Read the pump nameplate first
Horsepower alone isn't enough. Note frame size, voltage, speed count and discharge orientation — those four values identify a direct replacement.
About this category
Spa Equipment at BidBuild Marketplace
Most spa failures come down to four parts: the pump, the heater element, the control pack or the topside panel. We stock all four across the major platforms, plus jets, blowers, ozonators, pressure switches and unions.
Listings carry the voltage, amperage, plumbing size and pack compatibility so a replacement drops in without re-plumbing the skid.
Match by pack, not by guess
Filter by control system so the topside, heater and pump you order actually speak to each other.

Buying guide
How to choose spa equipment
No heat is usually flow
Before replacing a heater, check the filter, pressure switch and air lock. Most heater assemblies fail because flow dropped, not because the element died.
Replace unions and gaskets together
New pump, old gasket is the most common callback. Union kits cost a few dollars and prevent a second trip.
Spa Equipment questions, answered
How do I identify my spa pack?
The model and part number are printed on a label inside the equipment door, on the control box lid. That number matches directly to compatible topsides and heaters.
Can I replace a two-speed pump with a variable-speed one?
Only if the control pack supports it. Otherwise the pack will only ever call for high or low speed.
Do these parts fit any brand of spa?
Most spas use a handful of shared OEM platforms. Each listing names the compatible systems so you can confirm before ordering.
