Last updated Aug 11, 2026

If you're living part-time in a small camper, one of the first things you notice is that not every RV has a full wastewater system. Some trailers and campers have just a single sink and no holding tank at all. That simple layout creates a simple problem: where does the sink water go, and how do you get it to the drain without a mess? The Camco Flexible Camper Drain Tap with Hose System is built to solve exactly that problem.

Quick verdict

With a price of USD 20.01, this Camco drain tap is an inexpensive solution for campers and RVs that have one sink and no holding tank. It's a complete system that includes a 25-inch ¾-inch inside-diameter hose and a drain trap made from chemical-resistant polymer, so you're not hunting for spare parts.

Who it suits

This works best for owners of small campers, pop-up trailers, van conversions, or vintage trailers where the kitchen or bathroom sink drains directly out. The sink end accepts a standard 1½-inch-11½ threaded drain fitting, so if your sink already uses that common size, installation should be straightforward. Because the system is designed for a single sink, it keeps the plumbing simple.

What stands out

The included 25-inch hose is a standout for a product at this price. That length lets you position the drain outlet with some flexibility, which matters when the sink is set close to the exterior wall. The construction is equally no-nonsense: the drain trap is a heavy-duty chemical-resistant polymer, and the evacuation flange is made from ABS, so the pieces that touch water are built to last. The complete kit approach means you get the drain tap and hose together in one package.

Trade-offs

There are a few things to weigh. The 25-inch hose is generous for a compact camper, but it won't reach across a large RV. If your layout has more than one sink or you're working with a holding tank, this product is not designed for that setup. It's also worth confirming that your sink's drain fitting matches the standard 1½-inch-11½ thread; if you have a non-standard fitting, you'd need an adapter or a different drain system.

Bottom line

For the camper owner with a single sink and no holding tank, the Camco Flexible Camper Drain Tap is a sensible, economical way to handle drain water. The chemical-resistant polymer trap and ABS flange give you confidence in the components, and the 25-inch hose covers typical small-camper installations. At USD 20.01, it's an easy decision for this specific use case.

Camco Flexible Camper Drain Tap with Hose System

This is the complete RV sink drain system you'd want for a single-sink setup without a holding tank. Its 25-inch ¾-inch inside-diameter hose gives you routing flexibility, and the chemical-resistant polymer trap is built to handle repeated contact with water and common sink residues. Keep in mind that the design targets a single sink and no holding tank, and the included hose is on the shorter side, so it fits best in compact campers and trailers. If your plumbing layout matches those parameters, this is a low-friction upgrade at USD 20.01.
