Take the tour ×  I'm considering purchasing dual-flush
converters for our toilets and was curious if anyone had
thoughts on them. Specifically, I'd like to know:    • Are there
any major disadvantages to using them?   • How difficult are
they to install?   • Are there any specific considerations to
keep in mind for houses using septic systems?   share|improve
this question Don't know much about converters, but I will say I
love my dual-flush toilet. It saves a lot of water compared to
the old toilet I used to have, but sometimes I have to explain
to people which button to push. I'm planning on putting a 1 and
2 sticker on the buttons, as the etched I and II are not really
visible (I think that might make it more self explanitory). –

years or so now. There are reports of not-super-impressive
results with converting very old toilets, but the concept is
well proven. –  MGOwen Oct 12 '10
