Hi guys I was bolting down my downstairs toilet into the concrete floor. I drilled down 10cm into the concrete floor to fit the plugs and at about 8cm the drill came out the other side - i was not expecting this. Will I have I drilled through a DPM? Do I need to seal the hole? What should I...

No thermostatic, just lockshield at each end of the rad, I know one works because I refilled the rad through it. But interestingly, the one on the T side, when I had the rad off the wall, did not leak any water if it was 'open' or closed. Does this mean the lock shield has failed shut? Would...
