Our plumbing service covers cold and hot water pipework, drainage, taps, water heaters and boilers, and urgent repairs. Climate control (air conditioning, aerothermal) is handled as a separate service, coordinated when the works require it.
In homes older than 30 years, old galvanised iron or corroded copper pipework is common, with flow problems, noise and leaks at old joints. A full renewal replaces that material with modern multilayer pipework, with lower noise and better corrosion resistance.
Plumbing also includes domestic hot water production (electric heaters, gas boilers) and drainage within the property. Air conditioning and aerothermal heat-pump systems for climate control, by their own nature (refrigerant circuit, fluorinated gases), are treated as a separate service — see Climate control.
A complete plumbing intervention includes pipework replacement from the meter to every tap, drainage (drains and internal wastewater pipes in the home) and domestic hot water production. Air-based climate control has its own page.
Plumbing is designed following the water pathway: from the main connection to the last tap, passing through DHW production and drainage. Each stretch answers to a different logic.
Main meter, main shut-off valve and inlet filter: the first reading of the system. Good routing starts here.
Vertical cold- and hot-water columns, with shut-off valves per room so works can be done without cutting off the whole home.
Taps and fittings connected to branches of the correct section, with flow limiters and aerators.
Drains with minimum slope to the siphon trap, sound-insulated wastewater pipes and inspection chamber before the shared stack.
Boiler or heater connected to the hot-water circuit and, in larger homes, a return loop for immediate availability at distant taps.
The supply network works under pressure; the drainage network works by gravity. Understanding the difference is key to designing bathroom or kitchen plumbing without surprises.
Operates under pressure from the meter. Carries cold and hot water to every consumption point with sections sized by simultaneous flow. Allows horizontal and vertical routing with few restrictions.
Works by gravity towards the shared stack. Requires a continuous minimum slope, siphon traps to prevent odours, and is very hard to change once closed. Dictates where sink, basin, shower and WC can go.
Domestic plumbing concentrates in three rooms with distinct technical demands. Renovating any of them means revisiting the involved supplies and drains.
Sink, dishwasher and, in some cases, washing machine. Single-lever or pull-out tap, under-counter or over-island.
Shower or bath, basin, WC and bidet where present. Thermostatic shower taps and accessible shut-off valves.
Basin, WC and, where space allows, a compact shower tray. Fewer supplies but the same technical demands.
Taps for washing machine/dryer, specific siphon trap and, in villas, auxiliary sink with drain.
Boiler, water heater or heat pump on a dedicated circuit, with safety valves and expansion vessel as required.
Pressurised supply and gravity drainage run on separate paths with their own materials, slopes and tests. Pressure testing seals the trace before any wall is closed.
Before tiling or closing a false ceiling with plumbing inside, we check four essential technical points to prevent future leaks.
Hydraulic test for at least two hours above service pressure before closing chases.
Verification of minimum slope in every drain from the siphon trap to the stack.
Shut-off valves per room installed in accessible access panels, not under continuous tiling.
Elastic fixings on stacks and sound-insulated pipework in embedded sections crossing bedroom areas.
The pressure test closes the hidden phase. From that point on the taps, shower columns and radiators decide the daily experience of the installation.
Plumbing has some important technical and legal conditions.
The vertical riser is usually shared with the building; replacing it affects the neighbours. Interior pipework of the home is changed without community agreements.
Costa del Sol water has medium-to-high hardness that accelerates wear on heating elements, taps and heaters. Fitting water softeners extends equipment life.
Gas installations require project and licensed-installer certificate, with mandatory periodic review. It is not equivalent to general plumbing.
Replacing the main pipework requires cutting off water for hours. It is coordinated in advance to minimise disruption at home.
Residential plumbing in Málaga combines cold and hot water pipework, drainage and domestic hot water production. Homes older than 30 years often still carry galvanised iron or aged copper pipework with flow, noise and leak issues at the joints: complete replacement with modern PEX-AL-PEX multilayer is the most frequent intervention in our complete renovations and in full bathroom reworks.
Air-based climate control (air conditioning, aerothermal) has its own service because it requires fluorinated-gas handling and specific professional authorisation. At reformasmalaga.net we keep plumbing (water, drainage and DHW) separate from climate control so the client can contract exactly what they need. DHW production is resolved with an electric heater, a condensing gas boiler or a heat pump depending on the consumption profile and the available installations.
When there is visible corrosion at joints, reduced flow, frequent noise or repeated leaks. If the installation is also pre-1990s, complete replacement usually works out better than successive spot repairs.
They share some installations (water network, condensate drains) but are different services: air-based climate control requires handling fluorinated gases and specific professional authorisation. We provide both, but as separate services with their own pages and independent quotes.
You will receive an initial cost estimate within 24 hours and a free on-site technical visit to assess your case.
