Warning: Excessive Water Pressure!
Campground pressure (80 PSI) exceeds your RV's safe limit (60 PSI). You need a water pressure regulator!

Water Pressure Guide
Ideal Range (PSI)
Safe for all RV plumbing systems. Optimal performance.
Caution Zone (PSI)
May stress fixtures. Use regulator for long-term protection.
High Risk (PSI)
Significant risk of damage. Regulator required!
Danger Zone (PSI)
Immediate damage likely. Never connect without regulator!
Why You Need a Water Pressure Regulator
RV plumbing systems are designed for pressures between 40-60 PSI, but many campgrounds provide water at 80-130 PSI or higher. This excessive pressure can cause serious damage to your RV's plumbing system, fixtures, and even interior components.
A water pressure regulator is a simple, inexpensive device that reduces incoming water pressure to a safe level. It's one of the best investments you can make to protect your RV, typically costing between $12-$55 but potentially saving you thousands in repairs.
Without Regulator
- • Burst pipes and fittings
- • Leaking faucets
- • Damaged water heater
- • Toilet seal failures
- • Interior water damage
With Regulator
- • Protected plumbing system
- • Extended fixture life
- • Consistent water flow
- • Peace of mind
- • Lower repair costs
Best Practices
- • Test pressure at hookup
- • Use brass regulators
- • Check regulator annually
- • Carry a pressure gauge
- • Replace every 3-5 years
Common Signs of High Water Pressure
⚠️ Warning Signs
- • Faucets leak or drip constantly
- • Water hammer (banging pipes when shutting off water)
- • Toilet runs continuously
- • Wet spots under sinks or fixtures
- • Spray from showerhead is too forceful
- • Unusual noises in plumbing system
🚨 Emergency Signs
- • Visible water spraying from connections
- • Water pooling inside cabinets
- • Burst pipes or blown fittings
- • Water heater relief valve releasing
- • Sudden loss of water pressure after hookup
- • Damaged or blown-out toilet seals
Important: If you notice any emergency signs, immediately disconnect from city water and assess the damage. High pressure damage can happen in minutes!
Frequently Asked Questions
Do I really need a water pressure regulator?
Yes! Even if your campground says they have "low pressure," it can vary throughout the day. A regulator is cheap insurance against potentially thousands in damage. Many RV manufacturers now require them to maintain warranty coverage.
What PSI should I set my regulator to?
Most RVs work best at 45-50 PSI. This provides adequate flow without stressing the system. Check your owner's manual for specific recommendations, but never exceed 60 PSI.
How do I test campground water pressure?
Use a water pressure gauge (about $10-15) that screws onto the campground spigot before connecting your hose. Test before every hookup, as pressure can vary significantly between sites and times of day.
Should I use a fixed or adjustable regulator?
Adjustable regulators ($35-55) offer more flexibility and typically last longer. Fixed regulators ($12-20) are cheaper but can't be adjusted if you need different pressure levels at different campgrounds.
How often should I replace my regulator?
Replace basic models every 2-3 years, brass/premium models every 5-8 years. Also replace if you notice inconsistent pressure, leaking, or if it's been subjected to freezing temperatures.
Can high pressure damage my water heater?
Absolutely. High pressure can damage the tank, fittings, and relief valve. Water heater repairs typically cost $400-1,200, far more than a quality pressure regulator.
Installation & Maintenance Tips
Installation Steps
- 1. Test campground pressure with gauge
- 2. Attach regulator directly to spigot
- 3. Connect water hose to regulator output
- 4. Set pressure (if adjustable) before turning on
- 5. Turn on water slowly and check for leaks
- 6. Verify output pressure at RV connection
Maintenance Checklist
- ✓ Inspect for cracks or damage before each use
- ✓ Check rubber washers and replace if worn
- ✓ Store in dry location during off-season
- ✓ Never leave regulator outside in freezing temps
- ✓ Test output pressure periodically
- ✓ Replace every 2-8 years depending on type
🛠️ Pro Setup
Many experienced RVers use a dual setup: a pressure regulator at the spigot AND a water filter between the regulator and RV. This provides both pressure protection and clean water. Always connect in this order: Spigot → Regulator → Filter → Hose → RV
Protect Your Investment
A water pressure regulator is one of the simplest and most cost-effective ways to protect your RV's plumbing system. For less than the cost of a single repair call, you can prevent thousands of dollars in potential damage.
💡 Remember: Test the water pressure at every campground before connecting. Pressure can vary significantly, even at the same park on different days.
