Q&A Home

Garland from Anniston, Alabama writes,

Is it safe to treat toilets in an RV?

This past summer I had the problem of drain flies coming from RV holding tank of black water. Are these products safe for this type of plumbing?


Yes, Invade Bio Drain can be used inside toilets in an RV.

A better option may be to use the Invade Hotspot because it foams and will coat the drain better.
