Campground water supplies regularly deliver 80, 100, even 120 PSI -- far more than most RV fresh water systems are designed to handle. The Valterra A01-2222VP screws on inline between the campground spigot and your fresh water hose, knocking incoming pressure down to a safe, steady level before it ever reaches your coach plumbing, fittings, or water pump. The built-in hose saver reinforces the connection point and reduces kinking and fatigue on the hose end -- a common failure point that most basic regulators ignore.
Most RV water systems -- tubing, fittings, toilet valves, water heater inlet connections, and pump bypass plumbing -- are rated for continuous service in the 45 to 60 PSI range. Unregulated campground hookups routinely exceed that by a wide margin. Over time (sometimes immediately), high pressure blows apart push-fit fittings, cracks plastic valve bodies, pops water heater pressure relief valves prematurely, and splits fresh water hoses at the connector end.
The A01-2222VP installs in seconds -- no tools required. It threads directly onto the campground spigot, then your fresh water hose threads onto the regulator outlet. The entire assembly stays outside the coach, so if anything ever needs servicing, you are not digging into a compartment.
Reduces high incoming campground water pressure to a safe level for RV plumbing systems, protecting fittings, hoses, valves, and the water heater.
Integrated hose saver reduces stress and kinking at the hose-to-regulator connection -- the most common wear point on hookup hoses.
Lead-free brass body meets drinking water safety standards, keeping your fresh water supply clean. Durable enough for full-time and seasonal use.
Standard 3/4 inch GHT (garden hose thread) male and female connections fit every standard campground spigot and RV fresh water hose without adapters.
Valterra's A01-2222VP is part of their core RV water accessories family, which includes basic inline regulators (A01-2221VP, no hose saver), flow-through regulators with gauges (A01-2224VP series), and this mid-tier model that adds the hose saver feature without the added bulk of an integrated pressure gauge. If you already know your campground hookup is rough on hose ends and you want reliable protection without monitoring the exact output PSI on a dial, the A01-2222VP is the right choice in that lineup.
If you also want a visible gauge to confirm output pressure (useful for diagnosing campground variability or for water-sensitive appliances like tankless water heaters), consider pairing this regulator with a separate inline pressure gauge, or step up to the Valterra gauge-equipped model.
Installation requires no tools and takes under a minute:
No PTFE tape or thread sealant is required for the GHT connections (GHT is a straight thread with a rubber washer seal). Make sure the rubber washer is present in your hose end before connecting.
Garden Hose Thread (GHT) is a straight thread sealed by a rubber washer. NPT (National Pipe Thread) is a tapered thread sealed with PTFE tape or pipe sealant. The A01-2222VP uses GHT on both ends -- the same thread on every standard campground spigot and RV city water inlet hose. No adapters needed for typical hookups. If your coach city water inlet uses a different thread, an adapter fitting is required (sold separately).
