I've been having my sprinkler system lines drained every fall. Unfortunately
I just had my lines drained last week and I forgot to mark where the heads
are placed within the lawn and I have a company coming out tomorrow to
aerate my lawn.
The only way that I can tell where the heads are is to run water back into
the lines and run the system. Ugh.
I'd rather not spend another $150.00 to get my lines blown dry and was
wondering if leaving water in them over the winter would completely destroy
them. My guess is that it more than likely would because of the water
freezing/thawing/heaving within the lines.
Any suggestions would be greatly appreciated.
The reason for blowing them out is to prevent the water from freezing,
which will crack heads, valves and possibly pipe too. BTW, $150 to
blow out a home system sounds high. Here in NJ I had it done for $50,
but then realized I can do it myself with a decent air compressor.
That's what I've been doing for about 7 years now. Takes about an
hour and I'm done.
