I am not a plumber.
When I close the hotwater outtake valve from the hot water cylinder, I had expected that hot water water would stop flowing from the hot taps/faucets. i.e I expected no water.
However, cold water flows instead from the hot tap. If I open the hot water line valve, then hot water again flows from the hot tap.
Does this indicate a problem somewhere or is that expected behaviour? If it is a problem - is it one that should be addressed or can it be safely ignored? This is a rental property where the landlord strongly desires to repair nothing.
I have recently installed a washing machine, never made the above test prior to installation so unsure of relevance.
