Product Description:

Upgrade Your Pop-Up Camper’s Grey Water Drain.

Stop messing with bulky, glued-together PVC reducers and leaky hardware store fittings. This single-piece adapter directly connects your pop-up camper’s 1.5-inch threaded grey water drain to any standard 3-inch RV sewer hose (Camco, Valterra, etc.) for a clean, direct connection at full-hookup campsites.

Choose Your Material:

We 3D print these in-house using industrial-grade, high-temperature polymers. Choose the plastic that fits your camping style:

• High-Value ABS: The perfect balance of extreme durability, high heat resistance (safe for boiling sink water), and excellent impact strength. Great for weekend warriors.
• Premium ASA: The ultimate permanent solution. ASA shares all the strength and heat resistance of ABS, but is highly UV-stable. It will not fade, chalk, or degrade under years of direct, punishing sunlight.

The Boondocker’s Blueprint (Complete Grey Water Containment):

Many National Parks and dispersed camping areas strictly prohibit draining grey water onto the ground. By pairing two of these adapters with commercial RV gear, you can build a fully legal, closed-loop greywater system for pop-ups with dual drains (sink and shower).

The DHG Tech Recommended Setup:

(2) DHG Tech 1.5" to 3" Adapters (One for the sink drain, one for the shower)

(1) Camco RhinoFlex 3-inch Wye Fitting (To combine the two drains into one hose)

(1) Camco RhinoFlex 3-inch Sewer Hose

(1) Camco Rhino 15-Gallon (or larger) Portable Tote Tank

Result: A completely sealed, high-capacity exterior holding tank system that keeps you legal and comfortable in the backcountry.

Features & Specs:

• Plug-and-Play: Replaces multi-piece DIY PVC setups with a sleek, low-profile adapter that looks like it belongs on your camper.
• Leak-Free Design: Precision-modeled threads ensure a watertight seal. In our field testing, this adapter outperformed standard injection-molded commercial fittings without weeping.
• Universal Compatibility: Fits vintage and modern campers with 1.5" MIP external drains (common on Coleman, Fleetwood, Jayco, and custom teardrops). Bayonet lugs are compatible with all standard 3-inch RV sewer hoses.
