About this file
These are design and technical specification drawings for replacing water softeners at the St. Cloud VA Hospital, dated January 28, 2025. The project involves comprehensive replacement of three existing water softener units, including removal of old equipment, installation of new tanks, and modifications to piping, control valves, and associated infrastructure. Key technical requirements include installing new softener tanks in the same locations as removed units, using durable materials that can withstand salt and moisture, modifying piping to accommodate new connections, installing new drain line flow controls, providing new gages and sample piping, and ensuring proper insulation of inlet and outlet piping. The drawings provide detailed photographic and schematic documentation of existing conditions, control valve configurations, and specific replacement components and procedures.
The project specifications outline precise technical requirements for the contractor, such as providing new drain line pipes with isolation ball valves, fabricating galvanized pipe supports, installing dielectric fittings, replacing isolation valves, and implementing new control units with 120-volt connections. The replacement work is designed to minimize service disruption, with the specification noting that water softeners should remain in service supplying water to the VA hospital at all times, except during specific valve replacement periods not exceeding four hours. The contractor will be responsible for temporary piping and unit programming to accommodate the replacement process.

VHASTCPfeniM Text Box Plan Notes
1. Remove and dispose of the three water softener units. Include the tanks, bases, resin, drain line, flexible connectors, control valve and all appurtenances.
2. Install new softener tanks in the same locations as removed tanks. Level tanks as necessary per the manufacturers instructions. Leveling material, if necessary, must be of a durable material able to withstand salt and moisture with out degrading.
3. Modify piping to connect and accommodate contractor provided braided stainless steel flexible connections, control valve and existing CPVC brine piping. Install new CPVC isolation valve on the brine line for each softener.
4. Furnish and install new type L copper drain line. Provide new drain flow control as necessary. Provide new ball valves for drain line isolation of each softener. Fabricate and install a floor mounted galvanized uni-strut pipe support for the vertical section of drain line. Install additional hangers per code requirements.
5. Install new gages and gage/sample piping. Piping detail of this assembly is to be same as the existing. See plan photo PS-4. Fabricate and install a galvanized uni-strut pipe support for the vertical section of the gage sample pipes.
6. Insulate inlet and outlet piping, including flexible connectors, up to the softener control valve. New insulation is to be equal to the existing insulation. Modify hangers as necessary to accommodate insulation.
