Rectangular Pipe to Round Connector

£160.61 – £240.02Price range: £160.61 through £240.02 +VAT

Clear

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.

Why should I choose cast iron for my rainwater system?

Why should I choose cast iron for my rainwater system?

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

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.
