In residential settings, dual-flush toilets that do not meet current water efficiency standards may not be permitted, as well as older gravity-flush toilets that use excessive water per flush. Additionally, any flushing device that does not comply with local Plumbing codes or environmental regulations, such as those that lack a proper backflow prevention mechanism, is typically not allowed. It's essential to check local building codes for specific restrictions on flushing devices.
