A 15,000-gallon pool needs about 20 GPM output if we want to run it 24 hours per day.

Can you oversize a pool pump?

Dangers of having an Oversized Pool Pump

If your pool pump is too large then you can end up with a number of issues that can be avoided with having the right pool pump size. For Sand Filters, having an oversized pool pump can cause channeling because of the water pressure.

How many gallons per minute does a 1.5 HP pool pump?

For each 1.5 inch intake line, the maximum flow into the pump will be 42 gallons per minute (GPM).

Is 1 HP pool pump enough?

Let’s start with an unpopular and incredible statement: A typical size residential pool can be circulated effectively with a 1 HP pump.

Is a bigger pool pump better?

A pool pump that is larger than needed has a more powerful motor and circulates water at a higher flow rate. This uses significantly more energy to pump the same amount of water and puts additional stress on your pipes and filter, meaning you’ll need to replace them sooner.

What size pump do I need for a 27 foot above ground pool?

For round above ground pools up to 24 ft. ( pools with less than 15,300 gallons) use a 1 HP pump. For round above ground pools over 24 ft. (pools with more than 15.300 gallons) use a 1.5 HP pump.

What size pool pump do I need for an 18 foot above ground pool?

For pools up to 24 Ft Round, use a 1 HP pool pump. For pools over 24 Ft Round, we recommend using a 1.5 HP pool pump.

How many gallons per minute does a 1 HP pool pump?

You can see from the chart that a 1 horsepower pump will give you 52 gallons per minute on a system with 64 feet of head. We want to give you the flow information on each pump so that you can come up with the right pump the first time.

Can my pool pump be too powerful?

The more powerful your pool pump is—the more horsepower it has—the faster it will turn the water over, which means you can run it less often and for shorter periods of time. But this is also dependent upon the size of your filter and the filtration system’s pipes. A too-powerful pump can be too much for a small filter.

Is a higher HP pool pump better?

Many 2hp pumps have been installed when a 1hp pump could deliver the same flow volume, with greatly reduced energy usage. Larger pumps not only produce larger electrical bills, but having an over-sized pool pump can lead to poor filtration when matched with smaller pool filters.

Is a 2 speed pool pump worth it?

At River Pools, we used two speed pumps for years with great success. They are quite a bit more expensive to purchase than single speed pumps and last the same amount of time, which is typically 3-8 years. On average, a two-speed pump will save about 50%-70% on energy cost compared to a one-speed pump.

How much HP pump do I need?

Horsepower theoretically required for pumping water equals the gallons per minute multiplied by the head in feet, and divided by 4.000 For power recommended, divide by 2000 instead of 4000.

How many gallons per minute does a 2 HP pool pump?

The maximum flow into the pump will be 73 gallons per minute for each intake line. The maximum flow into the pump is 42 gallons per minute for each 1.5 inch intake line.

What is the difference between 1 HP and 1.5 HP pool pump?

As I mentioned before, the 1.5 HP PowerFlo LX has only 1 GPM more flow rate than the 1 HP PowerFlo LX so very little difference between the two pumps. However, for an 18″ filter, you don’t want to exceed more than about 35 GPM.
