Above Ground Water Quality Safety Stations
The Hydro-Guard Blow-Off Sampling Station (B.
O.S.S.) provides a reliable and user-friendly method for taking water quality samples from a utility's own water distribution line. Using a permanent, dedicated sampling point allows utility personnel to access sample locations at their convenience—no appointment necessary. Hydro-Guard Sampling Stations are for use in warm or cold climates, with a variety of freeze protection options available for the protection of these devices in even the coldest of climates.
