Tap Replacement Services in Belgium
A tap that drips non-stop, a stiff mixer handle encrusted with limescale, or water seeping unnoticed into the vanity cabinet: faulty faucets cause continuous water wastage and structural damage to countertops. A clean, professional replacement of your kitchen mixer, bathroom basin tap, or shower valve restores effortless operation, reliable water pressure, and dependable leak-free seals.
In Belgium, particularly in Brussels, Flanders, and Wallonia, tap water is rich in calcium and magnesium. Over time, mineral build-up destroys ceramic cartridges and degrades rubber washers. Whether you need us to install a designer faucet you purchased yourself or supply a durable, professional-grade mixer, our licensed plumbers complete the swap swiftly and cleanly. Send a photo of your tap and connections along with your municipality for an initial assessment.
What to specify in your first message
- Your Belgian commune/city and property type (apartment, house).
- The fixture location: kitchen sink, bathroom vanity, cloakroom basin, bath, or shower.
- Type of mixer desired: single-lever mono, pull-out spray, thermostatic bar, or pillar mixer.
- Whether functional shut-off angle valves (Schell valves) exist under the basin.
- Whether you already have the new tap or wish us to provide a certified unit.
- Clear photos of the tap from above and the supply pipework underneath the unit.
Why replace a worn or leaking tap promptly?
Water wastage & rising utility bills
A tap dripping at a rate of 4 litres per hour wastes up to 35,000 litres of water annually, unnecessarily inflating your Belgian water bill.
Hard water & seized cartridges
Belgian tap water limescale clogs internal ceramic discs. Forcing a stuck lever often fractures the tap neck or distorts copper feed pipes.
Concealed cabinet damage
Deteriorated flexible hoses or faulty base seals leak silently inside under-sink cupboards, warping wooden chipboard and causing black mould.
Modern comfort & scald protection
Upgrading to a thermostatic shower mixer ensures constant temperature regulation and an integrated 38°C safety stop for peace of mind.
Comprehensive faucet & mixer solutions
Our experienced plumbers handle all domestic tap replacement requirements in Belgium:
- Kitchen sink mixers: High-spout swan-neck models, 360° swivel spouts, pull-out vegetable sprays, and folding mixers designed for in-front-of-window installations.
- Bathroom basin & vanity taps: Smooth single-lever ceramic disc mixers equipped with eco aerators and mechanical pop-up waste linkages.
- Bath & shower thermostatic mixers: Wall-mounted bar mixers with standard 150 mm pipe centres, diverter valves, and overhead shower connections.
- Isolation valves & utility bib taps: Replacement of calcified under-sink angle valves (Schell), toilet cistern fill valves, and frost-resistant garden taps.
Proper connections, flexible hoses & Belgaqua standards
Installing a tap involves more than simply tightening a retaining nut. Misaligned pipework or over-twisted flexible hoses introduce vibration and hydraulic water hammer.
We systematically fit brand-new stainless-steel braided flexible hoses matching Belgian plumbing standards (Belgaqua approved), complete with fresh synthetic rubber washers and verified 3/8″ or 1/2″ connection threads. If the existing isolation valves under the sink are seized from age, we replace them during the same call-out to guarantee long-term safety.
Safe checks you can do before scheduling
Before our technician arrives, you can carry out these simple diagnostic steps:
- Inspect under the basin for small chrome angle stopcocks. Try turning them gently clockwise by hand.
- If valves are absent or seized, locate the main building water shut-off tap near the water meter.
- Dab a dry tissue around the tap base and underneath the flexible connections to verify where water escapes.
- Never apply heavy pliers to a severely rusted valve stem, as weakened copper can tear under sudden force.
- Photograph both the fixture above the counter and the pipework beneath the sink.
When to call a professional plumber immediately
- Water drips continuously along the flexible hose into the floor structure or cabinet base.
- The under-sink mounting horseshoe nut is heavily rusted and inaccessible without specialized tap spanners.
- The faucet body wobbles loosely and water penetrates under the worktop cut-out.
- The operating handle sheared off completely upon turning.
- The thermostatic shower mixer only outputs scalding hot or icy cold water due to cartridge failure.
How a professional tap replacement works
The call-out starts by closing local isolation valves or the main water supply and relieving internal system pressure. The old mixer and worn supply tails are disassembled carefully, avoiding scratches on ceramic glaze or damage to countertop laminate.
The mounting surface is thoroughly descaled and degreased. The new tap is seated with its base O-ring gasket and secured firmly with reinforced mounting hardware. New braided stainless-steel hoses are connected without tension. The water supply is then restored under full operating pressure to test flow rates, hot/cold mixing, and absolute watertightness.
Tap replacement costs: key pricing factors
The exact price to replace a tap depends on realistic job factors: accessibility beneath the sink (deep vanity drawers, tight service cavities), the degree of corrosion on original retaining bolts, the requirement to swap defective isolation stopcocks, and whether the customer provides the fixture or requests a commercial-grade unit with warranty.
We avoid deceptive flat-rate gimmicks that inflate upon arrival. For a clear, upfront estimate, send your municipality and two clear photos of your tap setup.
Tenants, landlords & Belgian tenancy laws
Under Belgian tenancy regulations, routine maintenance such as descaling aerators and replacing worn rubber washers is typically the tenant’s responsibility. However, replacing an obsolete, cracked, or irremediably broken faucet due to age and normal wear is the landlord’s obligation.
If you are renting, request your landlord’s consent prior to replacing fixtures. We provide comprehensive itemized invoices detailing parts and labor suitable for property management reimbursement.

Frequently asked questions — Tap replacement
Can I supply my own tap and hire you solely for installation?
Yes, certainly. You are welcome to purchase your preferred tap from a DIY store, bathroom showroom, or online retailer. Our plumber will inspect its dimensions and install it professionally with new seals and verified connections.
How long does a standard tap replacement take?
For a standard kitchen or basin tap with working isolation valves, installation takes between 45 minutes and 1.5 hours. If mounting bolts are heavily rusted or angle valves need replacement, expect approximately 1.5 to 2 hours.
Why is water leaking under my kitchen sink when I run the tap?
This commonly occurs when the O-ring seal between the tap body and sink fails, letting splash water penetrate underneath, or when the braided flexible hose develops a micro-perforation under water pressure.
Do you need to shut off the water for the entire building?
Not if your sink is fitted with functioning Schell angle isolation valves. We simply turn off the local valves. If isolation valves are seized or absent, a brief shut-off at your private water meter is needed.
What is a Schell valve and why is it important?
A Schell valve is a compact chrome quarter-turn or screw angle stopcock connecting wall supply pipes to tap flexes. It allows instant local isolation for maintenance or in case of a burst hose without depriving the entire household of running water.
How can I prevent limescale from damaging my new tap in Belgium?
In high-hardness areas (Brussels, Brabant, Liège), unscrew the aerator nozzle every two months and soak it in white vinegar. For comprehensive protection of appliances and pipework, installing a domestic water softener is highly recommended.
