Review: Seems to be working well so far - I got this AR valve to remove air bubbles that can show up in my domestic water supplier's lines when they do work on the system. I have a boost pump as my home is elevated from the normal, gravity-fed portions of the system. Air in the line can shut my pump down, at best, and can do it damage, at worst. Installation of this AR valve went easily. The initial air in the valve escaped when pressure was restored. And the valve closed when it filled with water. No leaks at ~50-75 psi.
Review: Product WARNING - The product description says stainless steel. But upon arrival of the valve there is a warning that the product contains chemicals known to the state of California to cause Cancer, Birth defects or reproductive harm. Safety Code 25249.6. Now I cannot use this product for my water source.

## Questions & Answers

**Q: Is this also a Vacuum valve or only an air release?**
A: From the looks it is both.

**Q: will this valve let air into the system if there is not water present to lift the float?**
A: Yes, it will but take in mind that the orifice is 1/16".   When there is no water in the line, the float is down and the valve is open, air can go in thru the 1/16" orifice.  I you require larger amounts of air to go into the pipe, you might need a combination air valve.    Check this listing  https://www.amazon.com/dp/B07GSRJ5M9?ref=myi_title_dp
