The BillyDump is a patented, telescoping RV drain system with a completely smooth interior bore. Unlike other drain systems that use a corrugated hose, the BillyDump uses only a short length of heavy-duty flexible hose to connect to the RV drain and another to direct the waste into the in-ground drain. The main tubes of the BillyDump have a smooth interior with no edges or corrugations to catch and hold waste. A vapor-seal prevents escape of sewer gas.
Regular Standard model shown in the collapsed position. Unit is just 66" in length fully collapsed yet quickly extends up to a full 10 feet! (donut not included with unit)
The BillyDump works with all RVs. It uses an industry standard bay adaptor to connect directly to the holding-tank drain fitting with just a slight twist. Standard models include a short length of heavy-duty hose with the bay adaptor already installed.
Basement model BillyDumps come with a "u-cut to length" upper hose to fit RVs with the drain connection located in a compartment.
