## Questions & Answers

**Q: can i insert these directly into my 1/2" tubing?**
A: Yes you can but it is not self puncher type. You'll need to punch hole in tubing first.

**Q: Black is usually 1 gal per hour. What is the flow rate of this totally green dropper?**
A: 2 gallons per hour for the green ones.   
1 gallon for the black or blue ones. 
1/2 gallon for the red or orange ones.

**Q: what water pressure should be used with these droppers?**
A: Most information seems to be 25 PSI, I'm using them at 30 PSI and they are working without problems.

**Q: What filter you recommend to block the particles that could clog the drippers?**
A: There is a fine meshed in line screen filter that fits inside the hose fittings used for the drip hose. This traps anything large enough to plug a dripper.
