Removing rusted overflow drain screws can be a challenging task, but with the right tools and techniques, it can be done effectively. Here are the steps to remove rusted overflow drain screws:
1. Gather the necessary tools: adjustable wrench, penetrating oil, screwdriver or drill with screwdriver bit, and pliers.
2. Apply penetrating oil to the rusted screws and let it sit for a few minutes to loosen the rust.
3. Use an adjustable wrench to grip the screw head firmly and try to turn it counterclockwise. If it doesn’t budge, tap the end of the wrench gently with a hammer to provide extra force.
4. If the screw still won’t turn, use a screwdriver or drill with a screwdriver bit to remove the screw.
5. If the screw head is completely stripped, use pliers to grip the screw and turn it counterclockwise.
6. Once the screws are removed, clean the area and replace the screws with new ones if necessary.
Remember to use caution when working with rusted screws to avoid damaging the surrounding area.
Overflow drains are essential components in bathtubs and sinks. They serve the purpose of redirecting excess water back into the drainpipes to prevent flooding when certain levels are reached. However, there may be instances when the overflow drain screws become rusty, resulting in rust deposits in the sink or tub. Fortunately, replacing them is a relatively simple process.
Preparing for Overflow Drain Repairs
Bathtub overflow drains are usually located beneath the faucet and may have covers secured with screws. Standard sink overflows, on the other hand, can be found underneath or on the backside of sink basins. These overflows do not require screws and direct the extra water into the drainpipes of your home.
If the screws on the bathtub overflow drain are rusted, they need to be removed and replaced. The first step is to examine the screw heads and select the appropriate screwdriver, preferably one with a long handle to facilitate access. The tools you will need for removing rusty overflow drain screws depend on the method you choose to tackle the project.
Loosening the Screws
For this repair method, you will also require a rag, penetrating lubricant, and a rubber band. Start by using the rag to clean off any mildew or mold that may have accumulated on the surface of the drain, and ensure it is thoroughly dry. Apply the lubricant to the screws and allow it to sit for approximately five to ten minutes.
Insert the screwdriver into the first screw. Apply pressure with one hand while using the other hand to rotate the screwdriver counterclockwise. If the screw head begins to strip (indicating that the slots have deteriorated and the screw cannot be turned), place a rubber band or narrow piece of rubber between the screwdriver and screw head after it has been loosened. If this does not help further loosen the screws, you will need to try an alternative method.
Other Techniques for Removing Screws
One option is to insert a hacksaw blade into the drain opening and press it against the screws located at the back of the drain cap. Saw slowly and carefully to avoid scratching the tub.
Alternatively, you can use a chisel to chip away some wood around the screw head. Once this is done, you may be able to grip the screw head with a pair of locking pliers and turn the screw.
Using a drill may be more effective than a screwdriver as it provides more force. Remember to wear safety glasses to protect your eyes and use the appropriate drill bit and screw extractor, which are typically included in a drill set. Attach the bit to the drill and drill into the center of the rusted screw. Then, insert the extractor screws into the hole and drill counterclockwise for a brief moment.
Preventing Rust on Drain Screws
Rust is a chemical reaction that occurs when iron comes into contact with oxygen and moisture over time. To prevent your drain screws from rusting, you can take measures to protect them from moisture. This can be achieved by using sealants and protective coatings such as Rust-Oleum.
For replacing the corroded screws, you have the option to purchase rust-resistant screws; stainless steel screws are believed to have better resistance to rust compared to other metals. It is also advisable to regularly inspect and seal the screws of the overflow drain. Additionally, it is important to regularly clean them.
