## Questions & Answers

**Q: Can this be used in place of a capillary restrictor?**
A: Yes

**Q: On both I can blow into from both sides and air pass through, are both damaged?**
A: Not a direct answer but one of the two I received failed after a few weeks; upon removal I was able to pass air thru both sides.  I did not test the new one (should have), but it seems to be working fine.

**Q: vendor higher CC number means more resistance or less resistance?**
A: Higher number means less flow resistance (higher waste water flow to the drain).

**Q: Does it fit a 1/4” o.d. or i.d. hose?**
A: 1/4" OD
