Rainwater pipes and fittings for roof drainage

Rainwater pipes and fittings help carry rainwater from roof gutter outlets into a rainwater collection or drainage layout. The products include PVC-U rain water collection pipe and matching parts for direction changes, branches, reductions, closures and mounting. They support roof rainwater pipe systems where pipe runs need to be built, extended, repaired or adapted with compatible components.

Product options include grey PVC-U pipework and fittings, plus selected support and accessory parts in PE, polycarbonate and steel. The listed parts cover common rainwater pipe fittings such as bends, T-pieces, reducer sockets, reducer bushes, caps, siphons, bracket bands, wall brackets and mounting adaptors. These components are used together to create practical rainwater drainage systems from roof level to the required collection or discharge point.

Choosing PVC rainwater pipes

PVC rainwater pipes are listed as rain water collection pipe in grey PVC-U. Available product details include plain pipe ends and glue socket x plain connections. Selected variants include 60 mm and 70 mm sizes, 1.5 mm pipe wall thickness, lengths such as 4 m and 5.55 m, and markings such as SN1 or KOMO where stated on the product title.

For rainwater collection layouts, match the pipe diameter and connection style before choosing fittings. A pipe described as plain needs fittings that suit that plain end, while glue socket connections must be paired with compatible glue connection parts. Browse rainwater collection products when the installation calls for dedicated pipe and fitting combinations for collecting roof water.

Connection styles and compatibility

Connection descriptions in the product names include glue socket, plain, spigot, insert in pipe, glue socket x spigot, glue socket x insert in pipe, and glue spigot x glue socket. These terms are important when selecting rainwater pipe connectors and downpipe fittings. A suitable connection style helps the parts fit the intended pipe section, branch or reducer without mixing incompatible ends.

Rainwater pipe systems projects often need a clear match between existing pipe size and new fitting type. Check the listed diameter, angle and connection description together. This is especially useful when replacing a bend, adding a T-piece or connecting a reducer socket to an existing pipe run.

Bends and T-pieces for roof rainwater pipe systems

Bends are used where rainwater gutter pipes or vertical pipe runs need to change direction. Listed options include PVC-U bends at 45° and 87°, with connection types such as glue socket x insert in pipe and glue socket x spigot. These fittings help route roof drainage pipes around building details and towards the required rainwater drainage pipe route.

T-pieces create a branch connection within a rainwater pipe system. The available product titles include 45°, 87° and 90° PVC-U T-pieces, with glue socket connections and insert in pipe options. A listed 90° T-piece also includes a leaf catcher and overflow 50 mm in the product title. Select the angle and connection type according to the pipe layout and the function required at that part of the system.

Reducers, caps and specialist rainwater fittings

Reducers help connect pipe sections or fittings with different diameters. The listed options include reducer sockets and reducer bushes in grey PVC-U, with connection descriptions such as glue socket x insert in pipe, glue socket x spigot and glue spigot x glue socket. Visible sizes include combinations such as 50 mm x 70 mm and 70 mm x 60 mm, depending on the product variant.

Caps and mortar caps provide closure or protection where the design calls for it. Listed products include PVC-U caps with glue socket connections and PE mortar caps in blue with glue socket connections. A PVC-U siphon with glue socket x spigot connection is also available. These PVC rainwater fittings support practical adjustments in rainwater drainage systems when pipe ends, branches or special connection points need to be completed.

Brackets and mounting parts

Rainwater drainage pipes need suitable mounting parts to keep pipe runs positioned correctly. Listed support products include PVC-U bracket bands in grey, steel wall brackets in grey and polycarbonate bracket mounting adaptors. The mounting adaptor product title includes M6, which can help when checking compatibility with the intended bracket setup.

Choose bracket bands and wall brackets according to the pipe diameter and the installation position. The product titles show multiple bracket band variants, so size matching is an important selection step. Support parts should be planned together with the pipe route, bends, T-pieces and reducers, rather than treated as a final add-on.

Practical selection for rainwater drainage systems

A reliable selection starts with the pipe diameter, then the route. Identify each change of direction, each branch, every reduction and every point that needs a cap or support. After that, match the material and connection type across all parts. For broader project planning, related drainage, sewage, tanks and rainwater systems can help align rainwater pipework with the wider water management layout.

Rainwater pipes and fittings work best when each component is chosen for the exact role in the system. Use 45° or 87° bends for direction changes, T-pieces for branches, reducers for diameter transitions, caps for closures and brackets for mounting. Careful matching of size, material and connection style keeps roof rainwater pipe systems consistent from the gutter outlet through to the rainwater collection pipework.
