Trap, 25-inch hose, and ABS evacuation flange in one kit, it routes sink water straight out the sidewall or underneath the rig. Polypropylene trap, no metal to corrode, and it's made in the USA.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've got a small camper or a vintage trailer with a single sink and no holding tank, the Camco 37420 Flexible Camper Drain is about as simple as gray water gets. It's a complete drain system, trap and hose and evacuation flange all in one, built to route sink water straight out the sidewall or down underneath the rig. No plumbing puzzle, no holding tank to manage. Just a clean path for the water to leave.\u003c\/p\u003e\n\u003cp\u003eHere's how it works. The sink end threads onto a standard 1-1\/2 inch, 11-1\/2 thread drain fitting, the same size you'll find under most utility and camper sinks. From there the gray water runs through 25 inches of 3\/4-inch ID hose and out through the ABS evacuation flange. You mount the flange through the sidewall or the floor, and that's your drain. For a teardrop, a truck camper, or an older rig that was never plumbed for a black tank, this is the honest answer.\u003c\/p\u003e\n\u003cp\u003eThe parts are chosen for a reason. The drain trap is molded from chemical-resistant polypropylene, so soap, grease, and the usual sink chemistry won't eat it up. The evacuation flange is ABS with UV stabilizers, which matters when it's bolted to a sunny sidewall season after season. The whole system is rust-proof, top to bottom, because there's no metal in the water path to corrode. That's the payoff of an all-plastic drain. It just doesn't rot out on you.\u003c\/p\u003e\n\u003cp\u003eThe trap on the sink end does what a trap should. It holds a little water to block odors from climbing back up into the cabin, the same principle as the P-trap under your kitchen sink at home. On a small camper where the sink sits a few feet from where you sleep, that matters more than you'd think. Nobody wants to smell the drain at 2 a.m.\u003c\/p\u003e\n\u003cp\u003eBecause the hose is flexible 3\/4-inch line and not rigid pipe, you've got some freedom in how you run it. Snake it around a cross member, angle it toward the low side so it drains fully, or pick a flange location that suits the sidewall. Twenty-five inches isn't a huge run, but for a compact camper it's plenty, and flexible beats fighting with elbows and glued PVC joints in a tight cabinet.\u003c\/p\u003e\n\u003cp\u003eA quick word on fit. This is built for campers and RVs with a single sink and no holding tank, where the sink drains directly outside. If your rig captures gray water in a tank, you're running a different setup and this isn't it. But for the simple stuff, a galley sink in a teardrop, a hand-wash sink in a toy hauler, a utility sink in a small trailer, it's exactly right.\u003c\/p\u003e\n\u003cp\u003eOne practical note on using it. Since this drains straight out, you're releasing gray water wherever the flange points, so be mindful of where you're parked. At a hookup site you'll want a bucket or a proper drain below it. Boondocking, know the rules for the land you're on. It's the trade-off for skipping a holding tank. Simpler plumbing, but you're responsible for where the water goes.\u003c\/p\u003e\n\u003cp\u003eThe flange and cap come in white, the trap and hose in black, so it blends with most exterior panels without looking like an afterthought. Install is about as quick as it gets. Thread the trap onto the sink fitting, run the hose, mount the flange, and you're draining. No special tools, no glue-up on the water side. And it's made in the USA, which is worth noting on a part that lives outdoors and gets used every trip.\u003c\/p\u003e\n\u003cp\u003eBottom line, it's a cheap, simple, rust-proof drain that solves a specific problem well. If you've got a single sink and nowhere for a holding tank, this is the part you want. Keep a spare in the bin if you camp often, because a drain is one of those things you never think about until the day it splits.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eComplete rust-proof drain system, trap, 25-inch hose, and evacuation flange in one kit, with no metal in the water path to corrode\u003c\/li\u003e\n  \u003cli\u003e25 inches of 3\/4-inch ID hose gives you room to route around frame members and reach an off-center flange location\u003c\/li\u003e\n  \u003cli\u003eChemical-resistant polypropylene drain trap stands up to soap, grease, and everyday sink chemistry\u003c\/li\u003e\n  \u003cli\u003eABS evacuation flange with UV stabilizers holds up bolted to a sun-exposed sidewall season after season\u003c\/li\u003e\n  \u003cli\u003eThreads onto a standard 1-1\/2 inch, 11-1\/2 drain fitting, the common size under camper and utility sinks\u003c\/li\u003e\n  \u003cli\u003eBuilt-in trap blocks drain odors from rising back into the cabin\u003c\/li\u003e\n  \u003cli\u003eWhite flange and cap with black trap and hose blends with most exterior panels\u003c\/li\u003e\n  \u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Camco reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWho is the Camco 37420 drain designed for?\u003c\/summary\u003e\n    \u003cp\u003eCampers and RVs with a single sink and no holding tank, where the sink drains directly outside through the sidewall or underneath the rig.
