Is it safe for septic tanks?

I called Walex but did not wait for a call back. I emailed them right away too. This is their answer about Porta-Pak:Porta-Pak will not harm your septic system when being used by a single RV. It would take 100's of RV's dumping the product daily into the septic system before the septic culture would even notice the product is in it. The product gets so diluted in the holding tank there is nothing left of the product when dumped into a septic system. I do have a question/suggestion for you. If your RV was used I always recommend you filling the black holding tank as high as you can with fresh water and adding 1 Porta-Pak in the tank for 24 hours and let it clean the tank thoroughly before you use. This will give you the reassurance that the tank is free of any old ill effects and leave you free to enjoy your camping. This is also a good practice to do before winterizing, so that you prevent any foul odors sneaking up on you when you get ready to start camping again. Congrats on the new trailer. Enjoy your travels and be rest assured that you won't have to worry about the holding tank. If you have any other questions please don't hesitate to call or write.Kindest regards, Todd ViceRV and Marine Sales ManagerWalex Products Company, Inc.PO Box 3785Wilmington, NC 28406(O)910-371-2242(F)910-371-2094

Has anyone used it at mardi gras parade?

HOW would you use a toilet deodorizer at Mardi Gras?

A toilet bowl cleaner dropped as packet into toilet bowl-fizzes pink, cleans, and disinfects...it stops fizzing,toilet bowl clean. Flush. Whose is it?

I believe but not positive that that is a mr clean or magic scrubbing bubble product not good for your rv or trailer set however ,it has chemicals that counter act the septic pals shown in this post .. it won’t ruin it right away but over time it will hurt the sensors and the clean out mechanisms
