How many times per day should pool water turn over?
A Rule of Thumb This is based on the assumption that your average pool pump has a turnover rate of about 8 to 12-hours. That means that the total volume of your pool water will filter through your system 2 to 3 times per 24-hour period. For a residential pool the water should turn over at least once per day.
How do you calculate turnover rate in a pool?
Formula for Turnover Rate: Divide the pool shape into areas of constant depth, or constant slopes. Turnover Rate(TR) = Gallons divided by Flow Rate (FR) divided by 60. Flow Rate (FR) is measured by a flow meter.

Turnover Rate is the time (in hours) it takes your circulation system to move the number of gallons equal to the total volume of your pool. Flow Rate is the speed of water running through your pipes measured in GPM (gallons per minute).
How long can you run a pool pump on recirculate?
As a thumb rule, 2 hours of running the pool filter on Recirculate is enough. This is enough time for a pool chemical such as Cal Hypo or Floc to be evenly distributed throughout the pool. However, there is no limit on how long you can or should run the pool filter on the “Recirculate” mode.

You find the right flow rate for your pool by calculating its capacity in gallons. Then, divide that number by your desired turnover rate, ideally six to eight hours. Divide that answer by 60 to find the minimum gallons per minute, or GPM, flow rate required to achieve the desired turnover rate.
Why use variable speed pool pumps?
In addition, variable-speed pumps have more efficient motors than traditional pumps and can be set to the exact speed your pool requires, potentially saving a significant amount in power costs.
Why Should Your Pool Have Good Circulation?
Circulation moves your pool water through the filter, removing particles and debris from the pool. This is important because, without proper filtration, impurities can build up resulting in a dirty pool. Proper filtration will not only mean fewer required chemicals to disinfect the pool water but it also means that swimmers can experience water with less irritation and chemical smell.
Why is circulation important in a pool?
Proper pool circulation is one of the keys to maintaining a healthy pool environment. Circulation helps your pool sanitation system, filter and chemical additives all function properly. Without the right circulation, your pool can encounter a number of problems.
What is the purpose of circulating a pool?
Disinfection. Circulating your pool disperses any disinfectants in the pool, allowing them to sanitize all of your pool water. Without proper circulation, any chemicals you add will not be evenly distributed throughout the pool water and any additional sanitation system will not be able to disinfect your entire pool.

Any doors with direct pool access should have an audible alarm that sounds for 30 seconds. The alarm control must be a minimum of 54 inches high and reset automatically.
Why do you need a cover for a pool?
Winterizing the pool also can be hazardous. The pool water in most belowground pools is seldom drained because of groundwater pressure that can damage the structure of the pool. Therefore, water in most home pools is only lowered below the frost line for winter protection. In these cases, a pool cover is installed to keep debris and leaves from filling the pool in the winter months. The pool cover becomes an excellent mosquito-breeding area before the pool is reopened in the spring because of the decomposing vegetation that is on the pool cover, the rain that accumulates on the top of the pool cover during the winter, and the eggs laid on the pool cover in early fall and early spring. The cover also provides ideal conditions for mosquitoes to breed: stagnant water, protection from wind that can sink floating eggs, the near absence of predators, and warm water created by the pool cover collecting heat just below the surface ( Figure 14.1).
Why should you keep tables away from the pool?
Tables, chairs, and other objects should be placed well away from the pool fence to prevent children from using them to climb into the pool area.
