Next time I suggest I attempt plumbing by myself someone shoot me. I've been at it since 2pm and i've more problems than when I started.
I would cry but then there'd be even more water damage.
My policy on plumbing is:
a) Only if I've got all the proper tools and materials, including those for dealing with the likely cockups.
b) I can get access with a minimum of swearing and grazed knuckles, and definitely won't need the spanner that can phase through solid matter.
c) There's at least one proven isolation valve between me and certain doom.
d) It isn't likely to deteriorate into complicated woodwork or crack something expensive.
e) Don't start a job when the plumber's merchant / DIY sheds / etc are shut.
and
f) Never hesitate to defer to chivalrous menfolk when it's minging drains.
Careful application of these rules has prevented me from perpetrating acts of Plumbing on countless occasions. Much safer to stick to electricity. It doesn't leak all over the floor when you get it wrong (well, it can do, but only while the power's turned on).
