Even the best sewer pipe doesn't remain intact forever. Roots work their way in, extreme temperature changes burst pipes, and overall wear and tear compromises the constitution of older lines. It could turn out that your property will stay standing longer than the fortitude of your sewer pipe, and that means at some juncture you will need to call a contracter.
Cast iron was previously the gold standard in plumbing pipes, including the lateral sewer line, which is the drain from your house into the sewer main. When this pipe breaks, often the most prudent option is to replace the existing pipe with new ABS pipe that will not face the same risk in the future.
Another contemporary sewer pipe replacement method is called trenchless plumbing. This method makes it possible to repair the sewer pipe without tearing up your yard. One kind of trenchless sewer pipe repair is called the "bursting method": Contracters will thread a new pipeline through the existing, broken line. This further expands the old pipeline to make room for the new one.
Another trenchless sewer pipeline repair method is the "lining method." Using this strategy, plumbers will insert a plastic tube through the broken sewer pipe and inflate it. This lining will then make any cracks in the existing pipe totally moot. Better still, the lining can easily be taken out and repaired (or switched out) when future problems arise.
Even with trenchless sewer pipe repair, it is possible for invasive roots to repeat their invasion. In addition to fixing the desctruction in the pipe, plumbers may consider blocking root growth toward the line for any nearby trees.
The cost of sewer pipe repair significantly changes depending on the company doing the work and how much work there is to do. Some sewer pipes run under garages, driveways, or landscaping. Especially under such circumstances, trenchless replacement can be a preferable option. When choosing a plumber, request estimates from 2 or 3 different companies. Make sure all of the estimates include exactly the same work. Contractors often charge significantly different prices for similar labor. Also make sure you get in writing the agreed-upon state of your property once the work is all done. In other words, if a plumber does have to dig a trench in your lawn or necessitate other cleanup work, it should be clear whose job it is -- yours or theirs -- to get everything looking good again.
Whenever you request a price quote for a sewer repair, get an idea of whether it's likely more fixes will have to be have to be performed in the very near future. Especially beneath older homes (or newer homes connecting to an older sewer pipeline), it might be worth initiating an entire replacement project instead of band-aid-style fixes, so that you won't have to put up with a similar crisis 3 years from now. A lot of plumbing contracters such as sewer drain cleaning Tacoma WA offer a warranty on sewer pipe replacement, some of them for as long as you own the house.
