Switching to a low-flow toilet is a must as part of efforts
to conserve water. Some cities and towns even offer rebates
to those switching from an older, high-gallons per flush toilet
to a new one. These programs offer rebates to current residents
who do so. Check below to see if the place where you live
(US and Canada only) currently offers a rebate program. Please
check with your water company before making the change – some,
though few, companies require pre-approval for participation
in these programs.
