Downstairs loo, was very slow to flush, it was taking ages for the bowl to empty.
Its not the loo itself its the soil pipe to the main sewer.
How do I know this? The output of the bowl is connected to a flexi pipe that then goes to soil pipe. If I unplug the connection to the soil pipe and shine a torch down it, it goes down about 2-3 feet and there is standing water in it, which shouldn't be there.
This morning I shoved a litre of 95% concentrate of sulphuric acid down it, left it 3 hours reconnected the loo and flushed it. The flush was better but still not as it should be. So tomorrow morning I plan to shove another litre of sulphuric acid down it and leave it all day.
Don't know what else to do tbh, rodding it from the sewer end is likely to be a costly job, as the manhole, as far as I can make is buried under the patio....if there is one there, peeking over the neighbours fence seem to suggest this, tho the neighbour on one side has got an extension over his......
