LCC Soil Pipe Unequal Branch

The LCC unequal branch joins a smaller pipe into a cast iron soil stack, with a branch one size smaller than the main pipe. It is used where a waste or a smaller-bore connection enters a larger stack.

Using a reduced branch avoids fitting a full-size branch and a separate reducer, keeping the joint count down and the fitting compact. The branch is cast with a socket to receive the incoming pipe, in a choice of branch angles.

Unequal branches are typical where basin, bath and sink wastes join a 100mm stack, and on older buildings where the original stack collected wastes at several levels. Equal branches, branches with access doors and double branches are also available in the range.

Main pipe sizes: 65mm (2½″), 75mm (3″), 90mm (3½″), 100mm (4″) and 150mm (6″). The branch is one size smaller than the main pipe; please state the branch size you need when ordering, and we will confirm it before dispatch.

Cast iron to BS 416-1:1990, supplied with a black bitumen coating as standard. Bitumen cannot be reliably overpainted; where the stack is to be painted, ask about our Traditional Express push-fit system.
