Install Above Ground Pools FAQs, answered by experts

There are some companies that offer acid washes that do not require pool draining. However, the process can take several days and requires a bit more elbow grease to scrub the pool surface compared to draining it entirely. Since your pool surface and age are both a factor, work with a professional to choose the best method.

The popular 12-by-24-foot oval above ground pool is ideal for a family of four or a group of four to five people at most. This above ground pool size is popular for balancing space in a backyard and easy use and leaves room for designing a pool deck or patio.

An easy way to know whether your sand filter has enough sand is to check how full the filter is and what the sand looks and feels like. The filter container should be two-thirds to three-quarters full of sand. Look for interior marks indicating the ideal sand level. If you put your hand into the sand, it should flow through your fingers without clumping. The filter pressure gauge is also an easy indicator—the right amount of sand leads to normal pressure, while too much or too little sand can cause high or low pressure.

You can avoid pool collapse—known as pool pop in an inground pool—if you follow the instructions on how to drain your pool safely. Wait for a temperate, dry day and slowly remove the water with a sump pump, hose, or the attached drains and hydrostatic plugs.

The total time to install an inground pool typically ranges from 8 weeks to 4 months. This timeline can be influenced by several factors, including permitting, site preparation, and the construction process itself.

Key phases and their typical durations include:

  • Permits: Obtaining necessary permits can take anywhere from two to six weeks.

  • Excavation and Site Preparation: This phase takes about a week but can be extended by problematic soil, unexpected ground conditions, or the need to move underground utility lines.

  • Construction: The actual build, including plumbing and electrical work, often takes one to two months. The pool material is a major factor here; a concrete pool needs about 30 days to cure, while installing a fiberglass or vinyl liner is much faster.

External factors can also cause significant delays:

  • Contractor Availability: Spring and summer are busy seasons, and high demand can lead to long waitlists, potentially adding months to your start date. It is often recommended to start planning and getting estimates up to a year in advance.

  • Other Delays: Weather, material shortages, complex designs, and other unforeseen challenges can extend the project timeline.
