Hello,
We have an issue with our downstairs radiators not warming up. Upstairs working fine. Boiler has been serviced and all fine. Boiler man said we needed a power flush. System has been power flushed. Radiators get warm with the power flush machine active but not with the boiler. Tried turning all upstairs radiators off but still no heat reaching downstairs.
The Powerflush guy suggested there is a number of things this could be, the first thing to check being the three way diverter valve, but having read online about how this works it doesn't seem to differentiate between upstairs and downstairs and is clearly supplying part of the heating system?
Pump is working. Rads are bled. Open vented system (I think that's the name? We have a tank in the loft that feeds the system and a hot water cylinder)
10mm pipes which isn't ideal, but they've worked fine up until now.
Am I missing something or is there suddenly a complete blockage between the last upstairs radiator in the loop and the first downstairs one?
Thanks in advance for any help
