don’t normally post during the day

…but I’m feeling a little frustrated, and vaguely hoping the weblogging universe has the knowledge I need.

I’m working at home, and C has a nasty cold – probably tending towards brochitis, as his colds often do – he went to take a bath, in the bathroom we don’t normally use for bathing. didn’t get enough hot water to fill the tub, which is sort of odd, since our shower in the other bathroom does just fine – sometimes/often even enough for 2 showers in a row.

I really don’t want to have to call a plumber, and I’ve no objection to doing things myself, but I’m not even sure where to start in this instance. (I have this sinking feeling it will involve crawling under the house, though.)
