Buying Guide
What should you consider when choosing a spa air control valve?
- Valve type: Top draw vs bottom draw affects installation space and accessibility. Choose based on your spa’s valve body and service layout.
- Connection size: Most spa air controls come in 1″ fittings. Confirm the diameter and thread style for a proper seal with your plumbing.
- Top-access vs glue-in: Top-access is easier for replacement; glue-in options may require more precise alignment during installation.
- Finish and color: Gray, white, or other finishes help match spa interiors. Choose a color that blends with your spa shell or control panel.
- Material durability: Look for corrosion-resistant materials suitable for humid spa environments and frequent temperature changes.
- Brand compatibility: Some valves are designed for Waterway, HydroAir, BWG/HAI, or Cal Spa systems. Verify compatibility with your existing spa model.
How to measure for a replacement
- Identify valve size: Most common is 1″ nominal size; measure the inlet/outlet diameter if unsure.
- Check draw style: Determine if your current valve is top-draw or bottom-draw to select a compatible replacement.
- Inspect fittings: Confirm if your spa uses glue-in or threaded connections and whether you need a notched top or standard top-access design.
FAQ
