How to Install an Air Chamber to Prevent Water Hammer · Step 4 of 6
In this video
Take the old valve assembly to a workbench. Measure all the pipe lengths and fitting placements. Cut new half-inch copper pipes to match these measurements. After cutting, use a reaming tool to deburr the inside of each pipe end. Then, use a pipe cleaning tool to clean the outside of the pipe ends and the inside of all new copper fittings. Apply a thin layer of flux to all cleaned surfaces that will be soldered.
Goal: Plumbing Pipes Installation
- Reaming the pipes after cutting removes burrs and helps ensure a good water flow.
- Thoroughly cleaning the pipes and fittings is crucial for a strong, leak-proof solder joint.

FAQs
This project is rated 'beginner.' What's the biggest challenge, and what unexpected costs should I budget for?
The biggest challenge for beginners is often the soldering, which requires a steady hand and practice. Beyond the listed materials, budget for essential safety gear like a fire extinguisher or bucket of water, heat-resistant gloves, and proper eye protection. The total material and basic tool cost could range from $50-$150 if you need to purchase all soldering equipment.
What are the essential safety precautions I must take, especially when using a torch for soldering?
Always have a fire extinguisher or a bucket of water nearby when soldering, and ensure the work area is well-ventilated to avoid inhaling fumes. Wear appropriate eye protection and heat-resistant gloves to prevent burns. Before cutting any pipes, confirm the main water supply is completely off and the pipes are fully drained to prevent unexpected sprays or electrical hazards.
If I'm not comfortable with soldering, are there alternative connection methods for installing the air chamber?
Yes, if soldering isn't your preference, you can use push-fit fittings, like SharkBite, which don't require heat or special tools beyond a pipe cutter. These fittings create a secure, watertight seal by simply pushing the pipe into the fitting. While often more expensive than traditional copper fittings, they offer a beginner-friendly alternative for quick installation.
What's the most common reason a newly installed air chamber might not stop water hammer, and how do I fix it?
The most common reason is an insufficient air cushion or the chamber being too short. Ensure the air chamber is installed vertically with the capped end pointing upwards, allowing air to be trapped effectively. If water hammer returns, the air cushion may have depleted; you can recharge it by shutting off the main water supply and draining the system to refill the chamber with air.
