Maximize Your RV Shower Experience: Low Water Pressure Fixes
Water Pressure Problems
Low water pressure is a common headache for RV owners. Unlike home showers, which typically have steady pressure, RV systems usually operate at 40–50 psi , making pressure issues more likely.
Why Pressure Gets Low
Several things can cause weak water flow in your RV shower. A frequent issue is the campground's water supply. Using a pressure gauge can quickly identify if the incoming water is the problem.
The system itself can also contribute. Kinked or bent hoses can block flow, while clogged filters can limit pressure. Over time, water pumps may lose efficiency, especially in older RVs. Even minor leaks, like cracks in tubes or worn-out fixtures, can reduce pressure - and these problems often creep up gradually.
How to Fix Low Pressure
Solving low water pressure requires careful troubleshooting and repairs:
- Replace filters regularly: Swap out your RV water filter every 3–6 months to avoid buildup that slows water flow.
- Inspect hoses and lines: Look for kinks or damage in water lines and repair or replace them as needed.
- Check the water pump: Test the pump to ensure it’s working consistently.
You can also upgrade to a pressure-boosting showerhead, like the Ecocamel Jetstorm ($48.00), which uses AirCore technology to maintain pressure while conserving water.
When using campground hookups, try to avoid running multiple water fixtures at the same time. If low pressure at campgrounds is a recurring issue, consider investing in a water pump booster - it can make a big difference. These steps will help ensure your RV shower performs better, even in challenging conditions.
Hot Water Issues
RV water heaters are much smaller than those in homes, usually holding just 6–10 gallons . This means shower time is limited, as these tanks run out of hot water quickly - often in just a few minutes. Even larger RV tanks (4 to 16 gallons ) can't match the capacity of home systems.
Small Tank Limitations
Atwood water heaters use aluminum cores, which don’t require anode rods, while Suburban models rely on porcelain-lined steel tanks that need anode rods for protection . While both designs have their strengths, neither solves the issue of limited capacity.
Here are some common problems with RV water heaters and how to identify them:
| Issue | Likely Cause | Check |
|---|---|---|
| No hot water at all | Thermostat or heating element failure | Test both gas and electric modes |
| Popping sounds | Mineral buildup in tank | Check for sediment accumulation |
| Whistling noises | Debris in check valve | Inspect valve for blockage |
| Inconsistent temperature | Bypass valve issues | Verify valve position |
If you're struggling with these limitations, there are ways to make your hot water last longer.
Making Hot Water Last
"If there's no hot water on either gas or electric, the most likely problem is the thermostat. If you get hot water on gas, but not on electric, the typical culprit is the heating element inside the heater" .
Here are a few options to stretch your hot water supply:
- Install a tankless water heater: These systems provide hot water on demand, so you’ll never run out . While the upfront cost is higher, they can be a worthwhile investment for consistent hot water.
- Upgrade your showerhead: Using a water-efficient model, like the Ecocamel Jetstorm Plus ($56.00), can help reduce water usage without sacrificing pressure.
- Perform regular maintenance: Flush the water heater regularly to clear out mineral deposits that can lower efficiency . For Suburban models, replacing the anode rod periodically helps prevent corrosion .
Direct Spark Ignition (DSI) systems are another upgrade worth considering. Unlike older pilot light models, DSI systems are more efficient because they don’t waste gas when not actively heating .
Small changes in your habits can also make a big difference. For example, cutting your shower time by just two minutes could save up to 150 gallons of water each month . Turning off the water while soaping up is another simple way to stretch your hot water supply without sacrificing comfort.

Hard Water Problems
Hard water is a frequent issue for RV owners. Minerals like calcium and magnesium in the water can create problems for your RV's plumbing system.
Hard Water Damage
Hard water impacts your RV's plumbing in visible and functional ways. The first signs often include white spots and scale buildup on faucets and showerheads. Over time, these mineral deposits can reduce water flow and overall system efficiency.
| Problem Area | Impact | Early Warning Signs |
|---|---|---|
| Showerhead | Reduced flow, clogged ports | Weak or uneven spray pattern |
| Water Heater | Decreased efficiency | Longer heating times |
| Plumbing Lines | Restricted flow, potential damage | Decreased water pressure |
| Fixtures | White residue, soap scum buildup | Spotty appearance after drying |
"You need to verify what is in your water. Hard water means calcium or magnesium dissolved in the water. But water with many different minerals dissolved in it can leave white stains when it dries."

Saving Water
Using water wisely in your RV shower helps you stay off-grid longer while improving your overall experience. Along with managing pressure and temperature, conserving water is a crucial part of making the most of your RV setup.
Tank Size Limits
Your water tank's size determines how long you can go without refilling. On average, an RV user needs about 8 gallons of water daily - split between 4 gallons for personal tasks and 4 gallons for shared needs . For perspective, an 8-minute shower with a standard 2.5 GPM showerhead uses around 20 gallons of water. Switching to a low-flow 1.8 GPM showerhead reduces that to 14.4 gallons .
Water-Saving Methods
To make your water supply last, consider upgrading your hardware and adopting smarter habits. Here are some practical options:
- Showerheads: The Niagara Conservation Earth Spa showerhead runs at just 1.25 GPM . The Ecocamel Jetstorm Shower Head uses AirCore Technology to maintain pressure while cutting water use .
- SHOWERMI$ER System: This system recirculates cold water back to the fresh tank during the heat-up phase, saving up to 40% of both fresh and gray water capacity .
- The "Navy Shower" Technique: Wet yourself, turn off the water while lathering, then rinse .
- Water Pressure Regulators: Install a regulator between your water source and hose to keep flow levels efficient .
For those seeking versatile options, the Oxygenics Fury RV and BodySpa Adventure showerheads deliver a 1.8 GPM flow, multiple spray settings, and are WaterSense certified .
To stretch your water supply further during extended trips, consider using campground showers when available and repurpose shower water for tasks like flushing the toilet .
