Review: all good - spot on very good, easy to fit
Review: For a compact toilet..... - Needed the above float valve to replaced the used one that an emergency plumber used when we had a pipe leak. He replaced one like the above with a completely different make, so getting a replacement washer was a chore for the float arm, when I have loads for the SIAMP one (the float arm washers tend to have a life of about 3 years before wearing out causing the toilet cistern to overflow). Nice concise instructions, a breeze to install, up and running in half an hour.... However, it came in a bag, not a box so the float arm popped out of the clip so it caused it to stick. This is not easy to see, but I clipped it back in and the float worked, switching the water off to the system, so no overflow. Tools needed: Towel and sponge to soak up any water Screwdriver to turn off the water supply to the cistern (all toilets should have a stop valve) Adjustable spanner or grips And that's about it. Does the job for these bottom fill compact cisterns.

## 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.
