A leaking or seized water heater drain valve is one of the most common maintenance headaches in any RV. Camco's replacement drain valve threads directly into the standard 1/2 in NPT port found on most RV water heaters, giving you a simple, reliable fix without special tools or fittings. Built from solid brass for lasting corrosion resistance, this valve seats with a watertight fit every time -- whether you're draining for the season, flushing sediment, or swapping in an anode rod.
The Camco 11703 (also sold under Camco SKU 80-8490) is a direct screw-in replacement for the factory drain valve on most 6- and 10-gallon RV water heaters from Suburban and Atwood/Camco. The 1/2 in NPT male threads match the industry-standard drain port, so installation is straightforward: drain the tank, unscrew the old valve, apply thread tape, and thread in the new one.
The solid brass construction resists the mineral buildup and corrosion that destroy plastic or pot-metal valves over time. The gold finish makes the valve easy to spot during your pre-winterization walkthrough, so you're not hunting for the drain in the dark.
Corrosion-resistant brass construction withstands repeated draining cycles and resists mineral scale better than plastic alternatives.
Industry-standard thread size fits the drain port on most 6- and 10-gallon RV water heaters directly -- no adapters needed in most installations.
Precision-machined seat creates a reliable shutoff. Apply PTFE thread tape to the male threads for a leak-free installation.
Hand-tighten plus a quarter-turn with a wrench is all it takes. Replaces a seized or leaking factory valve in minutes.
