Repair of the plumbing switch of the shower valve

When you invest in a quality shower valve, you expect nothing but the best performance. However, this isn’t always the case, as unexpected problems arise. 

If there is one reliable valve brand that has withstood the test of time, it’s the Hudson Reed shower valve. The valves are designed for aesthetics and performance. What’s more exciting is that you can use them alone or with other products. 

However, several customers and reviewers have pointed out certain problems present in Hudson Reed valves. Common among them was that water remained lukewarm and not warm enough. Luckily, there are proven solutions to problems arising from using the valves. 

Here, we focus on the problems with Hudson reed valves and how to solve them. 

Water Is Lukewarm

There is no better way to end or start your day than having a hot shower. For most people, this is the expectation when investing in a Hudson reed shower valve. However, this isn’t always the case, as reported by some reviewers. 

According to one reviewer on Amazon, they invested in a Hudson reed shower only for it to disintegrate just 1-2 years after purchase. The result was the hot and cold water mixing without control. 

Even though the problem could result from, among other things, incorrect heater temperature and a malfunctioning dip tube, the main cause, in this case, is a damaged shower valve. According to experts, a damaged shower valve causes an imbalance in cold and hot water. 

Luckily, you can easily fix this problem to enjoy your shower again. If you lack the relevant skills, we recommend seeking help from a plumber. 


  • Hack saw
  • Drop cloth
  • Needle-nose pliers
  • Screwdriver set
  • Angle grinder
  • Standard pliers
  • A Hudson reed valve
  • Caulk


  1. Put the drop cloth below the shower. This helps to block off your shower drain, thus preventing washers and screws from getting down the drain. Additionally, it maintains the cleanliness of the area. 
  2. Turn off the water supply to your home and remove the shower handle to access the shower valve. Unscrew the trim plate and then clean them well. 
  3. At this point, you can remove the retainer clip. The new valve comes with a brand-new retainer clip. You can then remove the shower valve cartridge using standard pliers. Ensure you understand the faucet’s inside appearance to make everything easier during reinstallation. The best idea would be to take a video while removing everything.
  4. Refer to the video you took above to install the new valve cartridge. Normally, the cartridge slides without problems. Secure the cartridge with a retainer clip. 
  5. Finally, turn on the water supply and check whether it is hot enough. If it works properly, reattach the shower handle and trim plate. However, if the problem persists, it’s time to involve a plumber. 

Lack of Water or Low-Pressure Flow

Some Hudson reed valve owners have raised issues with the showers experiencing low pressure or, in the worst cases, no water at all. Although this can be associated with a lack of water or a clogged water system, it also results from clogged valves. Worry not if you’re experiencing this problem, as it can be corrected. 

Follow the steps below:

  1. First, shut off your water supply and open the valve. Remove the trim piece and handle from the valve. 
  2. Unthread and remove the cartridge from the valve and soak it in vinegar for one hour. As the cartridge soaks, turn on the shower to flush its opening. For this purpose, use the cold water side. 
  3. Finally, replace the valve and tighten the temperature stop. Remember to also reattach the handle and trim. 

Whistling Sound

Many customers have also reported their Hudson reed shower system producing funny sounds. In most cases, the system is experiencing some pressure. Such pressure could result from blockage or clogging in the valves, thanks to mineral buildup. 

We have discussed the solution to a clogged valve system above (under lack of water or low-pressure flow), and you can follow the same steps to solve this whistling problem. 

At times, the whistling could be emanating from the showerhead. Here, you need to replace the whole showerhead. We recommend seeking assistance from a plumber. 

Leaking Valve

A leaking valve is a common problem in Hudson reed valves and other reputable brands. When the valves leak, they result in low water pressure and increased wastage of water. Consequently, you might be forced to pay higher water bills. 

For most people, replacing a leaking valve is a difficult task. However, with the right knowledge, you’ll need less than one hour to correct the issue. The most important thing is to purchase an original Hudson reed valve. Additionally, you need to have an Allen wrench and screwdriver. 

Below are the steps:

  1. First, turn off your main water valve. Doing this will offer you a clean working environment.
  2. Proceed to unscrew the handle. Here, use an Allen wrench to make everything easy. 
  3. It’s time to unscrew the trim plate and get it off the shower wall. You can also remove various screws in the cartridge collar. 
  4. Replace the collar with one from Hudson reed. Ensure you tighten the collar screws. You can remove the trim plate and replace them with new ones. Proceed to tighten the plate with screws. 

If the valve continues to leak, perhaps you can involve a professional plumber. However, be prepared to pay them a service fee. 


How well you enjoy your shower depends on the shower valve’s effectiveness. However, there are times when the valves misbehave, causing unexpected inconveniences. For instance, the Hudson reed valve sometimes experiences leakages, emits whistling sounds, and produces lukewarm water. 

You can follow the above guidelines to correct the problem and enjoy your shower. We recommend involving a plumber for better results.
