Understanding Your RV Water System and Why Pressure Regulators Matter

Before we get into the different water pressure regulators, it is important to understand how your RV’s water system works. Whether you’re using a city water connection or your freshwater tank, the pressure in the pipes determines how well your system is going to function. Here is a quick breakdown of the RV plumbing system:

How does an RV Water System Work?

Like a home, an RV has a water system that is designed to provide safe, clean water that you can cook with, clean with, shower with, and drink. Each RV is unique, but most systems include these main parts:

• City Water Connection– This allows your RV to hook up directly to the city water through a spigot. If you use a city water connection, you don’t have to fill your freshwater tank or use your pump to create pressure. When you connect to the city water connection, you also get the water pressure that comes with it. This can sometimes be damaging to your plumbing.

• Freshwater Tank– The freshwater tank is a separate onboard tank that stores clean water in case you are camping, and there aren’t any city water hookups. Many people who boondock or camp off-grid rely on their freshwater tanks for their water supply.

• Water Pump– Your water pump draws water from your freshwater tank and provides pressure when you are not connected to a city water supply.

• Pipes & Fittings– Your pipes and fittings allow for water to be distributed throughout your RV. The pipes and fittings connect to your sinks, showers, toilets, and any appliances that use water.

• Water Heater– You may have an electric or propane powered water heater in your RV. The water heater heats up the RV’s water by either using r in your RV system and provides how water for washing dishes, showering, and cleaning.

Why Water Pressure Can Be a Problem

Campgrounds May Have Unpredictable Water Pressure

• Some campgrounds can have high water pressure that exceeds 100 PSI, which is too high for RVs and can easily burst pipes or loosen fittings.

RVs Use Lightweight Plumbing

• Most traditional homes use rigid pipes made from copper or PVC. RVs use PEX, because it is lightweight. PEX is great, but it can’t handle excessive water pressure.
• Over time, higher water pressure can cause PEX pipes to crack or weaken, which can cause slow leaks.

Campgrounds Can Have Fluctuating Water Pressure

• Large RV parks may have fluctuating water pressure that ebbs and flows depending on peak usage times (mornings and evenings when people shower).
• If you don’t have a water pressure regulator installed, you could easily have an unexpected surge of water pressure that can harm your plumbing.

Why Every RV Needs a Water Pressure Regulator

• Protects Your Plumbing- Prevents burst pipes, leaks, and damage.
• Keeps The Water Flow Consistent- No more issues with fluctuating faucet pressures. Get the same incoming pressure every time you open the faucet.
• Prevents Costly Repairs- Replacing RV plumbing and water damage can cost hundreds, if not thousands of dollars.
• Works at Every Campground: No matter where you hook up your RV, the water pressure will be at a safe level.
• Insurance Reasons: Some insurance companies may deny damage claims if the owner did not take reasonable measures to prevent the damage from happening (e.g., using a regulator).

How to Install Your RV Water Pressure Regulator: Easy 7-Step Guide

Now that you’ve invested in a water pressure regulator, what is next? Here is a step-by-step guide for a hassle-free installation:

Tools You Will Need

✅ RV water pressure regulator (adjustable or fixed)
✅ Flathead screwdriver (for adjustable regulators)
✅ Teflon tape (to prevent leaks)
✅ Drinking Water Hose (with NH threads)

Installation Steps

1. Flush the line 

Go to the spigot and remove any debris in the opening. Once the spigot is clear, turn the water on and let it run until the water is clear. Sometimes, there is rust build-up and debris in the water line, which will make it look muddy. You do not want this in your water lines, so flush first!

2. Locate and turn off your external source of water: 

The city water hookup should have a spigot with a valve. If there isn’t one, check to see if there is a water shut-off valve nearby.

3. Disconnect the RV Water Hose. 

Remove any hoses or attachments connected to the water spigot.

4. Apply Teflon Tape. 

Wrap layers of Teflon clockwise around the threads of the water hookup. This will create a secure, watertight seal.

5. Attach the RV Pressure Regulator. 

Screw the Female end of the RV pressure regulator onto the water hookup. However, when doing this, ensure it is snug but not excessively tight.

6. Make the hose connections.

Connect your drinking water hose to the outlet side of the regulator. If you are using a water filter, install it after the regulator.

7. Turn On the Water Supply…Slowly

Turn on the water supply to pressurize the system. Do this slowly to avoid introducing a water hammer. Inspect the regulator and connections for leaks. Tighten any loose connections as necessary. 

– For adjustable water pressure regulators: Turn on the water pressure and read the gauge. Increase the psi regulator by using a flathead screwdriver. Stop once you have good flow, ensuring not to exceed max pressure. Refer to the product instructions and RV Owner’s manual for the recommend

8. Check For Leaks and Make Adjustments

Check your connections for any leaks and tighten if necessary.

Also, if you have an adjustable regulator, read the gauge and increase the PSI regulator (as needed) using a flathead screwdriver. Do not exceed the maximum recommended pressure, and always refer to the product instructions and your RV Owner’s manual for recommended PSI.

Pro Tip: If you’re storing your RV in freezing weather, always remove your regulator to prevent cracking from ice expansion.

How Can I Increase Water Pressure?

You have connected to the residential water system. So, why do you still have low water pressure? There are a few ways you can troubleshoot low flow:

• Check your water hose for kinks.

• Test the campground’s incoming water pressure with a gauge directly at the spigot to confirm the problem is not within your RV’s water system.

• Check different fixtures to see if the water pressure problem is everywhere. Look throughout the entire water system. Does your toilet AND kitchen sink have low pressure?

• Check to see if the in-line water filter has a clog. Try flushing out the clog. If flushing does not work, it may be time to replace the filter.

Check to see if the low pressure is coming from the city water outlet. If so, you may have to fill your RV’s fresh water tank and use your onboard water pump.

Common RV Water Pressure Regulator Mistakes to Avoid

A few common mistakes can be made while hooking up or using RV regulators. Avoid these and protect your plumbing:

Forgetting to Check Campground Water Pressure First

• Some campgrounds have high pressure (100+ PSI), while others have low pressure (20 PSI).
• Always check with a water pressure gauge before hooking up.

Overtightening the Regulator

• Brass regulators can crack or strip the threads if overtightened.
• Hand-tighten only, and use a wrench if necessary for a snug fit.

Using a Cheap Plastic Regulator

• Plastic regulators crack easily and can leak or fail over time.
• Always choose lead-free brass regulators for durability.

Leaving the Regulator on in Freezing Weather

• Water expands when frozen, which can crack the regulator.
• Always remove your regulator when cold camping or storing your RV in the cold.

Not Using a Dedicated Drinking Water Hose

• Regular garden hoses contain chemicals that can leach into drinking water.
• Use a BPA-free, lead-free RV drinking water hose.

RV Water Pressure Regulator FAQS

What are the recommended water pressure levels?

The usual recommendation is 40-50 psi of water pressure. The maximum water pressure should not exceed 60 psi. Always keep your water pressure at a safe level. Always refer to your RV Owner’s Manual for the recommended PSI.

Should I Get an Adjustable or Fixed Regulator

Both are great options. Pre-set regulators are a no-fuss option. You just set it and forget it, but the PSI has no control. An adjustable regulator costs a little more, but allows you more control because you can adjust the pressure based on your needs.

How Can I Tell if My Regulator Is Failing?

Signs your water pressure regulator needs replacement:

• Water pressure has suddenly dropped.
• Leaks are forming around the regulator.
• The regulator gauge isn’t accurate or shows incorrect PSI.

Can I Use a Water Pressure Regulator With an RV Water Filter?

Absolutely! I am one of the many RVers who does this. Just make sure you install the filter AFTER the regulator so you get the appropriate water pressure.

Should I Remove My Regulator for Winter Storage?

Yes! When you store your rig in the cold months, always detach any regulators and filters. Leaving these attached can cause them to crack.

What Additional Tools Will I need for my Water System?

Your brand new RV won’t likely come with everything you will need for your first camping trip. You will need to pick up an RV drinking water hose so that you can actually hook up to water. In addition to the hose, I strongly recommend obtaining a water filter to ensure you are drinking safe water.
