Greetings,(posted 8419 days ago)One solution for those having water problems, at least in the U.S, is to purchase a filter. These are available in most large home stores i.e. Home Depot. A whole house filter, with replaceable cartridges sell for $20-30 and can be fitted with a 5 micron filter. With the 5 micron filter, they work very well for processing film. I would not recommend using one for the entire house, as filter life would diminish quickly, but it will last quite a while filtering water for the darkroom.
