Checking your equipment and maintaining your system is best way to solve the small corrective problems.
Start by system by following the path of the water. Clean out the pool’s skimmer basket and emptying the contents of the skimmer basket into your trash can or garbage bag.
Next, open the pump strainer basket and clean it. Check the pressure of the filter. There is no point in checking it before cleaning out the skimmer and strainer baskets, because if they are full the filter pressure will be low and will come back up after cleaning the baskets. If the pressure is high, the filter might need cleaning.
Now check the heater for leaves or debris. Turn the heater on and off a few times to make sure it is operating properly. While the heater is running, turn the pump off. The heater should shut off by itself when the pressure from the pump drops. This is an important safety check.
Now check the time clock for the time of the day ; setting for the daily filter runs; setting for the cleaner’s clock. Always check the clocks because trippers come loose and power fluctuations or some service work on household items unrelated to the pool can also affect the clocks. Also, electromechanical time clocks are not exactly precision instruments. One might run slightly faster than another, so over a few weeks one might show a difference of an hour or more, upsetting your planned timing schedule.
After the equipment check, look for leaks or other early signs of equipment failure. Clean up the equipment area by removing leaves from around the motor vents and heater to prevent fires, and clear deck drains of debris that could prevent water from draining away from the equipment during rain.
