The bathtub is one of the most reliable plumbing fixtures in your home, but it is not immune to occasional issues. Fortunately, many of those issues are easily repaired. Here are some of the most common problems you could face and what you can possibly do to fix it.
Jets Not Working
If you have a jetted bathtub and it is not functioning properly, the problem could rest with the power supply. If the pumps will not start, ensure that the power to the tub is on. If the tub is not connected, you will need to connect it. Turn off the power before reconnecting it.
If the jets continue to not work, the issue could be related to the voltage level. Check your manufacturer's manual to determine what the voltage level should be for the pump. If the pump is incorrect, it needs to be replaced. However, if it is correct and the pump is still not working, contact a professional.
No Hot Water Pressure
In the event that your bathtub does not have any hot water pressure, the problem could be related to the faucet. Mineral deposits can build up in the faucet and cause the water pressure to decrease.
To return the water pressure to its normal strength, remove the faucet and clean its aerator. You can soak it in white vinegar to remove the deposits. You also should consider flushing your hot water heater if you have noticed decreased pressure throughout the home. To flush the water heater, turn off the water supply valve to it and drain the water in the tank. Once the water is completely drained, turn on the water to the heater again, but allow it to run for up to a minute.
A fiberglass bathtub can develop cracks sometimes. The cracks are usually a sign that the bathtub is not well supported. Even if it has a concrete base for support, it is possible that additional support is needed.
To add support, you can install expandable polyurethane foam beneath the bathtub. The foam needs time to dry after the installation. Once dry, the foam should support the tub adequately when weight is applied to the tub. If the cracking continues, contact a professional.
Consult with a professional plumber before attempting any significant bathtub repairs. A plumber can assess the damage and help decide the best way to resolve the issue.
