2.9.4. Adjustable jet options
Adjustable spear jets are available (to order) for the PowerSpout
PLT. However, adjustable jets may cause more problems than
they solve and demand for them is generally low.
Adjustable spear valves as shown can be supplied for a surcharge
and operate in the range 3-14mm (circular jet equivalent).
They allow you to quickly adjust the flow rate to suit the stream
flow. However, there are some disadvantages of adjustable spear
valves:
They are more easily blocked by debris in the flow.
The efficiency of the jet (and hence output Watts) is a little
less.
