Plumbing Problems & Tubs Holding Water

Identifying the Problem

• Investigate possible plumbing problems if you notice your tub is not holding water correctly; the problem may be easier to fix than you might think. Make sure the water is not running down the shower curtain to the corner of the tub and spilling out. You can easily resolve this problem buy purchasing a small dam that sticks in the corner of the tub to prevent water from spilling out. Check to see if water is leaking constantly or only when the tub is full of water. Water may be leaking only when the faucet is running. These factors will help you diagnose the problem accurately.

Water Line Leak

• If the leak is constant, even when the tub is not running or filled with water, chances are you have a leak in the hot or cold water line. Repairing these “hidden” leaks requires the expertise of a licensed plumber or bathtub repair contractor unless you have experience performing such repairs. Water line leaks do not resolve themselves, so act quickly to avoid costly damage to the surrounding floor board and ceiling below if the tub is on the second floor.

Tub Leak

• If the tub is not holding water properly but only leaks when full, you may have a leak in the tub itself. Check the sealant at the bottom and sides of the tub for cracks or disintegration. Empty the tub, remove the old damaged sealant and apply new, heavy-duty sealant. Allow it to dry overnight before using the bathtub again. You may also have a leak in the body of the tub. Observe the tub closely for cracks and check to see if water is dripping out the side. Cracks may be very tiny and hard to see, but you should be able to find them. Apply epoxy sealant to cracks and allow it to dry.

Faulty Drain Plug

• Another common problem that can cause a tub to lose water is a faulty drain plug. If you have a basic rubber drain plug, make sure it is the right size for the drain. Look for damage to the plug such as pinholes or disintegrated edges. Replacement rubber drain plugs are available at most hardware stores. If you have a mechanical drain plug, make sure it is working properly. Water should not escape when the bathtub is full.
