In the winter time I would like to use my 1" lawn irrigation water
source to flood a skating rink located about 200 feet from the house.
If I ran a 1" hose out to the skating rink, but I had a smaller
diameter fitting in the middle of the run, would water volume be
reduced very much?
Here is a description of my system: I have a 1" pipe that connects
directly from my well to my lawn irrigation system. The pipe exits
the house into a tee. One side (1" diameter) goes up to a shutoff
valve, followed by some kind of pressure valve and then down into the
ground to the irrigation system. The other side of the tee goes down
about 6" to a standard garden hose valve. That valve is used in the
fall to blow out the irrigation system with an air compressor. I want
to use the garden hose outlet for flooding the rink. I understand
that if I used a long run of a 3/4" hose, then the water volume would
be limited. However, if I were to attach a 1" hose to the garden hose
valve using the appropriate fitting, would volume be affected much by
the smaller diameter valve? In electronics this would be like
inserting a resistor, which would definitely affect the current flow.
So the question is "how big is this resistor"? In case it matters, my
well pump is capable of pumping about 20 gallons per minute. I could
find out more specifications if necessary. By the way, in case you're
wondering, I plan on blowing out the system from inside the house each
time I use it (there are convenient air hose fittings in the pipe in
the utility room).
I am a little concerned about getting water into the irrigation system
even with the shutoff valve closed (such as if there were a tiny
trickle of leakage). Any words of advice regarding this?
Thanks in advance for your help,
