Hi All, this is Ken from Livermore, CA. We are 30 miles due East of San Francisco Bay and somewhat in the shadow of Napa and Sonoma, but have great wines and a long winemaking history dating from the mid 1800's. I purchased a home here in 2009 with a ~1500 gallon in-ground spa with a waterfall feature. I needed to move the equipment pad to make room for an outbuilding, which prompted a search to upgrade the Hayward equipment that now has to be at least 25 years old. Kudos to Hayward for their build quality, at least at that time. Happy to find this site, and will be posting questions soon. Also happy to share what I learn along the way.
