## Questions & Answers

**Q: Do you have a restrictor that is rated at 300mL/min?  If not, what is the closest and what is it's flow rate in mL/min?**
A: It depends on the gallons per day, reverse osmosis membrane. There are numerous videos on UTube to educate yourself on your own particular application.

**Q: My membrane has a 90 degree angle connector with 1/4 inch plastic tubing  that leads to the drainline.  Is this where the capillary is inserted?**
A: Great Question!
You remove the tubing from the connector fitting that connects to the drain line, then insert the flow restrictor into that drain tubing, and reconnect the tubing to the 90 degree fitting.
