What are the different types of pool filters?
Filters. There are three types of pool filters (sand, cartridge, and DE) and all of them have different maximum flow rates based on their surface area. Make sure you stay below the maximum flow rates for your filter system or you could end up damaging it. Here are the flow rates for common filter types and sizes.
What is a total dynamic head?
Total dynamic head is a resistance metric – it tells you the total amount of resistance in the hydraulic system of your pool. The filter, pump, pipes, heater, backwash valve, return, and other accessories have an effect on how water flows throughout your system. Most inground pools will be somewhere around 50 TDH. Above ground pools typically fall around 30 TDH. We’ll go into more specifics on TDH in another post.

What is lift in a well pump?
It is the "lift" that overcomes the head pressure of water in the piping system above the pump.
How is the capacity of a centrifugal pump determined?
Capacity is determined by the exit width of the impeller. All of these factors affect the horsepower size of the motor to be used; the more water to be pumped or pressure to be developed, the more energy is needed. A centrifugal pump is not positive acting. As the depth to water increases, it pumps less and less water.
How many horsepower is a pool pump?
Water pumps of 1, 1.5, and 2 horsepower are very common -- and for the average size pool, very oversized. Oversizing pumps have become such an issue that the State of California (a big pool state), recently enacted a law to control how big of a pump could be placed in a swimming pool.
