Product Snapshot: What the INTEX 26329EH Ultra XTR 18ft Includes and Key Specs
While you’re sizing up backyard pools, note that the INTEX 26329EH Ultra XTR 18ft is a complete above-ground set that pairs a durable 18 ft x 52 in round pool (holds ~700 gallons) with a Krystal Clear sand filter pump and a Deluxe Automatic Vacuum Cleaner. You get galvanized alloy steel frame, 3-ply PVC liner, ladder, ground cloth, and a 6-function sand filter valve. Assembly’s tool-free with snap-together parts; follow installation tips for level placement and secure T-joints. Seasonal maintenance is straightforward: winterize the pump, patch liner as needed, and store the vacuum to extend service life.
Build and Durability Tested: Frame, Liner, Fittings, and Warranty Details
Because Intex designed the Ultra XTR frame from high-quality galvanized alloy steel with precision T-joints and a snap-together locking system, you get a rigid, weather-resistant structure that goes up quickly without tools or pins. You’ll notice the frame passed corrosion testing protocols and offers UV resistance at joint surfaces, reducing long-term degradation. The 3-ply PVC/vinyl liner shows solid seam reinforcement and puncture resistance; seams are taped and heat-welded to limit failures. Fittings feel robust during stress testing, and included repair patching is practical. Coverage is backed by a straightforward 2-year manufacturer warranty for peace of mind.
Setup, Footprint, and Real-World Assembly Time for a Backyard Install
For a smooth backyard install, plan a level footprint slightly larger than the pool’s 18 ft diameter—allow at least 2 ft clearance all around (a 22 ft x 22 ft level area) so you can position the frame, ladder, and pump without crowding. You’ll assess yard leveling first: remove debris, mark a circle, and use a plate compactor or hand tamper to firm soil. Follow assembly tips: assemble Ultra XTR frame on its side, then raise, snap T-joints, and align liner. Two people can complete setup, ground cloth, and fill start in about 3–4 hours; full fill takes longer.
Filtration & Cleaning Performance: Sand Filter Pump and Automatic Vacuum in Practice
After you’ve got the pool assembled and filling, you’ll quickly notice how the filtration and cleaning gear defines water clarity and maintenance time. You’ll find the Krystal Clear sand filter delivers consistent filter efficiency for typical backyard debris; run times of 6–8 hours clear cloudy starts quickly. Backwash and rinse cycles are straightforward with the 6-function valve. The Deluxe Automatic Vacuum connects to the inlet and pulls roughly 700 gal/hour; it scoops sand and leaves with minimal intervention. Expect moderate vacuum noise while running—noticeable but not disruptive. Overall, system performance balances low upkeep with dependable clarity.
Who This Pool Is Best For and Alternatives to Consider
While the Ultra XTR 18ft suits homeowners who want a sturdy, low-maintenance seasonal pool, it’s especially good if you need a roomy family swim area that’s easy to assemble and maintain. You’ll appreciate the galvanized frame, snap-together assembly, and included sand filter plus automatic vacuum for straightforward upkeep during frequent family gatherings. It’s ideal if you want a durable, portable summer focal point and can dedicate yard space and setup time. If you need cheaper or smaller options, consider Intex Prism Frame models or Bestway Steel Pro Lite as budget alternatives with simpler pumps and lower capacity.
Some Questions Answered
Can This Pool Be Used Year-Round in Mild Climates?
Yes — you can use it year-round in mild climates if you commit to winter maintenance and proper freeze protection. You’ll need to winterize the pump, remove or secure the ladder and vacuum, cover the pool, and maintain water chemistry to prevent algae. Monitor for occasional cold snaps; the 3-ply liner and galvanized frame resist weather, but prolonged freezing can still damage seals and fittings, so stay proactive.
Are Replacement Liners Readily Available for This Model?
Yes — replacement availability is good. You’ll find compatible liners from Intex and third-party sellers sized for 18 ft x 52 in pools; check liner compatibility by matching model 26329EH dimensions and mounting style. Order genuine Intex liners when possible for exact fit and material specs; aftermarket options can save money but may need minor trimming. Confirm return policy and warranty coverage before purchase to avoid fit or durability issues.
What Is the Estimated Total Weight When Filled With Water?
About 6,200 pounds approximate weight when filled. You’ll combine the pool’s water capacity (~700 gallons) with the empty structure’s weight (roughly 200–300 lbs). Since one gallon of water weighs about 8.34 lbs, 700 gallons ≈ 5,838 lbs; add 200–300 lbs for frame, liner, and accessories to get ~6,038–6,138 lbs, commonly rounded to ~6,200 lbs as a safe approximate weight.
Can the Sand Filter Operate on a Timed Schedule?
Yes — the sand filter pump itself doesn’t include a built‑in timer, but you can add timer compatibility via an external pool timer or programmable outlet. You’ll get programmable cycles (daily on/off scheduling) to control run time and conserve energy. Make sure the timer matches the pump’s voltage/amperage and is installed per local code; a professional hookup avoids voiding warranty and makes for safe, reliable automated filtration.
Is Electrical Grounding Required for the Pump Setup?
Yes — you should follow electrical grounding requirements for the pump. Electrical grounding reduces shock risk and helps meet Safety regulations; it’s a critical safety step when installing the sand filter pump. You’ll want a properly grounded outlet, GFCI protection, and to follow the pump manual and local codes. If you’re unsure, get a qualified electrician to verify grounding, circuit protection, and compliance before operating the system.
