Above-ground pool water delivery means a tanker truck brings clean bulk water to your yard and fills your above-ground pool in hours instead of days. It is the fastest way to fill a new pool, refill after a liner replacement or top off a pool on a private well, and it puts far less strain on your well or your household plumbing. A Clear Alternative fills permanently installed above-ground pools across Burlington, Camden, Atlantic, Gloucester, Salem, Cape May, Mercer and Monmouth counties. Call or text 856-856-5210 any time to check availability.

Which Above-Ground Pools Can Be Filled by Truck?

Truck delivery is built for permanently installed above-ground pools: steel, aluminum or resin wall pools with a vinyl liner, a proper base and a top rail. These pools are designed to hold thousands of gallons and take a steady fill.

We do not fill soft-sided, inflatable, frame-and-fabric or other temporary pool kits. A tanker's flow can shift or overload those pools, and their manufacturers generally recommend a slow, low-pressure fill from a garden hose. If you are not sure which kind you have, send us a photo when you request a quote.

How Much Water Does an Above-Ground Pool Hold?

Above-ground pools are easier to measure than in-ground pools because the depth is nearly the same everywhere. Measure the water depth you plan to fill to, usually about halfway up the skimmer opening, not the wall height.

• Round pool: diameter × diameter × water depth × 5.9 = gallons
• Oval pool: length × width × water depth × 5.9 = gallons (straight-sided ovals hold a little more, so check your manufacturer's capacity chart)

Some quick examples, all in feet:

• An 18-foot round pool filled to 4 feet holds roughly 7,600 gallons.
• A 24-foot round pool filled to 4 feet holds roughly 13,600 gallons.
• A 15 × 30 foot oval filled to 4 feet holds roughly 10,600 gallons.

Our tankers carry 6,200 gallons per load, so most above-ground pools need one to three loads. If the pool already has some water in it, measure how many inches you need to add and calculate only that portion. For in-ground pools and bigger jobs, our guide to filling a pool with a water truck walks through the same math.

Before the Truck Arrives: Prepping an Above-Ground Pool

An above-ground pool is only as good as its base, and the first few inches of water decide whether the liner sits smooth or wrinkled for its whole life. Here is the order most installers and liner manufacturers recommend.

1. Check that the pool is level

A pool that is out of level puts uneven pressure on the wall and bottom track as it fills. Check with a long level or a transit before any water goes in. Fixing a low side is easy with an empty pool and nearly impossible with a full one.

2. Set the liner and pull the air out

Hang the liner evenly, then use the shop-vac method many installers rely on: run a shop vacuum hose between the liner and the wall, seal the skimmer and return openings with tape, and let the vacuum pull the liner tight against the wall and floor. Most liner instructions say to leave the vacuum running until there is roughly 6 to 12 inches of water in the pool.

3. Start with a few inches and smooth the floor

Many liner manufacturers recommend putting the first inch or two of water in by garden hose, then walking the floor in clean, soft-soled shoes or using a soft push broom to work wrinkles toward the wall. Never pull the liner over the wall to remove a wrinkle. Once the floor is smooth, the truck can take over.

4. Protect the base and cove

Tell the driver where the liner is most delicate. We start the flow gently and can direct the hose onto a pad or folded scrap of old liner so the water does not dig into the sand base or cove.

5. Plan the hose route

The driver parks on the street or driveway and runs a large hose to the pool. Clear gates, open a path through fences and let us know about steep slopes, decks or tight side yards. The shorter and simpler the hose run, the smoother delivery day goes.

What Happens on Delivery Day

1. Walk-through. The driver checks the hose route, the pool and where you want the water to go in.
2. Gentle start. For above-ground liners, the first part of each load goes in slowly. Someone should stay at the pool to watch the liner and walls.
3. Full flow. Once the liner is seated, the load pumps out much faster. A full 6,200-gallon load typically unloads in roughly half an hour to an hour, depending on the hose run.
4. Watch the walls. If you see a wall bow inward, the bottom track shift or the liner pulling hard at the cove, stop the fill right away and call your installer. That usually points to a base or liner-fit problem that needs fixing before more water goes in.
5. Additional loads. Larger pools get a second or third load until the water reaches about mid-skimmer.

Fall Liner Replacements and Closing

Autumn is a busy time for above-ground liner replacements. Pool stores and installers have more openings after the summer rush, and replacing a liner in fall means the pool is ready to open in spring. It also means the pool needs to be filled again quickly.

• Do not leave a new liner empty. Above-ground liner manuals warn that the pool and liner should stay full of water. An empty or half-empty liner can shrink, shift or pull out of its track, especially as nights get cold.
• Fill before temperatures drop. Vinyl is more flexible and easier to smooth when it is warm. A fill on a mild afternoon is much easier than one on a cold morning.
• Close at the right level. Most above-ground pools are closed with water lowered only slightly below the skimmer and returns, or with skimmer plugs in place, not drained. Follow your pool manufacturer's closing instructions.
• Spring top-off. Winter covers and evaporation leave many pools low by opening day. A partial load in April or May brings the level back without hours of hose time.

Balancing Water After an Above-Ground Fill

Trucked pool water arrives clean and ready for your chemicals, but every fill still needs a starting balance:

• Run the pump and filter as soon as the water is above the skimmer.
• Test pH, total alkalinity, calcium hardness and chlorine before adding anything.
• Adjust alkalinity first, then pH, then add stabilizer and chlorine according to your pool store's or test kit's guidance.
• Retest after 24 hours and adjust again as needed.

Pool and hot tub water from a pool fill is non-potable and is not meant for household use. For a spa, see our hot tub water delivery page, and for ponds, construction and other large jobs see bulk water delivery.

Above-Ground Pool Fills Across Our Eight Counties

We fill above-ground pools throughout our service area: Burlington, Camden, Atlantic, Gloucester, Salem, Cape May, Mercer and Monmouth counties. A few local things to keep in mind:

• Sandy Pine Barrens soils. Much of Burlington, Atlantic, Camden and Gloucester County sits on loose, sandy soil. It drains well but can settle under a new pool, so a compacted, level base matters even more.
• Homes on wells. Many homes in rural Salem, Gloucester, Burlington and Monmouth County are on private wells. Filling a pool from a well can run the pump for hours and pull sediment or iron into new water. A truck fill avoids that.
• Shore properties. In Cape May and Atlantic County, narrow streets, parking rules and tight lots make it important to tell us about access ahead of time.
• Mercer and Monmouth suburbs. Fenced yards and long side-yard hose runs are common. Measure the distance from the curb to the pool before you call.

When to Call A Clear Alternative

Call us when you have a new above-ground pool ready to fill, a liner replacement scheduled, a pool that needs a big top-off, or a home on a well that cannot handle a long fill. Tell us the pool size and shape, how full it is now, and how close the truck can park, and we will help you figure out how many loads you need. A Clear Alternative has been family-run since 1991, from 9230 Collins Ave in Pennsauken. Call or text 856-856-5210, reach our office at 856-663-8088, or request a quote online.

Frequently Asked Questions

Can a water truck fill an above-ground pool?

Yes, as long as it is a permanently installed above-ground pool with proper walls, a base and a vinyl liner. We do not fill soft-sided, inflatable or temporary pools.

How many truckloads does an above-ground pool need?

Most need one to three loads. Our tankers carry 6,200 gallons, and a 24-foot round pool filled to 4 feet holds roughly 13,600 gallons, a little over two loads.

Should I put some water in with a hose first?

Many liner manufacturers recommend adding the first inch or two by hose and smoothing out floor wrinkles before the truck fill starts. It gives you a smooth liner and protects the base.

Will the truck damage my liner?

Not when the fill starts gently and the liner is properly set. We begin each load slowly and can direct the hose onto a pad. Stop the fill if a wall bows in or the liner pulls hard at the cove.

Can I get a new liner filled in the fall?

Yes. Fall is a good time for liner replacements, and a new liner should be filled promptly rather than left empty through cold weather.

Is pool fill water drinkable?

No. Pool fill water is non-potable and intended for pools, spas and similar uses only.
