Thanks for tips. I've opted to purchase a Sentinel Rapid Dose valve for the filling loop (or maybe get the one you use in the rad) then buy the rapid dose X100 in the can and inject it that way. I can't seem to find a drainage point for my sealed system. There are none on the radiators...

Mission failed. Got the empty rad on, but the Sentinel kept running out of the radiator despite taking the blanking nut out and opening the bleed valve on the opposite end. I tried to use a funnel with length of thin plastic tubing pushed down inside the radiator. I do have a filling loop...

Nice one... cheers. Just that you read mixing inhibitors from different manufacturers is a no no, but nowhere does it states what the consequences are of such an action. So if I understand correctly, if I take the entire nut off then the air will simply be displaced via the same hole as...

Yep, new radiators.... well 4 years old. The bleed pin is set in what looks like a silver nut, and there is one at the top on the other side (but with no bleed pin). Are you saying take this entire nut out or just the bleed pin and inject the sentinel? If I take just the bleed pin out...

Hi, I took two radiators off for decorating, I have put one back and filled due to cold weather. Yet to put the other one back on. I have decided it would be good to add inhibitor due to having diluted the system, and by replacing the second radiator I will be diluting it even more. Only...

Did you get any problems with this. I recently had my garage roof stripped, new underfelt (Tyvek Supro) laid. I seem to recall that they laid concrete fibre boards along each verge and the felt overlapped on top of them, not underneath. These are now concreted up to form a wet verge...

cheers for your replies.... On closer inspection, the transformer (which is connected to the light fitting itself) has the two wires coming from it into the connector block, and the earth seems to come from behind the transformer into the connector block, more than likely directly connected...

Hi, I have a lighting circuit with no earth. I have purchased a wall light from BHS (Amelie 3 light). The back of the light shows a square within a square on the plastic transformer, but still has an earth wire coming out of it and into an external connection block and the instructions...
