The valve controlling the heating upstairs started dripping on the other valve heating downstairs causing it to trip, with nothing working.
On the same morning the toilet got blocked and threatened to overflow.
My lovely wife of course expected me to become a drainage and plumbing expert all at the one time, and the thought of fixing both, well, I went on to work.
Did f**k all about it for the next day. Looked at the situation 24 hours later, the drip stopped, the heating was working fine and the toilet cleared.
It shouldn't have worked but it did.
Maybe the plumber came round with his big spanner when you were at work.
I don't normally do this, but I let out a big laugh in the office and now everyone is watching me...
