Top Fill Line

Why a top fill line

A top fill line lets you fill the tank through the top, so there is no fitting through the sidewall. With hazardous chemicals, keeping the sides of the primary and containment tanks intact is always a good idea.

What’s included

• A ball valve to open and close the flow
• A ball check valve to keep liquid from flowing back out of the tank
• An optional anti-foam leg for liquids that foam when they splash

Top discharge line

The same idea works in reverse: a top discharge line draws liquid out through the top, again without a sidewall penetration in either tank.
