This set contains everything needed to monitor the pressure in the Bilbao sand filter: a pressure gauge showing the current operating pressure, a T-piece for connecting it into the tank lid, and a venting plug for releasing air pockets from the system.
The pressure gauge with a clear scale makes it easy to read when the filter is clogged and backwash is needed – normal operating pressure usually does not exceed 1.5 bar; when 2 bar and above is reached, backwash is necessary. The venting plug prevents the formation of air pockets that would reduce filtration efficiency.
All components are made for direct installation into the lid of the Bilbao filter tank via a rear thread; installation is easy and does not require bonding. The set is intended as a spare part for existing installations as well as for upgrading the filter with precise pressure measurement.
