General Description
Finishes
Harmer LCC soil & waste pipes & fittings are factory-dipped in bitumen in accordance with BS 416. Where gloss painting is required, it is advisable to contact the manufacturer.
Standards
Harmer LCC waste pipes & fittings comply with the requirements of BS 416: Discharge, ventilation pipes & fittings, sand cast or spun in cast iron, Part 1, 1990. Harmer LCC systems also comply with the relevnt sectins of the Building Regulations throughout the UK.
Installation
BS 8000: Workmanship on building sites, Part 13, Code of practice for above ground drainage & sanitary appliances, 1989 is applicable.
Suitability
Cast iron should not be sued 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, pipes should be stored horizontally, blocked up clear of the ground & preferably under cover.
Imperial Dimensions
All products are made to the orginal imperial dimensions. This ensures a compatible interchange between old & new pipes & fittings & makes it more likley that, where an exitsing installation is been repaired or replaced, the original fixing holes can be re-used.
Pipe Fixing & Support
Holderbats for plugging & screwing to walls are available. Bobbins should be used to pack out the holderbat to give a 32mm painting gap for pipes up to 75mm (3") diameter, & 38mm for the 88mm (3 1/2") & 100mm (4") diameter pipes. For fixing centres reference should be made to BS 8000: Maximum distance between sanitary pipe supports, Table 1.
Pipe Joints
Pipe joints should be made using a caulking of 6mm diameter yarn, now available only in glass fibre instead of the traditional tarred yarn, with a minimum 38mm thickness of lead wool, wel compacted.
Testing
The building regulations 1991, Requirement H1, Approved Document paragraph 1.7(a) requires that all the pipes, fittings & joints should be capable of withstanding an air or smoke test of at least 38mm gauge, for 3 minutes.
