How long will my Walex deodoriser last?

We often get questions from RV owners about how often to use Porta-Pak or Bio-Pak, and how long one bag of the product will last. The short answer is this: two people living in an RV or caravan in a moderate climate will need to drop in one packet every five to seven days. Each Porta-Pak and Bio-Pak bag contains 10-packets, so the length of time one bag lasts depends on the number of people using the RV’s facilities.

We recommend adding a new packet of deodorizer right after you empty your tank. Always wait to empty your holding tank until your sensors show that it’s 2/3 full because gravity helps move all the solids out when you open the valve. Plus, if you’re using a product like Bio-Pak, waiting long enough to empty will give the enzymes more time to liquefy the waste and paper.

After emptying the tank and adding your Walex drop-in, make sure to add enough water to disperse the ingredients throughout the holding tank. The odor is less prevalent when the waste and paper sinks below the waterline. Otherwise, you may have a pyramid of waste and paper above the water line that causes malodor. We recommend starting with 5 litres of water for every 40 litre of holding tank. With adequate water added, one packet of deodorizer will control odor and treat waste up to a 150 litres.

One more thing to keep in mind: controlling holding tank odors depends heavily on watching your sensors, and if you start getting false sensor readings, you won’t know when to empty and refill your tank. When this happens, you’ll want to drop in one packet of Commando. This super-concentrated enzyme-based formula liquefies residual waste and paper build up within the tank, lubricates your valves, and cleans your sensors. Give Commando a minimum of 12-24 hours to do its job and your tank will be good as new.
