I want to pressure wash high rise well drained balcony from time to time. No tap on balcony unfortunately. So the option is to connect to the laundry. Are the sink tap connectors any good? I'm thinking there would be too much pressure. If not we could connect to the washing machine tap, but am wondering if we could fit a splitter year round so I have the option to connect a hose year round? Would a good quality splitter make sure the apartment doesn't flood lol? Standard washer taps installed for context. Thanks
