Introduction to Pipe Relining

Pipe relining is a trenchless technique for repairing damaged pipes without excavation. It involves feeding a resin-saturated liner into the existing pipe and curing it in place to form a smooth, jointless “pipe within a pipe”.

Pipe relining helps prevent blockages by stopping grease and food buildup.

The smooth interior surface created by relining prevents waste cling and buildup, while also restoring flow capacity allowing waste to pass through with ease. The liner also restores flow capacity, allowing waste to easily pass through instead of getting stuck.

Your local Coogee Plumbing, with over a decade of expertise in Coogee and the North Shore, Sydney, offers advanced relining services to effectively prevent blocked drains. Our solutions, including pipe lining, effectively counteract grease and food buildup in kitchen sinks, bathroom pipes, or sewer drains.

Causes of Grease and Food Buildup in Pipes

Several common causes blocked drains experience originate from grease and food buildup inside pipes:

  • Cooking oil and fats - Items like vegetable oil, butter, lard, and meat fats are prone to clinging to pipe walls, hence accumulating over time.
  • Scraps of toilet paper and food flushed down toilet can get stuck, decompose, and initiate clogs.
  • Baking ingredients - Substances such as flour, sugar, dough, batter, and baking soda can stick together inside a drain pipe.
  • Sauces and dressings - Thick, sticky sauces often contain fats, eggs, and starch which can coat pipes.
  • Sanitary products including milk, cream, cheese, and yoghourt tend to leave fatty residues as they spoil.
  • Cat litter and soap scum find their way into forming residues, with most soaps containing fat that leaves a stubborn film on pipe walls.

As these substances find their way down the pipes, they tend to accumulate on any present cracks, joints, or imperfections. Fats and oils then solidify while food particles decompose. The build up worsens as more waste flows through, which can cause an eventual blockage of water flow.

Fats, oils, and grease contribute to the deterioration of older pipe systems by causing buildup. This leads to more cracks for the waste to accumulate inside, necessitating repairs or relining.

How Pipe Relining Prevents Future Buildup

Pipe relining serves as a preventative measure against future buildup by creating a new seamless pipe within the existing one. The process involves inserting a resin-saturated liner into the damaged pipe and curing it in place with hot water or steam.

As the liner cures, it forms a smooth, seamless new pipe wall that prevents areas where debris could become blocked, thus clearing drain challenges as it matches strength and durability of traditional piping. This smooth surface ensures waste won’t cling to cracks or joints within home piping, preventing the deterioration seen in older pipes. Instead, food particles and oils grease can easily slide through the relined pipe without sticking.

Relining restores flow capacity so waste can efficiently drain from sinks, maintaining optimal flow rates. No matter the consistency, it protects against blockages in your sink drain, buildup, and backups by giving debris no place to accumulate inside. Considering how much kitchens and bathroom sink areas are used, this makes relining an ideal preventative solution for both residential and commercial spaces.

Examples of pipe relining as a preventative measure, besides the use of tools like a DIY drain snake, include:

  • Kitchen drain lines prone to grease buildup
  • Sewer pipes susceptible to invading tree root systems
  • Pipe sections with persistent clogs and blockages, particularly affecting stormwater drains systems
  • Old clay pipes showing signs of wear and damage

In cases where pipe damage is already causing backups and overflows, our team can apply relining to fix current issues and prevent the same problems recurring. Engage with our team at Coogee Plumbing today to discover how our pipe relining expertise can effectively deal with drains blocked by various obstructions.

Proper Maintenance Post-Relining

We provide expert advice to ensure pipes remain free from clogs after relining, as ongoing maintenance is crucial. Here are some tips:

  • Avoid flushing baby wipes and pouring fats oils down your drains; these items solidify and cling to pipes, so discard them in the trash instead.
  • Use sink strainers - Strainers catch food scraps and foreign objects so they don’t head down pipes.
  • Utilise a baking soda vinegar combination - an effective concoction that breaks up grease and clears residue buildup.
  • Regularly send water down drain pipes with high pressure - Boiling water dissolves fats. Pour down sinks regularly.
  • Don’t use commercial caustic cleaners - Harsh chemicals damage pipes over time.

It’s essential for commercial kitchens to maintain grease traps in accordance with local regulations to prevent blockages and ensure proper wastewater management.

It’s worthwhile to consider natural drain cleaner alternatives such as enzyme treatments and microbial blocks that help break down waste between comprehensive cleanings.

Alternative Prevention Methods

Aside from pipe relining, there are various effective methods to prevent grease and food buildup inside pipes:

Install Grease Traps

Grease traps are plumbing fixtures designed to intercept oils, fats, and solids before they enter your sewer drain in your plumbing system.

They are commonly installed under sinks and drain lines in commercial kitchens, where pipe patching may also be necessary for repairs. Grease gets trapped while water flows on through, preventing blockages down the line. If considering a grease trap, consult our blocked drain plumbers to install one properly sized for your needs.

Proper Waste Disposal

Consulting a professional plumber can fine-tune your waste disposal habits, ensuring correct disposal of oil and food waste to prevent clogs. Always collect in suitable containers and dispose in the general rubbish instead.

Prevent blockages by ensuring no fats, oils, or scraps travel down sink drains. This keeps drains clear while also minimising odours.

Natural Cleaning Remedies

You can use things like baking soda and vinegar or enzyme cleaners to regularly flush pipes and breakdown waste buildups before major blockages occur. For optimal results, we recommend cleaning your pipes every 1-2 months using these natural remedies.

CCTV Inspections

Having a drain inspection with a cctv drain camera every 6-12 months enables early detection of cracks, leaks and small accumulations. This proactive approach allows for timely drain repairs before leading to major backups or overflows down the track.

Contact our qualified plumber at Coogee Plumbing to discuss what you need know about the most suitable prevention options for your home or business pipes.

Recognizing Signs of Pipe Buildup

There are a few key signs that indicate grease, food scraps, and other debris is building up inside your pipes:

  • Slow draining sinks, tubs, or showers
  • Gurgling sounds from pipes or drains
  • Foul sewage odours, especially from floor drains
  • Wet spots or overflows around drains
  • Frequent clogs requiring drain cleaning

Drain problems, issues like accumulations clinging to pipe walls, narrowing their diameter, often result in blocked drains. Small clogs then get stuck, catching all subsequent waste behind them.

Leftover fats, oil grease, and scraps are the usual culprits. Over time, small amounts passing through the pipes leave fatty residues on the walls that solidify and can cause blockage. Meanwhile, tiny food bits decompose inside the pipes.

As buildup gets worse, a severe blocked drain can cause the water to struggle to break down and drain at a normal pace. Air also gets trapped, which can lead to gurgling sounds as waste tries squeezing past clogs. Foul sewer gases then back up through drain openings.

Recognising early warning signs of issues inside your drains allows for timely intervention to address pipe buildup before major blockages occur. Simple DIY efforts may dislodge small clogs while considerable accumulations often necessitate our professional hydro jetting or pipe relining solutions.

Contact our team at Coogee Plumbing for expert blocked drain services if you notice any signs of pipe blockages, and we will take care of the rest. We have advanced capabilities to clear built-up grease, restore flow capacity, and prevent future drainage issues.

Pipe relining is a proven trenchless method that hinders grease and food from accumulating inside pipes. By installing a smooth, jointless lining inside damaged pipes, waste is unable to cling to cracks and accumulate over time, preventing a blocked drain. Relining restores flow capacity and protects against further corrosion and blockages.

Proper maintenance is still essential post-relining, which includes ensuring each drain can effectively eliminate water with the disposal of fats/oils down drain strainers and routine cleaning with baking soda or vinegar. For commercial kitchens, proper grease trap maintenance is critical.

Understanding prevention techniques, such as CCTV inspections, and recognizing early signs of blockage can thwart severe blockages. And if grease/food buildup has infiltrated into your pipes causing drainage issues, Coogee Plumbing has professional hydro jetting and relining solutions to clear pipes and prevent recurrent problems.

Don’t wait for sewage backups or overflowing pipes to occur before taking action. Contact our team today on 1300 349 338 if you notice gurgling or slow drains so we can inspect pipes and restore proper function to all your drainage requirements before major damages occur.
