You are taking a shower and then you notice that water is barely coming out from the shower head. If ever you experience something like this, I am telling you, there is something wrong with your shower diverter. You may ask, "What should I do? I barely know anything about plumbing!" Well, here is good news. When you notice that something isn't normal in your shower, checking it immediately will be a wise move to do and as a matter of fact, you can fix it yourself!

Setting the problem aside may just aggravate the condition of the diverter. The problem that should have been simple may complicate and even get you to spend so much. Chances are, your shower diverter stuck.

Why stress when you can have a working shower diverter ?

Shower diverter is a valve which controls water flow to a particular outlet. For example, when your bathtub faucet is combined with your shower, a shower converter is attached. When you intend to use the shower, you can have water coming out because it blocks the tub faucet.

Why do we have to deal with stuck problem?

There are several reasons why shower diverter stuck occurs. Obviously, when you are not getting enough water flowing from your shower head, there could really be a problem. It doesn’t take a genius to realize this. A simple test would be, opening the bathtub faucet to check if there is a normal flow of water.

Replacement may come into your mind right away. However, it would be preferable to conduct an inspection to determine if it really needs replacement. Although buying a shower diverter isn’t that expensive and replacement will only take you half an hour the most.

There are two main reasons why shower diverter gets stuck.

#1 Buildup

As discussed earlier, the function of the shower diverter is to block water from flowing to the main faucet when you wish to use your shower. So basically what it does is to change its position whenever you use the shower. Any build up in its vicinity will hinder its movement. That is why you will also notice that there will be some water coming out from the main faucet.

What to do:

  • Your diverter could be the switch type or the pull up-push in type. Regardless of the type, what you can do is to gently tap the converter handle. Giving that “just about enough” jostle could loosen the buildup.
  • Remember that your tap should be gentle because if you overdo it, you might aggravate the problem you are facing. If nothing happens even with a few gentle tap, then the problem may be more than just a simple buildup.

#2 Corrosion

The metal reacts with water and over time the reaction will manifest. This reaction is called corrosion. This usually happens in the bathtub spout. When it does, it affects the functioning of the shower diverter. Another area where corrosion happens is in the screw threads where it connects the pipe into the spout. The corrosion causes buildup. Ignoring it will result for water to seep into the wall.

What to do:

  • For “pull-up faucet,” what you can do is to twist the faucet upside down. Clean the faucet before getting the faucet back to its position. You will need pliers and gentleness to do this!Pull up faucet
  • For “push-in faucet,” locate the screw which can be found under the spout. Unscrew so that you can twist the faucet up. Use pliers to loosen the rubber washer. Once it is loose, you can easily check for any buildup. Be sure to clean thoroughly before putting the faucet back to its original position.Push in faucet

Practical and guaranteed solutions on how to fix your shower diverter dilemma

If you are the kind of person who doesn’t mind getting your hands dirty, then you can replace your shower faucet diverter with these easy to follow steps.

  • You can find a screw at the center of the diverter handle. Open this using the flat-head screwdriver. All you need to do is to turn the screw counterclockwise. Once the screw is fully detached, take the diverter handle off.
  • In case, you have difficulty in taking it off because it seems to be stuck, get hold of the entire thing and pull it with controlled force. Twist the handle gradually until it is completely pulled off. If and when it still doesn't work, you can secure a faucet handle puller. This is not difficult to find in any hardware store.

3. Check for the hollow tube and escutcheon

Inspect the handle that you have just taken out. In the handle you will find two things at the back:

  • Hollow tube
  • Escutcheon

You will need to remove these two items by simply spinning them. If the escutcheon is screwed, you will need to take it off.
