Regular maintenance and flushing of the water system can also help ensure the quality and safety of the drinking water.

Q: Is it OK to bury brass fittings?

A: It will not corrode when it is in contact with soil or water. However, Brass fittings are non-ferrous metals, which means that they cannot be electroplated. When buried, these fittings will rust and corrode over time.

Q: Why do brass fittings turn green?

A: The green layer you see is called tarnish and forms when brass is exposed to the carbon and sulfur dioxides in the air. It's basically a thin layer of corrosion that forms and it can only be eliminated with a thorough cleaning which requires you to remove some of the surface and patina of the piece.

Q: Can I use a brass fitting in PVC?

A: Yes, it is possible to use a brass fitting in conjunction with PVC pipes. However, it requires the use of an appropriate transition fitting to connect the two different materials. These transition fittings are typically made of brass or another compatible material and have threads or solvent weld connections that can be used to join the brass fitting to the PVC pipe. It is important to ensure that the transition fitting is designed specifically for this purpose and is compatible with both the brass fitting and the PVC pipe.

Q: What is the white powder on brass fittings?

A: Dezincification is an electrochemical process and type of metal corrosion in which zinc, a component of brass, is released from brass. When zinc is released from brass, it is often in the form of zinc oxide, which may be visible as a white sediment.

This can lead to leaks or the fitting becoming unusable. Cracking or splitting: Brass fittings can crack or split if excessive force is applied during installation. This is particularly a risk when using smaller or more delicate fittings. Compression fittings can fail: Over-tightening compression fittings can cause the ferrule (the ring that compresses onto the pipe) to deform or break. This can result in leaks or a weak connection. Distorted or crushed pipe: Applying too much force while tightening a brass fitting onto a pipe can distort or crush the pipe, leading to leaks or a compromised plumbing system. To avoid these issues, it’s important to follow the manufacturer’s instructions and recommended torque specifications for tightening brass fittings. It’s also helpful to use thread sealant or tape, when appropriate, to ensure a proper seal without excessive force. Applying too much force can cause damage and compromise the integrity of the fitting and plumbing system.

Q: Will a brass fitting stop leaking?

A: A properly installed brass fitting should not leak, as they are known for their durability and resistance to corrosion. However, if a brass fitting is not installed correctly, damaged, or if there is damage to the pipe, it may result in leaks. To address a leaking brass fitting, it is important to identify the cause of the leak and take appropriate action, such as re-tightening the fitting, applying thread sealant, replacing the fitting, or repairing the damaged section of the pipe. Promptly addressing any leaks is crucial to prevent water damage and maintain the integrity of the plumbing system.

Q: Can you fit brass compression fittings on plastic pipe?

A: Brass compression fittings are typically designed for use with copper pipes. While it is technically possible to use brass compression fittings on plastic pipes, it is not recommended. Plastic pipes, such as PVC or PEX, have different expansion and contraction rates compared to copper pipes. This can lead to issues such as leaks or cracks in the plastic pipe when used with brass compression fittings. It is generally best to use fittings that are specifically designed for use with plastic pipes. These fittings are made of materials that are compatible with the plastic pipe and will provide a secure and reliable connection.
