Andrew, if we owned a place then we would check it top to bottom, and rectify any problems like leaks. But why should we, as tenants, take on the cost of pulling out panels and lifting floorboards, just to check the workmanship of past tenants and contractors. Surely, for all the crap we have to put up with from wanky letting agents (did you see I wrote they've taken 6 weeks to fix a shower?), I have the right to leave them with the hard work (and costs) of fixing the flaws in the place. Also, it wasn't my dumbass idea to locate a boiler at the furthest end of the house from the kitchen and bathroom, thereby requiring a ridiculous length of pipework between the two.
I don't like wasting water, and not just from a monetary viewpoint but also an environmental one, hence trying to reuse the run off in the water butt. But I fail to see how I could have reasonably been expected to take steps to avoid this leak and any others that may be ongoing. My point was that, with the hindsight of knowing this leak has been dripping away for years, and that there may be others, I'm glad not to have a meter in this house. I was really trying to address an earlier posters question about why anyone might be worse off with a meter.
Apologies for my tone, but as you can guess, you've hit a raw nerve. (6 weeks without a shower, and now the fuckers think I'm going to let them get away with leaving exposed wiring 6 inches off the ground in a house with 2 small children.)
