## Questions & Answers

**Q: My white washers leak quickly and when I tighten them they get shredded. Any advice? Where can I order replacement washers?**
A: The white rubber ring is used as a substitute for the black rubber ring.
There are two large black rubber rings in the package. You can use black rubber ring instead of white rubber ring operation.

**Q: What size is the O-ring for the bleed valve?**
A: The product comes with 4 small black O-ring for the bleed valve.  The size is about 0.5mm.

**Q: which soda stream valve is this for, old style with extended pin or new style with flush pin?**
A: I was able to use in both types. Be sure to slowly open the valve on the gas cylinder. If you do it too fast on the flush pin, it’ll lock up. You’ll need to then remove the soda canister from the unit, then reseat, and refill again.

**Q: What psi do I fill the cannisters to? Can this be used with a regulator?**
A: My tank is stamped with pressure requirement
