Frequently Asked Questions

How does the one-touch lever work?

Squeeze the lever against the handle to open flow; release to close. It operates with one hand, keeping your other hand free for plant handling or support.

What does "full flow" mean for this valve?

The 5/8in ball opening matches or exceeds the inner diameter of most greenhouse hoses, so the valve does not restrict flow below the hose's rated capacity.

Is the insulated grip heat-resistant?

The grip is insulated primarily for comfort during extended watering sessions. It is not rated for high-temperature fluid applications.

Is this valve repairable if it fails?

Dramm valves are built for longevity. Contact Dramm or your dealer for parts availability if service is needed after extended use.
