The short answer is no. There is really no difference in the amount of energy used at night than during the day.

The most common pump houses a 2 HP motor and uses 0.12 cents per kilowatt hour.

A typical run schedule is 10 hours in the winter and 12 hours in the summer, so you are looking at a little over $2 per day.

It is crucial to run the pump during the hottest, sunniest time of the day so that you are circulating, filtering, and chlorinating when algae is most actively reproducing.

Why This Is Important: It’s important because people who run the pump during the night are leaving stagnant water in the pure sunlight and thus begging for algae.

Backwash while the pool pump is off by following these steps:

  1. Put your multi port valve in the “backwash” position.
  2. Turn the pump on and let it run for 1 minute, or until you don’t see any dirt coming through sight glass anymore.
  3. Turn the pump off.
  4. Put valve in the “rinse” position and let run for 30 seconds.
  5. Now, put the valve back in the “filter” position and turn the pump on.
  6. The final step is adding DE (diatomaceous earth). Ignore this step if you have a sand filter.

Refer to the manufacturers instructions on your filter to find how much DE to add after a backwash.

Why This Is Important: It’s important to keep pressure down on the filter.

The general rule is to backwash when the PSI rises 7-10 points above normal operating pressure (the pressure the filter runs in high speed following a filter clean in pool mode: the filter pressure will always be higher in spa mode. This is called “native” pressure), or every 3-4 weeks.

Some pressure gauges do not register large changes in pressure and some filters need to be backwashed more often.


Why This Is Important: It’s important to keep the pump circulating and filtrating at maximum efficiency. Also, with high PSI over an extended period of time, it can cause damage to the filter and pumps.

Your pool pump can run 6-8 hours in the winter and 10-12 hours in the summer.

Why This Is Important: If the pool is not run for the proper amount of time, it will not filtrate the water through the filter effectively. A pool has a lot of water in it, usually around 10-30k gallons. ALL of that water needs to filtrate, or run, through the filter to clean it. Also if the pool is not circulating and is stagnant, it becomes a breeding pool for algae.

Look at the back of your automatic cleaner and you will find a thruster jet.

Try adjusting that in a different direction than it is already. Point the jet at the wall that the cleaner “hugs” so the water moving through the jet can trust it toward the center of the pool.

Why This Is Important: If the cleaner gets stuck it will not work properly and clean the bottom of the floor or scrub the walls with its tail, thus leaving it moot.


It is mostly due to the water being too cold. The freezing point of water is 32 degrees. Your pool’s “freeze mode” kicks on at 36 degrees. It creates friction in the pipes in order to prevent pipes from bursting and make them less susceptible to cracking.

Why This Is Important: Important to not cause further damage to the other equipment, or to the homeowner, who wants an correctly operating system.

It is highly unlikely that all of your lights will go out at once.

The usual culprit is the GFCI, or ground fault circuit interrupter. This is usually on the side of the main control unit on the pool equipment.

For some reason, something tripped the power going to the lights. Simply do the following to fix it:

  1. Put the system in “service mode.”
  2. Hit the “reset button” on the GFCI.
  3. Turn the lights on via the remote.

Why This Is Important: You can’t see the bottom of the pool at night without the lights and thus may be dangerous for children playing at night.


You can easily tell if your water level is too low if air is being sucked through the skimmers.

Another tell-tale sign is if you can see air or bubbles coming out of the jets.

The correct water level is in the middle of the top tile, near the coping of the deck.

If the water level is too low and the skimmers are sucking air, turn off the pumps immediately and add water to the pool. It does not take very much time at all to ruin the equipment when air is in the system, so be careful to keep an eye on your water level!

Why This Is Important: This is important to keep optimal levels of water to the pumps and thus, avoid burning it up.
