Corrosion eats away pipe cause pitting and thinning of pipe walls. But since the corrosion happens inside the pipes, they are not easily detected. Some symptoms of damaged pipes include low water pressure, discolored water coming out of your faucets, and leaks. When you get leaks that usually means pinholes have already eaten all the way through pipe walls or there are cracks in the pipe. These signs may point to localized pipe failures or one that affects the whole system. When pipes in old buildings begin to fail many people make the mistake of just deciding to get the pipes replaced. Replacing a home’s pipes can be very costly. It will also usually involve a lot of tearing out of walls, as well as excavating yards and gardens just to get access to the pipes being replaced. And after the pipes are finally replaced, there remain expensive restoration work; putting back walls and repairing affected paint sections, restoring and replanting on disturbed garden areas, maybe even repairing affected concrete and tiles in some areas. So many homeowners never even consider pipe lining Toronto, rather than tearing up and replacing old pipes. And that is something that may end up having required repairs cost more than it should. But that is not to say that all old piping can be saved by pipe lining in Toronto. Only inspection would reveal whether the pipes have sufficient strength and wall thickness to be saved using pipe lining techniques. Usual methods of inspection are miniature CCTV cameras and bore scopes. Many companies who provide plumbing services now offer pipe lining installation as an option. The many advantages of having old but still structurally sound piping repaired using pipe lining technology include: a) Cost savings: Even if the cost of pipe liner installation would approximate the cost of pipe replacement, major savings can be realized due to the non-invasive and trenchless nature of the repair technique. Restoration and clean-up costs can be kept to a bare minimum. Plumbing services cost using pipe liners is therefore much less. b) Better quality: Even if pipes were replaced using copper materials, these are still subject to corrosion, and thus cause a mild bit of water contamination as well. Epoxy pipe liners do not corrode and have been approved for use on potable water systems, some have even been approved for use on hot water systems. c) Tighter pipe system: Installation of epoxy pipe lining eliminates joints and seams; the only joints or seams are the two ends of pipe liners. This makes the pipe system less likely to spring leaks. d) Less downtime: Licensed plumbers can install pipe liners much faster than an equivalent length of pipe replacement. That not only means savings on labor cost, it drastically reduces downtime. It must be stressed, however, that not all epoxy lining systems are the same; some systems perform better than the rest and differ in the approvals they have obtained from testing agencies. It would therefore be wise to ask for some advice from trade associations such as the Canadian Institute of Plumbing & Heating before making a decision.
