he Hydroflo® Inlet Valve is engineered as a high‑quality replacement for most plastic and ceramic cisterns, both exposed and concealed. Its compact delay‑fill design saves water by ensuring the cistern only begins refilling once the flush cycle is fully complete.

A unique side‑inlet float arm prevents detachment, delivering long‑term reliability in demanding installations. The valve also incorporates an integrated backflow prevention device, making it one of the safest and most dependable options available. Finished with a durable brass tail, the Hydroflo® Compact Float Valve offers robust performance across a wide range of cistern types.

Frequently asked questions

Our current range of fully compliant Hydroflo inlet valves, come pre-fitted with a flow regulator, so no need for a flow restrictor. Our previous range were supplied with a flow restrictor, which needed to be removed for water pressures below 1.5 bar. As these inlet valves operate on an equilibrium principle, which uses the supply water pressure against itself to operate the valve they are suitable for use on water pressures between 0.1 bar and 14 bar.
