When Your Bathtub Won’t Drain and Even the Plumber Is Stumped
There’s nothing more frustrating than stepping into a shower only to find your bathtub won’t drain standing water. You’ve tried plungers, drain snakes, and even called a professional—yet the problem persists. If you’ve landed here searching for “bathtub won’t drain standing water plumber can’t fix Reddit,” you’re not alone. Thousands of homeowners have turned to Reddit’s plumbing communities for real-world advice when traditional fixes fail. In this guide, we’ll break down why this happens, what experts say, and actionable steps you can take—backed by real user experiences and professional insights.
Why Won’t My Bathtub Drain Even After a Plumber Visit?
When a licensed plumber can’t resolve your drainage issue, it’s natural to feel confused or skeptical. However, several underlying causes might be at play:
- Deep or Complex Clogs: Some blockages lie far beyond the reach of standard augers, especially in older homes with corroded or misaligned pipes.
- Venting Issues: Improper venting can create airlocks that prevent water from flowing smoothly, mimicking a clog.
- Pipe Damage: Collapsed sections, bellied pipes (sagging), or tree root intrusion may require camera inspection and excavation.
- Incorrect Diagnosis: Occasionally, the initial assessment may miss secondary issues like mineral buildup or foreign objects lodged deep in the line.
According to a 2024 survey by the National Association of Home Builders, 12% of drainage complaints involve complications that standard snaking cannot resolve without advanced diagnostics.
“If a plumber says they can’t fix it, it often means the problem isn’t a simple clog—it’s a systemic issue,” says Mike Frazio, a master plumber with 25 years of experience featured on r/Plumbing.

What Do Reddit Users Recommend When a Plumber Fails?
Reddit’s plumbing subreddits (like r/Plumbing, r/HomeImprovement, and r/DIY) are goldmines for crowd-sourced solutions. Here’s what experienced users consistently suggest:
1. Use a Wet/Dry Vacuum for Suction Power
Many Redditors swear by using a shop vac in “wet” mode to suck out stubborn clogs.
How-to:
- Seal the overflow drain with a wet rag.
- Place the vacuum hose tightly over the main drain.
- Run for 30–60 seconds.
- Repeat 2–3 times if needed.
“My plumber gave up, but a $60 shop vac cleared 3 inches of standing water in minutes,” shared u/TubRescue2023.
2. Try an Enzymatic Drain Cleaner (Not Chemical)
Unlike harsh chemical cleaners that can damage pipes, enzymatic cleaners use bacteria to break down organic matter over 24–48 hours.
Recommended brands mentioned on Reddit:
- Bio-Clean
- Green Gobbler
- Earthworm Family Safe Drain Opener
3. Inspect the P-Trap and Overflow Assembly
In many cases, the clog isn’t in the main line but trapped in the P-trap or overflow channel.
Steps:
- Remove the drain stopper mechanism.
- Unscrew the overflow plate (usually 2 screws).
- Use a flexible brush or small auger to clear debris.
4. Request a Camera Inspection
If previous attempts fail, insist on a sewer camera inspection. This reveals cracks, offsets, or root intrusions invisible to the naked eye. Cost ranges from $150–$300 but can save thousands in unnecessary repairs.
Step-by-Step: DIY Fixes Before Calling Another Plumber
If you’re handy and want to avoid another service call, follow this detailed protocol:
Materials Needed:
- Wet/dry vacuum
- Plunger (flange type)
- Drain snake (minimum 25 ft)
- Bucket and towels
- Flashlight
- Adjustable wrench
- Enzymatic drain cleaner
Procedure:
- Remove Standing Water
Use a cup or wet vac to remove as much water as possible. Aim for less than 1 inch remaining. - Plunge Correctly
- Fill the tub with 2–3 inches of warm water (22–28°C ideal).
- Cover the overflow drain with a wet cloth.
- Plunge vigorously for 20–30 seconds. Repeat 3 times.
- Snake the Drain
- Insert the auger slowly until resistance is felt.
- Rotate clockwise while pushing forward.
- Retrieve and clean the hook end. Repeat until no debris returns.
- Flush with Hot Water + Enzymatic Cleaner
- Pour 2 liters of hot (not boiling) water down the drain.
- Apply enzymatic cleaner per label instructions.
- Wait 24 hours before testing drainage.
- Test and Monitor
Run water for 2 minutes. If it drains within 30 seconds, success! If not, proceed to camera inspection.
Common Mistakes That Make Drain Problems Worse
Avoid these pitfalls that Reddit users warn against:
| Mistake | Consequence | Better Alternative |
|---|---|---|
| Using chemical drain cleaners repeatedly | Corrodes pipes, creates toxic fumes | Use enzymatic cleaners or mechanical removal |
| Ignoring slow drainage until it’s fully blocked | Leads to backup and water damage | Address early signs immediately |
| Over-snaking without knowing pipe layout | Can puncture old pipes | Get a camera inspection first |
| Not cleaning the overflow channel | Clog remains hidden | Disassemble and clean overflow assembly |
When to Call a Specialist (and What to Ask)
If DIY efforts fail, it’s time to call a drain specialist—not just a general plumber. Look for professionals who offer:
- Video camera inspections
- Hydro-jetting services (high-pressure water cleaning)
- Trenchless pipe repair options
Questions to ask before hiring:
- “Do you provide a written diagnosis after camera inspection?”
- “What’s your success rate with recurring clogs?”
- “Are your technicians licensed and insured?”
- “Do you offer a warranty on the repair?”
According to Angi (formerly Angie’s List), homeowners who opt for camera inspections before major repairs save an average of $420 by avoiding unnecessary pipe replacement.
FAQ: Your Top Questions Answered
Q1: Why does my bathtub still hold water after a plumber snaked it?
A: The clog may be deeper than the snake reached, or there could be a venting issue, pipe belly, or collapsed section requiring camera diagnosis.
Q2: Can hair really cause a clog that a plumber can’t fix?
A: Yes—if hair combines with soap scum and minerals over years, it forms a hardened mass that standard tools can’t dislodge without hydro-jetting or pipe access.
Q3: How much does a sewer camera inspection cost?
A: Typically $150–$300 in the U.S., depending on location and company. Many plumbers apply this fee toward repair costs if you hire them.
Q4: Is it safe to use a wet/dry vac on my drain?
A: Yes, as long as you use the “wet” setting and create a tight seal. Avoid using dry mode, which can damage the motor.
Q5: Should I try baking soda and vinegar?
A: While popular, this combo creates a foaming reaction that rarely clears serious clogs. It’s better for maintenance than emergency fixes.
Q6: How do I know if my pipes are damaged vs. just clogged?
A: Recurring clogs, gurgling sounds, or multiple fixtures backing up suggest pipe damage. A camera inspection is the only definitive way to confirm.
Conclusion: Don’t Give Up—Solutions Exist Beyond the First Plumber Visit
Dealing with a bathtub that won’t drain standing water—especially when a plumber can’t fix it—is incredibly stressful. But as countless Reddit threads prove, persistence pays off. Whether it’s using a shop vac, requesting a camera inspection, or switching to a drain specialist, there’s almost always a solution short of full pipe replacement.
