Apartment buildings converted and sold as ‘condos’ do not have individual water meters - so the Home Owners Association fees have to include hot & cold water costs. They also raise revenue by keeping coin operated laundry rooms.
Putting one of these under the kitchen counter - near the sink works really well;)
I have one of those in my bug-out van — only tested it with water, no soap: it did seem to work — but it is there to use if needed. BTW only cost $100 at BigLots at the time.
