Tapers are purpose-built elements used to link pipes of different sizes in drainage networks.

When drainage systems are expanded, tapers deliver a more stable solution than forcing mismatched pipes together. https://fernandoqtrqo.blogkoo.com/h1-a-closer-look-at-tapers-and-taper-bends-in-drainage-usage-fitting-accuracy-and-supply-h1-57377792
