I had to get my RidX out and reread the reasons why I use it at home. We sometimes use bleach in the wash and it will kill of the bacteria that the septic tank needs to work best. Could see no reason you would need to use this in the MH as I would think you would be emptying your black tank more than once every 3 months or more. I'm still somewhat new to this, but did live in a travel trailer for over a year while building our house and made the mistake of leaving the black valve open while it drained to our septic tank. WON"T DO THAT AGAIN. Still learning from many great ideas, thanks all.
