Fresh water must be added periodically to the plumbing. The chalk and other
chemicals will connect with the system and become solid. For avoiding this
closed expansion tank must be used in the system. In the systems that closed
expansion tanks are used, water will flow in closed system so it will not evaporate
and lost. So in this kind of systems the water level wiill stay same and fresh
water addition will not be necessary. This will prevent chalk and dust and the life
of the ssytem will be long.
PLUMBING INSTRUCTIONS
