Flexible Tub Drain Pipes - The Easy Fix for Any Drain Angle

Is your bathtub drain clogged beyond repair or leaking from years of buildup? Does the awkward angle of the existing drain pipe make repairs seemingly impossible? Many homeowners face this frustrating predicament, resigned to either living with a dysfunctional tub or paying big bucks to rip it out and replace it entirely. Fortunately, there is an easy fix that doesn't involve heavy tools or demolition - retrofitting with a flexible tub drain pipe. Read on to learn why flexible plastic drain pipes could be the perfect solution for refreshing your tub without a total remodel.

What is a Flexible Tub Drain Pipe?

A flexible tub drain pipe refers to bendable plastic piping used to replace rigid drain pipes under bathtubs and showers. Rather than requiring perfectly straight runs, these pipes can conform to any angle using just hand pressure. The flexible piping enables easier access, positioning, and installations in tight spaces. The pipes connect to standard tub drain elbows, slip-joint fittings, and trap adapters to route water from the existing drain opening to the waste line.

Flexible drain pipes designed for tubs are generally 1 1/4", 1 1/2", or 1 5/8" in diameter and made of bendable ABS or PVC plastic. The flexibility comes from the material itself as well as spiral corrugations in the pipe wall which allow it to be bent and shaped by hand without kinking. Lengths range from 12" extensions to 60" runs depending on bathtub dimensions. Flexible tubing won't crack or dent when bent and holds its shape once installed.

When Should You Use a Flexible Drain Pipe?

Upgrading old or faulty tub drains to flexible piping has many advantages over using rigid piping. Consider a flexible plastic drain pipe for installations where:

• The existing drain needs replacement due to age, clogs, or damage
• The current drain pipe has developed leaks
• The drain assembly is positioned at an awkward angle
• Space is tight and access is limited
• You want an easy, DIY-friendly repair option
• ADA compliance renovations are needed

The ability to manually bend and manipulate flexible drain pipes allows them to fit connections that would be extremely difficult with traditional rigid piping. The ease of installation also makes these pipes ideal for DIY repairs.

Flexible Drain Pipe Sizing and Dimensions

Flexible tub drain pipes come in set diameters, so choosing the right size for your existing drain is crucial. Measure carefully, as an improperly sized pipe won't make the proper seals or fit the available space. Common sizes include:

• 1 1/4" - Best for shallow tub depths
• 1 1/2" - Fits most standard tub drains
• 1 5/8" - For deeper tub drain openings

Make sure to check both the inner and outer diameter of your current drain pipe. While 1 1/2" is standard, older plumbing may be slightly smaller. Flexible drain pipes can be cut to length using a hacksaw during installation. Measure the required distance from the tub drain to the trap and allow several extra inches for positioning.

Advantages of Flexible Tub Drain Pipes

Upgrading to a flexible tub drain offers many benefits over rigid piping for renovations and repairs:

• Conforms to any angle easily with hand pressure
• Saves time and frustration versus cutting and soldering pipes
• Allows simple installations even in tight, confined areas
• Can be installed without removing the tub or tile
• No pipe cutting tools, torch, or soldering skills required
• Low cost fix for refreshing old or damaged drains

The flexibility is the real game-changer. Fitting rigid pipe between misaligned or awkward connections often requires multiple elbows, couplings, and precisely measured cuts. Flexible tubing eliminates all that guesswork, allowing DIYers to route and connect drains even in cramped spaces. The result is a watertight seal without the headaches of tradition pipe rigamarole.

Step-by-Step Installation Guide

Installing a flexible tub drain pipe is a straightforward DIY project. Here are the key steps:

1. Turn off the water supply - Locate the shutoff valves for both hot and cold water lines and turn them off.
2. Remove the old drain - Unscrew the drain plate/trip lever assembly from the tub. Unseat the old drain pipe from its slip joint or threaded fittings.
3. Clean the drain opening - Use a zip-it tool to clear hair and gunk from the drain opening and existing pipe.
4. Dry fit the flexible pipe - Start with the tub end and bend the pipe to match the drain angle. Mark the length needed.
5. Cut the pipe - Add 2" to the measured length and cut the pipe with a hacksaw. Use a tubing cutter for cleaner results.
6. Attach tub fitting - Secure the flexible pipe end to the drain elbow/flange with the slip joint nut.
7. Connect to trap adapter - Bend the pipe to align with the waste line. Tighten the trap adapter nut over the flexible pipe.
8. Check for leaks - With water supply on, fill tub and check drain connections for leaks.

The key is taking things slowly and methodically - measure twice, cut once. Flexible piping allows do-overs if needed. Be sure to have a small bucket on hand to catch water in the trap when unseating old connections.

Compatible Drain Fitting Options

Connecting flexible tub drain pipes requires compatible fittings on both ends. Most hardware stores offer package deals bundling flexible pipe with two needed adapters. Choose from:

• Drain elbows - 90 degree elbows with slip-nut to secure to tub drain opening.
• Slip-joint adapters - Compression fittings that slide over pipe and tighten via rotating nut.
• Flanges/gaskets - Seal bottom drain connection to tub.
• Trap adapters - Connect flexible pipe to waste line P-trap.

Ensure all fittings match the diameter of your flexible pipe. Mixing 1 1/4" and 1 1/2" components creates leaks. Stick with name brands like Keeney, Jones Stephens, or Watco for reliability. With the right adapters, flexible tub drain pipes fit most existing assemblies.

ADA Compliance Considerations

For ADA compliant bathrooms, pay attention to drain and overflow compliance. Flexible drain pipes only meet ADA standards when used with compatible kits like the Watco PresFlo. Drains with trip levers and pop-up stoppers tend to be non-compliant, as are cable-operated tub overflows.

ADA requirements for tub drains include:

• Drain opening must resist hair clogs and allow easy cleaning
• No sharp edges or abrasive surfaces
• Drain cover must be removable without tools
• Drain trip lever (if included) must be reachable from seated position

The key is matching flexible piping with the right drain heads and overflow assemblies. Consult manufacturers to ensure chosen products meet ADA guidelines.

Common Questions About Flexible Drain Pipes

For those tackling tub drain repairs and upgrades for the first time, questions commonly arise. Here are answers to some frequently asked flexible drain pipe FAQs:

Yes, flexible drain pipes can be cut to size with a hacksaw or tubing cutter. Measure the needed length and add a couple extra inches to allow fine tuning.

No special tools needed! The flexibility of the pipes allows them to be bent by hand to fit connections. Have a bucket, hacksaw, tubing cutter, adjustable wrench, and slip-joint pliers available.

With all the right materials on hand, expect 1-3 hours for the complete flexible drain installation, including cleanup.

Yes, these pipes work for any household drain line that requires a flexible connection. Common uses include sinks, laundry tubs, and shower stalls.

Pick up a tub drain conversion kit which includes flexible piping, drain elbow, tub gasket, washers, and trap adapter. Flanges, slip nuts, PVC cement, and emery cloth may also be required.
