You can and it would be very effective but I’m not a fan personally.
a) You will save around 40% in terms of water usage.
b) Your lawn will be easier to mow and will look great
a) It can be impossible to really know if its not working. You can install signal flags in the line, but you can only use so many of them before it looks odd.
b) Locating problems can be difficult and requires digging up your lawn to make repairs.
c) Its more expensive
So – yes – you can do it – but I wouldn’t want to be maintaining it!
