The One Stop Box from LSP Products Group - part of NCH Corp. - is a small combination valve, condensate and drain box designed mainly for new construction. It is also suitable for replacing an existing outlet box, as the valves are replaceable. This means in the future, if a plumber has to replace the valves, they can do it fast and easy without the expense and hassle of cutting into the drywall, disconnecting/cutting the water supply lines, removing the valves, putting in new valves, reconnecting the waterlines and repairing the drywall. All they do is remove two screws, pull out the metal bracket, pull the current valve out, put in a new valve, and reinstall the metal bracket and screws. No drywall or water supply line work is required. 800-854-3215; www.lspproducts.com.
