Myson Apollo wall mounted gravity fed CH system - Loud banging
Sorry to keep persisting with my noisy CH System, but I have just had a Eureka moment. After i had finished descaling the whole system I turned the central heating on to start bleeding the rads etc. After about 10 minutes the banging started as usual, but I also noted that seconds before the banging started I heard a click and the pump stopped. The question I have is - is this a faulty pump overun switch or what. If so how do I change it? If I keep switching the boiler setting between high and low the pump fires up again and the system then runs ok
