A consistent and reliable water supply is essential for hot-water cylinders to fulfill their purpose of providing hot water for your daily needs. However, issues with water supply can occur, causing inconvenience and discomfort. In this blog post, we will explore the common causes of a lack of water supply in hot-water cylinders, discuss the signs that indicate a problem, and provide practical solutions to diagnose and resolve the issue.
Signs of a Lack of Water Supply:
- No hot water: The most obvious sign of a lack of water supply in your hot-water cylinder is the absence of hot water when you turn on the taps or shower.
- Reduced water pressure: If you notice a significant drop in water pressure from the hot-water outlets, it may indicate a problem with the water supply to the cylinder.
- Strange noises: Unusual sounds, such as banging or gurgling noises coming from the hot-water cylinder, can be indicative of a water supply issue.
Possible Causes and Solutions:
- Closed isolation valve: Check if the isolation valve on the cold-water supply pipe leading to the hot-water cylinder is fully open. If it is closed or partially closed, turn it fully open to restore the water supply.
- Airlock in the pipes: Air can sometimes get trapped in the water pipes, leading to a lack of water flow. To release the airlock, turn on the affected hot-water taps and allow them to run for a few minutes until the water flows smoothly.
- Blocked or faulty pipes: Inspect the pipes leading to and from the hot-water cylinder for any blockages or leaks. Clear any obstructions or replace damaged pipes as necessary. It’s advisable to seek the assistance of a professional plumber for complex pipe issues.
- Faulty pressure reducing valve: A malfunctioning pressure reducing valve can restrict water flow to the hot-water cylinder. Consider calling a professional plumber to inspect and replace the faulty valve.
- Problems with the mains water supply: In some cases, the lack of water supply may be due to issues with the mains water supply in your area. Contact your water utility company to inquire about any known disruptions or maintenance activities.
When to Seek Professional Help:
- While some of the above troubleshooting steps can be performed by homeowners, it’s important to know when to seek professional assistance. Consider contacting a licensed plumber in the following situations:
The issue persists even after performing basic troubleshooting steps.
You suspect a complex problem or significant damage to the water supply system.
You are uncomfortable handling plumbing repairs or lack the necessary expertise.
A lack of water supply in hot-water cylinders can be a frustrating problem that disrupts your daily routine. By understanding the signs of a water supply issue and following the suggested solutions, you can diagnose and resolve the problem in many cases. However, for complex issues or situations where professional expertise is required, it is recommended to seek the assistance of a qualified plumber.
