Campground water supplies can surge well above 100 PSI -- far more than any RV plumbing system is designed to handle. The Camco 40143 drops that pressure to a consistent 40-50 PSI before it ever reaches your coach, protecting fittings, hoses, water lines, and appliances from costly pressure-related failures.
High campground water pressure is one of the most common -- and most overlooked -- causes of RV plumbing damage. A single pressure spike can blow a fitting, crack a valve seat, or rupture a fresh water hose. The Camco 40143 installs in seconds between the campground spigot and your RV inlet hose, acting as a constant pressure buffer every time you hook up.
This is a passive, fixed-output regulator. No adjustment required -- just thread it on and connect your hose. The blue plastic housing is easy to spot in your gear bag and is rated for outdoor use.
Automatically limits incoming water to a safe operating range for standard RV plumbing systems, regardless of supply pressure.
Female inlet threads onto the campground spigot; male outlet accepts your standard 5/8" or 3/4" RV drinking water hose -- no adapters needed.
Lightweight, corrosion-resistant plastic construction handles outdoor exposure. Blue color coding makes it easy to identify in storage.
Built for seasonal outdoor use at full-hookup campsites, RV parks, and campgrounds. Rated for outdoor installation at the spigot connection point.
Most RV fresh water systems are engineered for 40-60 PSI. Municipal and campground supplies routinely deliver 80-100 PSI or more, especially during off-peak hours at night. Over time -- or in a single surge -- that excess pressure stresses every component downstream:
A regulator like the 40143 is a low-cost insurance policy that pays for itself the first time it prevents a fitting failure inside a wall or under a slide.
