Re: Solenoid valves (was Cat 5 cable)

["Mal Lansell" <mlansell@xxxxxxxxxxxxxx>]

Thanks for that.  It hadn't crossed my mind to use ordinary hosepipe for
the
long runs - it would be much easier to route than the stiffer irrigation
pipe.

I used to have a single system driven from one of the hoselock water
computers, but I can't cover enough of the garden with that, and now the
plants have grown the sprayers are blocked with foliage!  I have to re-lay
it all, so multiple zones and drippers rather than sprayers are the plan
this time!
