- Comes with Instruction manual
- Turn off water supply to toilet cistern at storage tank in loft or isolator valve if mains fed. Disconnect pipe work and remove old valve from toilet cistern. Place sealing washer on threaded shank of valve with cone facing down. Position valve in toilet cistern, passing threaded shank through hole in cistern to determine if valve height needs adjusting. Fluidmaster 400-series valves are height adjustable. To adjust the height, remove from cistern and twist threaded shank in or out of the valve body. A clicking noise will be heard on some models. This is normal. The valve height should be adjusted so that the critical level mark on the valve body is located at least 25mm above the overflow pipe. Do not move lock ring, it holds the valve body and shank together under pressure. Do not interchange body with old shank as leaking can occur. Install valve in cistern. Start to thread back nut onto threaded shank so the shank protrudes through the cistern enough to enable tap connector to fit neatly. Do not tighten back nut at this stage. When position is correct and before tightening back nut, reconnect water supply to valve to make sure fibre washer is sealed correctly. Hand tighten connector, do not over tighten. Now tighten back nut, do not over tighten. Turn on water supply.

Bottom entry fill valve
This unit fits most cisterns. Easy to adjust for fill level
BatMac - 5 / 5 - 29/07/2026
Easy to fit and adjust - have made repeat purchase
Good quality, effective seals and very straightforward to adjust. Have them working well in both low and full pressure locations
BatMac - 5 / 5 - 22/07/2026
Effective, easy to adjust
This is a compact device, especially suitable for a narrow cistern. Adjustment is very obvious and the seals are effective - leak-free for each of the three toilets I have refurbished so far. Suitable for both low and high pressure supply.

A good reasonably priced product
Easy to fit and adjust. Clear concise instructions. A very good, reasonably priced product. I would have preferred the equivalent product with the brass fittings but my local store was out of stock. This, though, was a very good alternative.
