Frequently Asked Questions
Q:How much does it cost to build a pool?
A: This is one of the most frequent questions we’re asked. Unfortunately, there is no easy way to answer questions related to the cost of building an in ground swimming pool. Shopping for a pool is much like shopping for a new car. There are so many options and features available that it is nearly impossible to determine the cost of a new swimming pool until selecting a design and all the features that will be included.
Factors that affect pool cost:
- Size: costs based on pool perimeter
- Depth: Play Pool vs. Diver
- Materials: Plaster, Coping, Decking
- Additional Features: Equipment, Water Features, Waterfalls, Diving Boards, Slides
- Slope of Yard
In the Dallas area, to build an in ground swimming pool the cost generally starts in the 45K range for a swimming pool only, and to build a pool and spa the base price jumps up to 55K. From there, selections such as tile, plaster and the materials used for decking can increase the cost of your new in ground pool.
How big is the new swimming pool of your dreams? It goes without saying, the larger the swimming pool the more materials that will be required. Therefore, the larger the pool the greater the cost to the customer will be. The same goes for the depth of the pool. If you’re looking for a backyard diving pool the cost will be much greater than the cost of your average depth play pool.
New pool materials options are endless – the basic white plaster is much more cost effective when building a new pool than some of the colored options. From there you can chose from different pebble options or polished plasters. A top of the line plaster finish can easily add 8-10K to your new pool build price. Is the pool decking a standard concrete deck, or a hand laid travertine? How large is the pool deck? There are so many different finish options for every aspect when it comes to materials that a customer could easily double the base price of a pool with upgraded selections.
When you build a new pool, cost can also increase depending on the equipment and pool control system. A basic time clock is the “entry level”, but most customers chose to automate their pool system and have the ability to control the pool from a either a handheld or wall mounted controller. Newer pool control systems also give customers the capability of controlling their swimming pool from any smartphone or computer, even remotely. These systems can easily add several thousand dollars to the cost of a new pool.
Is the pool a basic lounge pool, or does it have water features and waterfalls? These added features require additional materials and plumbing, and additional equipment to run the features.
Q: What is the difference between chlorine and saltwater sanitation, and which is better?
A: The topic of chlorine vs. saltwater sanitation has always been a controversial and widely debated topic across the pool industry. Which is better? Ultimately, this comes down to a matter of preference. Don’t let the phrase “saltwater” mislead you – saltwater pools use electrolysis to generate a natural form of chlorine to sanitize the water in your pool. So, is saltwater better than chlorine? We’ll cover the facts and let you be the judge.
One major benefit of having a saltwater pool is that it uses modern technology to naturally generate chlorine. With a salt system, so long as the salt level in the pool is kept in the ideal range, the system will naturally generate chlorine to sanitize the water. This creates a steady stream of chlorine into the pool water all the time, helping to eliminate the excessive chlorine usage or waste.
With a chlorine pool, the pool must be sanitized on a regular and frequent basis to kill bacteria in the pool and prevent algae. This means regular and frequent testing of the water chemistry to determine the current level of chlorine, and some basic math to determine how much chlorine to add. Often times we find that the average consumer uses much more chlorine than is actually necessary.
Hands down, the initial investment of a salt system is much more expensive than the cost of a chlorine pool. An average salt system will cost a consumer between $1500 and $2500. To add an inline chlorinator to a swimming pool should cost roughly $150. From there are the concerns of periodic maintenance. The salt cell should be cleaned every 3 months, or 500 hours of run time. It’s a pretty simple process, however cleaning the salt cell requires the use of muriatic acid. To pay a company for this routine maintenance will typically cost between $50 and $100.00. There is no periodic maintenance required for a chlorine pool in regards to the chlorination process.
With a saltwater system, like any electronics, there will be parts that fail over time. The average life expectancy for a salt cell is 5 years. Sometimes we’ll see a shorter life, but rarely does a consumer get more than 5 years out of the cell. To replace the salt cell generally runs between $750 and $1000. The cell isn’t the only electronic component of the salt system. There’s also the power center/control board which is the brains of the system. A replacement control board can cost as much to replace as the salt cell and sometimes even more. The last main component of the salt system is the flow sensor. This sensor acts as an on/off switch for the system, so that it doesn’t try to generate chlorine without water flow through the cell. We frequently replace these sensors due to damage to the cord either from landscape crews, or rodents who like to chew on them. A replacement flow switch typically runs $250 – $350.
The greatest downfall of a saltwater system is the fact that salt is highly corrosive. Homes with saltwater pools in the backyard will notice calcium buildup on the windows, and rusting of any metal furniture. It can also result in damage to the pool’s equipment. Saltwater is so corrosive it will even result in corrosion of any concrete, natural stone, or travertine around the pool.
Q: How Long Should I Run My Cleaner?
A: This is a very common question we receive, especially from new pool owners. The answer – It depends on the pool, and on the type of cleaner in your pool.
Two Main Types of Cleaners:
There are two main types of pool cleaners as far as functionality is concerned. The most common and functional type is a pressure based cleaner. These cleaners utilize a booster pump to supply water pressure to the cleaner, and the venturi principle allows the cleaner to pick up debris into an attached bag. With a pressure based cleaner the pump can be set to run a specified time each day. On average, a pressure cleaner takes 3-4 hours to cover the entire floor of the pool.
The second type of cleaner is a suction based cleaner, where the movement of the cleaner is created by suction of water through the pump. On a suction side cleaner, the user cannot regulate the amount of time the cleaner can run, as it will run anytime the pool pump is running.
Pressure Cleaner Run Time:
Back to the initial question at hand, how long should your cleaner run each day? We already know that the cleaner can cover the entire pool in 3-4 hours. This is typically plenty of run time, aside from during the fall season. If the backyard contains lots of vegetation that will shed during the fall, it may be ideal to run the cleaner longer each day. In this scenario, the cleaner bag may fill up faster than the leaves are falling in the pool. During this peak workload, it is ideal to empty the cleaner daily, and from there you can trial and error the run time to make sure the pool floor stays debris free.
Q: Why does my spa drain at night?
A: If you’ve noticed that your elevated spa is draining down to the level of the pool while the pool equipment is not running, you’re experiencing the classic signs and symptoms of a bad check valve. A check valve, also known as a one-way valve, is designed to prevent gravity from forcing the water in your spa back through the system and into the pool. If you experience the spa draining at night or while the equipment is not running you likely have debris stopping the spring loaded flap from closing properly OR the seal on the flapper valve has been compromised.
While the pool pump is running the symptoms of a bad check valve are masked because the pool pump is forcing water through the plumbing and into the spa. Typically the spa has a spillway back down to the pool, allowing for proper water circulation. When the pump shuts off, if the check valve has failed it will allow the water to drain back into the pool. From there all the excess water in the pool will run out the overflow drain (if equipped).
There are many different types of check valves, but they all operate on the same basic principles. While the pump is running there is enough water pressure that the spring loaded valve is forced open, allowing the water to flow through the valve. Then, once the pressure from the pump stops, the valve’s spring closes, sealing the water into the spa and preventing water loss. Over time the spring mechanism or the actual seal can fail. At this point the valve needs to be replaced. Generally these valves are designed so that you can replace the internal components only, so no plumbing should be required.
Many pool equipment systems contain multiple check valves, so it is important to understand the water flow through the equipment when looking to diagnose this issue. Often times we replace the internals of all the check valves in the system to prevent making multiple service trips.
Q: How long should I run my pool?
A: There are many variables that are taken into consideration when trying to determine how long a pool should run during the day.
What is the size of the pool?
Ultimately, the pool run time is based on how long it takes the pump to turn over and filter the entire body of water. Larger pools will need to run longer during the day to achieve proper filtration than smaller pools with less water. It is ideal to filter the entire body of water twice each day.
What is the outdoor temperature?
In the heat of the summer it is necessary to filter the entire body of water more frequently than in the dead of winter. As a general rule of thumb, we recommend running the pool’s filter pump one hour for every 10 degrees in temperature. For example, in July the temperatures in the Dallas area frequently reach 100 degrees. We recommend a minimum of 10 hours of run time each day, and it is ideal to run the pump during the heat of the day. During the winter time it is not necessary to turn over the body of water as frequently, as the temperatures to not cause the same bacteria growth as the summer heat. We do however recommend a minimum of 4-5 hours per day in the winter time.
What size is the pool pump?
The size or horsepower of the pump will also be a determining factor in how long the pump should run each day. A smaller or lesser horsepower pump will not move the same volume of water as a larger pump, thus requiring a longer run time to filter the same amount of water. This question of how long to run the pool can become even more complex if your pool is equipped with a variable speed pump. Is the pump running on low speed or on high speed?
How often is the pool used and by how many people?
During the swim season it may be necessary to run the filter pump longer while the pool is in use. The bather load will directly affect the water chemistry, and usage will introduce bacteria and other substances into the pool. For this reason it is always recommended that the filter pump is run while the pool is in use. Is there a family of four who is using the pool once each week or on the weekends, or is the pool consistently occupied by 10 or more people? Some of our commercial accounts have pools with a max load of 200 persons and require a 24 hour a day pump run time.
Overall, the pool run time is determined by taking into account all of these variables. From there, make an educated decision. If you notice that the pool is having clarity issues, use a trial and error method and increase the pool run time gradually to fine a run time that works for you.
Q: How long will my project take?
A: Swimming pools come in all shapes, styles, sizes, and include an infinite number of features and add-ons. Options such as spas, water features, outdoor kitchens and patios can impact the amount of time it takes to finalize the project. Some other things that might affect the timeframe of the construction process could be weather, the design choices as well as the site layout itself.
We know every project is unique, and our customer’s needs are our number one priority throughout the process. Once the financing is complete and the permits are acquired you will find that most projects are completed in 6 to 8 weeks. Here at Prestige Pool and Patio we strive to deliver the perfect product while still keeping the timetable short, but without sacrificing quality.
Watch out for companies that offer up a complete pool in less than 30 days. They typically cut corners and lower their standards in order to deliver a pool in such a short amount of time, which will leave the customer unsatisfied in the end. Here at Prestige Pool and Patio we use contractors who are specialized in each area of the construction process, such as the excavation, rebar, plumbing and gunite; ultimately delivering the best of both worlds to our customers.
The bottom line is that we have the same end goal as you. To complete the project as soon as possible while still delivering the highest quality product, so that you and your family can enjoy your backyard sooner rather than later.
