Why is my bathtub faucet leaking?

Natural wear of the seals

The rubber seals on your bathtub faucet gradually deteriorate due to temperature fluctuations and constant water pressure. This natural wear particularly affects the faucet head and internal components , creating microscopic gaps through which water escapes.

To limit risks during repairs, our OBLOC absorbent bags can be temporarily placed under the tap. The average lifespan of a seal is 5 to 7 years, but intensive use or very hard water can accelerate its deterioration. A worn seal can be recognized by its cracked texture and loss of elasticity.

Limescale buildup

Limescale gradually builds up in your bathtub faucet , creating a layer that clogs the faucet components . This clogging increases the pressure inside the faucet and forces the seals, causing leaks with costly consequences.

To prevent this considerable damage , regular cleaning with white vinegar helps remove deposits. During this descaling operation, our OBLOC® absorbent bags protect your bathroom from potential splashes. If limescale has already caused damage, rapid intervention with multi-grip pliers and replacement of defective parts is required.

The defective cartridge of the mixer tap

A bathtub faucet that becomes difficult to operate often indicates a faulty cartridge . This central component regulates the flow and temperature of the water. Over time, its components wear out and create micro-leaks that quickly worsen.

To prevent any risk of flooding during the diagnosis, place an OBLOC absorbent device around the mixer tap. Preventive replacement of the cartridge every 8 to 10 years helps prevent future leaks . If you notice abnormal resistance from the handle or an unstable temperature variation, do not wait to act.

The different types of leaks to identify

The continuously dripping faucet

Four liters of water wasted per hour: that's the reality of a constantly dripping faucet . This constant leak often stems from limescale buildup or worn internal seals. To protect your bathroom during the inspection, our OBLOC absorbent bags provide an effective barrier.

A leak under a kitchen sink , just like a bathtub faucet, can cause significant damage if not addressed in time.

Inspecting the faucet section requires an adjustable wrench and a flathead screwdriver to remove the faucet handles . Before performing any work, turn off the water supply to avoid the risk of damage and mold . A mixer tap may require different maintenance than a conventional mixer tap.

Faced with the economic consequences of a persistent leak, it's best to act quickly. If initial repair attempts fail, don't hesitate to call a plumber or visit a hardware store to find the right type of replacement parts. When a leak persists, water can accumulate until it reaches sensitive areas, such as a flooded basement .

The leaking thermostatic mixer

Among the faucet systems , the thermostatic mixer is a complex unit requiring special attention. Its failure can release up to 20 liters of water per hour. To secure the area during the diagnosis, place an OBLOC absorbent bag under the equipment.

The main causes of malfunctions are a worn thermostatic cartridge or improper installation . Regular descaling and replacement of seals every 5 years prevent future leaks . For optimal protection during work, our flood protection strips create an effective barrier around the work area.

The leak under the base of the faucet

A dark spot or trickle of water leaking from the faucet -to -bath joint indicates a failed base seal. This critical area is under significant pressure with every use. For accurate diagnosis, our OBLOC flood sock liners create a safe work area around the faucet.

A worn silicone seal or improper tightening of the mounting nut are usually the cause of this leak. A simple test is to run your finger over the base: a feeling of moisture confirms the problem. A socket wrench can be used to tighten the nut, but replacing the seal completely remains the best guarantee of a leak.

Emergency solutions to stop the leak

Turn off the main water supply

The first step in dealing with a leak is to locate the main shutoff valve . Located near the water meter or in your garage, it is closed by turning it clockwise. To absorb any residual water during this operation, place our OBLOC absorbent bags around the area.

Check the effectiveness of the seal by opening a downstream tap. If a few drops persist, our flood protection rods create a protective barrier while we identify the exact source of the leak. A simple test is to wipe the area and observe if the moisture reappears.

Use our OBLOC® flood bags

Quickly position OBLOC absorbent bags around the leak area to contain the water flow. These devices expand up to 24 times upon contact with water, forming reliable protection in minutes.

Stacking the bags provides a protective height of 30 cm. For maximum effectiveness, arrange them in a staggered pattern and ensure they are in good contact with the ground. Lightly spray them with water to accelerate their activation and adhesion.

Install protective tubes

OBLOC anti-flooding strips adapt perfectly to the contours of your bathtub. Their elongated shape creates a waterproof barrier along the joints and around the faulty faucet. Place them in direct contact with the surface to be protected for optimal absorption.

Once in place, the draught excluders provide reliable protection against water leaks. Their absorbent material traps water and prevents it from spreading to sensitive areas of your bathroom. For greater stability, lightly moisten the base of the draught excluder before installation.

This temporary solution gives you time to calmly organize the repair of your faucet. The valves remain active for several hours and can be repositioned as the situation evolves.

How to fix a leaky bathtub faucet?

Replacing worn seals

Start by examining the texture of the gasket: a rough surface or micro-cracks indicate a need for replacement. Use an adjustable wrench and a flat-blade screwdriver to gently remove the faucet handle.

The success of the replacement depends on the accuracy of the disassembly. Remove the old O-ring without scratching the metal surface and carefully clean the housing. The new seal must match the original dimensions exactly to ensure a perfect seal.

Check for other secondary seals around the faucet stem and body. A complete replacement prevents future leaks and extends the life of your faucet.

Grohe mixer repair

When faced with a leaking Grohe faucet , methodical repair is essential. Before handling your faucet, place an OBLOC® absorbent pad under the work area to prevent damage. Unscrew the faucet handle with an Allen key and remove the chrome cover.

Use a socket wrench to remove the clamping nut and remove the ceramic cartridge . Limescale often forms deposits that complicate this step. Carefully clean the cartridge location with white vinegar.

A new Grohe cartridge guarantees an optimal seal. When reassembling, check the alignment of the positioning pins for smooth operation of your mixer.

Changing the cartridge

A faulty faucet cartridge will cause uncontrollable temperature and flow fluctuations. To replace it, first turn off the water supply and protect the work area. Then remove the faucet handle to access the clamping nut.

The new cartridge must be an exact match to the original model. Note the reference number on the old one or take a photo of it before going to a specialist store . A thorough cleaning of the cartridge housing with white vinegar will remove any limescale residue before installation.

When reassembling, ensure the alignment of the marks and the direction of insertion are correct. A gradual water pressure test can be performed to check for leaks before normal use.

Tools needed for repair

The special bathroom adjustable wrench

Choose an adjustable wrench with protected jaws to preserve the chrome finish of your faucets. Its compact size makes it easy to access tight spaces behind your bathtub.

For maximum efficiency, choose a model with an adjustable opening of up to 30 millimeters. This range allows you to work on all types of standard faucet nuts. A non-slip coating on the handles ensures a secure grip, even in wet environments.

Store your wrench in a dry place after use and regularly check the adjustment mechanism to maintain its accuracy. Light lubrication of the moving parts will extend its lifespan.

A replacement gasket kit

A complete gasket kit contains various models suitable for common faucet brands. Flat gaskets are used for fittings, while O -rings ensure the seal of moving stems.

Store your new gaskets in a dry place at a constant temperature. Temperature fluctuations can deform the rubber and compromise their effectiveness. A standard kit includes models ranging from 8 to 24 millimeters in diameter.

Before installation, briefly soak the new gasket in warm water to improve its flexibility. This technique makes it easier to install and strengthens its adhesion to the faucet housing.

Anti-limescale products

To effectively treat limescale in your faucets, use a special anti-limescale spray for sanitary ware. Before handling, place an OBLOC® absorbent bag under the area to protect your floor from product splashes.

White vinegar remains a formidable natural alternative against deposits. Mix it in equal parts with water in a spray bottle. Apply the solution to the scaled areas and let it sit for 30 minutes.

A professional anti-limescale gel penetrates hard-to-reach areas. Its long-lasting action gradually dissolves deposits without damaging chrome surfaces. Remember to rinse thoroughly after each application to neutralize residue.

Prevent future leaks

Regular maintenance of the mixer tap

The lifespan of your bathtub faucet depends directly on the care you give it. Monthly cleaning with a soft cloth and soapy water is enough to prevent residue buildup.

Remember to place an OBLOC absorbent bag under the work area before each maintenance operation. This precaution prevents splashes on your floor while cleaning the aerator or lubricating moving parts.

Check the joints for smooth movement and the handle every three months. Lightly greasing the moving components with a food-grade lubricant ensures smooth movement and maintains the seal.

Water pressure control

A faucet that spits violently or lacks flow often indicates a water pressure problem . Equip yourself with a pressure gauge to measure the pressure accurately: it should be between 2 and 3 bars for optimal operation.

When adjusting pressure, place an OBLOC® absorbent bag under the work area. This precaution protects you from water splashes when handling the pressure reducer or shut-off valve.

Gradually adjust the pressure by turning the adjustment screw in quarter turns. A quick flow test at each tap will confirm that your system is properly balanced.

OBLOC® protection solutions

When faced with flood risks, our OBLOC® bags and sock liners embody French innovation in protection. Their unique organic polymer composition allows for absorption of up to 24 times their initial volume in just 3 minutes.

Lightweight and compact, these devices fit easily in a closet or car trunk. Once activated by water, they create a waterproof barrier that effectively protects your home from water damage.

Our range adapts to every need: from stackable bags for large areas to flexible bags for hard-to-reach areas. Each product is reusable and remains active for several hours after activation.

When to call a professional?

The push button is stuck

Is your push button no longer switching between the shower and bath positions? This common situation is often the result of limescale buildup in the mechanism. Before handling, place an OBLOC® absorbent bag under the work area to prevent splashes.

Start by spraying diluted white vinegar around the button. Let it sit for 30 minutes to soften the deposits. Then gently move the button in both directions without forcing it. If the blockage persists, disassemble the mechanism using a suitable socket wrench .

Lightly greasing the moving parts with a food-grade lubricant will restore the smoothness of the mechanism. Test the operation several times to confirm complete release before normal use.

Old leaky faucets

Faucets over 10 years old are at increased risk of leaks due to the general wear and tear of their components. An old faucet can leak up to 20 liters of water per day, creating an emergency situation for your home.

To secure the area while a professional is working, place an OBLOC® absorbent bag under the faucet. Its immediate absorption capacity protects your bathroom from unexpected spills. A second bag placed along the wall provides additional protection.

Installing a new faucet requires careful preparation. Start by photographing the existing connections and accurately measuring the center distance between the water inlets to choose a model compatible with your configuration.

Mixer tap problems

Remove the faucet neck with a suitable wrench as soon as the first drops appear. This part of the faucet, located between the body and the spout, is subject to significant mechanical stresses that weaken the internal seals.

Carefully clean the seal housing with a soft brush to remove any limescale residue. An OBLOC® absorbent bag placed under the mixer tap during the cleaning instantly captures any accidental spills.

Apply a thin layer of silicone grease to the new seals before reassembly. This lubrication ensures optimal sealing and extends the life of the components.
