Upon arrival checked motors, electrical components, and pressures. CUSTOMER SIGNED UP FOR TAP ANNUAL. Replaced UV bulb it was at 2 year limits. Had to use UV bulb from kit because had no bulb replacement for UV pure Air system. I will need 2 bulbs replenished (1 for kit n 1 for backup replacement). Cleared drain line and added Nubrite. Changed filter. Left system in good operating condition.
