"Very professional and helpful! We live on base where the water is very harsh on your skin and not drinkable. The system they installed is great and very affordable. They even installed our system the very next day. I would highly recommend them."

“This is ABSOLUTELY THE BEST WATER SERVICE/SYSTEM IN SAN DIEGO! We love our water softener, and our most recent installation of the water purifying spout at our sink is FANTASTIC! No more purchasing of expensive water bottles every week! Your people are super friendly, courteous, professional, and EFFICIENT! You’ll be glad you called them!”

Just realized I've never reviewed this company ... and they're awesome!! Been using their soft water delivery service for over a year, and it's so easy. They switch out the tanks on a schedule and you don't have to deal with salt or any of the maintenance. I had a small leak one time, and they came out to fix it the same day. Can't recommend them highly enough!!
