Bunker
This morning I started my first power flush. 13 rad house, some downstairs rads have huge cold spots in the middle - in fact easier to say they had small warm spots on the ends. The 2 main culprits are an 1800x500 double rad and a 2250x500 double.
Its a Sentinel Flush4 machine and am using Sentinel X800. Followed the MI but despite LOADS of gunk coming out, the cold spot on the bigger rad hardly budged. I was there for 3 1/2 hours pretty much just on those 2 rads (including initial set up, wash out etc). I tried slapping the rads with a length of wood and palm banging them. Im going back on wednesday so will take a rubber mallet too. Ive hired the machine for a week and got some more work done this alvo so I havnt lost out much. I threw in another tub of de-sludger I had in the van and restored the system, hoping it will work its magic over the next 48hrs.
Anyone any advice beyond this?
Many thanks
