Hi. Can someone explain in detail which direction the arrow should face. In our house we have taps/toilets with arrows facing towards the appliance and some the opposite direction. I thought it has to face the direction of flow. Is that correct? If do, does that mean if placing an isolation valve for a tap for instance, should it point to the tap?
Why is it important that it faces the correct way? What happens if placed incorrectly?
Ta in advance.
I like detailed answers, so don't be afraid to write lots
