Ariston 990737 Filling Loop Pipe

component used in Ariston heating systems, such as boilers, to facilitate the filling or re-pressurizing of the system. Here’s a detailed overview of its functions and maintenance:

• System Refill:
  • The filling loop pipe allows you to add water to the heating system when needed. This is often necessary when the system pressure drops, which can happen due to leaks or other issues.
• Pressure Regulation:
  • It helps to maintain the correct pressure within the heating system, which is crucial for efficient operation and preventing damage. Proper pressure ensures that the system operates effectively and that hot water or heating is distributed properly.
• Safety:
  • The filling loop pipe typically includes valves that control the flow of water into the system. These valves help prevent overfilling and manage the system pressure safely.
