Mains flushing radiators, combi boiler
Can i check if the procedure i am following is correct?
Close all TRV's on all the radiators apart from one radiator, starting upstairs..
Open the boiler filling loop
Open drain point located in bathroom to flush through for 5 mins
Close the first radiator and then do the same to the next radiator and so forth
Is the above procedure correct?
Would you also recommend when doing the flush to close the lockshield valve before moving to the next radiator?
