Can I Use Pipe for My Above Ground Pool Plumbing?

Thinking about setting up or repairing your above ground pool plumbing and wondering, “Can I use pipe for my above ground pool plumbing?” You’re not alone. Many pool owners tackle this exact question every summer—especially when leaks appear or they’re upgrading from a basic kit. The short answer is yes, but not just any pipe will do. Choosing the wrong type can lead to leaks, structural damage, or even void your pool’s warranty. Let’s walk through everything you need to know—safely, affordably, and effectively.

What Types of Pipes Are Used in Above Ground Pool Plumbing?

Above ground pools typically operate under low pressure (usually under 10 PSI) compared to in-ground systems, which can exceed 50 PSI. This means you don’t need industrial-grade piping, but you do need materials rated for constant water exposure, UV resistance, and temperature fluctuations.

The most common options include:

• PVC (Polyvinyl Chloride) – Rigid, durable, and widely used.
• CPVC (Chlorinated Polyvinyl Chloride) – Handles higher temps but is less common for pools.
• Flexible PVC or Vinyl Hose – Often included in starter kits.
• ABS (Acrylonitrile Butadiene Styrene) – Used in drains, but not recommended for pressurized plumbing.
• PEX (Cross-linked Polyethylene) – Flexible and freeze-resistant, but not UV-stable—risky for outdoor use unless shielded.

Expert Insight: According to the Association of Pool & Spa Professionals (APSP), rigid PVC (Schedule 40) is the go-to for above ground pool return and suction lines due to its pressure rating and chemical resistance.

Can I Use Regular Household PVC Pipe?

This is a very common misconception. While standard white PVC pipe from your local hardware store looks similar to pool-grade PVC, not all PVC is created equal.

Key Differences:

Important: Using non-pool-rated PVC may void your pool’s warranty and lead to premature cracking—especially in sunny or cold climates.

💡 Pro Tip: Always check for markings like “NSF-PW” (National Sanitation Foundation – Potable Water) or “ASTM D1785” for pressure-rated PVC. Pool supply stores sell UV-stabilized Schedule 40 PVC specifically for this application.

Step-by-Step: Installing Pipe for Your Above Ground Pool Plumbing

If you decide to upgrade from flexible hoses to rigid PVC, here’s how to do it safely:

Tools & Materials Needed:

• UV-resistant Schedule 40 PVC pipe (1.5” or 2” diameter, depending on pump size)
• PVC primer and cement (pool-rated)
• Pipe cutter or hacksaw
• Measuring tape
• Deburring tool
• Pool pump and filter (already installed)

Installation Steps:

1. Turn Off Power – Always disconnect the pump from electricity before working.
2. Drain Water Below Connection Points – Use a submersible pump if needed.
3. Measure & Cut Pipe – Leave 1–2 inches of extra length for alignment.
4. Deburr Edges – Smooth cut ends to prevent leaks and ensure proper sealing.
5. Dry-Fit First – Assemble without glue to confirm angles and lengths.
6. Apply Primer, Then Cement – Use a thin, even coat on both pipe and fitting. Insert fully with a 1/4 turn.
7. Hold for 30 Seconds – Prevent misalignment while cement sets.
8. Wait 2–4 Hours – Let cure before refilling or turning on the pump.

⚠️ Safety Note: Never use regular PVC cement indoors without ventilation. Choose low-VOC, pool-specific formulas when possible.

Pros and Cons: Rigid Pipe vs. Flexible Hose

Many above ground pools ship with corrugated vinyl hoses. Should you upgrade?

Rigid PVC Pipe

✅ Pros:

• More durable (lasts 10–15+ years)
• Less prone to kinking or algae buildup
• Better water flow (smooth interior)
• Looks cleaner and more professional

❌ Cons:

• Harder to install (requires precise measurements)
• Less forgiving on uneven ground
• Higher upfront cost

Flexible Vinyl Hose

✅ Pros:

• Easy to install and adjust
• Absorbs minor ground shifts
• Cheaper and widely available

❌ Cons:

• Degrades in 2–5 years (UV + chlorine)
• Prone to kinks and reduced flow
• Can harbor algae in corrugations

📊 Stat Insight: A 2023 survey by Pool & Hot Tub Alliance found that 68% of above ground pool owners who switched to rigid PVC reported fewer maintenance issues within one season.

What Does the Building Code Say?

While most residential above ground pools are not subject to strict plumbing codes (unlike in-ground pools), they must still comply with manufacturer guidelines and local safety ordinances.

For example:

• The International Residential Code (IRC) doesn’t regulate temporary above ground pools under 24” depth, but deeper models may require GFCI protection and secure plumbing.
• Always follow your pool’s manual—using non-approved materials often voids liability coverage.

You can learn more about plumbing materials standards on Wikipedia’s PVC page, which outlines chemical composition and pressure ratings used globally.

FAQ Section

Q1: Can I use ABS pipe for my above ground pool?

A: No. ABS is designed for drain-waste-vent (DWV) systems, not pressurized water. It’s brittle in sunlight and not rated for pool chemicals. Stick with PVC.

Q2: Is PEX pipe safe for above ground pool plumbing?

A: Only if it’s protected from sunlight. PEX degrades rapidly under UV exposure. If buried underground or in conduit, it’s acceptable—but rigid PVC is still preferred for longevity.

Q3: What size pipe should I use?

A: Most above ground pools use 1.5-inch plumbing. Larger pools (24+ ft diameter) or high-flow pumps (1.5 HP+) benefit from 2-inch pipe to reduce resistance and improve circulation.

Q4: How long does pool plumbing last?

A: Flexible hoses last 2–5 years. Properly installed UV-resistant PVC can easily last 10–20 years with minimal maintenance.

Q5: Can I mix flexible hose and rigid pipe?

A: Yes—many DIYers use rigid PVC for main runs and short vinyl hoses near the pump for vibration absorption. Just ensure all connections are secure and leak-tested.

Q6: Do I need glue for PVC pool plumbing?

A: Absolutely. Never rely on friction-fit connections. Use pool-rated PVC cement to create a watertight, permanent seal. Dry joints will fail under pressure.

Conclusion

So—can you use pipe for your above ground pool plumbing? Yes, and you should, if you want better performance, fewer leaks, and long-term savings. Just make sure you’re using UV-resistant, pool-rated PVC, not standard household pipe. With the right materials and a careful installation, your plumbing will run smoothly for years.

If this guide saved you time or prevented a costly mistake, share it with fellow pool owners on Facebook or Pinterest! And don’t forget to check your local pool supply store for pipe that’s certified for outdoor, chemical-resistant use.

🌞 Your pool should be about fun—not plumbing headaches. Choose wisely, install safely, and enjoy crystal-clear water all season long.
