The maximum safe water pressure for an RV is typically 40-60 PSI (pounds per square inch). Most RV manufacturers recommend keeping the pressure around 40-50 PSI to prevent damage to your plumbing system.
Why Water Pressure Matters in an RV
- 🚰 Too High Pressure (Above 60 PSI) – Can cause leaks, burst pipes, or damage to fittings.
- 🚰 Too Low Pressure (Below 40 PSI) – May result in weak water flow, making showers and washing dishes difficult.
- 🚰 Inconsistent Campground Pressure – Some RV parks have water pressure exceeding 100 PSI, which can damage your system.
How to Protect Your RV Plumbing
✔️ Use a Water Pressure Regulator – A preset regulator (45-50 PSI) or an adjustable one can help you control pressure.
✔️ Check Manufacturer Guidelines – Some RVs may handle slightly higher pressures, but it’s best to stay under 60 PSI.
✔️ Monitor Pressure with a Gauge – A simple inline gauge helps you keep track of the water pressure coming in.
