What’s in Covina’s water?

Just to the north, Covina shares the eastern valley's hard water story, with supply pulled from the Main San Gabriel Basin and supplemented by imported deliveries during drier stretches. The dissolved calcium and magnesium in that groundwater are the reason so many local kitchens battle cloudy dishes and crusty faucet aerators. Chlorine disinfection adds a taste and odor that becomes obvious the moment you fill a glass straight from the sink. Water heaters in older Covina homes often wear out early thanks to the steady accumulation of scale inside the tank. PurAgain filtration removes up to 99% of contaminants, so families enjoy fresher water and appliances that hold up far longer.

The only way to know exactly what’s in your Covina water is to test it, and that in-home test is free.

Is the tap water in Covina hard?

Covina, in Los Angeles County, draws on local groundwater basins blended with imported supply, and it runs consistently hard.
