The water I have coming into my home I feel we should have tested.I know the water has a high calcium content, at times I have chipped calcium residue off the inside of my commode take. We have had to replace the hot water heater, and 2 commodes because the calcium has clogged them. I had a 2 filter GE whole house water filters installed and within 30 days my filters turn from pure white to brown. I would like to know if you could recommend a place to have the water tested and approximate cost of doing so. Thank you for any information you can provide.
