A bathtub leak can quickly lead to inconvenience, such as water damage or increased consumption. Fortunately, there are effective solutions for repairing these leaks, even without advanced expertise. Discover the steps and methods for solving this problem quickly and permanently.
Identify the source of the leak
Before starting, it’s essential to pinpoint the source of the leak. The most common leaks are :
- Joints: Joints around bathtubs can deteriorate over time, allowing water to seep in.
- At the siphon or drain pipe: A loose connection or damaged pipe can cause leaks.
- On the surface of the bathtub: A crack or impact can lead to leakage.
Cut off water supply
Before starting any work, turn off the water supply if necessary and make sure the bathtub is completely dry. This will facilitate diagnosis and repair.
Repairing leaks around joints
Clean the area: Remove old joints with a cutter or spatula. Clean the surface with a degreaser to remove soap and limescale residues.
Apply a new seal: Use a waterproof sanitary silicone and apply it following the tub’s perimeter. Smooth the joint with a damp finger or suitable tool to ensure a perfect seal. Allow to dry according to the manufacturer’s instructions before using the bath again.
Repairing a drain leak
Check connections: Make sure that all siphon and drain connections are tight. If any gaskets are worn, replace them with suitable new ones.
Apply sealing paste: If connections are not completely watertight, use sealing paste or tape to reinforce them.
Repairing a crack in the bathtub
Clean and prepare the surface: Degrease and dry the cracked area to ensure good adhesion of the repair materials.
Use epoxy resin: Mix the resin according to the manufacturer’s instructions and apply it directly to the crack. Smooth the surface with a spatula and allow to harden. Once dry, sand lightly to obtain an even finish.
Apply a specific repair kit: For acrylic or enamelled cast-iron bathtubs, suitable repair kits are available. They contain materials that blend perfectly with the original material.
Test the repair
Once the repairs have been made, turn the water back on and test the bathtub by filling the bottom with a small amount of water. Watch carefully for any persistent leaks.
Prevent future leaks
Maintain your seals regularly: Clean them and replace them as soon as they show signs of deterioration.
Avoid abrasive products: These can damage the bathtub surface and seals.
Watch fittings: Periodically check the tightness of siphons and pipes to prevent leaks.
