Well, this is what it looks like, now:
Clicking the little boxes to the right shows
a slightly larger pic. The woodlot at the back,
the apple orchard in front of it, and another
to the right (off pic) are all benefiting from
more regular, automated watering. As are
madam's gardens. I've even managed 6 days
away without any problems occurring.
Before that, the new (circa 65psi) higher
system pressure caused three pipe ruptures.
So I programmed the the PMV electronic
timer to activate the solenoid-to-the-field
valve a minute before any irrigation cycle,
and shut off a minute after. Stock drinkers
in the areas soon drop the field pipe pressure
to zero, between watering cycles.
Had some problems with the pump control
board, necessitating an expensive visit by
an electrician. The copper paddle in the
no/lo flow switch had almost eroded away.
I fashioned a replacement from stainless
steel. Also had a siren fitted for when any
fault condition shuts down the pump.
I'm sure Wet Boots will be scratching his
head in even greater amazement, but the
bill from the electrician's firm contained so
many mistakes! Just received a credit for
about $NZ1200. The original bill was $2096!
Unsurprisingly, I've told the crowd that did
the field irrigation installation (as depicted
in the pic) not to darken my driveway again.
I was going to put the pic in the other thread
named:
Controller To Do Hybrid Switching
but the link says that thread has gone.
Wonder why?
Aside from showing the end desired result,
my other reason-for-posting is to again say
thanks to everyone who helped me resolve
all the problems I faced. It would have been
so much more difficult and time consuming
without that assistance. Especially from Wet
Boots, despite the somewhat acerbic tenor
of some of his observations, fair comment
and all, as they may've been, at the time.
If any forumite ever travels this way, send
me a PM or an
e-mail , in case we have the
option of a get-together of some sort.
Next problem: sealing the pond and getting
water feature installed.
Onward & upward!
