Joining PVC pipes: Why professional pipe lubricant is better than dish soap
Installing a drainage system seems simple until you encounter resistance when inserting the spigot end of the pipe into the socket. Many installers, looking for quick solutions, reach for dish soap. But is this a safe shortcut? We explain why choosing a professional armack assembly paste is an investment in long-term leak tightness.
Why dish soap is a trap
Although dish soap provides temporary slip, its chemical composition is not neutral to the plumbing system:
- Seal degradation: Detergents contained in dish soap leach plasticizers from the rubber. The result? The seal hardens, deteriorates, and loses its sealing properties.
- Risk of delayed leaks: A joint that seems leak-tight today may start leaking a year later, which means massive repair costs for pipes buried in the ground or concealed within walls.
The advantage of professional armack lubricants
By using products such as armack Silicone Lubricant or STANDARD Pipe Joint Lubricant, you guarantee:
- Rubber protection: Our compounds are chemically neutral to seals, prolonging their lifespan and maintaining their elasticity.
- Easy installation and adjustment: The paste allows for precise pipe alignment and, if necessary, facilitates easier disassembly or angle adjustments later on.
- Certifications and safety: Purpose-made products are specifically tested for sanitary plumbing systems, ensuring peace of mind for both you and your customer.
In summary, a dedicated PVC pipe lubricant is a much safer solution and ensures better joint quality than dish soap. Dish soap should only be used as an absolute last resort in emergencies.
Practical tip: How to join pipes correctly
- Clean the pipe ends of sand and dirt.
- Apply a thin layer of armack pipe lubricant to the spigot (plain) end of the pipe (not to the seal!).
- Insert the pipe fully into the socket until it bottoms out, and then pull it back by about 10 mm to allow for thermal expansion.
