I recently had to replace a toilet supply line and I thought I'd try
out a Watts Floodsafe since it seemed like a good idea and it didn't
cost much more then a standard line. It seems to work fairly well, so
well in fact it shuts off the flow of water every time I flush the
toilet! The fill valve is a Fluidmaster 400A and the fill rate does
not seem out of the ordinary. I tried choking down on the supply valve
and the flow rate has to be ridiculously low in order for the
Floodsafe to allow water flow. Anyone have any experience with the
Floodsafe lines? Thanks.


Never used them on a toilet but they seem to work fine on sinks so long as
the aerator is installed. You might have a bad one. Try switching it out.
