AHI in AR Posted May 15, 2013 Report Share Posted May 15, 2013 I came across a toilet in a home today which would flush twice with one flip of the handle. The water would swirl and drain, looking normal, then refill again quickly and drain again. Two other toilets of similar design in the home didn't do this. Unfortunately, the sellers came home with a sick baby and I wasn't able to pull the cover off the tank and run it through a few cycles to try to figure out what was happening. It was a conventional toilet, not anything exotic. Anyone know what's going on? Quote Link to comment Share on other sites More sharing options...
Marc Posted May 15, 2013 Report Share Posted May 15, 2013 Partial clog in the drain, the float has lost some buoyancy or the water level in the tank was too low to do the job on the first flush. Marc Quote Link to comment Share on other sites More sharing options...
AHI in AR Posted May 16, 2013 Author Report Share Posted May 16, 2013 I dunno. By my admittedly unscientific approach of simply watching all three toilets flush I'd have to say that the amount of water that went out with the first flush matched that of the other 2 toilets in the home.

Stephen Lagueux Posted May 16, 2013 Report Share Posted May 16, 2013 perhaps the succion of the water going down from the first flush sucks the second fill down with it. Possibly caused by undersized drain and or bad ventilation....having one of those would come pretty handy sometimes. Quote Link to comment Share on other sites More sharing options...
kurt Posted May 16, 2013 Report Share Posted May 16, 2013 Kohler Wellington's did that a lot if someone reset the foam thingie on the flapper chain. Quote Link to comment Share on other sites More sharing options...
Les Posted May 16, 2013 Report Share Posted May 16, 2013 Kevin, are you saying the water left the bowl (completely) twice or are you saying the tank released water twice? Not an uncommon thing with mis-matched tank/stool. Quote Link to comment Share on other sites More sharing options...
AHI in AR Posted May 16, 2013 Author Report Share Posted May 16, 2013 Les-- The water swirled around and drained as is normal. But instead of simply filling back up it filled up quickly and then flushed again just as soon as it was through filling. The bowl then refilled as it should with no more flushing. All 3 toilets in the home were identical. This was the only one doing this so it wasn't a mismatched bowl/tank issue. Quote Link to comment Share on other sites More sharing options...
4000sposse Posted May 17, 2013 Report Share Posted May 17, 2013 Sounds like it is draining too slow once the water flushes out of the bowl (partial clog like Marc said), and the bowl is filling up fast enough for the siphon effect to continue and flush the bowl again.
