full of water in about 4 days. I have been topping up pressure daily. Can't see any leaks anywhere. Rad valves OK. Water would be coming through ceiling by now. No pipes going underground. Thanks
