What it is
The Fluidmaster B661AT1/2B is a bottom entry fill valve with a brass shank, manufactured by Fluidmaster. It is fitted inside a toilet cistern and refills the cistern with water after a flush. The bottom entry design takes the supply connection through the base of the cistern rather than the side wall.
Before you order
- Confirm the cistern uses a bottom entry inlet, not a side entry inlet.
- Check the existing valve part number and shank arrangement against B661AT1/2B.
- Confirm the shank thread matches the cistern inlet before fitting.
