Main drain selection for Virginia Graeme Baker Pool and Spa Safety Act compliance
Evoqua offers a variety of Lawson Aquatics® main drain solutions.
The Virginia Graeme Baker Pool and Spa Safety Act (VGBA) was passed to protect and save lives, and we understood it was imperative to engineer a new certified main drain that was inexpensive, easy to install, and yet maintain a high flow rate. The result was the SuperFlow™ domed main drain/grate. NSF and IAPMO certified as well as ASME LISTED, SuperFlow™ grates are the leading choice for retrofitting your main drains or constructing your new pool.
All sumps and drains must be inspected and certified before a facility can open. We were the first to offer an all-in-one 18″x18″ sump and main drain, the SuperSumpTM Main Drain System, that is ASME-2017 LISTED. Featuring a solid one-piece, injection-molded unit, it’s substantially less expensive than fabricated PVC sheets and stainless steel and avoids the need for field inspection and the labor of building concrete sumps.
We can also provide standard-size fiberglass main drain sumps with unblockable PVC grating for areas 18"x36" and larger.
Each 18" x 18" grate tile offers a 54% open area with the highest flow rate of 1040 GPM (SuperFlow™ Frame and Grate). Flexible plumbing locations and sizes configured and customized to your piping schematics. Connections can either be threaded, flanged or couplings.
The VGBA also affects how field-built concrete sumps are fabricated. Our answer is to fabricate larger, custom-sized sumps and unblockable drains (18″x36″, 18″x54″, 18″x72″ and larger). All of which are ASME-2017 compliant.
Our main drains meet the industry’s most stringent testing requirements. Dual certified by both NSF and IAPMO R&T to current SOFA/VGBA compliance, our main drains ensure both quality and enhanced safety for your aquatics facility.
