Having a pool in sunny Arizona is a joy, but it also means taking good care of your pool equipment. One crucial piece is the pool pump – the heart of your pool’s circulation system. If you’re a pool owner in Arizona, this casual yet informative guide will help you understand the different types of pool pumps (single-speed, dual-speed, and variable-speed), their pros and cons, and how to run them for optimal circulation and energy savings.
Single-Speed Pool Pumps (Old School Workhorses)
Single-speed pumps are the traditional, “old reliable” pool pumps. They have just one speed setting – on full blast or off. When on, they run at a constant high speed (determined by the pump’s horsepower). These pumps have been around for decades and are known for their simplicity.
Pros:
- Lowest upfront cost: Single-speed pumps are the cheapest to purchase initially, often a few hundred dollars for standard models . This makes them attractive if you’re on a tight budget or your old pump suddenly died and you need a quick replacement.
- Simplicity and reliability: With no fancy electronics or multiple settings, there’s less to confuse a homeowner. You basically turn it on or off, and it does its job. Fewer speed settings also mean fewer components that could fail – a reason these pumps have a decent track record for reliability over 3–10 years of life .
- Strong water flow: Running at full power means the pump provides strong circulation. This high flow rate can be beneficial for operating pool cleaners or water features without worrying about programming speeds.
Cons:
- High energy consumption: The downside of “full blast all the time” is a big electric bill. A single-speed pump uses the same high power regardless of the task, which wastes energy during simple filtration. In fact, running a single-speed pump might cost around $50 a month in electricity, versus only about $10 a month for an efficient variable-speed pump . Over a year in Arizona, that could add up to $1,000+ in energy costs, making it the second-largest energy user in many homes (only AC uses more) .
- Noisy operation: Single-speed pumps tend to be louder because the motor is always at max speed. You might hear it humming away in the yard, which can be annoying during peaceful evenings.
- Limited control: You can’t dial them down for gentler circulation. It’s all or nothing. This lack of flexibility means you might be pumping water faster than necessary, or you have to run it fewer hours to save energy (which could compromise water quality).
- Being phased out: New energy regulations have essentially made single-speed pumps obsolete for most pools. Since 2021, any new or replacement pool pump over 1 HP must be a more efficient model (usually variable-speed) to meet Department of Energy standards . So if your old single-speed pump fails, a pool pump replacement will likely be a dual or variable-speed unit.
Dual-Speed Pool Pumps (Two Modes for Flexibility)
Dual-speed pumps (aka two-speed pumps) offer two settings: low speed and high speed. They use a similar motor design to single-speed pumps, but you can flip a switch (or set a timer) to choose between a full-speed mode and a roughly half-speed mode . This gives a bit more flexibility for different needs.
Pros:
- Energy savings on low: Running at half-speed uses much less energy. Thanks to pump affinity laws, dropping the speed by 50% can cut energy use by about 75% . This means you can run the pump longer on low without a huge power bill. Many folks use the low setting for day-to-day filtration and only use high when necessary. Some homeowners even run their dual-speed pump on low nearly 24/7 for super-clear water and still save money over a single-speed.
- Quieter operation: On low speed, dual-speed pumps are much quieter. The motor hum is lower, which your neighbors will appreciate and you might barely notice it’s running.
- High speed when you need it: You still have the option to kick into high gear for demanding tasks. Need to vacuum the pool, run a pressure cleaner, or rapidly circulate chemicals after a treatment? Just switch to high for a while. It’s the best of both worlds in that sense.
- Moderate upfront cost: Dual-speed pumps cost a bit more than single-speeds, but typically less than variable-speed models. They’re a good mid-range investment if you’re not ready to splurge on the latest tech.
Cons:
- Still less efficient than variable: While two speeds are better than one, you can’t fine-tune a dual-speed pump beyond those two settings. If low is too weak and high is overkill, you don’t have a middle ground. Variable-speed pumps, by contrast, can dial in the perfect flow rate for any situation.
- Manual or additional controls needed: To take advantage of the low speed, you’ll need either a time clock or remember to switch speeds yourself. Without automation, some people might forget and leave it on high (losing the efficiency benefit) or always run low (and maybe not get enough circulation). Proper use is key to actually realizing the energy savings .
- Higher upfront cost than single-speed: You pay more for that extra capability. If you end up not using the low-speed setting much (for example, if your pool always needs high flow due to features or heavy use), then the extra cost isn’t worth it. In that case, you could question why you bought a dual-speed at all .
- Becoming less common: As variable-speed pumps have come down in price, dual-speed models are less popular than they used to be. Many manufacturers like Pentair, Hayward, and Jandy now focus more on single or variable-speed offerings. Still, you might encounter dual-speed pumps in existing pools or as an intermediate option if budget is a concern.
Variable-Speed Pool Pumps (High-Efficiency Champs)
Variable-speed pumps are the modern standard and the heroes of energy efficiency. Instead of just one or two speeds, these pumps can run at any speed you program (within their range, measured in RPM). They use advanced permanent magnet motors (similar to hybrid car engines) instead of old induction motors, which makes them super efficient . You can think of variable-speed pumps as the “smart pumps” – often with digital controls and even app connectivity on some models.
Pros:
- Big energy savings: This is the #1 selling point. By dialing in lower speeds for basic circulation, a variable-speed pump can use up to 80-90% less electricity than a comparable single-speed pump . In real dollars, that means what used to cost $50/month to run might drop to $10 or even less on your utility bill . Over time, those savings easily pay back the higher purchase price. Many pool owners see their investment paid off within a year or two of lower energy bills , especially here in Arizona where we run our pools for a long season.
- Fully adjustable flow: You can program the pump’s exact speed for different needs. For example, set a low RPM for gentle filtering overnight, a medium speed for daytime skimming, and a high speed for when you’re running the pool heater or water features. This dial-a-speed ability means no wasted energy – you use just enough power to get the job done. It’s great for integrating with pool automation systems as well.
- Quiet and long-lasting: At lower speeds, these pumps are extremely quiet – you might need to walk up to the equipment to check if it’s running. The motor’s cooler, lower-RPM operation also reduces wear and tear. Less heat and vibration = longer lifespan for the pump’s components . Many variable-speed units self-diagnose issues and protect themselves if something’s wrong, which can reduce repair needs.
- Meets current standards: Variable-speed pumps aren’t just nice to have; they’re often required for new pool installations or pump replacements. Recent DOE regulations (effective 2021) mandate that most pool pumps over 1 total HP meet minimum efficiency levels, effectively making variable-speed the default choice . So if you’re doing a pool pump replacement on an older pool, chances are you’ll be looking at a variable-speed model to comply with the law and to get utility rebates (if available).
- Top brands and tech: All the major pool equipment brands focus on variable-speed pumps. Pentair has its IntelliFlo series, Hayward offers the TriStar and Super Pump VS models, and Jandy’s variable-speed line is well-regarded. These brands design their pumps with user-friendly interfaces and features like built-in timers, priming functions, and even smartphone apps. In short, you have plenty of quality options from trusted names (Pentair, Hayward, Jandy, etc.) when you go variable-speed.
Cons:
- Highest upfront cost: There’s no way around it – variable-speed pumps cost more to buy. You might spend several hundred to a couple thousand dollars on a unit, depending on the model and horsepower. However, remember those energy savings! Over the life of the pump, it more than pays for itself in most cases . Some utility companies in Arizona even offer rebates for upgrading to a variable-speed pump because of the energy reduction.
- Complexity: With great power (or in this case, flexibility) comes a bit more complexity. Programming a schedule on a digital interface or syncing with your pool automation can be a learning curve for the less tech-inclined. Fortunately, the pumps do come with default settings that work for most pools, and your pool professional can always help fine-tune it.
- Potential compatibility issues: If you have older pool equipment, super low speeds might not activate certain features. For instance, some saltwater chlorine generators or heaters won’t run if the flow is too low . The solution is simply to schedule higher speeds when running those features. It’s a minor consideration, but something to be aware of during setup.
- Repair costs: These pumps have more advanced electronics (digital displays, onboard computers). If something goes wrong out of warranty, repairs or part replacements can be pricier than swapping out a simple single-speed motor. However, their improved durability often means fewer breakdowns in the first place. And given the energy savings, most owners find the trade-off well worth it.
How Long Should You Run Your Pool Pump Each Day?
Now that we’ve covered pump types, you might be wondering: How long do I need to run my pump every day for a clean and healthy pool? The answer depends on your pump type and your pool’s needs. Here in Scottsdale and Paradise Valley, our hot desert climate means we usually run pumps longer (especially in summer) than someone in a cooler climate might. The goal is to achieve at least one full turnover of your pool water (circulating all the water through the filter) each day, and often more during extreme heat. Here are some guidelines:
Single-speed pumps: A common rule of thumb is to run about 1 hour per 10°F of outdoor temperature during the swimming season. So if it’s 100°F out (not unusual for Scottsdale in summer!), you’d run the pump about 10 hours a day. Many pools in the Phoenix area end up running 8–12 hours daily in the summer months . In cooler winter months, you might scale back to 4–6 hours a day since water stays cleaner with less sun and heat . Always make sure the water stays clear and chemically balanced; if not, you may need to increase run time. (And if you’re battling algae or had a dust storm dump debris in the pool, you might run the pump 24/7 for a day or two to fix it.)
Dual-speed pumps: When using the low speed setting, you’ll generally want to run the pump longer than you would on high to achieve the same water turnover. Many Arizona pool owners will run low speed for 12 or more hours per day, and schedule an hour or two on high for tasks like skimming and cleaning. Because low speed uses so much less energy, you can afford to run it longer. In fact, one strategy is running on low continuously (24 hours) for superior filtration and only kicking up to high when needed . If running 24/7 isn’t feasible, aim for at least 12–15 hours on low. The key is ensuring your pool water gets filtered completely at least once (preferably 2+ times) a day. Adjust as needed if you notice water quality issues.
Variable-speed pumps: These are typically run the longest each day, but at very low speeds for much of the time. A common approach is to run a variable-speed pump ~12 hours per day in total, with a schedule like a few hours on higher speed and 8-10 hours on a low setting . For example, you might program 3 hours in the morning at a higher RPM to help clear debris (and to operate your pool cleaner or heater if needed), then 9 hours on a gentle low speed for constant filtration. Some pool owners even run their variable-speed pump 18 or 24 hours a day at ultra-low speeds – since it can cost pennies per hour, they prefer constant circulation to keep the pool pristine. The ideal run time will depend on your specific pump’s flow rates and your pool volume (and whether you have features like a salt chlorinator that need a minimum flow). But as a starting point, that 12-hour total (split between high and low) is a good rule that many Scottsdale and Paradise Valley pool owners follow.
Local tip: Because electricity is often cheaper at night or early morning (and our Arizona sun is brutal in the afternoon), consider scheduling most of your pump hours during off-peak times or overnight. You still want some daytime circulation (for skimming and preventing stagnation in the heat), but if you have a variable-speed pump, you can run it very low during expensive peak hours and save the higher speed circulation for the evening or morning. This strategy can improve energy efficiency without sacrificing water quality .
Every pool is a bit different. The above are general guidelines – you may need to tweak run times based on your pool’s size, how much sun it gets, how often it’s used, and even if trees drop lots of debris in it. Keep an eye on your water clarity and chemical levels. If everything stays stable, you’ve found your pump’s sweet spot. If not, try increasing run times incrementally. And remember, Paradise Valley pool maintenance routines in cooler months will look different than Scottsdale summer schedules – so adjust seasonally for best results .
