The most common causes of a dripping tap are wear and tear on the washer, O-rings, or cartridge seals. This can easily be fixed through the replacement of the internal valve parts. This article shows you the thorough steps on how to fix a leaky tub faucet​ using standard plumbing procedures. ## **What are the Common Causes of Leaks in Tub Faucets?** ### Damaged Faucet Stem: - The inner mechanism controlling the flow of water. ### Worn Washer: - A rubber seal that may become hardened or broken with time. ### Faulty Cartridge: - Commonly seen in new single-handled faucets. ### Damaged Faucet Spout: - Malfunctions in the diverter or the spout itself. ## **What are the Various Types of Faucets?** There are various types of faucets. Being aware of what you have in your building will enable you to know the correct parts to purchase for the repair. ### Compression Faucets: - These are the most common faucet types in older buildings, where a washer “compresses” to prevent water from flowing. ### Cartridge Faucets: - These types of faucets are commonly found in newer buildings, with plastic or brass cartridges regulating water flow and temperature. ### Ball Faucets: - These are commonly found in kitchens and operate through a ball bearing mechanism. ## **What Tools Will I Need to Repair a Leaky Faucet?** - Phillips and regular head screwdrivers - Adjustable wrench or socket wrench - Washer or cartridge replacement part (specific for your model) - Teflon plumbing tape - Silicone sealant - Heat-resistant plumber’s grease ## **How to Fix a Leaky Tub Faucet​ in Just Seven Steps?** ### 1. Turn Off the Water Supply and Drain the Lines Find the valve that controls the water supply to your bathroom. It can usually be found either in the basement, crawl space, or outside the house. After shutting off the valve, open the faucet in your bathtub to drain the pipes of any water left inside. This will relieve the pressure and ensure that the water is clean before starting the dismantling process. ### 2. Disassemble the Faucet Handle Disassemble the handle from the faucet by using the screwdriver. Remove the cap covering the handle and the screw located on the handle. You can use the adjustable wrench in case the handle doesn’t come out easily. ### 3. Inspect the Internal Parts Once the handle is removed, examine the washer, valve stem, and cartridge to see if there are any worn-out or corroded areas. Removing these components will take around 15 minutes. ### 4. Change the Washer or the Cartridge When you have dismantled the faucet, identify the kind of internal fittings your tap has: #### Compression Faucet (Washer): - Change the old rubber washer with a new one. In case the faucet still leaks after this, then the cartridge might be leaking. #### Cartridge Faucet: - Using your pliers, remove the cartridge from the valve assembly (you may need to remove a brass clip for some models). Pay attention to the way in which the cartridge is mounted on the valve body. The cartridge replacement should be carried out according to the same scheme for hot and cold water to mix correctly. | _Tip: Take your used items along when buying new ones. This guarantees that your spare cartridge or washer matches your old one perfectly._ | | --- | ### 5. Lubricate and Reassemble A small amount of heat-resistant plumber’s grease should be placed on the new washers or O-rings of the new cartridge. The purpose of doing so is to ensure that there is no friction in the handle. At the same time, this helps avoid the drying up of the parts. Then, carefully put them back into place in the valve body. ### 6. Check the Faucet Spout Should there still be a problem, then it’s clear that your problem is with the spout. The removal of it, however, can be quite complicated. 1. Firstly, the spout must be removed by loosening it with the aid of a wrench or a socket wrench. 2. Next, the sealant should be cleaned off to release the pipe from its fix to the wall. 3. Then, the length of the pipe must be removed using a wrench and wrapped with plumber’s tape at both ends of the length of pipe. 4. Lastly, the new spout will be put back into the elbow pipe on the wall with sealant applied again. ### 7. Verify Your Work Gradually open the water valve. Allow the water to run from the tap for about a minute. This should help remove any air or particles from the line. 产品介绍卡片 – 50/50 布局 ![](https://www.aimfaucet.com/wp-content/uploads/2025/10/ound-2-hole-wall-mounted-Bathroom-Faucet-DG510-1.webp) **Round 2-hole wall mounted Bathroom Faucet DG510** AIM DG510 round concealed wall faucet: H59 brass, ceramic cartridge, single lever.

The reason for the failure was attributed to the tear in the neoprene washer. Water high in mineral content had caused erosion in the rubber. The solution entailed replacing the washer, creating a proper seal, and fixing a daily leakage of five gallons. ### Case Study #2 Another case study involved ceramic disc cartridges used in high-volume conditions. They proved to be more durable than the previous valves. However, the problem was caused by dirt entering the valve. Flushing the lines before installation extended the lifespan by 40%. Moreover, proper maintenance and debris filtration are vital for long-term performance. ## **Conclusion** Understanding these steps on how to fix a leaky tub faucet help prevent structural damage caused by persistent moisture. Plumbing fixtures must also meet standards like ASME A112.18.1/CSA B125.1 to handle pressure spikes without failure. Moreover, ISO 9001 ensures consistent manufacturing quality and cUPC confirms safety compliance. AIM is known for manufacturing large volumes of professional-quality plumbing systems. Precision engineering is ensured by employing the latest methods of gravity casting and CNC milling. Meanwhile, extensive testing, including leak tests up to 500,000 cycles, ensures durability and trustworthiness. With that, our products ensure compliance with global standards.
