The regulation which presumably were written by qualified people a lacking some common sense.
I have Solar heating with lots of hot water, yet I cannot buy a washing machine or dishwasher that can intake hot water and can only intake cold and use electric to heat it up .
In my house the plumbing is such a long way to the kitchen sink I must run a dish and a half of water before the hot comes through, what a waste of water .
Why cannot houses collect rain water to use for toilets etc.
Why do public toilets hang the doors so you must grab the handle and pull to get out which people that do not wash their hands have handled. Pull to get in Push to get out.
Who write these regs,
