If your inground pool pump suddenly stop working, you might think of can you use above ground pool pump for inground pool? This is a common question many pool owners face when an equipment emergency arises.
This guide will help you determine if repurposing your above ground pump is a viable option while a new inground pump is on backorder and learn how to lower alkalinity in pool. We’ll examine the main differences between these pumps and what factors limit their interchangeability.
We’ll break down exactly how these pumps vary in their water handling abilities. You’ll learn potential signs of overworking that could lead to overheating and failures.
Difference Between Above Ground and Inground Pool Pump
Inground pumps typically have higher flow rates, greater head pressure abilities, longer cord lengths, compatibility with rigid plumbing, and more durable construction for continuous use, compared to above ground pumps which generally have lower performance specifications suited for small temporary pools.
Flow Rate
Inground pumps are sized to shift water volumes continuously, rated between 30-50 gallons per minute (GPM) on average. They rely on higher flow to power filtration systems cleaning several thousand gallons daily. This consistent flow sustains a pool’s chemistry balance. Above ground pumps often top out around 20-30 GPM, meeting needs of smaller above ground pools holding much less water.
Head Pressure
Related to flow is pressure, or head. Head represents resistance in the plumbing that a pump must overcome to displace water through pipes. Inground setups involve lengthy underground pipe runs around perimeter decks or through connections in a deep end, necessitating pumps developing 30-60+ feet of pressure. Above ground versions deliver pressures adequate for short hosing, generally 5-30 feet.
Piping & Fittings
While inground pumps connect directly to rigid schedule 40 PVC plumbing, the ports and fittings of an above ground counterpart may not properly mate. Above ground pumps utilize inexpensive slip fittings compatible with flexible hosing, not rigid PVC. The hydraulics are different, risking leaks or damage without adapting connections.
Voltage
The grunt needed to power an inground pump’s higher flow and pressures means they usually run on 240V single phase. This delivers more horsepower than the 120V standard for above ground pumps which push lighter loads. Running a 120V pump at an inground system’s demands could overwork and burn out the motor.
Cord Length
240V inground pumps require long 50+ foot power cords to reach the filtration devices, heater, and other remote components within the pad. The shorter 25-50 foot cords of above ground pumps may not stretch far enough without risky extension cords.
Durability
Pumps spend their lives submerged in pool water and weather elements, necessitating resistant steel, heavy plastics, and leak-proof gaskets. Above ground versions utilize slightly more lightweight and porous materials intended for occasional seasonal use rather than continuous outdoor duty.
Size & Clearances
Inground chambers house pumps and equipment designed to optimize space while allowing ventilation, access panels, and routine maintenance like basket cleaning. An above ground pump may be larger with poorer clearances, obstructing flow or block essential servicing.
Filtration Integration
Inground systems fully integrate heaters, filters, chemical controllers and more in series with the pump. The pump must power this entire process. Above ground pumps stand alone to circulate water only through basic filtration like sand filters requiring a few psi.
Warranties
Reflecting continuous use versus seasonal, inground pump warranties commonly cover 5 years of operation while above ground pumps warrant 1-3 seasons. The engineered componentry for long-term duty receives more extensive validations and product testing.
Sizing By Gallons
The volume of water in an average 18,000 gallon inground pool significantly dwarfs that of most 8×12 up to 18×33 foot above ground models holding 2,000-12,000+ gallons. An undersized pump couldn’t keep pace with turnover needs.
can you use above ground pool pump for inground pool
Yes, use an above ground pool pump for an inground pool, but only in emergency scenario. Because there are some technical factors to consider:
Above ground pump may technically power up and circulate water when connected to an inground pool’s plumbing, its performance will likely be inadequate or potentially damaging depending on the pump specifications.
Flow rate, head pressure, voltage requirements, Cord length, and filter integration need to be thoroughly reviewed to determine if the above ground pump has the hydraulic horsepower required. Its maximum capabilities for handling gallons per minute and overcoming plumbing resistance must meet or exceed the demands of the inground setup.
Provided the above ground pump is rated for similar flows above 30 GPM and heads above 30 feet as a standard inground pump, temporarily using it may work as a stopgap measure. However, voltage is usually the showstopper, as most above ground pumps run on 120V and cannot withstand the load of larger systems running on 240V long-term.
How to Choose the Best Pool Pump for Your inground swimming pool
As an inground pool owner, maintenance starts with selecting the right circulation pump. This vital piece of equipment keeps the water clean and balanced for safe recreation. With so many pump models available, how do you pick one that’s properly sized and suited for your pool’s specific requirements? Let’s learn the top factors to consider.
Pool Size and Gallon Volume
The first step is accurately measuring your pool’s length, width and average depth. Then use the volume calculation formula:
length x width x average depth x 7.5 = total gallons.
This size dictates the necessary pump circulation rate. For reference, most medium in-ground pools hold 15,000-30,000 gallons.
Flow Rate and Turnover Time
For effective water filtration, the pump must move the whole pool’s water volume within 6-12 hours. As a general guideline, inground pumps need a minimum flow rate of 30 gallons per minute (GPM) and are sized between 30-50+ GPM depending on pool size. Higher flow rates turn over larger volumes more efficiently. Consider adding a few GPM for extra capacity as the pump ages.
Head Pressure Rating
Because inground plumbing runs underground between components, the pump must generate sufficient pressure, measured in feet, to push water uphill through pipe resistance. Plan for at least 30 feet of static head, and up to 60+ feet depending on layout complexity. Consult a pool pro to size your pressure needs precisely.
Voltage Requirements
Nearly all inground pumps operate on 230V or 240V household current for their sizeable loads. Confirm your electric panel has the correct configuration and wire gauge for sustained use. Improper voltage risks damage and voids manufacturers’ warranties.
Design for Durability
Select a pump constructed with marine-grade material rated for permanent outdoor installation. Heat and corrosion-resistant outer shells protect internal components from sun, rain, seasonal temperature swings and potential freezing periods if winterizing.
Digital Controls & Programming
Many new high-efficiency pumps come WiFi-enabled for remote operations and scheduling convenience via a smartphone app. Others have programmable touchpads for customized filtration times and auxiliary features. These make pool care stress-free.
Rustproof Propellers & Motors
The continuous chemicals and weather battering the pump endures call for premium metallic and non-corrosive gearing designed to last for the decades the equipment may run. Single speed pumps suffice for basic needs, while 2-speed options flex runtimes based on demand.
Winterizing Capabilities
Consider a winter-rated model if you need to drain and prepare your pool seasonally, with self-priming features that restart easily in spring. Some include thermal protection for extended freeze coverage or live in cold regions.
24/7 Operation Warranty
Given constant year-round usage that compounds stressors, top brands generally warranty pumps 3-5 years for commercial-grade reliability. Others may only rate parts coverage for seasonal or intermittent usage still leaving off-season repair costs uncovered.
Easy Maintenance Access
Look for spacious housing that grants simple basket and impeller cleaning reach without tools. Quality components requiring little upkeep save time and replacement expenses later. Secure latching lids prevent debris intrusion.
Filtration Equipment Match
For optimal flow and performance, pair your pump with matching filter equipment such as sand, DE or cartridge units sized to its ratings rather than mixing incompatible brands. Together they efficiently clean water per turnover periods.
Quality and Price
While initial outlay seems more, reputable pumps built from better materials actually cost less over 15-25+ years by reducing repair/part needs and electricity consumption through higher energy ratings. Consult pool maintenance professionals regarding quality brands.
