How to Fix Hard to Turn Symmons Shower Valve?- 5 Steps Solution

Buildups are the main reason for a stuck shower valve. Most of the time, mineral deposit from water blocks the screws inside the valve. Sometimes dirt and corrosion damage the screw mechanism. That’s when the valve gets stiff and you find it hard to move.

We’ve prepared a 5-steps guide to help you overcome the shower valve issue. Dive deep into the instructions thoroughly to fix the stuck valve.

Mandatory Tools

Before we get into the fixing procedure, you should go on a search for today’s required tools. Here’s what you need to proceed-

  • Philips head screwdriver
  • Flathead screwdriver
  • Pliers
  • Adjustable wrench
  • Lubricant
  • Vinegar

Now that we’ve gathered all the tools, let’s go through the steps. Make sure to follow every step to successfully fix the valve.

Step 1 of 5: Close the Water Supply

Turn off the main water supply valve. Then turn down the Symmons shower valve. You should do an observation to see if there’s any water leaking from the shower.

Gently try to turn off the hot and cold shower valves. If they are in a frozen state, don’t put too much pressure on them. This can snap off the valve and increase your work.

Step 2 of 5: Remove the Valve

Take off the plastic caps and uncover the screws. Use a Phillips head screw to remove the screws around the valve.

If the screws holding the valve are small, the Phillips head screw won’t work. Use Allen wrenches to remove the tiny screws.

Once all the screws have been removed, the retaining nut will be loosened. Now remove the retaining nut and pull out the valve. You’ll be able to see the valve stem.

Step 3 of 5: Clean the Valve

Clean the valve stem and valve thoroughly. Use a scrub and soap water to clean everything initially. Then, look for rust and mineral buildup. If you notice any oxidization, use vinegar to remove the rust

Notice the cartridge carefully. If it’s damaged, broken, or rusty, you should change it. It is best to replace a new shower cartridge.

We have a list of industrial-grade cartridges for you. So you don’t have to look elsewhere. Go through the list and choose the suitable one for you-

Product 1
Product 2

These cartridges don’t get rusted easily. They are strong and last longer. 

After cleaning everything, take a towel to dry the parts.

Step 4 of 5: Reassemble the Faucet and Lubricate the Valve

After replacing the cartridge, you have to attach the faucet back. Properly assemble the shower faucet and reattach it. 

Attach the retaining nut to the faucet. Put the screws back around the shower valve. Now take a lubricating agent of your choice and lubricate the shower valve. You can use Silicone grease as it works best on shower valves. You can use normal grease also. 

Don’t worry about the grease contaminating your shower water. This grease never reaches your water line. The grease helps to loosen the valve a little bit. Also makes it easier for you to turn the handle.

Step 5 of 5: Check the Shower Valve

Let the main water supply open. Check if you can glide the shower valve smoothly now. If you can turn the valve smoothly, it’ll work properly. Check for water leaks around the shower valve area.

You can still be unable to control the water flow after fixing the valve. This incident doesn’t occur for the shower valve. Your water pipes might have a pressure regulator issue that needs fixing. 

We’ve successfully finished fixing the tight shower valve. Now with all the instructions, we hope that the process will be more organized and easier for you. 

You can find it hard to turn the valve even after fixing it. It might have other water line-related problems. Reaching out to a professional plumber would definitely bring you a goodnight sleep.
