I got second opinion from other gas engineer before i book an appointment with leak detection company. the gas engineer says that the pressure gauge is in wrong place hence pressure goes to 1 bar from 0 bar low pressure with out topping up. the gauge is now connected between temp and pressure...

looking for someone 'no fix, no fee' job. let me know. RG6 area.

thank you. what kind of expert do i need to get to look into? is this normal gas engineer? or unvented engineer? Because i have kept posting my update that i got gas engineer to look into. He checked expansion vessel and put sealant in the system .but still the issue that pressure goes to zero...

is this an issue? do i need to get leak detection to look into ? ======== When the unvented hot water mega system is ideal/cold, the pressure goes to zero on gauge at the unvented system. but when i start the central heating with out topping up, the pressure automatically goes to 1 bar. is this...

When the unvented hot water mega system is ideal/cold, the pressure goes to zero on gauge at the unvented system. but when i start the central heating with out topping up, the pressure automatically goes to 1 bar. is this normal or any issues? i wonder how pressure goes to 1 bar with out...

So water could be escaping somewhere under the floor (tiles) because I have been having this low pressure problem for one year especially during winter: Should I then get leak detect engineer to detect leak under floor ? Do they trace the leak with central heating pipe? Can you advise

Thank you

Thank you

Another clear picture attached

Thank you Everyone. I have attached my picture of my cylinder temp&pressure relief value connected to tundish. Sir, Please can you have a look at the picture and let me know if this still not correct I will get a gas engineer to look at it.

What is the issue please ? Is the water leaking somewhere? Or is it ab issue with pressure expansion vessel?

Update : So, I got gas engineer to check the pressure of the expansion vessel. He checked and confirmed pressure of the expansion vessel is fine and put fernox leak sealer. But still today the pressure went down close to zero when system was cold and no usage around 3pm however when i start...

Is these two not same ?Expansion vessel and pressure expansion vessels

thank you. appreciate it.

I want to update back to the forum 1. when system is not running, the pressure gauge shows ZERO bar (whole day central heating was on at 19'c), when i started the central heating to 21'c today the pressure is automatically increased to 1 bar with in 5 mins. does this indicate a leak? if water...
