Bring these pool details

MOST IMPORTANT

Your gallons—or your measurements

Know your pool’s capacity? Bring that number in gallons. If not, bring:

  • The pool’s shape
  • Length and width—or diameter for a round pool
  • Shallow and deep water depths

We can help estimate the gallons from your measurements.

Pool type
Above-ground, inground, or a spa/hot tub.
Filter type
Sand, cartridge, or DE (diatomaceous earth). Not sure? Bring a photo.
Water features
Waterfalls, fountains, spa spillovers, or other features—or let us know you have none.
Salt or chlorine?
Does a salt system make your chlorine, or do you add liquid chlorine, tablets, or granules?

Equipment photos help us the most

Bring photos on your phone. We’ll help identify what you have.

  • Your pump and filter
  • Any salt cell or chlorine feeder
  • Clear close-ups of equipment labels
Need help estimating your gallons?Use the pool calculator with your measurements.

Estimate your pool’s gallons

Measure inside the pool at the waterline. Use the actual water depth, rather than the height of the pool wall. Enter measurements in feet: 4 feet 6 inches = 4.5 feet.

Bring your pool’s shape, measurements and equipment photos to the store. We’ll help you work out the gallons when you come in for free water testing.

This is an estimate for simple shapes with flat floors or even slopes. Steps, benches, tanning ledges and changes in slope affect the actual gallons. If you know your manufacturer’s capacity, bring that figure instead. See Sun Pools model capacities
