Pipe Replacement in Barcelona | Comprehensive Network Renewal

The water comes out brown or yellowish when turning on the tap: It is an unmistakable symptom of internal rust and corrosion in steel or old copper pipes. This phenomenon is very common in the **Sants-Montjuïc** estates built in the 60s.

Metallic or earthy taste in drinking water: Indicates that the material is degrading and shedding particles (copper or lead) that contaminate the water. The WHO establishes very strict limits for these heavy metals.

Frequent leaks in different parts of the home: If every year you repair a different leak (in the kitchen, then in the bathroom, then in the hallway), the network is exhausted and fixing it is like putting a band-aid on a hemorrhage.

The risks of not changing them: In addition to silent lead poisoning, a general blowout of a hot water pipe can cause a catastrophic flood affecting several lower floors, with repair costs that can easily exceed €10,000. The community of neighbors could claim these damages if you do not keep the indoor installation in good condition.

We exclusively install **fifth-generation multilayer pipes**, composed of an internal layer of PE-RT (high temperature resistant polyethylene), an intermediate layer of welded aluminum (which acts as an oxygen barrier and prevents thermal expansion) and an external layer of PE-RT. This sandwich endows the pipe with extreme flexibility, pressure resistance (20 bars) and a useful life exceeding 50 years.

In addition, we include **elastomeric foam insulating casing** 13 mm thick on all DHW (Domestic Hot Water) pipes. This prevents the dreaded heat loss on the way and, most importantly in Barcelona, prevents **condensation** that often rots kitchen cabinets and generates mold on false ceilings.

It's the million-dollar question. Copper has been king for decades, but it has a drawback: it is expensive and, over time, it corrodes due to the acidity of the water (especially in the metropolitan area of Barcelona, where the water has a slightly acidic pH). Multilayer pipe is 30% cheaper in material, is easier to install (requires no fire soldering) and, thanks to its aluminum layer, it does not expand or contract with temperature changes, which eliminates the 'creak-crack' noises that are so annoying on winter nights. At Plumber Express we recommend multilayer for new builds and comprehensive rehabilitations due to its value for money and ease of maintenance.

We recently carried out a complete change of pipes in a 120 m² apartment on **Carrer Muntaner, corner with Diputació**. The building, from 1955, had lead pipes in 70% of the installation. The owner, a family with young children, was concerned about lead levels. We acted for 3 days. We canceled the old network, installed distribution manifolds in the bathroom and kitchen, and insulated all the hot water pipes. The result: crystal clear water, improved pressure and a monthly bill that dropped €15 because there were no more micro-leaks. The family invested €3,200 and gained peace of mind and health.

Specialists in old buildings: We know in detail the structural problems of the Eixample (brick vaults) and Gràcia (air chambers) apartments. We know where to pass the pipes without damaging the structure.

Clean and organized process: We leave the passage areas free of rubble at the end of each day. We use industrial vacuum cleaners to eliminate the dust from the chases.

5-year guarantee: Our commitment to quality is absolute. If a joint fails in the first 5 years, we repair the installation at no cost to the customer.
