tu_pence said:I have a linea 24 boiler. Pressure drops once the heating is off. The safety valve has been replaced and no leaks can be found.
tu_pence said:A pro replaced the valve. should i check the outside copper pipe to see if it is still leaking water?
Before my boiler problems the pressure gauge would only sit as 1.5 pressure. Is that normal?
tu_pence said:if i leave valve open it lets the air pressure that i pump in out.
also does anyone have any ideas why the water pressure keeps dropping if theres no leaks anywere and water is not being blown off by safety valve?
This set my alarm bells ringingtu_pence said:FINALLY, got someone out to check for leaks. None found. he put a bung on the outside copper pipe.
Pressure vessel definitely gonehe told me to keep an eye on the pressure. (he had left the boiler at 1.5 pressure) within 30 mins pressure was up to 3 bar
This turned my alarm bells off or at least quietened them down. Not the way I would recommend doing it but it at least indicated that this was only while things were being monitored and a reasonably safe procedure was being followed(he told me if this happend to turn heating off),
In a later post I sawI turned the boiler off and then water started coming out of a copper pipe in the boiler. It stopped once pressure was at 1.5 bar.
You already said the leak is coming out of a pipe in your boilerdoes anyone have any ideas why the water pressure keeps dropping if theres no leaks anywere and water is not being blown off by safety valve?
Ok heres some of what you missed when you nicked off from school all them years ago A liquid cannot be compressed. Water does expand and contract between 4ºC and freezing as I recall it expands about another tenth of its original volume.to my mind it should only show water pressure not air pressure.
and pumped up the pressure vessel. It was nearly full of water. If you didnt leave some way for the water to get out then all you did was increase the volume of air by a small amount.we88ie said:I'd let all pressure off completely so there no pressure on the gauge, leave the SRV open for another 30 seconds so air can be heard gurgling into the boiler.
Explain this more if you can. I'll try my take on what you said here.if i leave valve open it lets the air pressure that i pump in out.
