Exterior Hot water unit not filling

[crackacoldie]

Hi All,

Today we had very low water pressure on mains, I cleaned out the one way valve and that problem is now fixed. Unfortunately we cannot get any hot water, it appears as if the hot water service is not filling from either mains or tank. Does anyone have any idea on what the cause may be?

Cheers

Cracka

Not sure @crackacoldie. Have you turned on your 12v pump, opened hot water tap and seen if it fills that way? Edit - just re read your post. It seems you have tried this.

Lift the pressure relief valve to let the air out, basically the same as twscoot suggested, but a different method

Was an air lock, was unable to release through the pressure valve. Removed the inlet pipe and all is now good
