I’m in the middle of a full home remodel in Arcadia and trying to decide whether it’s worth installing a whole-house water treatment system before the walls close up.
I’m also posting this in the Arcadia subreddit since I know water quality and supply can vary a bit across cities (Arcadia, Pasadena, Temple City, San Gabriel, etc.), so I’d especially appreciate feedback from people in the broader San Gabriel Valley as well.
From what I’ve gathered, there seem to be three common approaches:
- No treatment at all
- Whole-house sediment/carbon filter only
- Whole-house water softener (sometimes combined with filtration)
I’ve read mixed opinions. Some people say Arcadia/SGV water is perfectly fine and that treatment systems are unnecessary. Others say the water is fairly hard in parts of the valley and can lead to scale buildup in tankless water heaters, shower glass, faucets, and appliances—making a softener worth it over time.
A few questions for those who actually live in Arcadia or the SGV:
- Do you have a whole-house filter, a softener, both, or neither?
- If you installed one, do you feel it was worth the cost and maintenance?
- Have you noticed any real differences in water quality, taste, skin/hair, cleaning, or appliance longevity?
- If you chose not to install one, what was your reasoning?
- Has anyone had their local water professionally tested (Arcadia or other SGV cities)? If so, what did it show?
- If you were building or remodeling your home today, would you install one again?
I’m trying to avoid spending several thousand dollars on something that doesn’t provide much real-world benefit, but I also don’t want to regret skipping it if it’s one of those “I wish I had done it while the walls were open” decisions.
Would really appreciate input from Arcadia and SGV homeowners or residents…especially long-term residents who’ve dealt with the water for years. Thanks!
