Installing a drop-stitch pool is different from assembling a steel frame pool. There's no frame to connect, no hardware to torque, no liner to hang. The entire physical setup — site preparation, inflation to working pressure, and sand filter connection — takes approximately one hour for two people.

The fill phase (running water from a garden hose) is passive and takes 19–53 hours depending on pool size. You start the hose, let it run, and come back. This guide covers the installation in the order you'll actually do it.

Before You Start

What you need from GIGI: Your pool package includes the pool, a sand filter 330W, an electric inflation/deflation pump, and a repair kit. (Pool cover and carrying bag sold separately.) Everything else listed here is separate.

What you need to source:

• A standard garden hose (longer is more convenient — a 50–100 ft hose reaches most backyard spots without tangling)
• A garden hose adapter if your outdoor spigot uses a non-standard fitting
• A level — a simple carpenter's level or even a free smartphone app
• Pool start-up chemicals (pH balancer, chlorine tablets, test strips)

How long does the full setup take?

• Physical installation (Steps 1–5): approximately 1 hour with two people
• Water filling (Step 6): 19–24 hours (13ft), 30–37 hours (16ft), 42–53 hours (19ft)

Plan to start filling the day before your first swim.

How many people? Two is recommended. One person can do every step alone, but unfolding and positioning a pool that spans 4–6 meters is significantly easier with a second pair of hands.

Step 1 — Choose and Prepare Your Site

Space requirements (minimum):

Add 60–35 in of clearance around the pool on all sides — you'll want to walk around it for maintenance.

Surface requirements:

• Any firm, flat surface: grass, packed dirt, concrete, or patio
• The ground must be level within approximately 1 in across the full diameter of the pool
• Never place the pool on loose gravel, soft sand, or thick mulch — these shift under load

Checking for level: Place your level across the center of the planned area in two perpendicular directions. A 1 in or less variation across the pool diameter is acceptable. More than that, and you'll need to fill or compact the low areas before proceeding. An unlevel pool puts uneven stress on the walls and affects water depth across the pool.

Ground prep:

1. Walk the area and remove any rocks, sticks, roots, or sharp debris
2. Trim grass short if it's long — grass that grows under the pool can puncture the base
3. Lay the included protective ground cloth (or a separate tarp) over the cleaned area
4. Optional: place a foam pool pad or puzzle mat under the ground cloth for added insulation and comfort

Note: Do not place the pool on asphalt or dark-colored pavement in direct sunlight without a thick protective layer. Heat absorption from dark surfaces can reach temperatures that damage DWF material over time.

Step 2 — Unfold the Pool

With the ground cloth in place, carry the pool bag to the center of your prepared area.

1. Remove the pool from the bag
2. Lay it flat in the center of the ground cloth, with the valve side facing up
3. Unfold the pool gradually — it will be folded in panels and rolled. Unfold the panels outward from the center, spreading it to its full diameter
4. Orient the sand filter inlet/outlet ports so they face toward your preferred access point (typically closest to your power outlet)
5. Confirm the pool is roughly centered on the ground cloth with all edges sitting on covered ground

Tip: On a warm day, let the pool sit in the sun for 10–15 minutes before inflating. Slightly warmed DWF material is more supple and inflates more evenly. Do not inflate in temperatures below 5°C (40°F).

---

Step 3 — Inflate to 10–12 PSI

Connect the pump:

1. Locate the main inflation valve on the pool (a large valve, usually at the top of one wall section)
2. Connect the included electric pump hose to this valve — the fitting is a push-and-lock connector
3. Plug the pump into a standard 110V outlet
4. Set the pump to inflation mode and turn it on

What to expect during inflation:

The pool will begin to take shape within a few minutes. The walls will rise and the pool will expand outward to its full diameter. As inflation continues, the walls stiffen progressively.

Target pressure: 10–12 PSI on the gauge integrated into the pump or on a separate gauge at the valve. The pool is firm and ready when it reaches this range.

Maximum pressure is 15 PSI — never exceed this. Exceeding maximum pressure voids the warranty and risks seam failure.

Inflation time:

• Pool 13ft: approximately 15–20 minutes
• Pool 16ft: approximately 20–30 minutes
• Pool 19ft: approximately 25–35 minutes

When inflation is complete:

1. Close the valve and disconnect the pump hose
2. Walk around the pool and press on the walls at multiple points — they should feel firm with minimal give, similar to a well-inflated car tire
3. Check that the base is sitting flat on the ground cloth without bunching or gaps underneath

Attention: If a section of the wall feels noticeably softer than others, check the valve seal. If the pressure equalizes within the pool after sealing the valve and the issue persists, locate and mark the area and use the repair kit. Do not fill with water if the pool holds significantly less than 10 PSI.

Step 4 — Connect the Sand Filter 330W

The sand filter 330W ships pre-filled with filtering sand (verify this in the documentation included in your package — some configurations ship sand separately). Position it outside the pool near the designated filter ports.

Connection steps:

1. Locate the two filter ports on the pool wall (inlet and outlet, typically labeled)
2. Connect the included hoses from the sand filter: one from the pump outlet to the pool return port, one from the pool suction port to the pump inlet
3. Ensure all fittings are hand-tight — use thread seal tape on threaded connections if your configuration requires it
4. Position the filter on flat ground, in the shade if possible — direct prolonged sun exposure on the filter body reduces its operational life
5. Plug the filter into a standard 110V outlet but do not turn it on yet — wait until there is water in the pool

Note on filter orientation: The sand filter 330W has a labeled "FILTER" and "BACKWASH" valve setting. Confirm the valve is set to FILTER before first operation. The backwash setting is only used during maintenance — it reverses flow to clean the sand bed. Running on backwash with no backwash hose attached will empty sand out of the filter.

Step 5 — Final Pre-Fill Check

Before you start filling, take five minutes for a walkthrough:

• Pool fully inflated to 10–12 PSI
• All walls firm and upright with no soft spots
• Pool base sitting flat on the ground cloth, no bunching
• Ground cloth extending 12 in or more beyond the pool perimeter all around
• Sand filter positioned and hoses connected
• Sand filter valve set to FILTER position
• All inflation valves closed and seated
• Power outlets identified for pump and filter (separate circuits preferred for the 19ft)

Step 6 — Fill with Water

Connect your garden hose to your outdoor spigot and run the other end into the center of the pool.

Fill times (standard garden hose, approximately 12–15 liters/minute):

Fill to 90% of wall height. For the 5 ft walls: fill to approximately 53 in (about 53 inches). Leave 6 in of freeboard — the space between waterline and pool rim. This margin prevents water from spilling when people enter or move in the pool.

Tip: If your water pressure is lower than average (common in some suburban areas), fill time will be longer. A hose flow rate of 8–10 liters/minute would add 5–10 hours to the estimates above.

Once water reaches approximately 12 in (12 inches): Turn on the sand filter. Running the filter while filling begins water circulation and prevents stagnant zones at the base.

During filling:

• Check inflation pressure every 8–10 hours — the walls may need a small top-up as DWF material stretches slightly under water load during the first fill. Target: 10–12 PSI throughout.
• Monitor the pool base — if one side appears to have more water than the other (visible tilt), the site may be less level than initial assessment. If the difference is more than 2 in at the waterline, drain, recheck the site level, and refill.

Step 7 — First Chemical Treatment

Do not add chemical treatment to a pool that has just been filled with untreated tap water and left standing. Treat within 4–6 hours of completing the fill.

Target chemistry for first fill:

First treatment sequence:

1. Test your tap water with a standard pool test strip kit — know your starting pH and alkalinity before adding anything
2. Adjust pH first if necessary (lower with muriatic acid or sodium bisulfate; raise with sodium carbonate)
3. Adjust alkalinity if necessary (sodium bicarbonate to raise, muriatic acid to lower)
4. Add a shock treatment (calcium hypochlorite or sodium dichloro-s-triazinetrione) to raise free chlorine to 3–5 ppm for the initial treatment
5. Run the sand filter for at least 8 hours after treatment before testing again
6. Test and adjust to target ranges — then the pool is ready for swimming

Note on dosing: Always dose by volume. The GIGI 16ft pool holds approximately 7,000 gallons. Dosing a 7,000-gallon pool with the same amount you'd use for a 2,000-gallon pool under-doses and leaves you with inadequate sanitation. Read the label — doses are specified per 10,000 gallons or per 1,000 gallons, and scale accordingly.

Common Mistakes to Avoid

Skipping the level check. A pool installed on a 2 in slope looks fine until it's full — at which point one side has significantly more water pressure than the other, the pool base lifts on the low side, and you have an uneven (and potentially unsafe) installation. Three minutes with a level saves this headache.

Over-inflating. The 15 PSI maximum is a hard limit. Some users think "firmer is better" and push past 12 PSI. Above 15 PSI, seam stress increases sharply. The pool may not fail immediately, but repeated over-inflation damages seams over time and voids the warranty.

Filling before the site is ready. Once the pool is full, it weighs 17,000–84231 lbs (37,000–84,000 lbs) depending on model. Moving it requires a full drain. Get the site right before you fill.

Running the filter dry. The sand filter's impeller runs on water — running it with no water in the pool can damage the pump motor. Don't turn on the filter until there's at least 12 in of water in the pool.

Forgetting the first chemical treatment. Tap water sitting at 30°C (86°F) in a Texas summer can develop algae within 24–48 hours. Treat the water within a few hours of completing the fill.

Using an undersized ladder. Standard pool ladders are made for 52-inch (52 in) pools. On a 5 ft pool, the top step sits below the rim, which creates a safe entry/exit problem. Use the GIGI 59-inch drop-stitch ladder or a ladder rated for 59-inch pool walls.
