Model # WG1154AVPAK2
Deluxe Main Drains with Adjustable Plaster Collar (Concrete)
Hayward main drains set the standard in quality and value. These heavy-duty drains are injection-molded of ABS, which resists chemical attack that leads to "yellowing".This Hayward main Drain can be used on Residential or Commercial applications; also new construction or replacement covers. Please note that Hayward now offers these only as a 2-pack due to regulations that require pools to have two main drains.
We must retrofit our pool to be compliant with the Virginia Graeme-Baker Act. Is this main drain suitable to install so I do not get fined and to keep my pool safe?
Yes , this pool main drain is VGB compliant and should be used on concrete pools with 2" plumbing. if you require a drain of this type with 1-1/2" plumbing we suggest the WG1153AVPAK2 2-Pack.
What is the diameter between the centers of the screw holes?
According to Hayward, the diameter from center to center is 6".
How is the drain opened & closed? Will this also work in a concrete spa?
Yes this would work in a concrete spa, you would open and close the suction of the main drain by using a Jandy Valve which you may view or purchase here http://www.inyopools.com/valves_jandy.aspx You would plumb the Jandy valve into your plumbing and by opening and closing the valve you could adjust the amount suction from the drain.
