Multiguard is an ant barrier device for spring hydrant wells. It is well known that ants deposit soil in the bottom of a hydrant well, building their nests vertically until the cavity is filled. A newly installed hydrant access well can be filled with soil in as little as 2 to 3 months.
Multiguard provides a physical barrier between the hydrant and the bottom of the well, preventing ants from transporting soil upwards. It's built for existing 80mm/100mm underground hydrants already installed in large numbers by water authorities, fitting inside a Sn1/Pn4 225mm PVC thin-wall pipe and pushing on over the top of the spring hydrant. No main shutdown required, and no digging.
