Do I need to use primer with PVC cement?

Yes, purple primer is required by most plumbing codes. Primer softens the PVC surface for a stronger chemical bond. Some all-in-one cements include primer but may not meet all code requirements.

What is the difference between a tee and a wye fitting?

A tee creates a 90-degree branch. A wye creates a 45-degree branch, which is preferred for drain lines because it provides smoother flow direction changes.

Code Requirements

Must meet ASTM D2665 for DWV fittings. Long-sweep elbows required for drain applications. Proper slope maintained through fitting selection. Cleanout fittings required per code at specified intervals.

Buying Tips

Buy an assortment of common fittings before starting your project. Long-sweep elbows are required for drain lines. Always dry-fit the entire assembly before cementing anything. Keep extra fittings on hand for mistakes.
