AquaStar - Main Drain Anti-Vortex Suction Cover with Screws - 6HP101

AquaStar – Main Drain Anti-Vortex Suction Cover with Screws

The AquaStar 6HP101 is a replacement hot tub suction outlet cover, also called an anti-vortex cover, supplied with its screws. It is a spare part for the HydroAir “Main Drain” assembly drain plug (10-6012), an assembly that has not been on sale since 2008. Choose it when the grille on your Balboa / HydroAir main drain needs replacing and you want to match the original dimensions.

Compatibility with the HydroAir Main Drain assembly

This spa suction grille is a spare part for the HydroAir “Main Drain” assembly, part number 10-6012. The number 30-6011 is also listed for HydroAir against this cover.

Because the complete drain assembly is no longer sold, this cover is useful if your existing grille is damaged or missing and the rest of the drain fitting is still in place. Compare the numbers above with those of your own drain before ordering.

Dimensions and screw spacing

Check these measurements against your current suction cover to make sure you order the right replacement:

• Outside diameter: 152 mm
• Inside diameter: 145 mm
• Thickness: 40 mm
• Distance between screws: 72 mm, measured across the cross on the face of the grille

The centre of each screw is 36 mm from the centre of the grille. Measuring the screw spacing is a quick way to confirm that the cover matches your drain.

What is included

The AquaStar 6HP101 suction grille is supplied with its screw set, so you do not need to source fixings separately.

How to choose the right drain cover

Spa drain covers can look similar, so rely on the part number and the measurements rather than appearance alone. Look for one of these numbers on your old cover or on the documentation of your spa:

• AquaStar: 6HP101
• HydroAir: 10-6012
• HydroAir: 30-6011

If your drain has a different diameter or a different screw spacing from the figures above, this cover is not the right part for it.
