Sure – this is Hunter propaganda, but in my experience MPs have proven themselves to be top quality nozzles over time. It is not uncommon for me to return to a house I installed MP rotators in after 3-4 years and see them performing as well as the day we installed them.
Yeah… that’s one of those questions that you can’t answer quite so easily…
The things to consider are:
- what is your water flow rate?
- what type of nozzle are you using?
- what type of sprinkler?
In most suburbs I work on around 30l/min flow rate but in places like Yanchep it can be as low as 18l/m or The Green in Butler it is around 22L/M.
From there you work out how many regular pop-ups you can fit on a line. For example a 12ft Toro pop-up nozzle with a 180 degree spray uses 4l/m, a 90 degree spray 2l/m and a whole spray 8l/m. However a 15 ft nozzle with increase water usage and a 10ft will decrease.
Then if you use MP Rotators you decrease water usage again but increase your spray distance…
So if you want to get it right then talk to someone who understands these variables or get a specification chart that can guide you in your planning. I have been to plenty of homes where the sprinklers are functioning poorly because the wrong kinds of sprinklers have been used.
