General description

Finishes. Heritage LCC push-fit soil and waste pipes and fittings are factory coated with a 2-pack semi-gloss paint finish, suitable for internal and external installations. All pipe also has a yellow ochre two-part internal coating.

Standards. Heritage LCC push-fit waste pipes and fittings comply with BS 416: Discharge, ventilating pipes and fittings, sand cast or spun in cast iron, Part 2. Heritage LCC push-fit systems also comply with the relevant sections of the Building Regulations throughout the United Kingdom. The synthetic rubber gaskets comply with BS EN 681-1.

Installation. BS 8000: Workmanship on building sites, Part 13, Code of practice for above ground drainage and sanitary appliances, 1989 is applicable.

Suitability. Cast iron should not be used for conveying acid wastes, or laid unprotected in any soil conditions where corrosion could occur.

On-site storage. To avoid accidental damage to collars or pipe ends, store pipes horizontally, blocked up clear of the ground and preferably under cover.

Imperial dimensions. All products are made to the original imperial dimensions. This gives a compatible interchange between old and new pipes and fittings, and makes it more likely that the original fixing holes can be re-used when an existing installation is repaired or replaced.

Pipe fixing and support. Holderbats for plugging and screwing to walls are available. Use bobbins to pack out the holderbat, to give a 32mm painting gap for pipes up to 50mm (2”) diameter and 38mm for 100mm (4”) diameter pipes. For fixing centres, refer to BS 8000: Maximum distance between sanitary pipe supports, Table 1.

Pipe joints. Make pipe joints with push-fit sockets and rubber gaskets, available in 3 versions: eared, plain and slip sockets. Fit them with the gasket relaxing tool and an appropriate lubricant.

Testing. The Building Regulations 1991, Requirement H1, Approved Document paragraph 1.7(a) requires that all pipes, fittings and joints can withstand an air or smoke test of at least 38mm gauge for 3 minutes.
