Are you tired of the annoying pulsing sound coming from your shower pump? Do you find it frustrating when the water pressure in your shower fluctuates, making it difficult to enjoy a relaxing bath? You’re not alone. Many homeowners experience this issue, but few understand the underlying causes. In this article, we’ll delve into the world of shower pumps and explore the reasons behind the pulsing phenomenon.
What is a Shower Pump?
Before we dive into the causes of pulsing, let’s first understand what a shower pump is and how it works. A shower pump is a device that increases the water pressure in your shower, providing a more enjoyable and invigorating bathing experience. It’s typically installed in homes with low water pressure, such as those with gravity-fed systems or homes located at the end of a long water supply line.
A shower pump works by using an electric motor to drive a centrifugal pump, which increases the water pressure by accelerating the water flow. The pump is usually connected to the cold water supply line and is designed to provide a consistent flow rate and pressure.
Causes of Pulsing in Shower Pumps
Now that we understand how a shower pump works, let’s explore the common causes of pulsing:
1. Air in the System
Air in the system is one of the most common causes of pulsing in shower pumps. When air enters the pump, it can cause the pump to vibrate, leading to a pulsing sound. There are several ways air can enter the system, including:
- Air leaks in the pipes: If there are any air leaks in the pipes, air can enter the system and cause the pump to pulse.
- Incorrect installation: If the pump is not installed correctly, air can become trapped in the system, leading to pulsing.
- Blockages in the pipes: Blockages in the pipes can cause air to become trapped, leading to pulsing.
2. Incorrect Pump Sizing
If the pump is not sized correctly for your shower system, it can cause pulsing. A pump that is too small may not be able to provide enough pressure, leading to a pulsing sound. On the other hand, a pump that is too large may provide too much pressure, causing the pump to vibrate and pulse.
3. Worn or Faulty Pump Components
Worn or faulty pump components can also cause pulsing. Over time, the pump’s components can wear out, leading to a decrease in performance and an increase in pulsing. Common worn or faulty components include:
- Worn bearings: Worn bearings can cause the pump to vibrate, leading to pulsing.
- Loose or corroded connections: Loose or corroded connections can cause the pump to malfunction, leading to pulsing.
- Failed seals: Failed seals can allow air to enter the system, leading to pulsing.
4. Pipe Resonance
Pipe resonance is another common cause of pulsing in shower pumps. When the pump is operating, it can cause the pipes to vibrate, leading to a pulsing sound. This is especially common in systems with long pipes or pipes with a small diameter.
5. Pressure Fluctuations
Pressure fluctuations in the water supply line can also cause pulsing in shower pumps. When the pressure in the supply line fluctuates, it can cause the pump to vibrate, leading to pulsing.
How to Fix a Pulsing Shower Pump
Now that we’ve explored the common causes of pulsing in shower pumps, let’s discuss how to fix the issue. Here are some steps you can take:
1. Check for Air Leaks
The first step is to check for air leaks in the pipes. Inspect the pipes and connections for any signs of air leaks, and repair or replace them as needed.

What is a shower pump and how does it work?
A shower pump is a device that is installed in a plumbing system to increase the water pressure in a shower. It works by using an electric motor to drive a pump that pushes water through the pipes, increasing the pressure and flow rate of the water. This is especially useful in homes where the water pressure is low, or where there are multiple showers or faucets being used at the same time.
The pump is usually connected to the cold water supply line and is activated when the shower is turned on. It then pumps water through the hot water supply line, creating a balanced pressure between the hot and cold water. This results in a stronger and more consistent flow of water from the showerhead, making for a more enjoyable and refreshing showering experience.
What causes a shower pump to pulse?
A shower pump can pulse due to a variety of reasons, including airlocks in the system, blockages in the pipes, or a faulty pump. Airlocks occur when air enters the pipes and gets trapped, causing the pump to work harder and resulting in a pulsating or vibrating noise. Blockages in the pipes can also cause the pump to work harder, leading to a pulsating effect.
Another common cause of a pulsating shower pump is a faulty or worn-out pump. Over time, the pump’s motor or impeller can wear out, causing the pump to vibrate or pulse. In some cases, the pump may also pulse due to a faulty pressure sensor or a malfunctioning control unit. It’s essential to identify and address the underlying cause of the pulsing to ensure the pump operates efficiently and effectively.
