RELS Landscaping offers the IPEX SDR-21 1.5″ pipe for medium-capacity irrigation or drainage lines. With a larger inside diameter, the 1.5″ version supports greater flow while maintaining SDR-21’s thinner wall advantage. It’s suitable for mainline segments or branches in more extensive landscape systems.

This pipe balances cost and capacity, ideal for systems where full Schedule 40 might be overkill but standard wall thickness is too heavy. In the Maryland and Washington, DC area, the 1.5″ SDR-21 is a versatile choice for moderate flow applications like lateral mains or shared runouts.
