Hi,
I have looked on this site for the answer to this question but couldn't find it.
My hot water pressure feels like its getting low.
System is 7 years old and has never been touched apart from the normal yearly gas cert.
All system is outside.
I wondered if it was to do with internal air bubble. I understand to recharge air bubble is to shut off cold water combination valve and then open hot water tap in doors. After that then open PRV on tank.
What I'm not sure of is when I shut of cold water combination valve and open hot water tap in doors there is no hot water flowing. I thought the idea was to open hot water tap to empty tank, but nothing.
Anyway I went to PRV and opened that and it literally dripped to the tundish with gargling noises.
Any ideas to help me understand / steer me to the correct path would be highly appreciated.
Thank you
