Whether you live in a sunny climate or one with unpredictable weather, pool equipment maintenance is a crucial aspect of owning a swimming pool. Among the many maintenance tips offered to pool owners, one question frequently arises: Should I put a tarp over my pool equipment? The short answer is: it depends. From climate conditions and the type of equipment you own, to seasonal changes and long-term usage plans, several factors influence this decision. In this detailed guide, we’ll explore everything you need to know about covering your pool equipment with a tarp, including its benefits, potential drawbacks, and best practices for protecting your investment.
Why Pool Equipment Protection Matters
Pool pumps, filters, heaters, chlorinators, and control panels are the heart of any functional swimming pool. These components are not only expensive but also highly susceptible to environmental damage. Exposure to wind, rain, sun, humidity, and dust can:
- Corrode metal parts
- Decrease efficiency and lifespan
- Increase the likelihood of mechanical failure
- Create safety hazards
Proper protection is vital to preserve the integrity of your equipment and ensure it runs smoothly throughout the year. While a tarp may seem like a simple and cost-effective protective solution, it isn’t always the best approach — and sometimes, it can do more harm than good.
Is a Tarp Necessary for Your Pool Equipment?
Before jumping to cover everything in sight with a tarp, consider the following variables:
1. Climate and Seasonal Conditions
The climate you live in plays a major role in determining whether covering your pool equipment is advisable.
| Climate Type | Protection Recommendation |
|---|---|
| Sunny and Dry | Tarp not usually needed but limited sun protection may help with temperature control |
| Humid and Rainy | Partial cover may help prevent moisture buildup |
| Winter-Cold (Freezing Temperatures) | Insulated covers or full winterization is essential |
If you’re in a region with extended winters and below-freezing temperatures, your concern should be winterizing the equipment, not just covering it lightly with a tarp.
2. Type of Equipment
Different pool components have different tolerance levels to the elements. For example:
- Pool Pump: Should typically be covered to prevent water infiltration.
- Filter (Sand, Cartridge, or DE): Often left uncovered but benefits from some form of shelter.
- Pool Heater (Gas or Electric): May be vulnerable to moisture, so a cover helps.
- Control Panels and Automation: Must be protected from rain and dust at all times.
Tip: Always check the manufacturer’s recommendations. Some equipment warranties may void if improperly covered.
3. Presence of a Shelter or Cabinet
If your equipment is already inside a protective enclosure such as a shed, cabinet, or equipment pad with overhead coverage, adding a tarp may not be necessary — and could actually encourage condensation buildup, leading to mold or rust.
Benefits of Using a Tarp on Pool Equipment
Despite potential downsides, there are several clear advantages to tarping your pool equipment in the right conditions:
Prevents Water Damage
Rain is one of the biggest threats to exposed pool equipment. While many systems are designed to withstand moisture, prolonged exposure — particularly during severe weather — can lead to water entering sensitive electrical parts. A tarp helps divert water away and prevents potential malfunction.
Reduces Sun Exposure
While direct sunlight doesn’t impact mechanical systems quite as much as moisture, it can degrade the materials over time — particularly rubber gaskets, plastic housing, and control panels. UV damage is cumulative and can shorten the useful life of your equipment.
Discourages Dust and Debris Accumulation
Dust, pollen, leaves, and dirt can clog filters, reduce pump efficiency, and even cause wear in mechanical parts. A tarp can act as a preliminary shield against airborne and settling debris.
Low-Cost Protection Strategy
Compared to buying or building a permanent cover or enclosure, a high-quality tarp is an inexpensive and flexible option. It’s especially useful for homeowners preparing for short-term weather events, such as storms or extended rain seasons.
Risks of Inadequate Tarp Use
Before you begin draping tarps over your pool equipment, understand that misuse can actually cause problems:
Traps Moisture
This is the most common risk. If a tarp is not breathable or improperly ventilated, it may trap moisture from condensation or residual wetness after rain. This damp environment can contribute to mold growth, rust on metal parts, and possible electrical damage.
Promotes Mold and Mildew Growth
Moisture under closed tarps can develop mold and mildew — not only around the equipment but on the tarp itself. These organisms aren’t just unsightly; they can damage materials and be harmful to anyone who comes into contact with them.
Allows Dust to Settle Under the Tarp
Counterintuitively, an open-bottomed tarp can act as a funnel for dust and pollen, which settles right under the edges. You may end up with more buildup than if you had left the equipment open to the air.
Negatively Affects Equipment Access
A permanently covered system can make routine maintenance and equipment checks inconvenient. You don’t want a minor repair to turn into a major hassle just because the tarp was not easy to remove quickly.
Tarp Types and Material Considerations
Choosing the right tarp matters just as much as deciding whether to use one in the first place.
Waterproof vs. Water-Resistant Tarps
- Waterproof tarps are made from heavy-duty polyethylene or vinyl. They are excellent for fully sealing equipment from heavy rain or snow.
- Water-resistant tarps are often lighter and more breathable. These can be useful if you’re dealing with moisture from daily condensation or occasional showers, as they help avoid moisture buildup.
UV-Resistant Tarps
If you live in an area with heavy sun exposure, UV resistance is vital. Tarps without UV protection degrade faster, tearing easily and failing to shield your equipment long-term.
Mildew-Resistant Tarps
This feature is a must in humid climates. It prevents the tarp itself from becoming a breeding ground for mold and bacteria — a problem when stored over long periods.
Example Tarp Materials
| Material | Pros | Cons |
|---|---|---|
| Polyethylene (Blue Tarps) | Affordable, heavy-duty, waterproof | May degrade under UV light; not ideal for long-term outdoor use |
| Canvas | Breathable, durable in wind | Absorbs water; can develop mildew if not properly dried |
| vinyl-lined polyester | UV-resistant, waterproof, long-lasting | Costlier than basic tarps |
Proper Technique: How to Tarp Pool Equipment Safely
If you decide that covering your pool equipment is the right move, here’s how to do it correctly:
1. Clean and Dry the Equipment First
Moisture trapped under the tarp leads to mold and corrosion. Always ensure your equipment is completely dry before covering it, especially if tarping it for extended periods.
2. Use Secure Fastening Methods
Wind can easily tear loose plastic tarps or cause them to flap against sensitive components. Use bungee cords, tie-down straps, or weights to secure it in place, especially in exposed or windy locations.
3. Create a Sloped Cover Style
Ideally, the tarp should slope downward from the center to allow rainwater or condensation to drain off the edges rather than pooling on top. You can place a piece of PVC pipe across the middle of the tarp to elevate the center.
4. Leave Space for Ventilation
To prevent condensation buildup:
- Use breathable but water-resistant tarps
- Ensure air circulation around the equipment
- Open the tarp for a few hours every couple of days during longer tarping periods
5. Avoid Covering Control Panels Entirely
Electrical control panels need cooling airflow and access for operation. Cover these only partially using a panel-specific hood or weatherproof guard that prevents water but allows ventilation.
Alternative Protection Methods
While a tarp might do the job temporarily, permanent or semi-permanent solutions offer better long-term benefits:
PVC Equipment Enclosures
Custom PVC covers or enclosures provide sturdy, attractive, and functional protection. Many can be disassembled and stored seasonally.
Wood or Resin Equipment Boxes
These are designed specifically for pool equipment and often include ventilation holes, mesh windows, and locks to deter tampering.
Sheltered Equipment Pads
Inground installations with permanent awnings or roof protection are ideal if you have the space and budget. These structures also double as storage spaces for pool chemicals and gear.
Arcadia Covers or Retractable Canopies
For elegant and stylish protection, Arcadia-style covers offer semi-open but weather-shielded enclosures that enhance backyard aesthetics while safeguarding machinery.
When Not to Use a Tarp
There are situations where covering pool equipment with a tarp may not be recommended:
During Pool Heater Operation
Never cover a pool heater or other equipment while it is running. This can cause overheating, create a fire hazard, and damage tarp materials.
If the Tarp Isn’t Correctly Sized
A tarp that’s too small offers poor protection, while one that’s too large is awkward and risky. The ideal tarp should provide full coverage while allowing for airflow and access.
In the Case of Warranty Violations
Some manufacturers strongly advise against tarping equipment as it can void warranty protection. Always check with your supplier or read user manuals before covering.
During Winterization
Tarping alone is insufficient to protect equipment during freezing conditions. If you’re winterizing, consider full insulation, draining systems, and using protective boots or sleeves designed for the job.
Final Thoughts: A Customized Approach
So, should you put a tarp over your pool equipment? The answer isn’t a simple yes or no — it’s highly situational. A tarp can be an excellent short-term solution for added protection during storms, dusty seasons, or moderate rain. However, long-term or improper use can lead to damage and safety risks.
To summarize:
- Use a tarp if you experience heavy rainfall or plan short-term storage.
- Avoid tarps if your equipment already has housing or if your climate creates high humidity.
- Always use UV- and mildew-resistant tarps in sunny or humid environments.
- Secure the tarp properly and use breathable materials if possible.

- Consider permanent enclosures or sheltered pads for sustained equipment safety.
With smart, adaptable strategies, your pool equipment will remain efficient, durable, and ready for every swim session — no matter the weather.
- Ready to protect your investment
- Enjoy maximum efficiency and longer lifespan
- Avoid costly repairs through proper care
By assessing your needs and choosing a protection strategy that aligns with your climate, equipment, and usage habits, the decision to tarp — or not — becomes much clearer and far more effective for your unique backyard environment.
Why should I consider putting a tarp over my pool equipment?
Placing a tarp over your pool equipment offers protection against the elements such as rain, snow, sunlight, and debris. These elements can cause wear and tear on sensitive components like motors, filters, and electrical connections. In particular, moisture can seep into uncovered equipment, leading to rust, corrosion, and mold growth over time, which can affect performance and shorten the lifespan of your equipment.
Moreover, a tarp helps keep your pool equipment clean and free of leaves, dust, and dirt that may clog filters or reduce efficiency. This is especially useful during the off-season or if your equipment is stored outdoors without a dedicated enclosure. By using a tarp, you can reduce the time and effort needed for maintenance and potentially save on repair or replacement costs down the line.
Are all tarps suitable for use over pool equipment?
Not all tarps are created equal, and choosing the right one for covering pool equipment is important. A high-quality, waterproof tarp made from durable materials like polyethylene is ideal, as it will resist tearing and provide reliable protection against rain, UV rays, and temperature fluctuations. Avoid using thin plastic sheets or non-weather-resistant fabrics that may degrade quickly or tear under heavy conditions.
Proper fit is also essential. The tarp should be large enough to fully cover all exposed equipment but not so large that it creates flapping in the wind, which can cause abrasion or loosen the cover over time. Reinforced corners and grommets can make securing the tarp easier and more stable. Investing in the correct type of tarp ensures that your pool equipment is properly shielded from the environment without causing unintended damage.
How do I properly tarp pool equipment to avoid damage?
Properly covering pool equipment with a tarp involves more than just throwing it over the unit. First, ensure the equipment is dry before covering to reduce the risk of moisture buildup and mold growth underneath the tarp. Position the tarp so it fully covers all components, including the pump, filter, heater, and any exposed plumbing or electrical connections, while allowing for some airflow to prevent condensation.
Next, secure the tarp using bungee cords, ropes, or straps through the tarp’s grommets and anchor it to something stable like a nearby structure or equipment pad. Avoid pulling the tarp too tightly, which can tear seams or dislodge the equipment during windy conditions. Make sure to periodically check the tarp during the off-season to ensure it remains secure and in good condition.
Can covering pool equipment with a tarp cause condensation or moisture issues?
Yes, improper tarping can lead to condensation or moisture buildup under the cover, especially in humid climates or seasonal transitions. When warm air meets a cool surface beneath the tarp, the moisture in the air may condense and settle on the equipment. Over time, this condensation can lead to rust, corrosion, and the growth of mold or mildew that can damage internal components and degrade performance.
To avoid moisture issues, ensure the equipment is completely dry before placing a tarp over it. You can also elevate sections of the tarp slightly using blocks or poles to create air pockets for airflow, reducing the chance of trapped moisture. Using breathable tarps or leaving small openings along the sides can also help regulate humidity and maintain a drier environment around the equipment.
When is it necessary to remove the tarp from pool equipment?
The tarp should be removed when the pool is ready to be used again or during regular maintenance inspections. Before starting up the pool system, it’s crucial to remove the tarp entirely to avoid restricting airflow and to check for dust buildup, critter infestations, or any deterioration that may have occurred. Leaving the tarp on while operating the pump or heater can cause overheating, improper functioning, or blockages, potentially leading to equipment damage.
Additionally, during warm spells in the off-season, it’s wise to remove the tarp briefly to let the equipment breathe and inspect for moisture or pests. This helps maintain good condition and can prolong the equipment’s efficiency. After airing the equipment out, you can reapply the tarp if cold or wet weather is expected to return.
Can a tarp protect pool equipment from freezing temperatures?
A tarp alone may not be sufficient in extremely cold conditions to prevent freezing, but it can provide an added layer of protection by shielding equipment from wind, moisture, and direct contact with ice or snow. In climates where freezing is a concern, covering the equipment with a thick, insulated tarp in combination with other measures like draining water from pipes and applying antifreeze can help prevent internal damage from ice expansion.
It’s important to note that while a tarp helps reduce exposure, it doesn’t guarantee complete freeze protection. Additional methods such as insulating blankets, heat tape, or professional-grade covers designed for winterization should be used in tandem with a tarp. Always follow the manufacturer’s winterization instructions for your equipment to ensure the best insulation and protection during cold months.
What are the alternatives to using a tarp for covering pool equipment?
While tarping is an effective and economical option, there are several alternatives for protecting pool equipment. Permanent or semi-permanent equipment covers made from heavy-duty vinyl or canvas provide a tailored fit and enhanced durability. These covers often feature UV protection and weather-resistant seams, and some are designed with lockable zippers or Velcro closures for added security.
For long-term protection, building a shelter or enclosure around the equipment, such as a shed or custom-built cover, offers superior defense against the elements and potential vandalism. Some pool owners also opt for automatic pool covers or equipment enclosures that blend with the landscape for both aesthetic and functional benefits. The right alternative depends on climate, budget, and the level of protection needed for your specific setup.
