as far as installation in concerned is an extra chain connected to the flush lever.
then you are protected against leaks:i think it’s worth it.
also i don’t think it will work at all unless that other chain is connected looks like.
let’s put it this way.it not only prevents refill if you lose water through the flush valve but suppose it empties onto the floor for some reason,it happens.
you do the math.
