Tree roots in the pipe are not the only cause of blockage. Other factors include age-related breakage, corrosion, and outside utility work. A professional should assess the damage and determine the best method for resolution of the situation. Most companies will also help with utility protection insurance policy claims. Actual prices will vary dependent on the materials used, type of soil encountered, and how deep the sewers are buried.
If you notice a foul odor in your basement that means waste water from your house is not reaching the municipal sewer line or septic tank. Additionally, pools of water near the drain or a gurgling sound in the toilet should not be ignored. Keep in mind, when the damage is in the main drain line, any water used in the household will make the problem worse.
When trenchless sewer pipe lining is the best method for repairing your sewer lines, a licensed plumber will be able to explain the process and estimated cost fully. Replacement of the complete line is sometimes recommended. Frequent repairs and patch work can end up costing homeowners more in the future.
Experienced plumbers are familiar with different type of replacements. The company will review the official sewer pipe plans for your community before starting the job. Reliable companies will provide full disclosure when discussing, sewer, gas and chemical pipelines.
Whenever possible, trenchless sewer line replacement is preferred because this technology is a much cheaper and more efficient method than using a backhoe to dig a trench. The technique also minimizes damage to the landscaping or driveways on the property. This procedure will not be used to replace pipes with significant sags or to correct grade alignment issues and improperly laid segments. Pipe bursting, also referred to as pre-chlorinated pipe bursting, and cured in place pipe (CIPP) are the current types of trenchless technology.
CIPP requires one access hole and is the most frequently used method. New joint-less, seamless pipe is inserted into the damaged pipe. CIPP handles water and air pressure lines.
Pipe bursting can employ two methods to address deteriorated or undersized pressure and non-pressure pipelines. This the best choice for the lateral pipelines that branch off to the main or transmission line and if the segment has collapsed. The first type of pipe bursting uses static methodology to control water and natural gas pressure on the pipe walls. The second, pneumatic pipe bursting, is used for gravity sewer and storm pipeline replacement. Pipe bursting requires two access holes on either side of the system.
– A flexible breaking head with hydraulic pulling power, is inserted and drawn through the pipe system.
– The pipe will fracture.
– The new pipe is pulled through using expanders to create space.
– Once the pipe is laid, then pressure tested, chlorinated, and test for bacteria are completed.
– The pipe is sealed with a (DIPS) pulling head fusion at one end and with a fused cap at the other.
– Material such as a resin-soaked felt tube or cloth made with fiberglass and other materials that facilitate resin impregnation will pulled into damaged pipes.
– To invert the liner water or air in pressure vessels, scaffolds or a Controlled Head Inversion Pressure (CHIP) unit will be used.
– To cure the resin hot water, UV lights, ambient curation or steam is used, to form a tight-fitting, joint less, and corrosion resistant pipe.
– Remote control is used for internal restoration of service laterals, the pipes that connects a property to an area’s sewer system.
– Closed-circuit television (CCTV) is used for a final inspection of the job.
– The connections are closed with a hydrophilic, water-repellant seal.
