Have calcium and chlorine deposits restricting water flow through PVC lines from pump to pool what will desolve it?

Hmmm, are you sure about this? If your lines are plugged with calcium I would hate to see what the pool looks like. What are the symptoms? What is the pressure reading on the filter tank when the pump is running? What is the filter pressure when the filter is clean? Wen was the last time the filter was professionally cleaned. Do you have a sand, D. E. or cartridge filter?
