The Amazon adaptor arrived yesterday, so I thought I=E2=80=99d update =
this with some new information. The adaptor was well made and the =
shut-off valve proved to be very handy; it was well worth the $20. It =
also came with excellent instructions that mostly agreed with what was =
said here, with one exception: it said =E2=80=9Cavoid blowing compressed =
air through the PVB because doing so may damage the BVP.=E2=80=9D I =
assume my system has a BVP in it, but can=E2=80=99t find it and just =
went ahead and blew it out from the basement as discussed.
The instructions also recommend that the compressor should be "as large =
as possible, preferably 15 gallons or larger.=E2=80=9D I think that is =
good advice, as my little HF 8 gallon compressor was barely (I think) up =
to the task. I initially set it to 50 lbs, the recommended pressure, =
but it was only putting out about 40 lbs during use, so I turned that up =
to get it a little higher. Even so, the compressor would fully extend =
the spray heads for the first 15 seconds or so, then just bubble water =
out with the head retracted. The compressor ran constantly while the =
system was on, so I gave it a rest between blowing out each zone. I =
also blew out each zone at least three times, but there was sill some =
spray at the beginning each time. I am going to do it one more time =
today, but know it won=E2=80=99t be completely dry. I assume it won=E2=80=
=99t be an issue when the little bit of water remaining in the system =
freezes, but someone please let me know if I am wrong about this. My 60 =
gal compressor is about 150 yards away from the water inlet, but I could =
make that work if necessary.
Just in time, as the cold weather arrived today, with the first below =
freezing temps expected tonight.
Cheers,
Jim
