How To Install A Pool Pump Timer: Your Questions Answered

Running the pool pump for 24 hours isn’t wise at all. Installing a timer is extremely necessary. So that you can run the pool between a certain time. 

It’ll ensure a long life for your pool pump. Most importantly, it can save money and energy

How to install a pool pump timer

After preparing your toolbox, you just need to follow a 3 step installation process. It includes fusing the connection. Afterward, you need to get the wiring done. Finally, ground the green wire carefully before restoring the connection. But there are some factors to consider before you start installing.

That was just the tip of the iceberg. We’ve got a lot more here to enlighten you. So, let’s dive deep into it!

Pool Pump Timer: Why Should I Get One?

Getting a pool timer is just as important as removing your backstabbed connections. But why? Well, a pool pump timer can address a lot of your pool-related issues. 

Without a pool pump, ensuring a flawlessly running pool is extremely tough. Alongside ensuring a pleasant circulation of water, it also refrains the pool from running 24/7. Having a timer is really important.

Even during the winter months, the timer can save your pump from being frozen. Only some timers have this feature.

Here’s an important thing to remember. A pump timer is useful in many aspects. But you must understand the specs of your timer. Otherwise, it might accidentally electrify your pool. 

Now we know why you should get a pool pump timer. We should focus on how to install it. But before directly jumping to that part, let’s have an overview of some things:

Things You Shouldn’t Miss Out on Before Buying A Pool Pump Timer

As we already know, a pool pump timer is extremely important for your pool. It’s called the heart of the pool. You must install one as well. But you must have some basic idea about it before starting. 

From cost estimation to energy efficiency, you must know it all. We’ve included all the necessary information here for you. Just go through it carefully to clear out your confusion.

Cost Estimation and Durability

What’s the first thing you consider before furnishing a house? The cost estimation of furnishing your space. The same goes for the pool pump timer too. You must know the cost first. 

Installing a pool pump timer can cost around $750-$1550. Depending on the timer’s durability and features, the price fluctuates. You need to consider the long-run cost of the timer.  

With proper maintenance and care, it can last up to 8 to 15 years. While choosing one, sort your priorities carefully. Take into account its durability and quality for an estimated budget.

Energy Requirements

The energy consumption of a pool pump mostly depends on its size. Moreover, the total time of using the timer has some effects as well. 

Generally, running a 2 hp pool timer for 10 hours a day can cost 720 kWh per month. It draws 2.4 kW per hour. For a 1 hp pool pump timer, it’s 1.75 kW per hour. 

Calculate your energy consumption according to this. But you can save a lot of money by using it during off-peak hours. Running it before 6 am or after 8 pm can save a lot of money and energy. 

Now you’ve got all the necessary information that you need. Now get your pool pump timer and get ready for the installation. 

Installing A Pool Pump Timer: 3 Step Process

After considering all the factors, it’s time for the installation. The process involves a total of 3 steps. But before that, we should start preparing our toolbox. 

Let’s see what should we gather beforehand:

Necessary Tools for Installation 

Firstly and most importantly, you need a pool pump timer. This is the most crucial thing for this project.

Here’s a list of other tools that we’ll need during the installation process:

  • Screwdriver 
  • Duct tape
  • Voltmeter/ Multimeter

Grab all these tools and arrange your toolbox.

Struggling with choosing the right pool pump timer? Here are some suggestions for you. We’ve mentioned all our best picks, so pick one without delay:

Product 1
Product 2

Grab one from this list and wear your handyman cap. Remember to choose one that’s compatible with your pool size and pump. 

It’s time to start the 3 step process:

Step 1 of 3: Turning Off the Circuit Breaker 

Before starting any installation project that involves electricity, turn the main electric supply off. You can even switch the circuit breaker off. Or detaching the fuse from the fuse box also works. 

By the way, as you know it involves water and electricity just like troubleshooting a hot tub. Taking some safety measures is extremely wise. Therefore try to wear gloves and slippers during this project.

After disconnecting the electric supply, we’ll be moving on to the wiring part-

Step 2 of 3: Attaching The Wires To The Terminal  

Just like other electronic gadgets, this pump timer also has two wires – black and white. The black one is called ‘hot and the white one is called ‘load’. 

Now we need to connect the black and white wires to the electrical terminals. Then connect the two wires in terminals 1 and 3. 

You must be wondering which color should be connected to which terminal, right? It doesn’t matter at all. Just make sure these two wires are connected to the two terminals 1 and 3. 

Now it’s time for grounding the wires. Wrap the green wire around the ground terminal. After grounding the green wire, don’t forget to tape the exposed wires. Otherwise, open wires can result in a serious health hazard. 

Use duct tape for wrapping the wires perfectly. It’ll prevent corrosion as well as exposure to the pool water. 

Step 3 of 3: Restoring Electricity and Programming

Now we are all set with the wirings and grounding. Let’s restore the electricity source and check. 

After sealing the timer box with screws, turn the circuit breaker on. Now check if it’s getting proper voltage or not. 

120V or 240V is mostly required by popular timers. Find out your one’s requirements from the manual before checking with the voltmeter.

Do you know how to choose the perfect voltmeter for this purpose? You might lack expertise in this regard to pick the best one. 

Here we’ve suggested some of our favorite voltmeters only for you. You can pick one from here without worrying:

Product 1
Product 2

Problem solved, right? Just pick one from here and start measuring the voltage. 

If your timer is getting the proper voltage, it’s time to finalize the settings. You must set it as such so it runs for 6-12 hours a day.

Make sure it gets at least 5 hours to run without interruptions. Choose a time when most people use it. Only then you can ensure the best swimming ambiance for them. 

Hurray! We are all set with our pool pump timer. 

If your timer isn’t getting enough voltage, either you’ve chosen one that’s faulty. Or there’s been some issue with the wiring. Wrong wiring can be extremely hazardous. It can cause some dangerous shocks.

In that case, contact an electrician to have a look at your timer.


Question: Is it bad to run your pool pump 24 hours a day?
Answer: Running your pool for 24 hours is unrealistic and unnecessary. Running it for 12 hours a day can be a good option. Residential pools should turn over at least once a day. 

Question: How often should you backwash your pool?
Answer: You should backwash your pool once a week. That’s just a general rule. But according to the industry standard, the timing is different. You should wash it when the pressure gauge reads 8-10 PSI. 

Question: Should you cover pool every night?
Answer: It’s actually a good idea to cover your pool every night. It helps to reduce heat loss. So, you can easily swim in the morning even without heating it up or sun heating it. 


With that, we have come to an end. Hopefully, you’ve enjoyed this post.

Now you must have got answers to how to install pool pump timer. So, start your installation mission.
