This collection brings together the most frequently purchased spa components across multiple categories for convenient one-stop ordering: Waterway EX2 therapy pumps (2.0SPL and 3.0SPL, 230V, 2-speed, 48-frame, 2\" connections) are high-performance replacement pumps for the jet circuits in residential hot tubs — the 2-speed design allows quiet, energy-efficient low-speed operation for light use and full-power high speed for therapy. The EX2 is one of the most widely compatible therapy pump platforms for residential spa replacement. The Vico Power WOW bath pump (1.0hp, 115V, single-speed) is a compact, quiet pump used in whirlpool bath and smaller portable spa installations. The Laing E-14 circulation pump is a whisper-quiet, low-power circulation pump (approximately 40% lower power consumption than standard circ pumps) used in spa filtration and heating systems that run the circ pump continuously — the low wattage makes it well-suited for 24/7 operation. The Filbur filter cartridges (100 sq ft and 155 sq ft, Microban antimicrobial) are replacement cartridges for the two most common large-format spa filter housings. The BluWater bromine generator (115V/230V, up to 1,500 gallons, with topside controller) provides automatic bromine generation from sodium bromide salt — delivering consistent bromine sanitation without handling tablets. The Zodiac Nature2 G Vessel (W25904, 2\" professional in-ground) is the full mineral sanitizer vessel for in-ground spa and pool installations.

When ordering spa pumps, confirm the horsepower rating (service factor HP vs. nameplate HP), voltage (230V for most residential therapy pumps), frame size (48-frame is standard for residential spas), and connection size (2\" for most therapy pumps, 3/4\"–1\" for circulation pumps). Circulation pumps and therapy pumps serve different functions and are not interchangeable — therapy pumps move high volumes at high pressure for jets; circulation pumps move low volumes continuously for filtration and heating.
