RV Water Pressure Regulator

Overview

This is an adjustable, lead-free brass water pressure regulator designed for RV / camper / travel trailer fresh water systems. Its purpose is to reduce and control the incoming city water pressure before it enters your RV plumbing, protecting hoses, valves, and fixtures from overpressure damage. The unit features a built-in pressure gauge (liquid-filled) and a debris screen filter on the inlet.

It comes pre-set (factory) at ~45 PSI, but can be adjusted up (or down) up to a maximum of about 160 PSI for special use (though you should rarely need to run it that high).

Key Features

• Heavy duty brass / lead-free construction (less than 0.13% lead)
  
• Adjustable pressure range (factory ~45 PSI, adjustable up to 160 PSI)
  
• Liquid-filled stainless steel gauge (for more stable, long-lasting readings)
  
• Inlet debris screen / filter to catch particles before they enter RV plumbing
  
• Standard ¾″ garden hose / NH thread compatibility (inlet / outlet)
  

RV Use Cases

• At campsite hookups, to regulate city / campground water pressure to safe levels for the RV
  
• Monitoring actual incoming pressure via gauge, and adjusting if pressure fluctuates
  
• Preventing damage to RV plumbing joints, fittings, faucets, and water heater due to spikes
  
• Use during inspection or maintenance: verifying the regulator is functioning, checking for debris caught in screen
  

Common User Feedback

Pros:

• Durable brass body feels solid and well constructed
  
• Gauge gives a good, real-time reading
  
• The adjustable range gives flexibility
  
• Inlet screen helps catch grit before plumbing
  

Cons:

• Some users find the adjustment screw a bit stiff
  
• If pressure is naturally low, the regulator may reduce pressure further (some remove it temporarily)
  
• The gauge may lag or read slightly off if flow is very low
  

Best Practices

1. Install before the RV’s main supply line, typically at the spigot end, with the flow going from the campground supply into the regulator, then into your hose and RV.
   
2. Set pressure to a safe level (commonly between 40–60 PSI, depending on your RV’s plumbing specs). Check your RV’s manual for recommended max pressure.
   
3. Flush the regulator and check the screen periodically—especially at the start of a camping season—to remove debris.
   
4. Avoid setting pressure at extremes (e.g. 160 PSI) for regular use—run at moderate safe pressure to reduce stress.
   
5. Monitor gauge regularly, especially if you notice unusual sounds, drips, or leaks—large drops or fluctuations might signal clogs or malfunctions.
   

Inspector’s Note (RV Pro Solutions Insight)

As a Certified NRVIA Inspector, I strongly recommend installing a reliable pressure regulator such as this before any of your RV’s plumbing components. Many failures in RV freshwater systems originate from unregulated pressure surges at hookups (especially at campgrounds). The built-in gauge is a bonus, allowing you to verify that the delivered pressure stays within safe boundaries.
