I have an watersoftener for the entire house, however the outside hose is not part of that system... Has anyone gone thru the effort of trying to connect into home system ?
i lucked out...
when we bought out house, it had a cold and hot feed for a washer in the garage, with a master cut-off in between. the washer is in the house, so i'm unsure of why the extra hookup is outside. anyway, early on, i installed a new water heater, and then got a softener installed for the house- Autotrol manual head, big ass Structural media tank, brine tank, etc. the unused garage washer outs, both hot and cold, are tied into the house softening. other spigots, irrigation, etc obviously are not.
my setup is the following in the garage for my car washing pleasure-
i use washing machine colored hose connections, one red and one cold with rotary shut-offs on the end of each hose. i then run the hoses into a y, and the y into my hose reel. so, not only is the water softened, but i can modulate the temperate with the rotary shut-offs. usually i have the cold side half shut off, and the hot side wide open, so the water i use is almost hot, but not full hot.
makes a big difference on many fronts!
the only bummer is the way the pipes are setup against the wall, they come out from behind the wall and are exposed for about 2 feet while running up to the mounted shut-off, so it leaves the possibility of them freezing in the deep winter. i had one of those thermostatically controlled pipe warmer things wrapped around them both and it's worked perfectly, allowing me to wash my car well in the winter and get that salt off frequently!
if you put the effort into tying the softener into a garage water supply, go the extra mile and get a hot feed out there.
