Hi, can anyone help me, i have a combi boiler and when i got up this morning i had no water up stairs (hot or cold) and only mains water down stairs. all pipes are inside the house and i dont think they have frozen. one thing i did try was to hold my finger over the cold tap down stairs and open the hot tap to force water up the hot pipes, this worked and we had water coming out of the hot and cold up stairs, so i dont think any of the pipes are frozen. heating is working fine.
