It is possible to increase the water flow through your tub spout by placing a mixture of remover over the spout. Calcium and lime deposits can build up inside your tub spout as you use the bath and shower over time. This will cause the flow of water to slow and make it seem that it is barely coming out of the tub spout.
In order to reduce the impact of the lime and calcium build up you will need to place a bucket of calcium deposit remover over the tub spout to immerse it or remove the tub spout to help improve the water flow. This article describes the steps, materials and tools necessary to improve the water flow in your tub spout.
Step 1: Fill Bucket with Calcium Deposit Remover
Fill a bucket with calcium deposit remover solution, such as Lime-X. You will need to place enough solution into the bucket in order to submerse the tub spout when the bucket is placed over it. Hold the bucket up in order to submerse the tub spout and get the solution inside of it. This should start an immediate chemical reaction in order to remove some of the lime and calcium build up inside the tub spout.
You may want to get a small stool or step ladder that is of sufficient height in order to keep the bucket in place for several hours while you allow the calcium deposit remover to work on removing the buildup.
Step 2: Remove the Tub Spout
If is not possible to hold or position the bucket in place, you will need to remove the tub spout in order to soak it in the bucket filled with calcium deposit remover. Take an adjustable wrench and place it at the back of the tub spout. Turn the tub spout counter clockwise to loosen it in order to remove it from the wall. Use a putty knife to scrape any silicone caulk that remains on the tile.
Step 3: Place the Tub Spout into the Bucket
Take the tub spout once it has been removed from the bath and place it in the bucket filled with the calcium deposit remover. Allow the tub spout to sit in the bucket for several hours in order to completely remove as much of the calcium or lime build up that is inside.
Step 4: Put the Tub Spout Back
Using a caulk gun, place a bead of silicone caulk on the tile where the tub spout will be reattached. The silicone caulk is needed to provide a seal between the wall and the tub spout and prevent any leaking or water accumulated inside the wall that may cause damage. Put the tub spout back on in the opposite manner you removed it from the bath tub. Run the water once the tub spout has been secured to test the cleaning and you should notice an improvement in the water flow.
