I have just bought an old 3 storey house. It has toilets on the second and third floors. The toilet on the third floor works fine. The one on the second also flushes with no problem but the water level in the toilet bowl slowly drops over a couple of hours. Both toilets flush into the main vertical stack in the house. I have tried flushing the second floor toilet, letting it fill to its normal level and then flushing the third floor one to see if it is causing syphoning action but it has no effect on the second floor toilet level. Other than this there appear to be no other weird plumbing problems. The waste plumbing is ABS. Any ideas?
