What is European Standard EN997:2003
The current European Standard relating to WC’s is BS EN 997:2003 (WC pans and WC suites with integral trap). This standard has the status of a British Standard. EN997:2003 outlines the requirements for WCs from the perspective of construction and
performance, emphasising functional criteria. Two classes of WC are identified within the standard. Class 1 covers suites for sale in mainland Europe, and a number of the tests are different from the UK requirements. Class 2 covers WCs sold in the UK.
Specific flush volumes are listed for the two classes of WC and are summarised as follows:
• Class 1 - A nominal flush volume of four, five, six, seven or nine litres.
• Class 2 - A maximum flush volume of six litres for single flush WCs. A maximum flush volume of six litres and a reduced flush no greater than two-thirds of this volume for dual-flush WCs.

Horizontal outlet (HO), what does it mean? What are the features and benefits?
Horizontal Outlet describes the angle (horizontal) at which the outlet pipe leaves the back of the WC pan. It enables easier fixing of plastic outlet pipes and is adaptable/more flexible as the pipe work can be positioned in a variety of different ways, depending on the space available, the location of the soil stack and the position of the WC in relation to the external wall. This gives the builder and the customer greater choice in where to put the toilet.

P traps and S traps - what does it mean? What’s the difference?
P and S simply describe the shape of the trap. In general, an ‘S’ trap goes out through the floor and a ‘P’ trap through the back wall.

What is IO (internal overflow) and how does it work?
Overflow pipes were traditionally positioned so that any water leaking from a cistern could escape by dripping onto the floor or outside the building. This was a requirement under UK Water Byelaws to prevent waste of water: the principle was that a dripping overflow pipe was more likely to be noticed and the problem rectified. Internal Overflow is a system that allows any overflowing water from the cistern to be discharged into the toilet bowl. It is now allowed under Water Regulations January 2001.

People weight - what weights will a particular toilet take?
32 stones. 448 pounds
