The Baxi Multifit Easy-Fill 2 Filling Link is a permanently installed, spring-loaded valve assembly that lets a Baxi combi boiler be re-pressurised in seconds, with no tools, no temporary hoses, and no engineer call-out. Fitted directly beneath the boiler between the cold mains inlet and heating return isolation taps, it stays connected for the life of the appliance, so the householder simply holds the green lever until the pressure gauge reads correctly. Baxi introduced the Easy-Fill design specifically because low-pressure faults were one of the single biggest sources of avoidable warranty and service calls - this link removes that friction for good.
Informational: This is the second-generation Easy-Fill link - Baxi's compatibility documentation lists it separately from the earlier Multifit Rigid Filling Link (7689034) and the standalone Multifit Filling Loop Kit (248221). Always match the part number on your boiler's spares list rather than the product name alone, as several similarly named filling accessories exist across the Multifit range.
Compatibility caveat: Confirm the exact boiler model and revision against your appliance's spares documentation or Baxi's technical support before ordering. Filling link fitments have changed across Multifit generations, and an incorrect match can result in leaks at the isolation tap connections.
Key Features
Permanent Installation
The link stays fitted beneath the boiler between the cold mains and heating return isolation taps, so there's never a temporary loop to fit, remove, or lose.
Spring-Loaded Green Lever
Holding the spring-loaded lever opens the fill path instantly - release it and the link closes itself, with no valves to manually shut afterwards.
Tool-Free Operation
Homeowners top up pressure with no spanners, keys, or hoses - just hold the lever until the gauge needle reaches the green zone.
Air Break Protection
A built-in air break on the link body prevents backflow into the mains supply - it must never be capped or connected to pipework.
Retrofit or New-Build Ready
Can be fitted at initial installation or retrofitted to an existing boiler after draining and relieving system pressure.
Genuine Baxi Build Quality
Supplied with O-rings, fibre washers, and clip nuts for a complete, engineer-standard fitting kit straight from the box.

Frequently Asked Questions
Can the Easy-Fill 2 link be left permanently connected to my boiler?
Yes. Unlike a temporary filling loop, the Easy-Fill 2 is designed and tested to remain connected after use. It should be fitted between the cold mains inlet and heating return isolation taps and left in place for the life of the boiler.
How do I use it to top up my boiler pressure?
Open the cold mains and heating return taps, then hold down the spring-loaded green lever until the pressure gauge needle reaches the correct green zone (typically 1-1.5 bar cold, check your boiler's manual for the exact figure). Release the lever and it closes automatically.
Can this be fitted to an existing boiler, or only at installation?
Both. It can be fitted at the time of installation or retrospectively to a boiler already in service. Retrospective fitting requires the system pressure to be relieved and the boiler drained first.
Is this the same as the standard Multifit Filling Loop?
No. Baxi lists the Easy-Fill 2 (7783329) as a separate, newer part from both the Multifit Rigid Filling Link (7689034) and the Multifit Filling Loop Kit (248221). Check your boiler's spares documentation for the correct part number before ordering.
What's included with the Easy-Fill 2 kit?
The kit includes the valve assembly, O-rings, two fibre washers, adaptor clips, a boiler front-panel label, and full fitting instructions.
