I didn't install it, but I've worked on it several times after the installer quit trying to fix it. He spent the first three months working on something at least twice a week, had to completely redo several parts of the plumbing, replace all the low-pressure regulators, all the tubing fittings, and the first time I went in there the service guy showed me drawers full of spare parts they had to keep on hand, probably $3000 in solenoids and injectors that they have to change on a regular basis.Thank you for the reply. When did you install the equipment?
