The intake pipe must be slightly angled up towards the intake mouth to
avoid the formation of air locks.
Make sure that the intake pipe is completely airtight and immersed in the
water by at least half a meter to avoid the formation of vortexes. Always
fit a foot valve at the end of the intake pipe. It is advisable to fit a non-return
valve between the delivery mouth and flow rate adjustment gate valve to
avoid dangerous water hammering in the event of the pump suddenly
stopping. This measure is compulsory if the delivery water column is
over 20 meters.
The pipes must always be fitted using the related brackets to avoid
transmitting stress to the pump body. Take care not to damage any part
by overtightening the pipes when fitting them.
