The 12 Best Pool Timers

The best pool timers allow you to keep your swimming pool spotless without needing to run your pump around the clock.

Keeping a pool operational is expensive enough anyway, so every saving you can make helps.

Beyond the savings you’ll make on reduced running costs, you’ll also prolong the lifespan of your pump.

Pool timers are, in effect, a bridge between your pool pump and the electrical outlet. By setting the timer to kick in at set times each day, you’ll ensure that power to the pump is severed on demand and reconnecting when it’s programmed to kick in again.

So, by investing in one of these simple but effective devices, you’ll be keeping your pool water perfectly clean while slashing running costs and the cost of replacement pool equipment.

While a timer is on the surface a very simple device, there are nevertheless several pointers worth considering when you’re on the buying trail. Focus on the following to streamline your decision:

• Mechanical or digital: Mechanical timers are simple to install, easy to use, and capable of returning years of faithful service. Digital timers offer more precision and more programmability, but you’ll need to dig deeper for the privilege
• Load capacity: This rating expresses how much load the timer can handle. The best pool timers are flexible enough to cope with variable loads. If you’re planning to run more than one pool pump, you can find timers capable of this, and we review several of them today. Most pool timers have standalone three-way circuits that can be programmed to work independently.
• Current rating: You’ll need to know how much current the pool timers on your shortlist can cope with. You’ll have to consider the size of the pool and whether it’s in a residential or commercial setting. You’ll need a timer that’s rated higher for current than your pool pump. Get this right and you won’t need to worry about your timer ending up as the weak point in your pool system
• Safety: Make sure any timers on your shortlist intended for outdoor use have water-resistant and dust-proof housings. Connections should be fully insulated. Not all pool timers are designed for use outdoors. If you’re planning to use yours outside, make certain you buy one that’s suited to this purpose
• Programmability: The best pool timers allow you to program in on/off operations for set times each day. You should also look for memory save settings that won’t leave you whistling in the event of a power outage

OK, with those basics taken into account, you should have everything you need to compare the best pool timers and find the most appropriate one for your needs.

Let’s get right down to business now with our top 12 pool timer reviews so you can accurately assess what’s at your disposal.

How Does a Pool Timer Work?

A pool timer is designed to work in tandem with one or more pool pumps. You can program the timer so that the pump will stop running during periods when the pool is unoccupied. It doesn’t make sense to run all your pool equipment around the clock, and it becomes extremely expensive doing so.

You simply connect your pool timer to a grounded power source and then wire it to your pool pump.

A pool timer is an electrical timer with mechanical components, so you’ll first need to ensure the time setting is correct so you can then create accurate start and stop times based on this.

With a manual timer, you’ll rotate it clockwise or counterclockwise so that the current time lines up with the Time marker. This marker will always point downwards, while the dial of the clock will always be turning.

The physical components that activate and deactivate your pool pump on demand are called trippers.

Set the On tripper for the times that best suit you by holding the tripper to the Off time on the dial you need then tighten it down with your screwdriver. As soon as the On tripper gets to the current time marker, electricity is sent to the pool pump the timer is hooked up to, and the pump activates. The pump will then run until the Off tripper is reached. At this point, another burst of electricity is sent from the timer to the pump. The pump will stop running.

Most of the best pool timers allow for manual override if desired. This lets you turn the pump on and off without needing to touch it. It will run until you flip the On/Off switch to Off. Since the trippers will still be in place, the unit will press ahead with all schedule activity.

If you experience a power outage, the timer will be switched off and the clock dial prevented from turning. You’ll need to reset this. You won’t need to make any adjustments to the trippers as they will remain in place and unmolested.

OK, before we round out today, we understand that pool timers are perhaps not totally self-explanatory. To help you, we’ve curated a list of the most frequently asked questions about pool pumps and pool timers so you have everything you need in one place.

FAQs

1) How long should I run my pool filter for each day?

Most guidelines suggest running your filter for 8 hours daily across either 2 or 3 cycles. To establish the precise recommended running time, multiply the GPM rating of your pump by 60, then divide the capacity of your pool in gallons by this number. Sticking to the industry standard 8 hours is a safe bet, and saves you from any tedious mental math.

2) Is it harmful to run my pool pump continuously?

It’s not harmful, but two things will happen if you run your pump 24/7. Firstly, your electricity bills will be high. Beyond this, you’ll shorten the lifespan of your pool pump by running it for three times the suggested duration on an ongoing basis.

3) How much money can I expect to save by using a pool pump timer?

This will depend to a large extent on how you have been running your pool pump until that point. If you had been making the costly mistake of running the pump around the clock, using a timer to regulate operating hours could easily save you $500 annually. If, on the other hand, you’ve been using a lighter touch with your pool pump, you won’t notice such pronounced savings.

4) Is there a difference between pool timers for in-ground pools and above-ground pools?

Yes. Above-ground pools work best with timers suitable for 1.5 HP pumps. If you have an in-ground pool, look for timers supporting pumps rated to 3 HP.

5) Is it possible to control other loads with a pool timer?

Yes, with many of the models we review today you can control landscape lighting, heaters, AC units, and other similar appliances. As with all aspects of your buying decision, you should ensure you buy in line with your needs and the requirements of your pool area.

6) What are smart pool timers?

These timers allow you to connect the timer to compatible devices then take charge hands-free in-app. These devices communicate using protocols like Z-Wave or Zigbee, and you can integrate a timer like this with your smart home. Most of these timers also allow you to control them like you would a regular timer.

7) Is it better to run my swimming pool pump during the day or overnight?

Generally, you should run your pump during the day to help circulate the chlorine. Sometimes, in the event of an algae outbreak for instance, you may also want to run your pump overnight.

8) Is it difficult to program a pool timer?

All models are different in terms of operation, but most are pretty easy to use. We draw your attention to any issues in this area in our reviews today.

9) How does a pool timer actually work?

Think of your pool timer as a middleman between the pump and the power outlet. By mediating this connection, you’ll remain in control of when your pool pump operates without needing to physically turn it on and off.

10) My pool timer doesn’t seem to be working properly. How can I troubleshoot this?

The first thing you should do is check the electricity supply running to your timer. If you have an automatic timer, you should make sure the LCD is displaying the right time. If you have a dial timer, you should check the position of the dial, the on pin, and the off pin. Check again after a few hours. If there is no movement, your timer is not working, or the electricity supply is off. Next, check the circuit breaker that operates your timer. This should be in the on position. Ensure that the manual override  switch is on. This is typically located underneath the dial. If the electricity has been off, you should reset the swimming pool clock.

11) Do I really need a pool timer?

Well, as you can see from today’s guide, you won’t need to spend too much on a pool timer. Even the most innovative smart models are still very keenly priced, especially when set against the cost of more major pool equipment. In return for these nominal investment, the first and most obvious saving you’ll make is on running costs. As mentioned above, this could amount to saving $500 or more each year if you had been running your pool pump indiscriminately. Also, there’s every chance your pool pump is quite expensive. If you needlessly run this around the clock, you’ll end up dramatically decreasing the lifespan of your pump. To get around this, you would need to constantly remember to turn the pump on and off, something that rapidly becomes tedious. Instead, for a very reasonable price, you can get yourself a pool timer and forget all about this.

12) Are all pool timers easy to install?

Most of them are. What you’re getting is a very simple plug-and-play device, so in most cases you’ll just need to plug the timer into the outlet and you’re good to go.
