under the weather...

Felt a bit out of sorts today so laid particularly low.  Personal and systems maintenance the only task for the day.  Been noticing lately that my solar hot water doesn't heat up as fast as it should.  Turned things off and disconnected hoses - found that my thermosyphon was not syphoning.  The low valve out of the tank was clogged with sediment.  Only thing to do was remove the valve stem, poke a wire through, and let the water flow.  Got a brief blast as the valve cleared then buttoned up all the connections.  Now the water is back to circulating as it should - perhaps a hot shower tomorrow afternoon.  58,70,34,0,C
