Can cast iron soil pipe be used in any type of building classification?
- Yes. Cast iron is non-combustible and therefore has no restrictions as to the type of building it can be used in. Cast iron does not burn and doesn't give off toxic fumes or produce clouds of black smoke when subjected to heat. The same cannot be said for plastics as they are combustible and have many restrictions placed on the within the building code.
Do cast iron pipes rust?
- Cast iron has unique corrosion resistant characteristics. When cast iron is exposed to corrosion, the corrosion actually leaves behind an insoluble layer of corrosion products which actually provide somewhat of a barrier against further corrosion. To find out the effects of specific chemicals or solutions, please contact your sales representative and they will provide you with the information you require.
How long can you expect a cast iron system to last in a building?
- Cast iron will usually outlast the life of the building. Cast iron has been in use for centuries. One of the first installations was in Versailles, France in 1664 to carry water some 15 miles to the palace and surrounding area. This system is still functioning after 300 years of service.
I use a combination of cast iron and copper on my installation, how do I reduce my cost?
- Instead of using copper, which is used on the 2" and 1-1/2" pipe mostly, use 2" and 1-1/2" cast iron pipe. Not only is the cast iron less expensive in almost every case, more importantly, it reduces your cost on purchasing the tools required to install copper pipe. Cast iron is faster and easier to install. For more information on 2" and 1-1/2" pipe and fittings please visit the catalogue section of our web site.
Is cast iron quieter than other DWV materials?
- Yes. Test recently conducted in the Domtar Acoustical Laboratories by MJM Acoustical Consultants Inc. prove that cast iron is quieter. For a complete copy of this report, contact the Cast Iron Soil Pipe Association at 1-519-621-8141.
Waterworks and municipal
What's the difference between airtight and water-tight covers?
Water-tight : means that the frame has a gasket and four bolts or more in order to prevent infiltration.
Airtight : means that by inserting a rubber o' ring between the cover and the frame, we reduce odors (cover's weight, even with a rubber o' ring, is not enough to make a cover airtight).
