Megaflow Unvented Mains water heater - pressure dropped

[canarygirl228]

Hi

I have a Megaflow Unvented Mains water heater. The pressure gauge black needle has dropped to 0.8. The red needle is 2.8.

I have been advised the black needle should be at 1.5. Can anyone advise me how to increase the pressure?

Thanks so much.

Search the forum for filling loop and all will be well.

Has pressure dropped to the cold outlets within the house? I take it you mean the optional pressure gauge that goes on the cold water inlet valve? This you cannot re-pressure as it is what the mains is coming in at.
