Recently purchased 2004 Newmar Kountry Star and the water lines are full of Calcium rocks and are plugging up all the end uses, faucets, toilet, etc. Take off screens on faucets and shower head, turn water on and Calcium deposits blow out the hose. Put it all back together and soon it is plugged again. Don't know where all this calcium resides. Would LCR introduced into system be safe? Any suggestions would be appreciated.
