How to Fill a Swimming Pool with Well Water?

Many people having a swimming pool and water well at their properties wonder whether they can fill their pool with well water. If you are building a new pool at your home or buying a home with a pool and a well and have the same question in your mind, you are in the right place.

In this article, we will discuss how to fill a swimming pool with well water and what things you need to consider while filling it in. This article will serve as a complete guide for filling a swimming pool with well water.

How to Fill a Pool with Well Water?

Filling a pool with the well water is no rocket science. If you have a submersible pump, it will be easy to fill the pool. You can also use a pool pump but filling a pool will put a lot of pressure on it. A pool pump is used to push water in the pool through the filtration system and not from the well. You would need to do the following.

  • Connect one end of a hose to the well pump and put the other end in the pool.
  • Turn the pump on and observe the process.
  • Do not leave the pool when water is flowing as you need to make sure that water does not go brown.
  • Turn the water off if you notice any color change, wait for a couple of hours, and then start filling the pool again.

Factors to Consider While filling the Pool with Well Water

The following are the important factors to consider while filling a swimming pool with well water.

Swimming pool dimensions

Pool Size – The size of your pool will impact the time taken to fill the pool. It will also tell you the amount of water you need to fill in the pool completely. The size of the pool is also linked with water availability. Suppose that your pool’s capacity is 7500 gallons and the maximum flow rate you can get from your well water is 500 gallons in an hour. It will take around 15 hours to fill the pool completely. However, it is not that simple. You need to take into account some other factors as well. You can calculate the volume of water needed for your pool using an online tool or formulas.

Underground Water Volume – The volume of water in your well will also impact the pool filling time. If there is less water, it is possible that your well will be empty in no time, and you will have to wait for 12-24 hours for the well to replenish. The replenishing time depends upon the water table in the area. Environmental factors like drought, less rainfall, weather conditions also impact the filling time. The best way to avoid this is to fill your pool in intervals. Let’s suppose that your pool takes 10 hours to fill up. You must run water for two hours and wait for two hours so that water again fills up in the well. In this way, your well will not dry up, and you will not face the no-water-in-the-well problem, and your neighbors will also get adequate water. This technique will also avoid sediment getting into your pool, and you will get crystal clear water.

Water Delivery Rate – This factor is also related to the volume of water in your well. If it has a higher volume, you would be able to fill the pool in less time as compared to a well with less water.

Health of Well Equipment – It is very important to consider the health of the well equipment like well pump, pipes and hoses. Filling a pool requires vigorous working by your well pump. If your well pump is not in a mint working condition, it may stop functioning. Now you will have a bigger problem on your hands. Make sure that your well pump is working efficiently before you start filling your pool.

Water Demand and Supply – When you plan to fill your pool with well water, make sure that it is not being used for other purposes for a day or two before filling day. Avoid watering your garden, fields, washing your vehicles and clothes, and doing any other activity which will put a strain on your well and reduce the volume of water underneath.

Testing your Water – EPA suggests that very well owners must get their water tested every year. A yearly test will tell you about the percentage of heavy metals, microorganisms, calcium, magnesium, arsenic, and other harmful contaminants. You must make sure that these elements are under the safe limits prescribed by the EPA. You should also check for water hardness levels and ensure that they are in the soft water range. Hard water can make your skin dry and lead to dandruff, rashes, and allergies. You must also look for the pH of well water and try to bring it near 7. To get rid of the contaminants, you can use a water softener to remove calcium, magnesium, and iron from the water. To make the pH neutral, pH drops are the best solution. You will have to calculate the number of drops needed to bring the pH to 7 according to the volume of water in your pool. If your water is basic, you would need acidic pH drops, and for acidic water, basic pH drops would be required. Most of the drops come with instructions on how much to add and how to add. However, it would be best to consult pool professionals or search for it online. You can also use muriatic acid to decrease pH or soda ash to increase it. If you find high levels of hydrogen sulfide in your well water, you are likely to expertise a rotten egg smell in your swimming pool.

Treating the Pool Water – If your well has a high concentration of iron and manganese, it is likely to go brown after filling up. Brown water is an ugly sight in the swimming pools. You can use a sequestering (chelating) agent in your pool to dissolve iron and other metals. Once they are dissolved, you would have to vacuum the pool to remove the rust from it. To get rid of microorganisms, chlorine is used as a disinfectant. The chlorine will evaporate naturally with the sunshine over the course of 3-4 days, or you can also use ready-made chlorine neutralizing products. To clean sediments, a pool filter is used.

Pool Water Delivery Service – You can also use pool water delivery services. You have to pay for water and get your pool filled. If you are opting for it, you don’t need to worry about water quality as the water these people provide is already treated and free from contaminants. You also don’t need to worry about setting up the water hose, water delivery rate, water table, well pump, and water testing. It is an easy way out, but it will cost you a lot.

Tips to Avoid Water Loss from Swimming Pools

Either you use well water, city water, or a water delivery service, preventing the water from evaporating from your swimming pools is equally important. You can take the following actions to stop water loss from the pools.

Fix the Leaks – You must check for leaks in your swimming pool’s plumbing system after 5-6 months. A small leak can waste thousands of gallons yearly. Get the leaks fixed urgently.

Solar Covers – Solar pool covers are used to stop water evaporating from the pools. They cover the surface of the water and also prevent the water temperature from getting extremely high in summers.

Avoid Frequent Splashing – Splashing and playing with water is fun. However, doing such things frequently result in loss of water from pools.

Final Words

Swimming in your pools is a great way to relax and cool down. Everyone loves to swim and have some fun. However, you must make sure that the water in your pool is healthy and does not affect your health.
