Full details

It serves as the bridge for replenishing system pressure, ensuring your boiler operates within optimal parameters for efficient heat distribution.

FAQs
Which legacy part numbers does the 3.015849 replace?
It replaces 3.013129, 3.014733, 6.5629220, and 6.5633620.
Do I need a plumber to install this?
While it can be a straightforward swap for experienced users, it involves water-carrying components and we recommend professional installation to ensure system safety and leak-free operation.
What is the correct operating pressure for my boiler?
Most Alpha boilers operate optimally between 1.0 and 1.5 bar. Always consult your boiler's manual for the specific recommended range.
Is this an authentic Alpha part?
Yes, this is a genuine replacement part manufactured to Alpha's technical standards.
Can I leave the filling loop connected permanently?
It is generally recommended to remove the filling loop or ensure both isolation valves are tightly closed after use to prevent accidental system over-pressurization.
Troubleshooting
Boiler pressure continues to drop after using the loop
Check for leaks in radiators or valves. If no external leaks are found, the internal pressure relief valve or the filling loop itself may require professional inspection.
Water will not flow through the loop into the system
Ensure the mains water supply valve is fully open and the loop is properly connected. Verify there are no blockages or trapped air in the connection path.

Setup, Compatibility & Care
Installation should be performed by a competent person or qualified heating engineer. Before beginning, ensure the boiler is switched off and the system is cool. Always isolate the mains water supply before attempting to remove the old loop or install the 3.015849 replacement. During installation, ensure all seals are seated correctly to prevent weeping. Regular care involves checking the filling loop area for any signs of dampness or corrosion during your annual boiler service. Always cross-reference your specific boiler serial number with the manufacturer's parts list to confirm that the 3.015849 is the correct replacement for your model, as installation in an incompatible system can lead to leaks or mechanical failure.
