Drain Master 5202 Electric 3" Waste Valve with LED Indicator & Push-Button Operation

The Drain Master 5202 is a 3" 12V DC electric gate valve for RV black/gray tanks that opens and closes at the push of a button. The heavy-duty LED operator switch shows open/not-closed status at a glance, while stainless-steel gearing delivers fast, reliable actuation—typically in about a second. The system is plug-and-play with a simple two-wire hookup and includes a manual override so you can operate the valve if power is unavailable.

Why RVers choose Drain Master

• Push-button dumping: No crawling under slides to pull stiff cables.
• LED status: The switch light shows when the valve is open or not fully closed, preventing drive-off mistakes. :contentReference[oaicite:5]{index=5}
• Fast actuation: Opens/closes in about a second—reduces partial dumps and cable chatter. :contentReference[oaicite:6]{index=6}
• Manual override: Double-sided override with included 1/8" Allen key—operate even with no power. :contentReference[oaicite:7]{index=7}
• Durable drive: Stainless gearing handles frequent use and tank residue better than cable systems. :contentReference[oaicite:8]{index=8}

Compatibility & install notes

• Piping: Designed for standard 3" ABS tank plumbing. For 1-1/2" galley lines, use the Drain Master reducer kit (sold separately). :contentReference[oaicite:9]{index=9}
• Mounting footprint: Similar to manual valves; allow extra height for the motor head.
• Switch location: Can be mounted inside a compartment or interior panel; weatherproof construction for bay installs. :contentReference[oaicite:10]{index=10}
• Power: Fuse the circuit at 5A; keep wire runs tidy; avoid constant pressing—hold for ~1–2 seconds per operation. :contentReference[oaicite:11]{index=11}

Basic installation

1. Support the plumbing. Remove the manual 3" valve and clean sealing surfaces.
2. Install new seals, position the 5202 valve, and bolt through the flanges.
3. Mount the LED operator switch; run the harness to the valve and connect the plugs.
4. Connect 12V DC with a 5A fuse; test open/close (button press ~1–2 seconds).
5. Apply Dow 111 to seals as needed; verify no drips and proper LED indication.
