A campsite water supply can deliver more pressure than an RV's freshwater plumbing is designed to handle. Valterra makes several regulator styles, including fixed 40–50 PSI models, higher-flow 50–55 PSI models, gauge combinations and a user-adjustable design. The right choice depends on the RV manufacturer's allowable water pressure, desired hose arrangement and whether you need an adjustment or gauge.

Valterra pressure regulators by exact part number

Use the published regulator rating below, rather than the colour or shape of the fitting, to compare these models. The listed output ranges describe regulated water pressure—not an instruction to increase the RV's plumbing pressure to that value.

Valterra MPN Pressure setting Regulator design Gauge? Distinguishing feature
A01-1120VP 40–50 PSI Fixed No Standard fixed brass regulator
A01-1122VP 50–55 PSI Fixed, high flow No High-flow fixed brass regulator
A01-1114VP 50–55 PSI Fixed, high flow No High-flow stainless-steel regulator
A01-1124VP 40–50 PSI Fixed Yes Fixed brass regulator with gauge
A01-1117VP User-adjustable Adjustable Yes Adjustable brass regulator with gauge
A01-2222VP 50–55 PSI Fixed, high flow No 90-degree high-flow brass regulator

Which regulator style best suits the hookup?

Standard fixed pressureA01-1120VP is a lead-free brass 40–50 PSI regulator without a gauge. The A01-1124VP has the same published output range with a built-in gauge.
Higher-flow, fixed pressureA01-1122VP uses lead-free brass, while A01-1114VP has a 304 stainless-steel body. Valterra rates both at 50–55 PSI and describes approximately 15–20% higher flow than its standard regulators.
Adjustable output with gaugeA01-1117VP has a flathead-screwdriver adjustment and visible pressure gauge. Set it to the RV's specified limit; Valterra advises against settings above 60 PSI and directs owners to their RV manual.
Angled water connectionA01-2222VP adds a 90-degree brass connection for a more convenient hose direction, with fixed 50–55 PSI output. Valterra explicitly says this model is not recommended for older RVs.
Important pressure distinction: A higher-flow regulator is not automatically appropriate for every RV. Confirm the freshwater system's rated inlet pressure and hose fittings. Valterra says its 90-degree 50–55 PSI model does not reduce pressure when the incoming pressure is already below 50 PSI; a regulator does not boost low campsite water pressure.

Before connecting at the campsite

  1. Look up the RV manufacturer's maximum permitted city-water pressure, especially for older plumbing.
  2. Identify the exact regulator MPN and whether its output is preset or adjustable. A gauge-equipped fixed regulator is not automatically adjustable.
  3. Inspect the campground tap, hose washers and city-water inlet for compatible connection threads and a sound seal.
  4. Where the manufacturer supplies a screened washer, keep it installed and inspect it for debris.
  5. Connect according to the product instructions, check for leaks and monitor the gauge where present. Do not use the regulator to compensate for damaged or leaking RV plumbing.

Common regulator questions

Are A01-1120VP and A01-1122VP the same regulator? No. The first is Valterra's standard 40–50 PSI model; the second is a high-flow 50–55 PSI model.

Does the gauge on A01-1124VP allow pressure adjustment? No. A01-1124VP has a gauge but uses fixed regulation. A01-1117VP is the adjustable model in this comparison.

Will a 50–55 PSI regulator improve every RV shower? Not necessarily. Available campground supply pressure, fixture restrictions, hose and filter flow, and the RV pressure limit all affect the result.
