Installation and electrical connection
▪ Ensure that the connection to the pressure pipe is stress-free – do not screw it in too
tightly.
▪ Seal pipe connections with Teflon tape.
▪ Install all specified valves in accordance with local requirements (gate valve, non-re-
turn valve).
▪ Install the pressure pipe so that it is protected from frost.
▪ Install the pressure pipe as a "pipe loop" to avoid backflow from the main public
sewer.
At its highest point, the bottom edge of the pipe loop must be above the locally de-
termined backflow level!
