Water heater treatment (point of service) treatment system
I just received the SJ Wave water total hardness test strips I ordered on Amazon this afternoon 09/26/2021. Our NuvoH2O water heater treatment system was installed and put into service on 09/20/2021. The city of Kennewick, Washington told me that the water hardness of the municipal water system varies with the sources used from ~11 gpg to ~14 gpg. So, after having the system treating the water going into the water heater for ~ 6 calendar days I took the following measurements:
1] Control: Walmart brand distilled water purchased at Walmart in Richland, Washington, two samples both of which were green indicating 0 GPG (0 ppm) of total hardness.
2] Treated water: Two samples of water collected after flowing into the NuvoH2O water treatment cartridge and then into the water heater and after flowing out of the kitchen faucet turned on for 60 seconds; both samples produced test strips that were a light shade of brown estimated by visual color change to indicate a level of total hardness of between 0 gpg (0 ppm) and 1.5 gpg (25 ppm).
3] Untreated cold water that had not been treated by the NuvoH2O water heater treatment cartridge. Both samples of cold water were collected at the kitchen faucet after the faucet had been flowing for 60 seconds. Both samples of untreated water produced test strips that were a red “rusty” color estimated by visual color change to indicate a level of total hardness of between 7 gpg (120 ppm) and 15 gpg (250 ppm), very close to the color change indicating 15 gpg (250 ppm).
These results indicate that the NuvoH2O water heater treatment (point of service treatment) system was reducing the total hardness.
