Questions about this item

Will this 2-inch hub connect to my existing Schedule 40 PVC pipe?

Yes, the fitting is Schedule 40 and the hub accepts 2-inch PVC pipe for solvent-weld joining.

Can I use this street elbow with older ABS drain lines?

No, this is PVC material; joining to ABS requires a transition coupling approved for that combination.

How do I confirm the joint is watertight after solvent welding?

Pressurise the system with water and inspect the hub and spigot connections for leaks.
