How To Keep Your RV Holding Tanks Free Of Sewer Rats and Flies

Sewer rats living in your RV’s gray water tank? Sewer flies breeding in your black water tank ? It may sound like an urban legend or the stuff of nightmares, but unfortunately, these things can happen if you’re not careful.

 

As the name implies, sewer flies (or drain flies) live in the sewer system, so they can have a clear path to your RV if you neglect to keep your gray water tank closed while in an RV park.

 

In this video with RV Travel’s Chuck Woodbury, you’ll hear about a couple that heard thumping noises in the middle of the night after making this common RV waste management mistake. It turned out that the couple wasn’t alone in their RV — a sewer rat was living with them! You’ll also watch Chuck tell the story of a woman who watched in horror as sewer flies emerged from her toilet after making the same mistake.

RV Waste Management 101: 3 Reasons You Should Keep Your Grey Water Tank Closed

Whether you’re new to RV living or an old pro, you know that after connecting your sewer hose, you keep the black water tank closed, while you’re at an RV park. But many RVers are in the habit of leaving their grey water holding tank open anytime they’re hooked up at a campground. While this may prevent dirty water from backing up into your shower and sinks, it can cause some other truly unpleasant issues.

 

Here’s why:

  • If your grey water tank is allowed to fully empty, scum will build up in both the tank and the inside of the hose — in addition to being unsanitary, this can cause a really nasty smell!
  • If you let your grey water tank fill to ⅔ full before emptying it, a vortex is created which helps to remove the scum and eliminate most buildup.
