Frequently Asked Questions
What is the difference between this and the standard 380AG fill valve?
This is the boxed retail pack version of the Geberit 380AG, supplied in point-of-sale packaging. The valve itself is the same — bottom entry, Type AG backflow prevention. If you need the side supply version, see the Geberit Type 380AG Side Supply Fill Valve.
Which cisterns is this compatible with?
This fill valve fits all common close-coupled ceramic cisterns as well as Geberit concealed cisterns. It is suitable as a replacement for older Geberit cisterns and exposed or concealed cisterns from many other manufacturers.
What does the delay fill function do?
The delay fill function prevents the cistern from refilling until the flush valve has fully closed. This reduces unnecessary water waste and can deliver measurable water savings depending on flush volume and pressure.
Is this WRAS approved?
Yes — this fill valve meets WRAS Section 2075 requirements and is certified to BS 1212-4:2016.
What connection size does it use?
The valve uses a G ½" bottom supply connection with a plastic threaded nipple.
