Hayward SP1048AVH Main Drain Bumper For AV Drains
The Hayward Main Drain Bumper (Model SP1048AVH) is an accessory designed to fit over Hayward’s 8-inch anti-vortex (AV) main drain covers. Its primary purpose is to prevent automatic suction-side pool cleaners from becoming stuck on the drain cover, thereby enabling the cleaner to operate freely and cover the pool effectively.
Key Features
A bumper/adapter that hooks or sits across the main-drain cover, creating a raised barrier so the cleaner’s wheels or skirt don’t grab the cover lip.
Designed specifically for the older Hayward 8″ AV-style main drains (pre-VGB compliant era).
Easy to install — simply attach over the existing drain cover without major plumbing changes.
Helps improve pool cleaner movement and prevents stoppage or cycling issues caused when the cleaner latches onto the drain cover.
