## Questions & Answers

**Q: Have you fixed your thread fitment issue?**
A: I used a standard NPT brass nipple instead of the one included with filler valve. Used bunch of heavy duty Teflon tape and it sealed well. No leaks after months of service.

**Q: Temperature max?**
A: No specific answers. To be safe I would just figure the maximum theoretical ambient air temperature plus 10-15°. So on 110°F day in the sun I’d figure 125°f as an extreme threshold

**Q: What is the flow rate? How many gallons per minute will it flow?**
A: I have no idea. I have it dripping from a holding tank

**Q: Is the plastic BPA  free ?**
A: Yes
