Dump Buddy RV hose fastening device — Red, secures 90° sewer elbow with patented clamp and tightening knob

Dump Buddy is a compact, patented RV hose fastening device that locks your sewer hose connector to a 90° elbow to help prevent accidental spills while dumping.

Emptying your RV holding tanks is a routine part of life on the road, but a dislodged hose or loose fitting can turn that chore into a mess. Dump Buddy is engineered to give recreational vehicle owners a quick, reliable way to secure the waste hose connection to standard 90-degree elbows and sewer pipe outlets. Lightweight and simple to operate, it provides extra mechanical retention so you can focus on completing the task with fewer worries about leaks or separation.

How does Dump Buddy keep the sewer connection from coming loose?

The device uses a two-part clamping geometry and a top-arm latch to hold the hose connector firmly against a 90° elbow. A tightening knob draws the clamp snug around the elbow's base while the upper arm captures the hose end, resisting accidental pull-out during dumping.

• Patented mechanical design for positive hold
• Tightening knob secures the clamp to the pipe (avoid over-tightening)
• Top arm swings into place to lock the hose connection
• Tested to withstand over 10 lbs of holding force

Which pipe sizes and materials does it fit?

Dump Buddy is sized for common RV sewer elbows and discharge pipes with outside diameters from about 3.9" to 5.75". It’s made from durable HDPE and ABS plastics that resist weathering and are easy to wash after use.

• Compatible with standard 90° RV sewer elbows and outlets
• Designed for OD range: approximately 3.9"–5.75"

What comes in the box and how simple is it to use?

Each Dump Buddy ships with the clamping device, a mesh drying bag, a canvas carry case for storage, and a clear instruction manual. Using the unit takes only a few steps: fit the clamp to the elbow, tighten the knob until snug, swing the top arm over the hose connector, and engage the latch.

Who is this for? Dump Buddy is intended for RV owners, motorhome drivers, and towable campers who want an extra layer of security during black- and gray-water disposal. It's particularly useful for solo campers, new RVers, or anyone who prefers a mechanical backup to prevent hose dislodgement. If you value a cleaner, less stressful dumping process and an accessory that stores easily in your rig, Dump Buddy is designed to be a practical addition to your camp setup.
