Clogged drains are more than just an inconvenience—they can disrupt your entire day. Whether it’s slow-draining kitchen sinks or a completely blocked bathroom pipe, you need a solution that’s both powerful and safe for your plumbing. That’s where Great Value Drain Cleaner Maximum Strength Safe With PVC Plumbing comes in. Trusted by millions of U.S. households and available at Walmart, this product promises fast-acting clog removal without damaging modern PVC piping systems. In this guide, we’ll break down everything you need to know—from how it works to step-by-step usage—so you can unclog with confidence.
What Is Great Value Drain Cleaner Maximum Strength?
Great Value Drain Cleaner Maximum Strength is a heavy-duty liquid drain opener sold exclusively at Walmart under its private-label brand. Formulated to dissolve hair, grease, soap scum, and other common organic blockages, it’s designed specifically to be safe for use in PVC, plastic, and metal plumbing systems—a critical feature given that over 80% of U.S. homes built after 1980 use PVC pipes (U.S. Census Bureau, 2023).
Unlike older caustic formulas that could warp or crack plastic pipes, this version uses a balanced alkaline blend (primarily sodium hydroxide) that generates heat through a controlled chemical reaction—enough to melt clogs but not damage pipe integrity when used as directed.
💡 Pro Tip: Always check your pipe material before using any chemical drain cleaner. If unsure, consult a plumber or look for white/gray rigid pipes under your sink—those are typically PVC.
Is It Really Safe for PVC Pipes? Here’s the Science
One of the most common concerns homeowners have is whether chemical drain cleaners will harm their plumbing. The short answer: Yes, Great Value Maximum Strength is safe for PVC—if used correctly.
PVC (polyvinyl chloride) pipes tolerate temperatures up to 140°F (60°C). Great Value’s formula heats up during the reaction—but studies show it stays well below this threshold when diluted with water as instructed. According to the Plastics Pipe Institute, properly formulated alkaline drain openers pose minimal risk to PVC when contact time is limited to 15–30 minutes.
However, never mix this product with other cleaners (especially bleach or acid-based products), as that can create toxic fumes or excessive heat that can damage pipes.
For reference, here’s how it compares to other popular brands:
| Product | Safe for PVC? | Active Ingredient | Max Contact Time |
|---|---|---|---|
| Great Value Maximum Strength | ✅ Yes | Sodium Hydroxide | 30 min |
| Drano Max Gel | ✅ Yes | Sodium Hydroxide | 15–30 min |
| Liquid-Plumr Pro-Strength | ✅ Yes | Sodium Hydroxide | 15 min |
| Generic Acid-Based Cleaners | ❌ No | Sulfuric Acid | Not recommended |

How to Use Great Value Drain Cleaner Maximum Strength (Step-by-Step)
Follow these steps carefully to maximize effectiveness and protect your pipes:
- Clear standing water from the sink or tub. If water won’t drain at all, remove as much as possible with a cup.
- Pour 17 oz (half the bottle) directly into the drain. Do not dilute it beforehand.
- Wait 15–30 minutes. For tough clogs, wait the full 30 minutes—but never exceed it.
- Flush with 2–3 cups of warm (not boiling) water, around 22–28°C (72–82°F).
- Repeat if necessary, but no more than twice in 24 hours.
⚠️ Safety First: Wear gloves and eye protection. Ensure the room is well-ventilated. Keep children and pets away during use.
If the clog persists after two attempts, do not keep adding more cleaner. You may have a deeper blockage requiring a plumber or mechanical snake.
Pros and Cons: Is It Worth It?
✅ Advantages
- Affordable: Typically under $3 per bottle at Walmart—much cheaper than name brands.
- PVC-safe formula: Verified by independent plumbing experts.
- Fast-acting: Clears most minor clogs in under 30 minutes.
- Widely available: In-store and online via Walmart.com.
❌ Limitations
- Not for complete blockages: Won’t work if zero water passes through.
- Not septic-safe: Avoid if you have a septic tank (check label).
- Strong odor: Chemical smell during use—open windows!
Compared to enzymatic or natural alternatives (like baking soda + vinegar), this product works faster but is harsher on the environment. For routine maintenance, consider gentler options. But for urgent clogs? Great Value delivers.
Real User Experience: Does It Work?
In a 2025 survey of 1,200 U.S. homeowners conducted by HomeFix Weekly, 78% reported complete clog removal after one use of Great Value Maximum Strength. One user from Ohio shared:
“My kitchen sink was backing up with greasy gunk. I poured half the bottle, waited 20 minutes, and flushed—it drained instantly. And my PVC pipes (installed in 2019) showed zero damage.”
That said, 12% said it only partially worked, usually due to hair-packed bathtub drains—a scenario where a manual auger might be better first.
How It Compares to Professional Solutions
While plumbers often use motorized snakes or hydro-jetting for severe blockages, chemical cleaners like Great Value are ideal for early-stage clogs. The average service call costs $150–$300 (HomeAdvisor, 2025), so using a $2.98 bottle first makes financial sense.
Just remember: Prevention beats cure. Use drain strainers, avoid pouring grease down sinks, and flush drains weekly with hot water to reduce buildup.

FAQ Section
Q1: Can I use Great Value Drain Cleaner in a garbage disposal?
A: No. Never pour chemical drain cleaners into a garbage disposal. The blades can splash the solution, causing damage or injury. Instead, run cold water and use the disposal normally, or try ice cubes + salt to clean it.
Q2: Is it safe for septic systems?
A: No. The label explicitly states it’s not septic-safe. The strong alkali can kill beneficial bacteria in your tank. Use septic-safe enzymatic cleaners instead.
Q3: How often can I use it?
A: Limit use to once every 2–4 weeks for maintenance. Overuse can degrade pipe seals over time—even with PVC-safe formulas.
Q4: What should I do if it doesn’t work?
A: Stop using chemicals. Try a plunger or a hand-crank drain snake ($10–$20 at hardware stores). If still blocked, call a licensed plumber.
Q5: Can I mix it with vinegar or baking soda?
A: Absolutely not. Mixing chemicals can cause dangerous reactions, including heat spikes or chlorine gas. Use one product at a time—and never combine cleaners.
Q6: Where can I buy it?
A: Exclusively at Walmart—both in-store and on Walmart.com. Look for the red-and-white “Maximum Strength” label.
