## Questions & Answers

**Q: What size is the thread at the bottom where the water comes in please, ive measured mine and its about 20mm**
A: 1/2 thread

**Q: does this replace the inlet valves with the ballon the end?  so no need for the ball float**
A: There is no need for a ball float. The float is the big plastic piece and its position can be adjusted. This inlet valve would normally replace an inlet valve with ball float, given that the basin dimensions can accommodate it.

**Q: Is the inlet 1/2"bsp (21mm) or is it 3/8" bsp (16.67mm)?**
A: It says on the inlet float valve it`s 1/2in.. 15mm plastic.

**Q: What’s the outside diameter of the bottom screw thread part?**
A: I`d say a Quarter of an inch. You  will easy see when you take the old one off.
