How to Prevent Airlocks in Shower Pump Systems
The showering pump system should be efficient to provide good pressure and give comfortable showering. However, airlocks in the pump or the pipes hinder water flow and can be very inconvenient causing a lot of performance issues. As for the problems with water pressure, Dublin Shower Pumps supplies professional solutions to these problems. In this Blog let me explain what the causes of Airlock are, what it does, and how we can avoid it.
Understanding Airlocks in Shower Pump Systems
Airlocks are usually caused by air being locked either in the water pipes or in the air pump so that water cannot pass through regularly. As shower pumps are designed for water supply, even a tiny leakage of air can interrupt the work of the pump.
What Causes Airlocks in Shower Pump?
- Incorrect Installation: If it is poorly positioned to the shower pump or pipes then it has areas where air can build up.
- Low Water Levels: If the water tank supplying the pump runs low, air can be drawn into the system.
- Sudden Water Supply Interruptions: Sudden changes in water supply, for instance during repairs, the air enters into the pipes and the pump system.
- Improper Priming: If, after the installation or maintenance, the proper priming has not been carried out, then air will be locked inside.
How airlocks affect your shower pump.
- Reduced Water Pressure: Airlocks prevent water from flowing evenly or with low pressure – an issue that shower pump installation was supposed to solve.
- Pump Damage: If operations continue with airlocks, it will heat the pump and cause mechanical wear.
- Noisy Operation: The air present in the system causes sounds like rattling or gurgling when the pump is on.
- Increased Energy Use: An airlocked pump needs to work harder to provide adequate water pressure and therefore requires more energy.
How Do I Know If My Shower Pump Has an Airlock?
You can easily spot an airlock in your shower pump by watching for these signs:
🚿 Low or uneven water pressure – water flow weakens, pulses, or stops unexpectedly.
🔊 Unusual noises – humming, gurgling, or rattling sounds from the pump or pipes.
⚡ Pump runs without water flow – the unit activates even when no taps are on.
💧 Intermittent spluttering – air spits out of the showerhead before steady water flow.
🧰 Frequent cycling – the pump turns on and off repeatedly for short bursts.
If these issues appear, air is likely trapped inside your system. Our Dublin Shower Pumps team can bleed the lines and restore proper pressure safely.
Simple Steps to Avoid Airlocks in Shower Pumps
To avoid potential problems with your shower pump, you need to take measures. Here are expert tips from Dublin Shower Pumps:
1. Ensure Proper Installation
The most important aspect of using a shower pump is installation.
- Correct Positioning: Make sure that the pump is installed at the correct level from the source of water. For positive head pumps, the position of the water tank should be above the pump level. Negative head pumps, on the other hand, prove most suitable where the water tank is at a level with, or below, the pump.
- Angle the Pipes Appropriately: It is recommended to put the pipes at a slight angle that will make it hard for air spaces to develop. Avoid sharp or horizontal curves so that the air can’t be trapped in them.
2. Regular System Maintenance
Regular checks help to identify any complications likely to occur, allowing for proactive action to be done on them before there is a major outbreak.
- Inspect the Pump and Pipes: Check for any damage or leaks where the air can penetrate the shower pump system.
- Clean the Filters: Clogged filters reduce the water pressure and may increase the chances of airlocks in the system. Regularly clean or replace the filters.
- Check Water Levels: Sufficient water supply in the tank must be maintained to avoid the air entering into the pipes.
3. Use Automatic Air Vents
Automatic air vents are one of the dependable methods of eliminating air from the system.
- Install Air Vent Valves: These are valves that allow the trapped air to escape as water moves through the pipe system. Place them at high areas in the piping where you expect air to accumulate.
- Consider Pressure Relief Valves: Besides air vents, it is also important to use pressure relief valves to regulate the system and minimize air-related problems.
4. Prime the Pump Correctly
Pump priming makes certain that there is no standing air inside the pump after its assembly or when in the process of repair.
- Fill the Pump with Water: Before starting the pump, manually fill it with water to expel any air.
- Follow Manufacturer Guidelines: Always follow the important instructions provided with the manufacturer guidelines to prevent the risk of airlock in the pumps.
5. Upgrade to a High-Quality Pump
The upgraded high-quality pumps will prevent the airlocks.
- Choose Trusted Brands: Dublin Shower Pumps provides clients with an efficient shower with different pumps, and quiet and energy-saving showers that solve water pressure-related issues.
- Consider Pump Features: Look for features that have built-in air extraction mechanisms that eliminate trapped air.
Troubleshooting Airlocks in Your Shower Pump System
Nevertheless, sometimes, airlocks can develop. Here’s how to deal with them effectively:
- Turn Off the Power: To avoid any damage or even injury do not operate the pump while attempting to make repairs.
- Manually Release Air: Open the nearest taps to let out air. In case of severe airlocks, slightly loosen the pipe connections to let the air out then secure the connection tightly.
- Flush the System: Turn on the water at a high flow rate to help push the air out of the system. This is particularly useful in minor airlocks.
- Call a Professional: If the problem continues, Dublin Shower Pumps can assist in identifying and solving the problem to give your system the necessary fix.

Frequently Asked Questions – Preventing Airlocks in Shower Pumps
Airlocks usually happen when air gets trapped in the pipes — often after a water tank refill, maintenance, or low water levels. That trapped air blocks water flow and makes the pump run noisily or stop working properly.
The key is proper installation and regular checks. Keep the water tank topped up, bleed trapped air from time to time, and install automatic air vents in high spots. These small steps can save you a lot of frustration later.
You can try turning off the pump, opening the nearest taps, and running the water until the air escapes. If the noise or pressure issue doesn’t go away, it’s best to get a professional to inspect it safely.
That’s a classic sign of trapped air or a small leak causing the pressure sensor to trigger. It’s worth checking for dripping taps or loose fittings. If you’re unsure, our Dublin Shower Pumps team can diagnose it quickly.
If you’ve tried bleeding the system and it still hums or won’t build pressure, yes. A certified installer can safely remove the trapped air and prevent damage to the pump motor.
