Why Shower Knob Turns without Producing Water

Your shower knob may turn, but you receive no water. Yes, encountering such a problem can be challenging, ruining your bathroom experience. The common victim of this issue is usually a faulty valve. And sometimes, it may need replacement or servicing. Alternatively, the issue could have been coming from a faulty handle.

With a stripped handle or worn-out valve stem, I would recommend replacing the entire unit. However, I don’t see the need for you to panic because a procedure to diagnose this issue is simple and even buying the spare part isn’t expensive unless you own a special faucet that lacks spare parts in most hardware.

We shall teach you how you can fix a shower knob that turns but you get no water. Besides, you will also understand some tricks that can help have water by fixing the valve. Sometimes you may don’t have to substitute anything at all while solving this problem.

Troubleshooting a shower knob that turns with no watershower knob turns but no water

There’s a simple approach to determine a hard knob. Disconnect its handle and then scrutinize the notches located on a valve stem. Try to inspect the internal part of the handle before scrutinizing the notches into the slot. If you are a good observer, you should be able to point out various ridges.

1. Simple trick

You have to understand that it’s not straightforward to change the valve stem of the shower only; you’ll be forced to replace a complete valve.

2. Using a screwdriver to correct the issue momentarilyUsing a screwdriver to correct the issue momentarily

It’s possible to tackle the issue using a hex-wrench and a screwdriver, though this will offer a temporary solution. You should therefore begin by removing the cap sealing the handle’s set screw with the help of a flathead screwdriver.

On the cap, you will see the manufacturer’s logo or the circle painted red and blue. Unfortunately, on showers with lever-style handles, the cap might be located beneath the lever, meaning that you’ve to search for it.

Try tightening the set-screw. Here, you only require a screwdriver, ensuring the screws grasp the handle tightly. You can use a hex wrench to handle side-mount screws. Sometimes these screws may be loose and reversed; if this is the case, I am sure your issue is solved.

Detach the screw and apply some thread-locking components to avoid the problem recurring; tighten the screw down. If you have tightened the screw and fail to solve the issue, try wrapping the valve using three complete revolutions of available plumbing tape.

You should make sure that the holder is tight but avoid overdoing it; retaining the lever back might be problematic. Change the handle before tightening the set screw; your shower may know it works again. But note that this easy fix is only a temporary one, but it may serve you for a certain period while planning to swap the grip or entire valve stem.

3. Swapping the valve stemSwapping the valve stem

If you operate with a shower with a striped stem, substituting the full valve could be the finest resolution. Terminate the water supply to your shower before unbolting the valve and get it out. If the Moen shower’s lever is stripped, you must stretch out the spongy clip using a pair of pliers.  Eliminate the valve now.

If you realize that your valve is sticky with scale, consider it worn out and call for a substitute. You may have to seek the help of a crock-screw-like tool that is designed to remove stuck valves. After eliminating the valve, carry it with you to the nearest hardware shop for consultation on how to get the correct replacement. Alternatively, you can acquire useful information from an online spare parts plumbing shop.

4. Restoring or changing the handleRestoring or changing the handle

Which way to go? Since shower faucets are made from plastic materials, sometimes they may crack. Maybe you should first try sealing the crack using two-part epoxy glue. It can solve the issue based on the location of the crack.

Another trick is that your job will be sturdier when using a C-clamp wrench to grasp the fractured part together. Do so immediately after smearing the glue. If you’re unable to fix the shower handle, maybe it’s the right time to substitute it.

Carry the handle with you to the nearest hardware shop to buy a suitable replacement. Sometimes if you aren’t in a hurry, place some orders directly from your manufacturer. Alternatively, you may order the same from a trusted online plumbing spare part shop.

 FAQs:

  • Why am I not receiving water from my shower?

Sometimes this problem may be caused by a minor clog on the showerhead. It’s a defect with a showerhead component to the shut-off arm or valves to the water supply. Sometimes this issue might happen due to a chronic fault with pipes in your home.

  • Why is my shower knob turning continuously?

When turning the knob, the splines will communicate with the stem, reducing or increasing water flow via the faucet. But, when the knob rotates uselessly, splines may be stripped or affected with corrosion.

  • How can I reset my shower?

You may power on an electric supply to your shower and then wait for about 30 seconds. Next, tap on both the flow and the start buttons simultaneously. Start by beeping, releasing the start button, and then do the same on the flow button. Your shower should be on; leave it on until it turns itself off.
