The short answer
What is the right pool pump schedule for a homeowner? For the most part, it is one that will circulate, filter and sanitize the water without unduly wearing out your equipment or running up the energy bill. But there is no one-size-fits-all solution. The ideal run time is dictated by the volume of the pool, the pump’s flow rate, the state of the filter, the climate and usage patterns.
You can make a good case for running the pump during the day when things are warmest and the pool is in heaviest use. Many find that a single block of time in the daytime, or two shorter sessions to cover morning and afternoon, does the job. As long as the skimmer is doing its work, sanitizer levels hold steady and the water is clear, you are likely on the right track.
What determines run time?
To put a number on how long the pump should be on each day, look at the fundamentals of the system:
- The size and volume of the pool
- Pump type (single-speed versus variable speed) and flow rate
- Filter condition
- Weather and heat
- How many swimmers and how much debris from trees you have to contend with
- Any other gear like heaters, salt systems or automation
A heavily used or large pool will demand more hours than one that is not. With a variable-speed pump you may be able to get better circulation at a lower speed for longer while conserving energy.
When to run the pump
Daytime is usually best since that is when the sun puts a premium on sanitizer and swimmers tend to kick up debris. Hot weather will call for longer run times than the cooler months.
A sensible routine might be to start the pump in the morning for some filtration and skimming, then put it on again in the late afternoon if the pool has been busy. Rather than sticking to the same setting all year, adjust for the season. Some may opt for nighttime operation to take advantage of off-peak rates, but only if it does not come at the expense of water quality. And if you rely on a timer, make sure it is set for the actual conditions of the pool and not merely for convenience.
Is the run time sufficient?
A few days of observation will tell you if the current setup is working.
You may need to add time if you see cloudy water, debris on the pool floor, weak action at the skimmer, or dead spots around the ladders and corners. Fluctuating sanitizer is another indicator.
Conversely, if the pump is making excess noise or heat, or if you are seeing higher energy consumption with no improvement in the water, you are probably running it too long. A clogged basket or dirty filter can also be the cause of very low flow.
Pitfalls to steer clear of
Do not set a run time and forget about it, or ignore the changing seasons. It is easy to fault the pump when what is really needed is a clean filter.
Some basic rules to follow:
- Shut the pump down before you open the skimmer basket.
- Put on gloves and eye protection for any maintenance.
- Heed the chemical labels and the manufacturer’s manual.
- If the water is unsafe, visibility is an issue or you sense an electrical problem, do not swim.
Time to bring in a pro
If the water remains cloudy, the pump cannot hold prime, or you are hearing grinding and humming where there should be none, it is time to call a qualified professional. The same goes for any odd behaviour from your automation, heater or variable-speed pump.
An expert can evaluate the circulation and the condition of the equipment and help you put together a pump schedule that is both efficient and safe.
