Can I use Porta-Pak or Bio-Pak in my yacht’s holding tank?

March 15, 2021

If you own a sailboat, yacht, or other vessel that has a toilet and you want to prevent or eliminate unpleasant odors, Walex has the solution.

You can use either Bio-Pak or Porta-Pak in your boat’s holding tank. Walex’s RV holding tank deodorizers are also designed for marine use.

Walex’s R&D department recently tested Porta-Pak and Bio-Pak in saltwater since some yacht owners use seawater to flush their toilets. We found only a slight slowdown in enzyme digestion in Bio-Pak, and it still dissolved the toilet paper.

Usage of drop-in deodorizers is the same in RV toilets and yacht toilets. After dumping, start with one packet of product and 1.25 gallons of water for every 10 gallons of holding tank. Five gallons of water will let the waste and paper fall below the waterline, allowing the product to go to work controlling odors.

Happy Adventuring!
