Changing the taps and tees/drop lines should get us back to year 1 production rates. We are also testing check valve taps this year to see if there are any benefits to this.
Let me know if you see a more pronounced production rate with check valve taps v. regular ones, I would be interested in hearing! Hopefully your new evap comes soon especially since you sold your old one!
