The Viva Skylo 4-in-1 Filling Valve is a highly versatile and universal toilet cistern fill valve designed to be a single solution for nearly any installation requirement. It integrates four key functions into one unit, making it a favorite among trade professionals for repairs and new builds.
The Four Functions Explained
The "4-in-1" refers to the valve's ability to adapt to different plumbing configurations using the components included in the box:
- Bottom Entry Installation: It can be configured for a water supply coming up through the base of the cistern.
- Side Entry Installation: It can be easily switched to accommodate a water supply entering from the side of the cistern.
- 1/2" UK Thread Size: It comes with the standard 1/2-inch BSP thread size used widely across the UK and Ireland.
- 3/8" European Thread Size: It includes an adapter to convert the connection to the smaller 3/8-inch BSP thread, common in European plumbing systems.
Key Features and Benefits
- Universal Compatibility: With both entry options and thread sizes covered, this single product can replace almost any existing fill valve, reducing the need for plumbers to carry multiple variations.
- Water Saving (Delayed Fill): The mechanism delays the main cistern filling process until after the flush cycle is complete, helping to save water and reduce water bills.
- Compact & Adjustable:
- It is height-adjustable (telescopic) to fit various cistern heights, usually between 9 and 14 inches.
- The float can rotate 180 degrees, allowing it to fit into extremely tight or unusually shaped cisterns without snagging.
- Quiet Operation: It is designed for quiet refilling, operating efficiently across a wide pressure range (0.25 to 16 bar).
- Durable Build: It is available in models with either a plastic or a heavy-duty brass shank to prevent cross-threading and ensure longevity.
