Скачать или смотреть Replace Lead Wipe P-Trap Under Sink

Wiping a P-trap with lead is a traditional plumbing technique that involves creating a watertight seal between the P-trap and the waste pipe using molten lead. It's an older method that has been largely replaced by modern solvent-weld or threaded connections, but it's still sometimes used in certain situations or for restoration projects.
Here's a general overview of the process:
Materials and Tools:
Lead: Typically a bar of 60/40 lead alloy
Soldering Torch: To melt the lead
Lead Pot or Ladle: To melt and pour the lead
Caulking Iron or Similar Tool: To shape and smooth the lead
Flux: To help the lead adhere to the pipe
Cleaning Tools: Wire brush, rags, etc.
Safety Gear: Gloves, eye protection, and possibly a respirator
Process:
Preparation:
Clean the surfaces of the P-trap and the waste pipe where the lead seal will be made.
Apply flux to the cleaned surfaces.
If necessary, pack oakum or other material into the joint to create a base for the lead.
Melting the Lead:
Heat the lead in a lead pot or ladle until it melts.
Be careful not to overheat the lead, as this can make it difficult to work with.
Pouring the Lead:
Carefully pour the molten lead into the joint, making sure it fills the space completely.
Use a caulking iron or similar tool to shape and smooth the lead while it's still molten.
Cooling and Finishing:
Allow the lead to cool and solidify completely.
Once cool, inspect the joint for any gaps or imperfections.
If necessary, reheat and reshape the lead to ensure a watertight seal.
Important Considerations:
Safety: Working with molten lead can be dangerous. Wear appropriate safety gear and take precautions to avoid burns or lead exposure.
Skill: Wiping a P-trap with lead requires skill and experience. If you're not confident in your abilities, it's best to hire a qualified plumber.
Regulations: In some areas, the use of lead in plumbing may be restricted due to health concerns. Check local codes and regulations before using this method.
Alternatives:
Solvent-weld connections: These use a chemical solvent to fuse PVC or ABS pipes together.
Threaded connections: These use threaded fittings to connect pipes.
These modern methods are generally easier and faster than lead wiping and don't involve the use of hazardous materials.
If you're considering wiping a P-trap with lead, it's important to weigh the pros and cons carefully and make sure you have the necessary skills and experience. If you have any doubts, it's always best to consult with a qualified plumber.
