Plumbing systems in residential and commercial property usually deteriorate with time. This leads to leaks, rust accumulation, and degradation of both water and sewer pipes. As a result, water flow is impeded, and drinking water may be contaminated. However, Trenchless sewer pipe lining system offers a permanent solution to such plumbing complications. The method uses a special lining to create a pipe within a pipe.
With Trenchless, property owners in Mesa, AZ, now have a cost effective and less invasive means of repairing sewer pipes.
Below is a systematic procedure of applying sewer pipelining:
Step 1: Location of the pipes
The first phase involves locating pipes that need lining. The pipes are usually buried deep beneath the ground and require a certified technician to locate. Location of the pipes may be done using special equipment, above ground fittings, building drawings, and plans.
Step 2: Isolation and disconnection
Once the pipes are located, a certified technician must first shut off water that flows into the pipes before rehabilitation. The appropriate valves within the system are isolated and closed so that only the specified pipes are shut off. This ensures that only those isolated for lining are affected while normal water supply continues in the rest of the system.
Step 3: Drying of pipes
The pipes are dried by passing pressurized hot air from a compressor.
Step 4: Cleaning of pipes
The pipes are cleaned to remove corrosion and other unwanted coatings that may hinder water flow and affect the quality of the water. Cleaning of the interiors also prepares the internal surface of the pipes for bonding with the special lining to be used. Before cleaning, every section of the pipe that forms an access point is detached from the main unit. The most common cleaning method is sandblasting by means of specialized cleaning particles. Other methods include power boring, drag scraping, pressure scrapping, high-pressure jetting, and wire brushing. Chemical cleaning may also be used if necessary. Whichever method of cleaning is used, the aim is to attain a sound clean surface that will enhance proper bonding between the lining and the pipe’s interior surface.
Step 5: Pre-lining inspection
Before applying the pipe lining, a Closed Circuit Television (CCTV) inspection is carried out to identify any complications remaining inside the pipe after cleaning. The inspection also reveals if the pipe is properly cleaned.
Step 6: Application of pipe lining
The Trenchless lining is applied to protect the pipe against corrosion and leakage. A special hose attached to a rig passes through the pipe to be lined. A spray head is attached to the hosepipe at the far end of the pipe. Once the rig is turned on, a specially formulated coating is blown through the pipe, creating a protective barrier within the interior surface. The rig has a computerized metering system that determines the thickness needed for the lining.
Step 7: Curing
The pipe is sealed and allowed to cure for a minimum of 5 hours.
Step 8: New fixture and post-lining inspection
If proper curing time is fully observed, the pipe is ready for inspection at this point. A CCTV inspection is conducted again to ensure that the lining is completely and evenly applied. New fixture valves are then installed and the pipe tested. The testing should reveal if the pipe can carry water safely without any leakage. It also ensures that water pressure is restored to normalcy.
Step 9: Disinfecting the pipes
To ensure that the water is safe for use, the pipe is disinfected by chlorination to remove any impurities.
Step 10: Reconnecting and water restoration
Finally, the lined pipe is reconnected and water restored for service.
If you have a leaking or clogged sewer line or battling a serious rust intrusion, Trenchless sewer pipe lining offers a permanent solution. It restores the structural integrity of the sewer pipe, creating a new pipe that will last for decades.
