7.9.4.8 Grouping pumps
You can group pumps and use the same pumping algorithm separately on each group. If you
specify different pumping algorithms, then you do not need to use this parameter because
the pumps are already grouped by algorithm.
Group pumps only when four pumps are using the same algorithm, and you want to split
them into two groups.
Example:
Pumps 1 and 2 will operate as a group, and Pumps 3 and 4 will operate as another group.

7.9.4.9 Setting a flush valve
A flush valve stirs up the sediment at the bottom of the well during pumping, so that it doesn’t
accumulate. These parameters will control any relays set with Relay Function (2.8.1.4.)
(Page 195) = Flush Valve. Most sets of parameters will work with only one or two changes;
however, for these parameters to work, all of them must be set to a value.
Example:
The flush valve connects to Relay 4 and the watched pump is on Relay 1.
