I have a traditional i.e not a combi central heating system, with a hot water storage tank. A week ago, there began a series of "rumblings" from some of the pipework - a friend subsequently identified that the pump was broken.
I can get a colleague to fix it, but not until Wednesday - are there any short-term problems with using my system until then? Hot water and heating are both working fine, but the "rumblings" from certain pipes have increased fairly dramatically, and are constant, even when the system is off.
Any advice greatly appreciated.
