We had two new matching toilets fitted on first and ground floors in 2015. Recently the ground floor one has been acting strangely.
Randomly, but on average at ten-day intervals, the bowl has been found, hours after a normal flush, with the water level so low it barely covers the outlet rim, but never uncovers it completely. It would if there was a leak but it never has been uncovered, neither is there any foul smell a leak would cause. Flushing the bowl restores normal level, which remains normal pro tem.
The only cause I can think of is a temporary vacuum caused by a sudden rush of fluid past from my outlet to the common sewer from the two houses (of three) above mine, say if two baths were emptied at the same time. . This would cause water in the bowl to be sucked partially out. Can anyone suggest another cause?
