GROHE 43537000 Dally-Fvent filling valve for 6-litre concealed cisterns

What matters most

For a concealed cistern that needs a replacement filling valve, the GROHE Dally-Fvent 43537000 is specified for 6-litre cisterns. Its stated height is 260 mm, with a DN 10 connection thread and 18 mm thread length. These details help you compare the valve with the cistern and connection before choosing a replacement, rather than relying on the product name alone.

The valve is an original GROHE spare part, with a chrome finish and a single port. The outlet connection is 3/8". For a repair focused on the filling component, this is a more targeted choice than purchasing a complete flush mechanism, a complete mechanism is the broader route when other parts of the cistern also need attention.

Getting the most from it

Use the stated cistern capacity and connection measurements as practical reference points when selecting the part. The DN 10 thread, 18 mm thread length and 260 mm height are especially useful for comparing the replacement with the existing valve. The listed 3/8" outlet connection provides another detail to match during selection.

As a filling valve, its role is to let the cistern refill after flushing. This makes it relevant when the part being replaced is the valve responsible for filling, rather than the flush mechanism as a whole. Checking the existing component and the cistern specification against the stated measurements helps keep the choice focused on the part needed.

Best use cases

This valve is intended for flush-mounted cisterns with a 6-litre capacity. It suits a repair where the filling valve is the component in focus and the existing arrangement corresponds to the stated connection and dimensions. For example, when planning a cistern repair, compare the old valve’s thread and height with the DN 10, 18 mm and 260 mm specifications here before selecting the replacement.

It suits you if you need an original GROHE filling-valve spare part for a compatible concealed cistern and want the key fitting measurements clearly identified. The chrome finish also makes the product details easy to distinguish when comparing replacement components.
