5 Spring RV Maintenance Tasks You Can't Ignore (Must-Do Checklist!)
1. De-Winterize Your Plumbing System
Getting your plumbing system back in working order is essential for ensuring safe drinking water and protecting your pipes.
Remove Antifreeze from Water Lines
Start by draining any non-toxic antifreeze from the water lines. Connect a drinking water hose to your city water inlet or fill the fresh water tank. Then, open all the faucets and flush the system until the water runs clear and no pink residue remains.
- Turn the water heater bypass valve back to its normal position.
- Flush the toilet until the water is completely clear.
- Run the outside shower to remove any antifreeze.
- Clear out the 12-volt pump by flushing it until the water runs clear.
Clean Your Water Tanks
Sanitizing your water system is key to preventing bacteria from growing during winter storage. Use this bleach-to-water ratio for effective sanitization:
| Tank Size (Gallons) | Household Bleach (Cups) | Water (Gallons) |
|---|---|---|
| 15-16 | 1/4 | 1 |
| 30-32 | 1/2 | 2 |
| 45-48 | 3/4 | 3 |
| 60-64 | 1 | 4 |
"It is important to circulate the bleach solution throughout the entire water system to ensure that no dangerous organisms remain that could recontaminate the system." - Tucker Ballister, Content Strategist, Camping World Blog
Let the bleach solution sit in the system for 3 to 12 hours. Afterward, drain the system completely and flush it with fresh water until there’s no bleach smell left. Once the system is sanitized, take the time to inspect all connections for leaks.
Check for Water System Leaks
Carefully inspect the plumbing for any leaks. Pay special attention to:
- Plumbing connections under sinks and behind toilets.
- Fittings and the tank of the water heater.
- Seals on the fresh and waste water tanks.
- Visible PEX tubing joints, typically in 3/8-inch or 1/2-inch sizes.
If the water pump cycles every 5–10 minutes with all faucets closed, it’s a sign of a leak. Look for soft spots, water stains, or other signs of hidden leaks on walls, floors, and inside cabinets. Address any issues promptly to avoid further damage.
2. Check Tires and Pressure
Taking care of your RV's tires is essential for both safety and performance. Regular checks can help you avoid tire-related issues and extend their lifespan.
Measure Tread and Inspect Sidewalls
Start by examining your tires for any signs of wear or damage. Run your hand along the sidewalls to feel for hidden problems. Be on the lookout for:
- Cuts or punctures in the tread
- Bulges or bumps on the sidewalls
- Cracks where the rubber is peeling or flaking
- Uneven wear patterns, which might point to alignment problems
- Exposed inner cords, which mean the tire needs immediate replacement
"During normal cornering, the tires and wheels experience a considerable amount of stress called 'side-load'. Therefore, the lug nuts on your recreational vehicle require periodic retorqueing." - Sunnyside-MOC
Monitor Tire Pressure
Keeping your tires properly inflated is key to safety and durability. Tire pressure can change by about 1 PSI for every 10°F temperature shift. Use these guidelines based on how you measure your RV's weight:
| Weight Measurement Method | Recommended Action |
|---|---|
| Individual Tire Position | Follow the tire manufacturer's inflation chart |
| CAT Scale | Weigh each axle (less precise but acceptable) |
| No Weight Data | Inflate to the maximum cold pressure listed on the tire's sidewall |
For accurate readings:
- Check tire pressure when the tires are cold
- Use a reliable digital tire pressure gauge
- Think about installing a Tire Pressure Monitoring System (TPMS) for real-time updates
Once you've confirmed the correct tire pressure, take a moment to inspect the lug nuts to ensure they're securely fastened.
Check Wheel Lug Nuts
Each wheel on your RV supports over 1,000 pounds. To keep everything secure, retorque the lug nuts after installation, then again at 10, 25, and 50 miles. Use a torque wrench and tighten in a star pattern. Be careful not to over-tighten, as this can damage both the lug nut and the stud. It's worth noting that underinflated tires account for about 75% of RV tire failures.
If you're unsure about your tire load measurements, professional services like Escapees Smart Weigh or RV Safety Education Foundation (RVSEF) can provide precise data.
3. Check Battery Health
RV batteries are the backbone of your vehicle’s essential functions. Keeping them in good condition not only prevents unexpected failures but also extends their lifespan.
Clean Battery Connections
Maintaining clean battery terminals is crucial for optimal performance. Here’s how to do it:
- Prioritize Safety: Always wear gloves and eye protection. Start by disconnecting the battery - remove the negative cable first, followed by the positive one.
- Thorough Cleaning: Create a mixture of baking soda and water (1 part baking soda to 6 parts water). Apply it to the terminals, scrub with a cleaning brush, then rinse and dry completely.
- Prevent Future Corrosion: After cleaning, apply dielectric grease or a battery terminal protector to keep corrosion at bay. This is particularly important for flooded lead-acid batteries, which are more prone to corrosion.
Once the connections are clean, move on to checking the battery’s voltage levels.
Check Battery Power Level
Knowing your battery’s voltage can give you a clear picture of its health. Here’s a quick guide:
| Battery State | Voltage Reading | Action Needed |
|---|---|---|
| Fully Charged | 12.6V or higher | No action needed - battery is healthy. |
| Partially Charged | 12.1V – 12.5V | Recharge is recommended. |
| Deeply Discharged | Below 12.0V | Recharge immediately. |
For accurate results:
- Disconnect the battery from all loads at least 24 hours before testing.
- Use a digital multimeter for precise voltage readings.
- Test the battery at room temperature.
- For non-sealed batteries, check the electrolyte levels.
Install New Batteries
If your battery shows signs of wear or reduced performance, it might be time for a replacement. Keep an eye out for:
- Decreased capacity or slower charging.
- Physical damage or sulfation buildup.
- Age exceeding the suggested lifespan.
- Persistent voltage problems.
Here’s a quick breakdown of battery types and their expected lifespans:
| Battery Type | Expected Lifespan | Maintenance Level |
|---|---|---|
| Flooded Lead-Acid | 3–5 years | High |
| AGM/Gel | 4–7 years | Medium |
| Lithium-ion | 10+ years | Low |
Keep in mind, batteries can lose about 1% of their charge daily while in storage. In cold conditions, a battery that’s 80% discharged can freeze at 19°F, potentially causing irreversible damage.
For a longer-lasting and more efficient option, consider upgrading to AGM or lithium-ion batteries. These newer types charge more efficiently and require far less maintenance than traditional flooded lead-acid batteries.
4. Check Roof and Seals
Your RV's roof is your first line of defense against water damage, making regular inspections essential to avoid expensive repairs down the road.
Look for Roof Damage
Start by setting up a secure ladder with a spotter for safety. Clean the roof thoroughly to reveal any hidden issues before inspecting. Keep an eye out for these common problems:
| Damage Type | Visual Indicators | Required Action |
|---|---|---|
| Material Failure | Cracks, tears, bubbles | Repair or replace immediately |
| Water Damage | Soft spots, sagging areas | Seek professional assessment |
| Aging Signs | Discoloration, fading | Monitor and plan for maintenance |
| Seal Issues | Peeling or separated seams | Reseal affected areas |
Pay special attention to areas around vents, air conditioners, and any roof penetrations. Also, check interior walls and ceilings for water stains, which could signal leaks. Once damage is identified, take steps to reinforce seals to prevent further issues.
Fix Roof Seams
To repair roof seams, gather the following tools:
- RV-specific roof cleaner
- Sealant designed for your roof type (EPDM or TPO)
- Caulking gun
- Putty knife
Start by cleaning the areas that need repair. Apply the sealant carefully, following the product instructions. For larger repairs, a product like Henry's 100% silicone roof patch (around $340.00 for a five-gallon bucket) can be a reliable option. Make it a habit to inspect seams every three months and after long trips to catch issues early. After addressing the roof seams, move on to cleaning and inspecting your slide-out covers for complete roof care.
Clean Slide-Out Covers
Follow these steps to clean your slide-out covers effectively:
- Fully extend the slide-out.
- Use a soft brush to remove debris.
- Wash with mild RV roof soap.
- Rinse thoroughly with clean water.
- Allow the cover to dry completely before retracting.
Regular cleaning helps prevent mildew and ensures the covers maintain their protective properties. Inspect the covers for tears or damage, and seek professional help if repairs are needed.

5. Clean the Water System
After checking your plumbing and batteries, it's time to make sure your RV's water system is clean and ready. A sanitized system with fresh filters ensures safe drinking water for your adventures.
Mix a Sanitizing Solution
To sanitize your water system effectively, you'll need the right ratio of bleach to water. Here's a quick reference:
| Tank Size (Gallons) | Bleach Amount | Water Amount |
|---|---|---|
| 16 | ¼ cup | 16 gallons |
| 32 | ½ cup | 32 gallons |
| 48 | ¾ cup | 48 gallons |
| 64 | 1 cup | 64 gallons |
Start by diluting the bleach in water before adding it to your fresh water tank. This step protects your plumbing and ensures the solution spreads evenly. Once added, run the mixture through all faucets until you notice a bleach scent. Let it sit for at least 5 hours - or better yet, overnight - for thorough sanitization.
"As long as it's mixed with the correct amount of water to obtain the right ratio, bleach is safe for all the components of your RV's water system, including the water pump." - Camping World Technician
Flush Out Old Antifreeze
Even if you've already removed antifreeze, this step ensures no leftover residue remains in your system. Position your RV near a sewer connection and follow these steps:
- Hook up the sewer hose and fill your fresh water tank.
- Open all faucets - sinks, showers, and exterior connections - and flush until the water runs clear, with no pink residue. Be sure to check both hot and cold lines.
- Keep an eye on the gray tank. Once it’s about two-thirds full, shut off the faucets and drain both the black and gray tanks.
- Repeat the process 2-3 times to ensure the system is completely clear.
Replace Water Filters
Fresh filters are key to maintaining clean, safe water. Stick to the following replacement schedule:

| Tank Valves | Rust, corrosion | Visible damage, loose fittings |
| Supply Lines | Wear, damage | Cracks, rubbing against edges |
| Appliance Fittings | Connection points | Loose fittings, corrosion |
"The easiest way to detect a propane leak is with your nose... It has a distinct smell like rotten cabbage, which can alert you to an RV propane leak." - Arnold Chapman, Founder of ELDFocus
If you smell propane or find a leak:
- Turn off all propane sources immediately
- Extinguish any open flames
- Open doors and windows for ventilation
- Exit the RV
- Call 911 for assistance
Check Propane Pressure
To ensure your propane system is functioning properly, use a manometer to measure the pressure. The ideal reading is 11 inches of water column (WC), though anything between 11 and 14 inches WC is acceptable.
"When you come back into the rig, the pressure should read somewhere between 11 inches and 14. 11 is the goal. 11 is perfection. 11 is what we aspire to. But anything between 11 and 14 is considered acceptable." - RV Repair Woman
Performing a pressure drop test is straightforward:
- Connect the manometer to a stove burner.
- Turn off the propane at the tank.
- Release pressure until it reaches 8 inches WC.
- Monitor for 3 minutes - if the pressure moves, you may have a leak.

Frequently Asked Questions About Spring RV Maintenance
How often should I inspect my RV's roof seals to avoid water damage?
To prevent water damage, it's a good idea to inspect your RV's roof seals at least twice a year. If you want extra assurance, consider checking them every three months, especially after heavy rain, storms, or harsh weather. Keep an eye out for cracks, gaps, or any signs of wear, and address any problems right away to ensure your RV stays protected and dry.
How can I tell if my RV's propane system has a leak, and what’s the safest way to check for one?
If your RV's propane system has a leak, you may notice a rotten egg smell (from the odorant added to propane), increased propane consumption, or error codes on appliances signaling low propane levels. These signs shouldn't be ignored, as propane leaks pose serious risks.
To check for a leak safely, start by turning off the propane tank. Use a manometer to conduct a pressure drop test - if the pressure drops significantly, there’s likely a leak. Another method is applying soapy water or a propane leak detection solution to the connections; bubbles will appear where the leak is. When in doubt, prioritize safety and reach out to a professional.
What should I do if my RV battery is deeply discharged and won't hold a charge?
If your RV battery isn't holding a charge and seems deeply discharged, the first step is to check its voltage with a multimeter. A fully charged lead-acid battery should read between 12.4 and 12.8 volts. If the reading is significantly lower, you’ll likely need a smart charger specifically designed to recover deeply discharged batteries. Standard chargers often can’t handle batteries with a voltage below 10.5 volts.
To try and revive the battery, connect it to a smart charger that supports low-voltage recovery, or use a jump-start from another battery. Let it charge for several hours. If the battery still won’t hold a charge after this, it might be sulfated or permanently damaged. In that case, replacing it is probably your best option. To avoid these problems in the future, make sure to perform regular maintenance and store the battery properly.
