Flushing holding tank

[BobHaze101]

Quick question: in my 2013 R29S can I add water to my holding tank through the "Waste" deck plate? I'm getting hauled out for the season next week and would like to fill it half-full then have it pumped out first, prior to winterizing.

I do this every time I pump out. No issues filling through deck plate.

I do it 2-3 times around September to clean out the holding tank. Most of our pump out stations have water and a hose next to them specifically for this purpose. Always fill through the deck plate.

Pro Tip: Never use that water hose near the pump out for filling your freshwater tank. 😀

I pump the tank out, then fill it with freshwater until it's full. Pump it out again... Our waste tank is 30 gallons.

Do you guys have a rule of thumb of how long you stand there filling the tank with water? I’m shooting to get it at least half full, but my gauge is broken so trying to do some guesstimates re hose fill speed, etc and love to hear how others do it.

Yes, rinsing the tank with fresh water before a winter’s nap is a good thing! You can buy a water flow meter for a garden hose on Amazon. I use the meter to help monitor our fresh water usage rate at each fill and to measure what I add to the holding tank when rinsing.
