Fix Misaligned PVC Pipes with 90-Degree Fittings

The Parallel Pipe Solution

When two PVC pipe ends are misaligned but can be bent to run parallel to each other, two 90-degree fittings offer a simple and effective repair. Instead of forcing the pipes to meet or using expensive telescoping couplings, this method creates a clean connection that handles the offset naturally.

• No Stress on Pipes: The 90-degree turns accommodate the offset without forcing bends
• Permanent Fix: Cemented joints are as strong as the original pipe
• Inexpensive: Two 90-degree fittings cost just a few dollars
• Versatile: Works for both horizontal and vertical offsets

Why Two 90-Degree Fittings?

When pipes are offset but can be bent to run parallel, two 90-degree fittings create a simple connection:

• U-Shape or S-Shape: Two 90s form a path that bridges parallel pipes
• Adjustable Spacing: The length of pipe between the fittings determines how far apart the parallel pipes can be
• Clean Turns: 90-degree angles provide a professional, organized look
• Better Than Forcing: Eliminates stress that comes from bending pipes to meet

90-Degree vs 45-Degree Fittings

Both can solve misalignment, but they work differently:

Use 90-Degree Fittings When:

• Pipes can be bent to run parallel to each other
• You need to create a U-turn or sharp offset
• The offset is significant and requires a defined path change

Use 45-Degree Fittings When:

• Pipes are nearly aligned but just offset slightly
• You want a gradual direction change
• Flow efficiency is critical (45s cause less turbulence)

1 Assess the Misalignment

Before cutting anything, understand your situation:

• Can the pipes be gently bent to run parallel?
• Measure the distance between the pipe centerlines when parallel
• Note if there's vertical offset in addition to horizontal
• Make sure you have enough pipe length to work with on both ends

2 Prepare the Pipe Ends

1. Cut the existing pipes to create clean, square ends
2. Remove any damaged sections
3. Clean debris from inside and outside the pipe ends
4. Make sure the pipes are dry before cementing

Leave enough length on both pipes to accept the 90-degree fittings.

3 Build the Connector Assembly

Create your 90-degree connector before installation:

1. Cut a short pipe section to connect the two 90-degree fittings
2. The length determines how far apart the parallel pipes can be
3. Dry-fit everything first to confirm measurements
4. Mark the orientation of each fitting with a marker

4 Dry-Fit the Complete Assembly

Test everything before using cement:

1. Position the pipes parallel to each other
2. Insert your pre-built 90-degree assembly
3. Check that everything fits without stress or forcing
4. Adjust pipe lengths or connector length if needed
5. Mark all positions with a marker for reference

5 Apply Primer and Cement

Work one joint at a time:

1. Apply purple primer to the first pipe end and inside the fitting
2. Apply PVC cement to both primed surfaces
3. Push the fitting onto the pipe with a quarter turn
4. Hold for 30 seconds
5. Repeat for the second pipe connection

6 Cure and Test

Allow proper cure time before pressurizing:

• Initial set: 2 minutes - don't move the joints
• Handling: 15-30 minutes
• Pressure test: Wait at least 2 hours
• Best practice: 24 hours for full cure

Turn on water slowly and inspect all joints for leaks before backfilling.

When to Use 90-Degree Fittings

• Parallel offset pipes: When pipes can be bent to run in the same direction
• Significant height differences: When one pipe is much higher than the other
• Obstacle routing: When you need to go around a rock, root, or other obstruction
• Clean appearance: When you want organized, professional-looking turns
• Valve box connections: Creating organized pipe runs into valve assemblies

Common Mistakes to Avoid

• Not dry-fitting first: Always test the assembly before cementing
• Wrong method choice: If pipes point toward each other (not parallel), use 45s instead
• Connector too short: Make sure the pipe between 90s is long enough for your offset
• Forgetting to mark positions: Mark fitting orientations during dry-fit
• Rushing the cement: You have seconds to position fittings correctly
• Wet pipes: Cement won't bond to wet surfaces - dry everything first
