Step 4: Checking The Stem End Of The Faucet

The goal is to identify any obvious damage. Preferably, the stem tip has ridges that have the purpose of attaching the stem to the faucet handle. 

These ridges tend to wear out over time, which leads to the faucet handle coming loose around the stem. Because of this reason, the bathtub faucet won’t turn off. Therefore, you will have to change the part where ridges are not defined anymore. 

Step 5: Examine the Inside Of The Faucet Handle

Check carefully to discern any visible damage. A cracked handle will need to be replaced since it will not give a firm grip on the stem. If the grooves within the handle have smoothen out, the faucet won’t turn off.

Use a miniature brush to clean off any debris that might have accumulated in the stem end. Once done, use a rag or cloth to dry the stem. 

Step 7: Wrap The Stem Tip

Cover the valve of the stem with thread seal tape ; only a couple of layers will be sufficient. 

Then, push in the faucet handle over the thread seal taped stem. A different way to do this is rotating the faucet handle over the stem till it firmly secures into place. 

Step 8: Checking Your Faucet

Unlock the valve and turn the tap on and off several times to see if the water keeps leaking out or not. If there is no dripping, bear in mind that the thread seal tape will only work for a short period of time. It’s just a temporary solution for whenever the faucet won’t turn off. 

Eventually, you will have to buy a new faucet.
