Yet another toilet thread, I'm afraid ...
Out downstairs loo was originally an outside lavatory but it's been turned round at some stage and the toilet now backs onto the outside wall.
The waste goes down into the concrete floor and under the wall and, presumably, somehow makes its way to the stack about 3m away. There is no access to it at all, so I hope I never have a serious problem!
For two or three days it has been emptying much more than usual. The water level doesn't quite reach the inside corner of the bend, but it's not far off.
We're having a slight thaw today and I noticed about half an hour ago that it seemed to flush normally, with the water level reinstated to the usual level. From this I presume that the freezing weather has some bearing on this but I can't puzzle out how or why.
What does the panel think?
