Lead-free? Or low lead? No lead? They all mean the same thing.
In 1986, the U.S. Congress revised the Safe Drinking Water Act (SDWA) to use "lead-free" pipes with a lead content of no more than 8% in public water supply systems or human drinking water facility pipes.
In 2011, the U.S. Congress passed the Reduction of Lead in Drinking Water Act (RLDWA), which revised the definition of lead-free to include maximum lead content on wetted surfaces of plumbing products such as pipes, fittings, plumbing fittings, and fixtures, reducing from 8% to a weighted average of 0.25%, establishing a statutory method for calculating lead content. The Act came into effect on January 4, 2014.
The U.S. Environmental Protection Agency (EPA) lists eight third-party certifiers accredited by the American National Standards Institute (ANSI) to provide potable water piping and fittings testing and low-lead plumbing requirements for potable water systems and manufacturers. Test and mark the product. For example: Low-Lead, Low Lead Content, NSF/ANSI/CAN 372 and other labels.
Currently, brass is the main material for drinking water pipes and fittings. Lead brass has self-lubricating properties, good machinability, and corrosion resistance, wear resistance and physical/mechanical properties, and can meet various shapes of parts and part processing requirements.
When leaded brass is made into drinking water pipes and fittings, lead will be released under the action of substances in the water, and drinking leaded water will endanger human health. Medical research shows that lead has great damage to the hematopoietic function and nervous system of the human body, especially children's kidneys and other organs.
The Solenoid valve is the key component to decide what kind of batteries can be used. The opening of Solenoid valve needs a larger moment current, and AA Alkaline battery just meets this requirement, plus reasonable price, long battery life and current market mainstream these facts, therefore, AA Alkaline battery was chosen as the power source of the Automatic Faucet and Automatic Flush Valve.
If consumers purchased cheap carbon-zinc batteries which are also workable; but with less capacitance than AA Alkaline batteries, battery on/off life cycles are less than AA Alkaline battery; relatively, the more frequency of battery changing.
The Lithium battery is also workable, it’s no problem to meet the requirement of a large moment current. It has a larger capacity than AA Alkaline batteries; but the price is 4-5 times that of AA Alkaline batteries, battery on/off life cycle is more than AA Alkaline battery and the less frequency of battery changing.
There is material marking on the appearance of the battery:
- Carbon-Zinc battery: HEAVY DUTY or no marking
- ALKALINE BATTERY
- LITHIUM BATTERY
Both Alkaline battery and Carbon-Zinc battery belong to Zinc and Manganese Dioxide reacted battery type. Both batteries have the same volume, appearance and voltage; but different electrolyte. Alkaline battery is with higher energy density and more electrolyte than Carbon-Zinc battery. When these two kinds of batteries are mixed in a battery holder, the Carbon-Zinc battery will be exhausted first, and turned out to be a resistor draining Alkaline batteries. Therefore, don’t mix different materials of batteries in an Automatic Faucet.
Installing a new Alkaline battery 1.5V with 4 pcs to make 6V voltage, could last for 400,000 on/off battery life cycles. If new and old batteries mixed, for example: new battery 1.5V x 2pcs and old battery 1.2V x 2 pcs, installing 4 pcs would be 5.4 voltage, probably used only 200,000 on/off battery life cycles or less.
Therefore, new and old batteries mixed is 200,000 on/off battery life cycles less than all 4 new batteries. Suggested using all 4 brand-new, the same brands, and the same Alkaline batteries are the best when change batteries.
Don’t mix different brands of batteries.
Different brands of batteries with different conditions of the material grade, used volume and production equipment…etc. at production time, the produced voltage or inner resistor would be different from each other.
The mixed brands of batteries because of different production conditions would provide unstable quality of electricity than the same brands of batteries.

How to improve my water quality
Here are some tips to help improve your
water quality:
1.
Test your water: Have your
water tested by a certified lab to identify any contaminants or issues. This will help you determine the best course
of action.
2.
Use a water filter: Install a
high-quality water filter, either at the point of entry (whole-house filter) or
point of use (on a specific faucet).
Look for filters certified to remove the specific contaminants in your
water.
3.
Prevent contamination: Ensure
your water supply is protected from potential sources of contamination, such as
runoff, septic systems, or nearby industrial activity.
4.
Consider water softening: If
you have hard water, a water softener can help remove minerals that can cause
scale buildup and affect water quality.
5.
Maintain plumbing: Regularly
inspect and maintain your plumbing system to prevent issues like lead or copper
leaching from old pipes.
6.
Consulting with a water
treatment professional can also help you determine the best solution for your
needs.
