low hot water pressure from combination tank

[captain beep]

Hi, I couldn't find the answer to this in faqs so I hope someone can help.

I recently turned off the inflow to a friends combination tank and forgot to turn it back on.

The tank has been largely used without realising it wasn't refilling and, even though I've turned the cold water flow back on, the water flow from the hot taps is very low.

The make is Manco if it makes any difference.

Thanks in advance,
Captain Beep

air lock in pipework or scale blockage in internal pipework is likely cause

or blocked ballvalve

I heard the tank filling today so the ballvalve must be ok. Any tips on how to get the air out fellas ?
Thanks
