Cast iron connector from 100x75mm to 150x100mm rectangular downpipe to 65mm, 75mm or 100mm round, in primer or black painted finish.

The Rectangular Pipe to Round Connector changes a rectangular downpipe to a round section, for connection to a round pipe, a round gully inlet or an underground drain socket.

It is used at the foot of a run where the below-ground drainage takes a round pipe, or where a rectangular run must join an existing round system.

Round outlets are 65mm, 75mm or 100mm. The 100mm round outlet is not made for 125mm x 70mm pipe.

All fittings in our rectangular range are cast iron to BS 460:2002, made to the same moulded profile so pipes and fittings line up neatly on the elevation. Every fitting is supplied either in primer, ready for painting on site, or in factory black. For listed buildings and conservation areas we also offer hand-applied linseed oil paint in heritage colours, which stays breathable and flexible and is straightforward to maintain. Stocked items are usually dispatched within 5 to 7 working days; allow around 6 to 7 weeks where a linseed oil finish is specified.

Rectangular pipe sizes: 100mm x 75mm (4″ x 3″), 125mm x 70mm, 125mm x 100mm (5″ x 4″) and 150mm x 100mm (6″ x 4″).

Suitable for listed buildings, conservation areas and heritage restoration. For specification support or a project quotation, call 0333 987 4452.

Do cast iron radiators work with heat pumps?

Do cast iron radiators work with heat pumps?

Yes, provided they are sized for the lower water temperature. Outputs are published at ΔT50; at ΔT30 a section gives about half that, so heat pump systems usually need more sections or a deeper pattern. We can prepare a radiator schedule at your heat pump design temperature.

How does the ornamental pattern affect ventilation performance?

How does the ornamental pattern affect ventilation performance?

The Gothic foliate tracery design of the Ornamental Airbrick provides a good free-flow ventilation area relative to its face size. The open area is comparable to other standard cast iron airbrick patterns. The visual density of the pattern at a distance reads as solid ironwork, which suits formal and decorative elevations without compromising subfloor ventilation effectiveness.

Do other materials offer the same benefits as cast iron?

Do other materials offer the same benefits as cast iron?

The drainage and guttering market has matured considerably over the past 20 years and there are now many more product choices for consumers to consider.

Despite the influx of new materials it appears that the benchmark for rainwater systems is still cast iron. Cast iron rainwater goods were introduced in the late 18th Century as an alternative to lead. As well as being easier to produce, the material enabled eaves gutters to be installed more simply, since lead could only be used in this location as a lining for timber gutters.

Many modern materials focus on replicating the appearance of cast iron but those materials can vary rarely offer any of the benefits. Cast iron gutters and pipes offer great strength and durability, a proven history of long life, low noise operation and fire resistance. Most old buildings have cast iron rainwater systems that should be maintained and preserved however; these inherent benefits make cast iron an ideal choice for both traditional and modern installations.

It is not uncommon to see modern alternative products marketed with terms like low maintenance or easy to install and cost effective. It has even been said that ‘plastic guttering systems provide a way of achieving a traditional look with modern convenience’. These terms tend to refer to possible cost savings rather than any real product benefits. It is also difficult to quantify the benefits of modern convenience over traditional build quality.

It is worth remembering that all rainwater goods will require some element of maintaining to ensure they are unblocked by debris and remain functional. No rainwater system cleans itself. Today most suppliers of cast iron rainwater systems offer products in both primer or pre-painted with a 10 year protective coating. When describing modern materials, the term ‘cost effective’ is used rather than simply saying cheap. There is no doubt that the initial cost of many modern materials is less than cast iron but you might be surprised to know that over its lifespan, cast iron will cost around a third of plastic.

It is easy to forget about your rainwater system but it does need to be maintained and inspected at least twice a year regardless of the product material. It does not matter whether the property is hundreds of years old or brand new, the message is the same; ‘maintaining your rainwater system contributes to the external appearance of the building as well as keeping it free from damp and structural damage.

Are hit and miss vents suitable for listed buildings?

Are hit and miss vents suitable for listed buildings?

Yes. Decorative cast iron and brass ventilation grilles of this pattern were widely used in Victorian and Edwardian buildings, and like-for-like replacements are generally accepted by conservation officers for listed building works. We can provide product specifications and material details to support listed building consent applications if required.

What cast iron gutter profile do I need for a Georgian property?

What cast iron gutter profile do I need for a Georgian property?
