How California's Water Saving Rules Change Your Shower
In California, saving water is part of everyday life. Shorter showers, low-flow shower heads and local drought rules all help the state make its water go further.
They also change how your shower feels. Here's what the rules say, why a low-flow shower feels different, and some simple ways to make every drop count.
What California's Water Rules Say
Shower heads are measured by how much water they let through each minute. This is called the flow rate.
Since 2018, shower heads sold in California can let through no more than 1.8 gallons per minute. In most other states, the limit is 2.5 gallons. If your shower has two heads on the same control, they have to share that 1.8 gallon limit.
In 2025, a new California rule took effect. It's called Making Conservation a California Way of Life, and it sets water saving targets for water companies, not for individual homes. Your water company decides how to meet those targets. So it's worth checking what they ask of you, especially during a drought.
Why a Low-Flow Shower Feels Different
Less water each minute can change your shower in a few ways:
-
Less coverage. The spray can be narrower, so the edges feel lighter.
-
Longer rinsing. Thick or long hair can take longer to rinse, especially with conditioner.
-
Cooler spray. Smaller drops lose heat faster, so the water can feel a bit cooler than you expect.
-
Shorter showers. Many people spend less time under the water, so each minute matters more.
Over time, buildup on the tiny holes in your shower head can make the spray feel even weaker. That's often the first thing to check.
Easy Ways to Enjoy a Low-Flow Shower
-
Clean your shower head. Soak the front in white vinegar for an hour. Then gently rub the holes to clear any buildup.
-
Rinse your hair in sections. This helps the water reach your roots.
-
Use warm water, not hot. Warm water is kinder to your skin. You also won't want to stay in longer just to warm up.
-
Catch the warm-up water. Put a bucket in the shower while the water heats up. Use it to water your plants.
-
Pick a shower head made for low flow. If you're buying a new one, look for one that meets California's limit and has a spray designed for low flow.
How a Shower Filter Can Help
When you're using less water, the quality of each drop matters more. A shower filter reduces chlorine, one of the most common irritants in everyday tap water. It also catches sediment (tiny bits of grit and rust) before it reaches your skin and hair.
Most California tap water is cleaned with chlorine or chloramine, which is chlorine mixed with a small amount of ammonia. The Daily Revitalize (SF100) is designed to reduce chlorine and low levels of chloramine.
Aquabliss filters fit between your shower arm (the pipe that comes out of the wall) and your shower head. Your shower head still controls how much water comes through. The filters are designed for high output, so they don't reduce your water pressure.
They take under 2 minutes to put in. You don't need any tools. They fit any standard ½ inch shower arm.

Frequently asked questions
Why does my shower feel weaker in California?
Shower heads sold in California can let through no more than 1.8 gallons of water per minute. That's less than in most other states. Buildup on the shower head can also weaken the spray over time, so a regular clean helps.
Does a shower filter change how much water my shower uses?
No. The filter sits before your shower head. Your shower head still lets through the same amount of water as before.
Do California's rules limit how much water my home can use?
The state rule sets targets for water companies, not for individual homes. Your water company may have its own rules, especially during a drought. It's worth checking with them.
How often should I change my cartridge?
The cartridge is the part inside your filter that does the work. Change it every 3 to 6 months, depending on your water. A calendar reminder is the easiest way to keep track.
