Understanding the Causes of Water Hammer
Before deciding whether to tackle a water hammer issue on your own or call a professional, it’s important to understand the underlying causes of this plumbing problem. Water hammer can occur for a variety of reasons, including:
- Fast-closing valves: When a valve is shut off abruptly, it causes a sudden change in water flow, leading to a water hammer effect.
- Loose pipes: Over time, pipes can become loose or unsecured, allowing them to shake and vibrate when water flows through them.
- High water pressure: Excessive water pressure can intensify the force behind the water hammer effect.
- Waterlogged air chambers: Air chambers are designed to absorb the shock of sudden water flow changes. However, if they become waterlogged, they no longer effectively dampen the water hammer effect.
With these causes in mind, let’s examine whether you can address a water hammer issue on your own or should seek professional assistance.
DIY Methods for Remedying Water Hammer
In some cases, you may be able to resolve a water hammer issue without professional help. Here are a few DIY methods you can try:
- Adjusting water pressure: If your water pressure is too high, it can be a major contributor to water hammer. Consider adjusting your water pressure regulator or installing a pressure-reducing valve to bring the pressure down to a safe level.
- Securing loose pipes: If you suspect loose pipes are causing the water hammer, inspect your plumbing system for any unsecured pipes. Tighten pipe brackets or add additional support to prevent them from shaking and vibrating.
- Draining air chambers: Waterlogged air chambers can be a common cause of water hammer. Shut off the main water supply, open all taps in your home to drain out any remaining water, and then turn the water supply back on. This can help clear any trapped air and restore the functionality of the air chambers.
- Installing water hammer arrestors: Water hammer arrestors are devices designed to absorb the shock of sudden water flow changes. These can be installed at specific problem areas, such as near washing machines or dishwashers, to help alleviate the water hammer effect.
When to Seek Professional Help
While the aforementioned DIY methods can be effective in many cases, there are situations where calling in a professional plumber is the best course of action. Consider involving a professional if:
- The problem persists: If you have attempted DIY remedies to address water hammer but the issue persists, it may indicate a more complex problem that requires professional expertise.
- Accessing hidden pipes: If the troubled pipes are hidden within walls or other inaccessible areas, it can be challenging to address the water hammer issue without causing further damage. In such cases, a professional plumber can utilize specialized equipment to diagnose and fix the problem.
- Inadequate plumbing knowledge: If you don’t have the necessary plumbing knowledge or experience, it is best to leave the resolution of water hammer to a professional. They have the expertise and tools required to assess the situation accurately and execute the appropriate solution.
- Potential for further damage: Water hammer can cause damage to pipes, fittings, and appliances over time. If you suspect any significant damage or are concerned about potential long-term consequences, it is advisable to consult a professional plumber who can conduct a thorough evaluation and provide appropriate solutions.
Water hammer can be a frustrating and potentially damaging plumbing issue. While some cases of water hammer can be resolved through DIY methods like adjusting water pressure, securing loose pipes, draining air chambers, or installing water hammer arrestors, there are situations where professional assistance is necessary. If DIY remedies fail to solve the problem, the pipes are inaccessible, you lack plumbing knowledge, or there is a risk of further damage, it is best to consult a professional plumber who can diagnose and address the water hammer issue effectively, ensuring the long-term functionality and durability of your plumbing system.
