5.8 Provision for emergency drainage

On the rear, at the base of the station, is a connection for an emergency drainage system, marked by the

symbol

. You can use the connection to attach a secondary pump (for example a manual diaphragm

pump), the discharge pipe of which must be independent from that of the internal electropump in the station.

Identify the seat for the duct on the bottom of the station, open the duct and connect the emergency drainage

pipe. Check that the coupling is watertight.

Install a non-return valve in the pipe connecting to the public/private sewer network. This will avoid the reflux

of liquid. Place the valve at a distance of at least 1 metre from the lifting station to allow the flow of liquid,

moved by the pump, to open the shutter of the valve (unless indicated otherwise by the manufacturer).

Always refer to the local and/or national regulations, laws and standards in force.

The non-return valves are available as accessory kits.

5.10

Install an interception valve in both the inlet pipe and the delivery pipe (connection to the public/private sewer

network). In this way maintenance work can be carried out without having to drain the whole system. Gate

valves or ball valves may be used.

The interception valves are available as accessory kits.

See example of installation in chapter 4.
