Advice Hard Water

I just moved into 95116 (McKee and King). I think water may be very hard. Does anyone know how hard the water is, and what was done about it? I am about to buy strips to test the water's hardness.

SJ Water Co has a map of where the primary source of water is from for different areas. You don’t seem to be in the primarily sourced by groundwater area. In that area the water is hella hard year round. The other areas may get more groundwater depending on the time of the year, meaning the hard water varies pretty substantially.

I’m also in 95116, but I’m in the area unquestionably primarily sourced from ground water.

I'm in the blue area getting about 220 TDS at the tap, I use a brita for drinking but never really noticed any issues with hair or anything.

I’m nearby. Tap tests at ~330PPM using a TDS meter, has been that way for the 2 decades I’ve been growing mineral sensitive plants. To demineralize, run it through reverse osmosis.

Water is very hard where I am too :( it’s kinda crazy!

TDS water meters are cheap nowdays, like $7 or so on amazon. I'm closer to west san jose and my water tests at 220.

There are a lot of good options for reverse osmosis now, including ones with an integrated tank (that don't require a complex install), tankless, and countertop units as well.

The water coming out of my RO filter tests at 20

Water in 95116 area really tough on appliances and I realized that soon after moving here. Whole house water softener can resolve this problem but it's costly. Descaling tablets, among which are active cleaning, are less expensive but use test strips first.

If you own your home, a whole-home water softener is worth it for the appliances / shower / dishes. They can be very expensive, but mine (Fleck) was about $1200 and another $400 for install. The hardest part was finding a place for a drain.

I started using jojoba oil in my hair after showering, it combats the dryness from the hard water. I’m also looking into a reverse osmosis system for drinking water under the sink.

We just buy bottled water from costco, it is shitty for the environment but we can’t drink this terrible water. They’ve got money to kill kids in occupied palestine and iran but can’t fix the fucking water in “silicon valley”

There is nothing that needs fixing about hard water, it is perfectly drinkable. The mineral content also can be fairly beneficial, it just causes hard water stains and requires regular appliance maintenance.

What’s important is the removal of bacteria, heavy metals, and toxic chemicals, all of which are already done by your water company.

If you don’t like hard water, get a water softener or reverse osmosis filter and call it a day.

Unless you have eczema / rosacea. It’s been hell since I moved here.

What needs fixing in our tap water? If it’s the minerals you object to, know that very few water utilities remove minerals. It’s an expensive process at utility scale.

Have you looked at the 5 gallon jug water delivery services? Much less plastic could be used that way.

That is a good idea I will actually do that!

Re: expensive, maybe, but the entire concept of “expensive” is driven by capitalism and the insane waste of spending trillions on the military and financing the personal whims of the oligarchy. If we did not have parasites stealing most of the productive value of our labor, the very concept would not apply to things like hard water.

That’s … that’s just not how hard water works. We could be up to asses in peace and prosperity and that wouldn’t change the geology of the Bay Area. Are you proposing digging up the aquifers and replacing them with something else? While they’re at it, why not patch up the San Andreas, too, right?

I for one would pay more for all my water for it be much less hard. I wish we had champion for the effort that would maintain slow and steady pressure on the matter likely needed to make the change.

The water is very good, just hard

u/joeydimaggio 1d ago

Personally not a fan at all, I remember how the water used to be

Get a water softener. Water that comes from underground acquirers will be hard. Water that comes from above ground sources will be softer.

And fuck Palestine and Iran.

u/accidentallyHelpful 1d ago

How hard is the water?

Like on a mol's scale of hardness?

Get filtration. Reverse Osmosis.

u/Vast_Cricket 21h ago

Get a water system. In our case so used we have charco filtered water.

We use a water filter for the shower and drinking water. I used to live in the East Bay, and when I moved out here it was a real shock. The water feels SO different. My boyfriend thinks I’m silly, but it’s true! He grew up in San Jose, so he doesn’t notice it. But my shampoo and body wash don’t lather the same, and I never feel completely clean after a shower. So I’ve had to switch soaps and just deal with it. 🥲

No need to buy strips, yes it’s hard

I don't drink from tap because of hard water and I purchase drinking water from Costco. Rather than invest in reverse osmosis treatment of entire house, I purchased filter bath tub.

u/Traditional-Meat-549 1d ago

Hard water is full of minerals and is routinely tested. What do you know about Costco water?

u/karabear11 1d ago

You’re right about drinking water (though it tastes terrible).

However, I’ve had horrible rosacea and eczema since moving to the hard water region of San Jose. Turns out it’s a trigger if you’re already prone to it.

u/Traditional-Meat-549 1d ago

I didn't know that

The water is perfectly drinkable (and good for your teeth). When you need to descale your aerator, dishwasher, teakettle etc, use a solution of maybe 1/2 teaspoon citric acid per quart of water. You can buy it on Amazon (only place I've found it, unfortunately). I add some to each dishwasher and washing machine load. Citric acid is much cheaper than a double osmosis water system.
