The ground doesn't freeze here in SE Virginia. It only dropped into the
teens once or twice this year.

I received a reply from someone in the Lawn & Garden group that has to do
with the way my irrigation controller is set up. I may have two lines
coming from my pump. One that is "always on" and triggered by pressure and
one that only comes on when my controller tells it to.

Last fall I extended my irrigation system by tapping into the main supply
line and creating a manifold with three solonoid valves and one "direct"
line with a manual valve.
I ran an additional line to the rear of my property for an "always on"
hose
spigot. I didn't hook it up over the winter. Each of the irrigation valves
work well.

Now that we won't be getting any more deep freezes, I hooked up my "always
on" valve to the line running to the spigots.

To my surprise and puzzlement the pump will not supply water to this line
unless one of the irrigation valves in the manifold are open. I don't
understand this. The valves are "downstream" of the direct line and should
not have any affect on the valve that is tapped directly into the main
supply line.

It seems to me that when the manual valve is open water should flow out of
the valve to the spigot. Tests have shown that water will flow freely to
the spigot when hooked to a garden hose.

I am puzzled why the pump won't come on when the manual valve alone is
open
and only when one of the irrigation valves in the same manifold is
operational.
Any thoughts would be greatly appreciated.
