I have a vocational qualification in plumbing! NVQ Level 2.
when beest and I first bought a house, we took plumbing classes at night school. It was fun. We replumbed and rewired the whole house (totally reconfigured the bathroom, separated off the toilet, put in a corner bath..... Fucking useless over here though, everything's weird
We moved in to our house here and tried to fix a dripping tap/faucet/whatever. Took it apart. WTF? Took the bit that looked dodgy into Home Despot, didn't realize we were talking a foreign language when we said we needed a new one of these for our bathroom tap.
