Bathtub Won't Turn Off: Essential Troubleshooting Tips

A bathtub that refuses to turn off can be a frustrating and potentially costly problem. However, with some basic troubleshooting, you may be able to resolve the issue yourself without having to call a plumber.

Here are the critical aspects to consider when your bathtub won't turn off:

1. Check the Faucet Handles

The first step is to inspect the faucet handles. Ensure they are tightly closed and not loose. If the handles are loose, tighten them using a wrench or pliers. If the handles are still not closing properly, they may need to be replaced.

2. Inspect the Cartridge

The cartridge is a component within the faucet that controls the flow of water. If the cartridge is faulty, it can cause the faucet to leak or remain on. To inspect the cartridge, remove the faucet handles and check for any visible damage or debris. If the cartridge is damaged, it needs to be replaced.

3. Examine the Diverter Valve

The diverter valve directs water flow between the bathtub spout and showerhead. If the diverter valve is malfunctioning, it may fail to shut off the water supply to the bathtub. To access the diverter valve, remove the bathtub spout or showerhead. Inspect the valve for any blockages or damage. If necessary, clean or replace the diverter valve.

4. Check the Water Pressure

Excessive water pressure can strain the faucet and cause it to leak or remain open. To check the water pressure, connect a pressure gauge to the bathtub faucet. If the pressure is above 80 psi, you may need to install a pressure-reducing valve to regulate the water flow.

5. Inspect the Pop-Up Drain Assembly

The pop-up drain assembly is a mechanism that seals the bathtub drain when not in use. If the drain assembly is faulty, it can prevent the bathtub from draining properly. Inspect the drain assembly for any blockages or damage. If necessary, clean or replace the drain assembly.

Conclusion

If you have tried the troubleshooting steps outlined above and your bathtub still won't turn off, it is advisable to contact a qualified plumber for professional assistance. They can assess the situation and perform any necessary repairs or replacements to restore the proper functioning of your bathtub.
