How Long Does It Take to Fill a Pool with a Garden Hose?

It’s a sunny day and you have been dying to go swimming. You run outside, turn on the hose, and get to work filling up your pool. How long does it take? It depends on the size of both the pool and the hose. But what if we don’t know either one? In this article, we’ll explore how to calculate how much time it will take for this task. We’ll also give you an equation that will help you find out!

Can you fill a pool with a garden hose?

The first question that needs to be addressed is whether or not a garden hose can fill a pool. There are two important factors that need to be considered in order to answer this question: the size of the pool and how long it takes for water from a garden hose to drain into an empty swimming pool.

The diameter, length, and width of pools vary greatly from model to model depending on their intended use (e.g., backyard family pools vs professional competition pools). In general, though, most residential-sized above-ground models range between 15′ x 30′ up to 20′ x 40′. The depth of these types of pools also varies based on design but usually ranges between three feet deep at its shallow end all the way down six feet deep at its deepest point.

Can you fill a pool with a garden hose?

With this in mind, it is possible to fill a pool with a garden hose if the diameter of the pool is small enough such that the water from the hose gradually fills up all sides at relatively equal rates. However, when dealing with larger pools or ones which have greater depths then using a garden hose becomes impractical and inefficient for filling them completely especially since most standard hoses are limited to about 50 gallons per minute (GPM). This means that even though you can technically use a garden hose to fill your pool slowly over time, it would take several hours before any more than an inch has accumulated on the decking around its perimeter. In fact, some smaller models might not be able fully to fill from their own weight alone depending on how fast or slow the water is being supplied from a garden hose.

On the other hand, if you have an extra-large pool and there are no obstacles in its path such as trees which could obstruct a steady flow of water then it might be possible to just use a regular old garden hose for filling purposes.

Water Pressure and How it Affects Filling Speed

One important factor of the filling process is the water pressure. Lower water pressure will result in a long time to fill but may be more suitable for some people depending on their situation.

Water Pressure and How it Affects Filling Speed

In order to accurately calculate how long it takes to fill your pool with a garden hose, you must determine what type of faucet provides access to that source of water.

If you live in a single-family home, there is probably only one faucet that provides access to the waterline. This also usually means that your hose can reach all areas of your yard and if not then it will at least be relatively close by (provided that you do not have an above-ground pool).

However, if you are like most people living in apartments or condos, they may only provide access to either a showerhead inside your residence or possibly community amenities such as an outside watering station for plants. These types of sources would take much longer than filling directly from household plumbing because they lack pressure; therefore it is important to specify this type of information when asking someone how long does it take to fill with a garden hose.

How to Determine the Water Pressure of Your Hose

There are a few simple steps that can be taken in order to determine the water pressure of your hose.

How to Determine the Water Pressure of Your Hose

The first step is to attach the garden hose nozzle and turn on the faucet, but do not open it completely because this will force too much water through at one time which may cause damage to both your plumbing and home (not recommended).

Afterward, adjust the flow control valve until you reach an optimal speed for filling; then measure how long it takes to fill up a bathtub or other container with known measurements like gallons or liters. If necessary make adjustments by either opening up more on the valve if your container fills too quickly or lessening it if needed so that it has just enough strength in which you feel comfortable using.

If you happen to have a pressure gauge, this would be a great tool in order to establish your water flow rate in pounds per square inch (PSI) so that the information can be used in calculating how long it takes to fill up a garden hose.

In most cases when using just the nozzle on your watering device, PSI is around 40-60 which will determine its ability to move larger volumes of water at once.

How to Determine the Water Pressure of Your Hose

This number varies depending on several factors given previously mentioned such as household plumbing and overall length of hose; however, for home use filling small pools or containers should not take more than an hour even if there are low pressures involved.

Filling Speeds of Different Common Sized Pools

Now let’s assume that you are filling pools of different sizes. For reference, the average American swimming pool is between 16-20 feet long but can be as small as 52 inches in diameter (yes, I know what you’re thinking…). When it comes to figuring out how fast your water pressure will fill a pool, consider this simple equation:

The larger the hose and nozzle size = The faster the rate of flow.

So now let’s say we want to figure out how long it would take for us to fill our 20 foot by 40-foot in-ground vinyl lined pool if we were using an unregulated garden hose with no sprayer attached at 25 psi? Here goes nothing!

Filling Speeds of Different Common Sized Pools

We need to first convert the length into feet. We have twenty feet in our pool, so we will multiply 20 by 12 to get the total length of 240 feet. We are going to assume that there are no obstacles or restrictions where you want your hose placed (like a yard), but if there is something obstructing it, make sure to take this into consideration! It’s time for another simple equation:

Length of hose, divided by the flow rate (in gallons per minute) = Number of minutes required to fill.

Now that we’ve determined our length is 240 feet and our water pressure at 28 psi, let’s divide the number like so: 240/28= approximately eight minutes it would take for us to completely fill up this pool with a garden hose! Not too shabby right? But what if I told you there was an even faster way?!

Since most people are limited on time or patience when filling their pools via standard hoses connected to your hose spigot, one option might be investing in something called a booster pump. A booster pump will help increase your overall water pressure coming into your home which can consequently speed up the process of filling your pool significantly.

How Much Does It Cost to Fill a Pool with Water?

The next worrying question is how much does it cost to fill a pool with water?

You may be surprised to find that even filling your own pool is not cheap. You can expect the price of filling up a small backyard swimming pool (or spa) will set you back about $100 – and this doesn’t include any additional costs such as electricity or labor fees if you’re paying someone to fill it for you.

If the pool is large or public, then this price can jump up dramatically.

The average price of filling up an above-ground swimming pool is about $60 for every thousand gallons needed. This can fluctuate based on where you live and other circumstances such as the distance required to transport the water or whether there are any additional fees associated with pumping out your septic system before filling the pool.

How Much Does It Cost to Fill a Pool with Water?

It’s best to get multiple quotes before committing if this will be something done by yourself without professional assistance because prices range widely throughout different areas in America. If having your local company fill your pool sounds appealing then expect to pay around one hundred dollars or more per hour that they work plus whatever fuel charge they charge.

How to Fill a Pool Without a Hose

There are a few ways to get around using your garden hose to fill the pool.

  • Use a bucket

You can use a large plastic container or two five-gallon buckets and have someone hold them as you pour water into it from above. You will either need to go up on the ladder or raise one of those containers with some sort of rope/pulley system.

  • Fill with a fire hose

If you have access to one of these, they are very strong and can accommodate large amounts of water quickly. Using this method won’t cost any money (if it’s your fire department) but will probably take some time if there is no one else around to help out. You could also call the local pool store or newspaper and ask them for someone who would be willing to donate their time/services in exchange for advertising & mention on social media etc…

How to Fill a Pool Without a Hose

  • Use a submersible pump

This option costs the most initially ($100+) however it doesn’t require anyone to hold anything as well as stores inside so that it is ready when next year! The only downside is that it doesn’t work too well with very large pools.

  • Use a pool cover pump

This option also costs money ($100+) and is only really worth the investment if you have a larger than average size pool to fill (15,000 gallons or more). This method will require someone else to hold something as well but works without electricity so no need for extension cords either! The advantage of this system is that because your not filling from above like in other methods there’s little chance for debris such as leaves falling into your new clean water. It does however require extra storage space both inside & out.

How to Fill a Pool Without a Hose

  • Well Water

This method is free, however, it will require effort on your part to make sure the water quality is acceptable (chlorine levels, etc). The downside of this option is that if you do not already have well water & live in an area where there are wells available for public use, chances are they aren’t too close.

  • Rainwater

Another way to avoid using tap water for filling would be rain barrels. These can be bought relatively cheaply and work very similar to a submersible pump except with no electricity required! You could either hook up multiple rain barrels or buy one large enough to accommodate all the pool’s volume without having someone hold anything while you fill it which makes things much easier/quicker overall.

How long does it take to fill a 5000-gallon pool with a garden hose?

It takes about 45 minutes to fill a 5000-gallon pool with a garden hose. This calculation is based on using 30 psi of water pressure, filling the pool at 11 gallons per minute (GPM), and having an average flow rate of .0029 cubic meters per second.

Will 2 hoses fill a pool faster than 1?

Yes. If you have two hoses hooked up to the spigot, it will fill your pool faster than if only one hose is running into the pool. When using two hoses, each hose should be receiving around 11 GPM (gallons per minute).

Can I fill my pool overnight?

Yes, you can fill your pool overnight. However, if the ambient temperature is above 85 degrees F, then it’s recommended that you drain and refill your pool every 12 hours to avoid algae growth in the pool.

Final Thoughts

Now that you know how long it takes to fill a pool with different scenarios, it’s time for you to weigh out all of your options and decide what is best for your specific needs!

Remember though; if you are living in an area where there isn’t much water pressure at the source (which can be common), or this just happens to be something on your bucket list so-to-speak, investing in one might not hurt either. Since they don’t require any additional electrical work but simply hook up between two hoses that come directly from the well/pump system located underneath ground level.

We hope that this article has given you a little more insight into how long it takes to fill a pool with different setups, and now you are able to make an educated decision on whether or not buying one of these would be beneficial for your family.
