Worcester Ri back to front

[Bodd]

Worcester Ri Flow and return piped the wrong way round. Boiler is about 8 years old. Could this have done any long term damage?


There is nothing good about this system. Ive suggested a new combi but customer don't doesn't want to pay out.

Check to see if there are ripples in the heat exchanger , these would indicate overheating. If it's ok, repipe correctly.
