This Appraisal is for Hydraguard and Retraguard ant barrier devices for hydrant access wells.

Ants are able to completely fill a hydrant access well with soil in as little as 2-3 months. Despite ongoing high levels of maintenance and associated costs, the ants often win out, resulting in inaccessible and inoperable hydrants. This can result in unnecessary property damage and even potential loss of life.

Hydraguard and Retroguard provide a physical barrier between the hydrant and the bottom of the well thereby preventing ants from transporting soil upwards and filling the hydrant access well.

Hydraguard is available to suit DN 80 or DN 100 hydrants with either circular or square shapes.

Retroguard is a complementary product to Hydraguard that allows for a retrofit installation on existing circular flanged DN 80 hydrant assemblies.
