Rust, sand or similar pollution int he medium, especially when rinsing
the system before the first setup, can cause buildup around the valve
seat. This can cause leakage of the valve seat.
When the prepressed packing is stored for a longer time, its sealing
ability can deteriorate. If necessary, the seal must be retightened at the
time of setup. The procedure is described in chapter "Maintenance
