Water Coming Out of Shower Head When Filling Bathtub: Easy Fixing

Sometimes, water may keep coming out of the showerhead when filling the bathtub. This water can cause damages to the bathroom floor. For instance, it enhances the growth of molds on the floor if the floor is left wet for a long time. Water coming out of the showerhead when filling can be caused by several reasons, such as distortion of shower head parts.

Once you identify the issue, try to fix it instantly to avoid increases in water bills and floor damages such as the growth of molds due to increased moisture on the floor surface. If water keeps coming out of the showerhead when filling, inspect your shower carefully and determine the cause.

Causes of water coming out of the showerhead when filling the bathtub

There are many reasons which can cause your water to keep coming out of the showerhead when filling the tub. They include;

  • The shower diverter valve keeps redirecting water from the water tank to the showerhead and forcing the water to drip out of the shower.
  • Shower parts are wearing out.
  • Shower parts become attached loosely to hold water in position.
  • Pumping too much water into the shower increases the pressure forcing water to come out of the showerhead.

If you discover your shower head is dripping water, try fixing the problem instantly by following the manufacturer’s instructions.

Steps on how to troubleshoot water coming out of the showerhead when filling the bathtub

Once you experience any problems concerning water dripping from the showerhead, follow the recommended steps to fix the problem successfully.

Step 1: collect all equipment required to fix the problem

Materials you will need include; screwdriver, new parts to replace the worn-out shower parts, a wire brush, and vinegar to wash the shower after fixing the problem.

Step 2: Disconnect the water supply from the valve that supplies water to the bathtub and the whole room

After gathering all materials required, disconnect the water supply from the valves to the whole house while concentrating on the bathtub. Disconnecting the valve prevents the flooding of more water on the floor. While disconnecting the valves, ensure you are careful to avoid damaging water supply valves. In addition to that, examine your water supply valve carefully for any damages and attempt to fix the issues identified.

Step 3: Unscrew the showerhead and disconnect it from the wall

Remove the showerhead from the wall using a screwdriver and a wrench to unscrew the bolts holding the showerhead in position. The wrench holds the screwdriver and the bolts in position for easy screwing in the required direction. Ensure you unscrew the bolts gently to avoid cutting them or damaging the showerhead. Moreover, ensure you unscrew in an anticlockwise direction to avoid damaging the bolts.

If the bolts have undergone any rust and the screwdriver fails to remove them, try using other methods such as a mini-hacksaw, bolt cutter, reciprocating hacksaw, and drilling machine to cut the bolts. While cutting the bolts, ensure you are careful to prevent damaging the showerhead.

Step 4: Inspect the showerhead carefully

Check the showerhead to identify any faults. Check the showerhead parts if they are worn out. Finally, check the showerhead parts if they are loosely attached.

Step 5: Remove all dirt from the showerhead using recommended water and detergent

Once you have correctly inspected the showerhead, remove all dirt accumulated on or on the surface of the showerhead. Otherwise, ensure you clean the showerhead carefully to avoid damaging other parts of the showerhead. Hold the showerhead carefully to avoid losing small internal showerhead parts.

Step 6: Get rid of the old showerhead parts

After identifying any damaged or worn-out materials, dispose of all the materials recommended by the manufacturer and buy new ones for replacement. Install each new material into the required positions to ensure your showerhead functions as required if the parts are replaceable.

Moreover, ensure you buy replacement materials that suit your showerhead. When reinstalling the new parts, ensure you are careful to avoid damaging the whole showerhead.

Step 7: Mount the showerhead on the wall and screw it firmly

After installing the new showerhead parts, slowly mount your showerhead back onto the wall. Scre

w the showerhead firmly on the wall using a screwdriver. Screwing the showerhead firmly on the wall prevents it from falling off while using the showerhead. Also, ensure the bolts are placed in the correct holes and tightened as required.

Step 8: Connect the water valve supplying water to the bathtub and the whole house

Switch on the valve that you disconnected at first to allow water to flow to the bathtub. Leave the water to flow for some time into the showerhead.

Step 9: Test your showerhead if it is working perfectly

After successfully reinstalling all materials in their correct location, test your showerhead to see if water still comes out of the showerhead when filling the bathtub. If the problem persists, repeat all the processes above to fix your showerhead.

If all the methods fail to fix the problem, consider replacing the showerhead because the problem might be the whole showerhead. The showerhead can be damaged at times, causing water to drip out of the showerhead when filling the bathtub. Therefore, carry out the full inspection on the showerhead and determine if the showerhead is in good condition.
