4" Wye Fitting for Corrugated Drainage Pipe

Create a more efficient drainage layout with this 4" Wye Fitting for Corrugated Drainage Pipe. Unlike a 90-degree tee, a wye fitting joins pipe runs at a gradual angle, making it a practical choice for merging two drainage lines into one main run.

Use it for French drains, downspout drain lines, catch basin systems, and other underground drainage projects where water from multiple areas needs to flow toward one outlet. Pair it with compatible 4-inch corrugated pipe, couplers, elbows, and adapters to build a complete drainage system for your landscape.

FAQs

What is a wye fitting used for?
A wye fitting connects two drainage runs at an angle and directs them into one main pipe run.

What is the difference between a tee and a wye fitting?
A tee creates a 90-degree branch connection. A wye fitting uses a gradual angle, which is generally better when combining flowing water from two pipe runs.

Can I use this to combine downspout drainage lines?
Yes. It can be used to merge compatible downspout drainage lines into one larger run, provided the system is properly sloped and sized for the amount of water being handled.

Will it work with solid or perforated pipe?
It is designed for compatible 4-inch corrugated drainage pipe. Confirm the connection style before ordering, particularly if joining different pipe types or brands.

Do you deliver drainage supplies?
Yes. We offer flatbed delivery throughout Metro Atlanta, including Roswell, Alpharetta, Johns Creek, Suwanee, Duluth, Milton, and surrounding areas.
