Tap water in Puyallup has about 29 mg/L of hardness, which is 1.7 grains per gallon. On the USGS scale that counts as soft. The number comes from Tacoma Water Division City of, dated September 2025. Reports for this system disagree, with values from 18 to 29 mg/L.
Puyallup sits close to the typical Washington figure of 36 mg/L. Of the 10 nearest cities we track, 6 have softer water and 4 have harder. The range nearby runs from 22 mg/L in Summit to 95 in Lake Tapps.
What 29 mg/L means at home
Soap and shampoo lather with very little product. Kettles and showerheads stay mostly free of white crust.
Some people notice that soap feels slow to rinse off in soft water. That slippery feel is normal and harmless.
Hardness is not a health problem, and EPA sets no limit for it. It is a matter of scale and soap.
What to do about it
Nothing, as far as hardness goes. At 29 mg/L a softener would have almost nothing to remove.
Carbon filter
If the water tastes of chlorine, a pitcher or faucet carbon filter takes care of that. It does not change hardness.
