The Rectangular Pipe to Round Connector provides a transition fitting between a cast iron rectangular downpipe and a cast iron round downpipe, allowing the two pipe systems to be joined cleanly in a single run. Used where a rectangular pipe at the upper part of the elevation transitions to a round pipe — for example where the rectangular section connects to a round underground drainage system, or where an existing round pipe is being connected to a new rectangular installation above.
An important practical fitting on heritage restoration projects where the existing above-ground pipe is rectangular and the below-ground or transition pipework is round. Manufactured in cast iron to BS 460:2002. Available in sizes to suit the standard rectangular pipe range. For specification support, call 0333 987 4452.

Yes. Cast iron hopper heads are the historically correct choice for listed and period buildings, and a like-for-like cast iron replacement is generally accepted without objection by conservation officers. We manufacture to BS 460 for genuine heritage character and durability.

Casting of iron is an imperfect processs. It is possible with some cast iron radiators that you will get minor imperfections in the surface finish. When radiators are painted this will reduce and over the years every additional coat of paint applied will provide a smoother more equal finish.
Yes — we strongly recommend painting all products before installation to ensure full coverage on every surface, which reduces long-term maintenance. Standard Premier Rainwater products are supplied in a grey metal primer with rust inhibitors and need two undercoats and one top coat (or one undercoat and two top coats) of a good quality exterior paint.
The Pultney Tapered Hopper Head is available in three pipe connection sizes: 65mm (2.5"), 75mm (3"), and 100mm (4"). Each size connects directly to matching cast iron downpipes via spigot and socket. Compatible downpipe codes are: 65mm — RH025, XRH025; 75mm — RH03, XRH03; 100mm — RH04, XRH04.
For rooflights directly above a worktop or sink, a telescopic screw-jack hand winder is the most practical choice. Available in polished brass, satin chrome, and polished chrome, these openers allow controlled ventilation from a fixed handle position without requiring a pole. The 150mm or 250mm size is typically appropriate for standard-height kitchen rooflights.

Yes. The ornamental foliate pattern was widely used in Victorian construction and is appropriate for Grade II listed buildings and conservation area properties. Its decorative character is often preferable to a plain pattern on prominent or formal elevations. We recommend confirming the pattern with your conservation officer as part of any listed building consent application.
