Well I finished my irrigation drainage system yesterday and it got an
unintentional stress test. I'd re-assembled the water timer and
manifold and forgotten to include the pressure regulator which meant
that there was a LOT more water going through the irrigation system
than normal.

Fortunately the new drain system worked flawlessly and is not flooding
my next door neighbours driveway anymore. You can't even see where the
work has been done as a frame and net supports three slabs and
surrounding gravel over the drains.

Just goes to show.. when installing an irrigation system ALWAYS make
sure your soil is either free draining or if not (like my thick clay)
to work out the lowest point and then run some sort of drainaway system
to your main drains.


If that much water is being collected that it needs draining away sounds
like you a e wasting a lot of water
