Can You Use an Above Ground Pool Pump for an Inground Pool?
The short answer is: maybe, but probably not. While it might seem like a simple swap, using an above-ground pool pump for an inground pool is generally not recommended, and in many cases, it's simply not practical. Several factors determine the suitability, and understanding these factors is crucial before making a decision.
This article delves into the key differences between above-ground and inground pool pumps, explaining why a direct replacement is often unwise and highlighting potential problems you might encounter.
What are the Key Differences Between Above-Ground and Inground Pool Pumps?
The primary differences lie in flow rate (gallons per hour or GPH), horsepower (HP), and head pressure.
-
Flow Rate (GPH): Inground pools are significantly larger than above-ground pools, requiring a much higher flow rate to effectively circulate and filter the water. An above-ground pump's lower GPH might struggle to adequately filter a larger inground pool, leading to poor water clarity and potentially unhealthy conditions.
-
Horsepower (HP): Inground pools often need pumps with higher horsepower to overcome the greater distance and head pressure needed to circulate water throughout the system. A weaker above-ground pump may simply lack the power to move the water effectively.
-
Head Pressure: This refers to the vertical distance the water must be pumped. Inground pools, with their deeper depths and potentially longer plumbing runs, demand significantly higher head pressure. An above-ground pump, designed for lower head pressure, could overheat and fail under the strain of an inground pool's demands.
Will an Above-Ground Pump Be Powerful Enough?
This depends entirely on the size of your inground pool and the pump's specifications. A small inground pool might theoretically be serviced by a powerful above-ground pump, but this is rare. To determine this, you'd need to compare the pump's GPH and head pressure ratings to the recommended specifications for your pool's size and plumbing setup. This information is usually found in the pool's specifications or from a pool professional.
What Happens If I Use an Above-Ground Pump for an Inground Pool?
Using an underpowered pump will likely result in several undesirable outcomes:
-
Poor Water Circulation: The water won't circulate properly, leading to stagnant areas, algae growth, and poor water quality.
-
Overheating and Pump Failure: The pump will likely overheat and burn out due to the increased strain of handling the higher head pressure and volume of water.
-
Insufficient Filtration: The filter won't be able to process the water effectively, leaving debris and contaminants in the pool.
-
Reduced Pool Lifespan: Poor water quality can damage the pool's surfaces and components, shortening its lifespan.
What Size Pump Do I Need for My Inground Pool?
Determining the correct pump size for your inground pool is crucial. It depends on several factors, including:
- Pool Volume: The total amount of water in your pool.
- Plumbing Configuration: The length and diameter of the pipes in your system.
- Desired Turnover Rate: How many times you want to completely circulate the pool's water in a given period (ideally, every 6-8 hours).
Consult a pool professional to accurately assess your needs and select the appropriate pump and filter system for your inground pool. They can perform a proper calculation considering all relevant factors.
Are there any situations where an above-ground pump might work?
While highly unlikely, a very powerful above-ground pump might work for a very small inground pool with minimal plumbing. However, this scenario is extremely rare, and the risk of pump failure is substantial. It’s strongly advised against attempting this without professional consultation.
In conclusion, while technically possible in extremely limited scenarios, using an above-ground pool pump for an inground pool is strongly discouraged due to the high probability of insufficient performance, equipment failure, and compromised water quality. Always prioritize consulting with a pool professional to ensure you have the correct equipment for your specific pool’s needs.
