At Infinity Pool Solutions, we know that pool ownership is about fun, relaxation, and creating memories, not about constantly worrying if your pool water levels are too high or low. That’s where pool autofill systems come into play! Autofills are one of those pool features that don’t always get the attention they deserve, but they make a big difference in keeping your pool in great shape with less hassle. Today, we’re here to explain why having an autofill for your pool is important, how it works, and why it can save you time, water, and money.

What is an Autofill for a Pool?
An autofill is a device that automatically keeps your pool filled to the right water level, so you don’t have to check or refill it by hand. Imagine if you had a little helper that watched your pool’s water level 24/7 and added just the right amount of water whenever it got too low. That’s exactly what an autofill does!
Just like a toilet tank or a fish tank with an automatic water dispenser, a pool autofill system senses when water levels are low and fills it up. It’s a convenient tool that’s usually connected directly to your home’s water line, allowing it to automatically add water as needed.
Why Do Pools Lose Water in the First Place?
Pools lose water for several reasons, and not all of them are preventable. Here are the main reasons why water levels go down in pools:
Evaporation: Just like puddles dry up after rain, pool water evaporates into the air, especially on hot and sunny days. Pools lose about a quarter to a half inch of water per day due to evaporation alone!
Splashing and Play: We all love diving and splashing around, but every splash sends water out of the pool. While it’s fun, it does mean the water level drops over time.
Backwashing: Pools use a filter system to keep the water clean. Occasionally, these filters need to be backwashed, a process that cleans out the filter but uses some pool water to do so.
Leaks: Sometimes, pools can develop tiny leaks, especially in old pipes or pool structures. Even a small leak can cause water loss over time.
With all these factors, it’s easy to see why pool water levels often drop and why an autofill can help you avoid the hassle of constantly checking and refilling!
How Does a Pool Autofill System Work?
A pool autofill is a pretty clever device that’s easy to use. Here’s how it works:
Sensing Low Water Levels: Most pool autofills come with a float valve—kind of like the device in your toilet tank that knows when to stop filling. When the water in the pool gets too low, the float valve senses it.
Adding Water: When the float valve senses low water, it opens a small valve, letting in fresh water from your home’s water supply. This adds water until it reaches the correct level.
Automatic Shutoff: Once the pool reaches the right level, the float valve closes the water supply, stopping the flow. This way, the pool doesn’t overfill.
Most autofills work completely on their own, so you don’t have to turn them on or off. They simply do their job quietly and efficiently, keeping the water level just right!
Why Is Having an Autofill System Important?
Adding an autofill system might seem like a small upgrade, but it’s incredibly helpful. Here are some big reasons why an autofill can make a difference in your pool experience:
Saves Time and Effort: Without an autofill, you’d have to check the water level often and manually add water to the pool when it’s low. This can be inconvenient, especially if you have a busy schedule. An autofill takes care of this for you so you can focus on enjoying your pool!
Prevents Damage to Pool Equipment: Pools need a certain amount of water to keep the pump and filter working correctly. If the water level gets too low, air can get into the pump, which can cause it to overheat or even break down. With an autofill, the water stays at the right level, helping to protect your pool equipment.
Maintains Water Quality: When the water level drops too low, it can throw off the balance of chemicals in the pool. Having a steady water level helps keep the chemicals balanced, which keeps the water clear, clean, and safe for swimming.
Saves Water: You might think adding water to your pool sounds like using more water, but an autofill can actually help you conserve water! By keeping the pool at a stable level, autofills reduce water waste caused by overfilling or topping off the pool when it’s not needed.
Avoids Overflows During Rain: Some autofills have an “overflow” feature to manage heavy rain, helping to keep the pool from overflowing. This is especially useful in areas with frequent rain showers.
Signs You Might Need an Autofill System for Your Pool
How can you tell if adding an autofill system might be a good choice for your pool? Here are a few signs:
You’re Topping Off Your Pool Often: If you find yourself adding water to the pool frequently, an autofill will save you the time and trouble.
Your Pool Has Frequent Evaporation: If you live in a hot or dry climate, your pool may lose more water to evaporation. An autofill can keep up with the water loss so you don’t have to.
You Want to Protect Your Pool Equipment: Protecting your pump and filter is key to a healthy pool, and maintaining the right water level is part of that. An autofill system can help ensure the equipment stays in good shape.

How Do You Maintain a Pool Autofill?
The good news is that pool autofills are very low-maintenance. Here are a few easy tips to keep it working well:
Check the Float Valve: Once in a while, check to make sure the float valve isn’t stuck and is working properly. This part should move up and down as the water level changes.
Inspect for Debris: Sometimes, dirt or leaves can get into the autofill area. Cleaning out any debris ensures the valve can move freely and work well.
Test Regularly: It’s a good idea to test the autofill occasionally to make sure it’s adding water at the correct level and stopping when it should.
Our team can also include a checkup for your autofill system during routine pool maintenance visits, so you don’t have to worry about it.
