Vak Pak, Inc. is the originator of the fiberglass Main Drain. They produce more varieties of fiberglass Main Drains than any other manufacturer in the world.

All of our main drains are sized for gravity flow at 1.5 ft/sec through the grate and 3 ft/sec through the pipe connected to the collector tank.

Main Drains are available in 9” 12” and 18” sizes as well as custom sizes 24” and larger.

A rounded design on all our Round main drains (excluding the 24”) means you only have to square the grate to the pool walls, not the sump.

Slip by Slip or Slip by Thread couplings can be manufactured for ease of plumbing and pressure testing. (please specify SxS or SxT at time of order)

A 2” female adapter is provided in the bottom for a hydrostatic relief valve.

Each main drain has a sand grit finish to better mechanically bond to the concrete or gunite coating.
