I am replacing an ancient water softener which was removed from the pipes 15
years ago.

The house has two water heaters. Apparently there are also some soft water
zones (showers) and hard water zones (kitchen and bar faucets). There are
hot/cold and hard/soft water pipes going in all directions. The pipes are in
the walls.

After I have installed a new softener, how can I determine which faucets
have soft and which ones have hard water?

Thanks


One way is to add a very small amount of soap, in equal amounts, to a
given volume of sample. The soft water will suds up, the hard much
less. Also, the softer water will feel more slippery than the hard
water. Take samples to a lab and get quantitative results.
