6 Keys to Good & Easy Spa & Hot tub Care
(it's not just chemicals)

Whether you have an inground spa (shown below) or portable/movable spa or wooden hot tub, they all essentially work the same:

• There's a spa body with an interior surface of vinyl, plaster, tile, fiberglass or a combination of these materials.

• Spa Water is drawn into the filter system (blue lines) from the skimmer & main drain

• Water comes into the filter system thru the 3-way valve (if equipped) & into the pump / motor

• Water travels into the filter (typically Cartridge) where fine dirt & debris are removed

• After the filter, the clean or cleaner, filtered water goes thru the heater (usually electric, especially on portable/movable spas with skirts that are self contained)

• Filtered & heated water returns to the pool (red lines) thru the return jets

• Air is typically mixed with or injected into the jets through the Venturi control

• Air is blown through or bubbled through the usually separate air system through holes in the bottom of the seating area and/or floor
