New Boiler to replace a old Worcester 35CDi II

No aslong as it’s the outside tap leaking and nothing above

No, deffo just the tap leaking around a join by the looks of it

So I shut off the valves last night and took a photo along with one this morning when I opened them back up.

 

[ShaunCorbs]

Before you opened the valves was the pressure the same as the first photo ?

 

[j3oeff]

No, I took the picture of it under 1.5 bar then opened valves. Nothing dropped or went up. Just stayed at below 1.5 as second picture

 

[ShaunCorbs]

Hmm strange

 

[j3oeff]

So does that not point towards a boiler issue? Or should i of done it a different way? In stages what i did....

1) Turned Valves off at 11PM
2) Took photo of pressure gauge
3) Took photo of pressure gauge at 7AM
4) Opened Valves back up and needle stayed in the same position.

It points to no drop / leak

It points to no drop / leak

I thought....

If it’s where it was after you closed the valves the leak is on the system but if it drops it’s the boiler.

In my case, it's dropped from its original point last night so points to the boiler? Or am I reading it wrong?

 

[ShaunCorbs]

True but once the valves were open the pressure should rise I’m guessing the heating was still warm when you turned the valves off last night hence the 0.2 drop ?

Yes, the heating went off around 10.15ish.

Let's say I do it again to be 100% sure.

If heating goes off at say 9pm? Take a pic and close valves at gone 11pm? Then in the morning open valves and then take a pic or take pic then open valve?

 

[j3oeff]

Seems there was a slight drop last night.

 

[ShaunCorbs]

And boiler was cold before pic was taken ?

 

[j3oeff]

And boiler was cold before pic was taken ?

Stone Cold! Heating had been off for 2 hours 20 minutes before the pic at gone 11PM.

 

[ShaunCorbs]

Is the prv dripping outside ?
