Stuart Turner Pumps Problems

Stuart Turner pumps are widely used in households for the supply of hot and cold water. However, like all mechanical devices, these pumps can sometimes face issues that disrupt their normal functioning. This article addresses a specific issue related to the operation of these pumps and provides potential solutions.

Problem: The main issue described involves a delay in the pump’s activation when a tap is turned on. Specifically, the pump takes around 3 seconds to start after the tap is opened. Once activated, the pump doesn’t operate continuously; instead, it cycles on and off. This intermittent operation is not only inefficient but also quite frustrating for the user. The problem persists even after servicing the pump and replacing the sensors.

Potential Solutions:

1. Check the Age and Model of the Pump: Understanding the age and exact model of your pump can be crucial in diagnosing issues. For Stuart Turner pumps, a long number located on top of the pump provides this information.
2. Bucket Test: By disconnecting the load side pipes and allowing the pump to run water into a bucket, users can ascertain if the problem is with the pump or the system. If the pump runs perfectly during this test, the problem may be related to the system’s pressure or other components.
3. Examine the Pump Type and Pressure Vessel: For those using a negative head or universal pump, it’s important to check the pressure in the vessel. A malfunctioning pressure vessel can be a significant cause of pump issues.
   • How to Check the Pressure Vessel:
     • Turn off the pump using the main switch.
     • Isolate the water supply.
     • Open a tap to relieve any existing pressure in the pump.
     • Unscrew the cap on the schrader valve.
     • Use a tire gauge to measure the pressure.
     • Adjust the pressure according to the pump specifications. For example, if it’s a 2 bar pump, set the pressure to 2.5 bar, and so on.
4. The Importance of Checking Air Pressures: Often, technicians or homeowners overlook checking the air pressures on expansion vessels. Incorrect air pressures can lead to ineffective operation of the pump and other associated problems.
5. Consider the Pressure Switch: After checking and adjusting the pressure vessel, if the problem persists, the pressure switch itself could be the culprit. It might require a closer examination or replacement.

For a visual guide on understanding and troubleshooting issues related to Stuart Turner pumps, several online resources can be helpful. One recommended video tutorial is available here, which provides an in-depth look at diagnosing pump problems.

In Conclusion: Stuart Turner pumps, while reliable, can face operational issues from time to time. By systematically diagnosing the problem – whether it’s related to the pump’s age, the pressure vessel, or the pressure switch – homeowners can find an effective solution and ensure a consistent supply of water in their homes. Regular maintenance and checks, especially focusing on pressure levels, can prevent many of these issues in the first place.
