Elegance cast iron effect rainwater system.


The elegance cast iron effect range is supplied ready to fit without the need for painting or protective coatings. It is quick to install, reducing total installation cost (no metal primer, spanners, paint or disc cutters required) and does not require additional lifting aids like traditional cast iron systems as it is of lightweight construction for easy handling, assembly and installation. 


With a durable and long-lasting finish there is no need to apply corrosion control traditionally used with cast iron systems and as the Elegance products are UV stabilised to protect against colour fade you will not have to paint them to keep their colour true. 

By selecting the Elegance range you will have lower installation, product and maintenance costs and more flexibility as a wide range of roof structure design solutions can be achieved. 

The Elegance range of products is suitable for both new build and residential renovation project.

Why use plastic above ground plumbing?


Plastic plumbing components offer a wide range of advantages compared to traditional materials such as copper and is easier to install. 
In terms of ease of installation, plastic fittings and sections make the job easier at every turn with easy cutting; push fit joints and superb flexibility and handling qualities making every installation quicker. And with no welding or soldering required, they make the job safer too.


With plastic plumbing there is less potential for leaks as plastic pipes are usually available in longer lengths than copper, plastic pipes are available in lengths up to 12m, fewer joints are required along the pipeline. Plus, push fit joints can provide equal if not better integrity than traditional ones as well as being far quicker to install.

The Environmental benefits; due to this lighter weight nature, plastic pipes and fittings help to reduce energy use and therefore greenhouse gas emissions. What’s more, all products are 100% recyclable at the end of their useful life.


One of the main attractions of plastic above ground plumbing is that you can achieve the traditional cast iron look without the hassle! 
For rainwater systems, using cast iron effect pipes and gutters ensures all the benefits of quick and easy installation versus traditional cast iron systems – but with all the performance criteria you would expect from high performance, engineered plastics.

With copper theft an ever-growing problem on site due to high scrap value, PVCu and other types of plastic offer a far less tempting prospect for thieves reducing the chance of theft. So even though it’s easy to lift, it’s a lot less likely to get lifted.
