Sorry to hear of your problems.
I'd agree with you about the cheap fittings and the plumbing methods leave a lot to be desired. Having been through several hoses because of ends failing, offset wall-to-faucet adaptors because of splitting
(What is the point of them? To compensate for not being able to position two pipes correctly? And, how do you grip them to turn them? Not with any normal plumbers' tool. Then, trying to align them both and have tight fittings...grrrr. And, then, those flimsy covers (?) that, when threaded as close to the wall as possible, to provide some sort of protection, I assume, from splashes, not for any aesthetic reason surely, fall off the back of the thread because the adaptor is too far from the wall by now anyway)
and taps, due to some fracture in the seams, in the last two years, not to mention having to have two meters replaced and several associated fittings, we wonder why this is so prevalent, having lived 120 years between us, often in worse winters than they get here, with never a problem before.
Anyway, water I fear more than electricity. If you need anything done, let us know.
