On a related note our plumber came round earlier to fit new waste and taps to the bathroom handbasin. I asked him about changing the old fashioned toilet for a more modern one. Not a straightforward job as the old loo has a side entry at the rear. While he was checking around the individual fitting he noticed that he could see daylight around the cistern overflow pipe where it goes through the wall 😮. He ssid it's possible that the original fitter had just slapped a bit of mortar around the pipe and this had crumbled away over the years. That certainly wasn't helping keeping the bathroom warm.
