## Questions & Answers

**Q: Does this come with the actual ball?**
A: No it doesn’t.  You have to buy the ball separately.

**Q: Does this come with fibre washers to go in the  connection to the water inlet?**
A: no it doesn't what you see in the picture is what you get

**Q: i have a 1/2inch ball valve and want to increase the flow to the cold tank on a combination cylinder would going to 3/4 do this supply still 1/2inch**
A: The supply pipe is still 1/2 inch that will dictate the flow. The primaflow product is good quality but take off the cap that seals the washer and coat threads with Vaseline makes future repair simple

**Q: The large water tank in my attic needs a new part 2 float valve, how can I tell if its a 1/2 inch or 3/4 inch**
A: Without actually seeing it, I would be tempted to buy one of each, then return the one you don’t use. But if it’s on a domestic I would guess it’s 1/2. Hope this is helpful?
