Frequently Asked Questions

How long should RV sewer hose be?

Your RV sewer hose (used for black waste water) should be long enough to provide enough distance to safely discharge waste from your motorhome or caravan into a dump station sewerage tank. RV Super Centre has hoses in a range of lengths including the convoluted waste water hose which is sold per metre.

Are RV septic hoses Universal?

In New Zealand, the most common waste water systems are 25mm and 28mm. For those who need a bit of extra space, there are also 32mm systems. If you’re not sure which waste water hose is right for you, contact your local RV Super Centre, we’re happy to help!

How do you connect waste water to a caravan?

Connecting and emptying your waste water is very easy once you know the basics. RV Super Centre has some helpful videos on how to empty your toilet cassette and how to dispose of your waste water.
