Smart Bidets That Have AVB Do I Still Need RPZ Backflow

mr_asstight on 18/01/2025 - 22:22

Does anyone have experience with smart electronic bidets that have AVBs built in and whether a RPZ Backflow valve is still needed if AVB is present?

Brands like Toto, National, etc seem to have AVBs and the salesman told me these don't need expensive RPZs.

  Thanks.
  It looks like AVB works as long as the downstream outlet is at least 6 inches or about 15.2cm higher than the source which is most setups

  It's not going to backflow from his butt into the bidet nozzle.
