Old pipes can cause serious problems in the home. Over time, pipes become worn and run the risk of bursting or leaking.

It is essential to overhaul the pipes every 25 years to avoid serious damage and high costs.

Many houses in Lisbon still have pipes made of old materials such as lead or galvanized steel. These materials can contaminate water and affect health. Replacing them with modern pipes guarantees clean and safe water.

Rehabilitating old pipes is an investment that brings many benefits. As well as preventing leaks and infiltrations, it improves water pressure and prevents frequent blockages.

We can assess the condition of your pipes and recommend the best solutions for your case.

Pipe Condition Assessment

Assessing the condition of pipes is crucial to maintaining the integrity of hydraulic systems.

This process involves identifying common problems and implementing effective inspection techniques.

Identifying Leaks and Infiltrations

Leaks and infiltrations are serious problems in old pipes. They can cause structural damage and waste water.

Common signs include damp patches on the walls, a musty smell and abnormally high water bills.

To detect hidden leaks, we use advanced equipment such as thermal cameras and acoustic detectors.

These tools allow us to locate problems without causing damage to structures.

We recommend a professional inspection at the slightest sign of a leak in Lisbon.

Impact of Corrosion and Fouling

Corrosion and scale are silent enemies of pipes. Corrosion mainly affects galvanized iron pipes, while scale can occur on any type of material.

These problems reduce the flow of water and can lead to contamination. In serious cases, they can cause pipe breaks.

To assess the level of corrosion, we carry out water quality tests and visual inspections.

Fouling is usually detected by measuring the water pressure at different points in the system.

Importance of Regular Inspection and Robotic Video Inspection

Regular inspections are essential to prevent serious problems.

We recommend annual checks for residential systems and six-monthly checks for commercial buildings.

Robotic video inspection is a non-destructive technique that allows us to examine the inside of pipes.

This technology is particularly useful for pipes that are difficult to access.

With a high-resolution camera, we can identify cracks, obstructions and other hidden problems.

This information is vital for planning effective repairs and extending the life of the pipes.

Rehabilitation and Maintenance

The refurbishment and maintenance of old pipelines is essential to ensure the proper functioning of hydraulic systems.

These practices extend the life of the installations and prevent serious problems.

Non-Destructive Methods for Pipe Rehabilitation

Non-destructive methods are an excellent option for rehabilitating pipes without causing major disruption.

A popular technique is CIPP (Cured-In-Place Pipe), which creates a new pipe inside the old one.

Pipe bursting is another effective method. It replaces the old pipe with a new one made of high-density polyethylene.

For one-off repairs, internal epoxy coating is a quick and efficient solution.

These techniques avoid extensive excavations, reducing costs and environmental impacts.

Substitution of Materials and Use of Modern Technologies

Replacing old materials with more modern options improves pipe performance.

PVC and PPR are popular choices for hot and cold water.

For sewage systems, high-density polyethylene offers durability and resistance. Copper pipes are still a reliable option for some applications.

New inspection technologies, such as robotic cameras, help to identify problems with precision.

This allows for more efficient and targeted repairs.

Regular Maintenance Planning and Failure Prevention

A regular maintenance plan is crucial to avoid failures and reduce costs in the long term.

Regular inspections can detect problems such as blockages or clogs before they become serious.

Regular cleaning of pipes prevents buildup and extends their service life.

It is also important to check the water pressure and possible leaks.

For irrigation systems, we have specialized teams in Lisbon to carry out these services efficiently.

Frequently Asked Questions

Old piping raises a lot of questions for homeowners. These common questions help clarify the main points about maintenance and repair.

What is the estimated cost of replacing old pipes?

The cost varies according to the size of the property and the material chosen.

In Lisbon, a complete replacement can cost between 3000€ and 10000€ for a typical apartment.

Factors such as access to the pipes and additional repairs influence the final price. It is advisable to ask for several quotes from qualified professionals.

What are the signs that I need to repair my sewer pipes?

Persistent bad smells are a clear sign. Other indicators include:

  • Frequent blockages
  • Strange noises in the pipes
  • Moisture stains on walls or ceilings
  • Mold growth

When you notice these signs, it's crucial to act quickly to prevent further damage.

How is pipe rehabilitation carried out without complete replacement?

There are modern methods that avoid extensive construction work.

One of them is the internal coating, where a special resin is applied inside the existing pipes.

This technique creates a new smooth and resistant surface. It is ideal for pipes that are difficult to access, saving time and hassle.

Is there any solution for exposed pipes without putting them inside the walls?

Yes, there are aesthetic and practical options.

A popular solution is to use decorative ducts to hide the pipes. These can be painted to match the decor.

Another alternative is to install custom-made furniture that integrates and conceals the pipes.

These solutions are quick and do not require structural work.

What are the best techniques for repairing a water leak in a PVC pipe?

For small leaks, special adhesive tapes or epoxy resins can be temporarily effective.

In more serious cases, replacement of the damaged section is necessary.

It is important to turn off the water before any repairs. To ensure a lasting job, we recommend calling in a professional.

How can I deal with the issue of rust in old pipes?

Rust is a common problem with old metal pipes. A professional cleaning can help temporarily.

However, replacement is often the best long-term solution.

Copper or PVC pipes are modern alternatives that resist corrosion better. An experienced plumber can assess the situation and recommend the best approach.
