[rapanui 2]

This is what I found after buying my water maker from sea water Pro!!
How they decide to ignore this warning and endangered the life of customers!!!

Where do you see that SeaWater Pro uses the Chinese Spring Check Valves, to which you link?


For instance, SeaWater Pro utilises DOW FILMTEC SW30-2540, 40 inch Reserve Osmosis Membrane[s].

I talk about spring valves used for the feed of fresh water from the tank to flush the system threw the carbon filter you do not understand my post not talking about filmtec membranes!!!

You're right, I didn't understand your post.

While not great, the valve you are describing isn't going into your potable water supply, but instead is going overboard as a fresh water flush. It's also going through a carbon filter which will take the lead - the concern with this valve - out of the water. It's a risk I'd be willing to take.

The valve in question is a simple little spring assisted swing check valve made of PVC with a Stainless spring.
Where's the lead coming from that you are worried about causing cancer?

I doubt a lot of water makers are officially drinking water approved. But the only thing that would need to be is the product output. Any possible lead issue of those check valves would not make it through the membrane

Perhaps much of the problem indicated above is associated with regulatory gems like California Prop 65 (https://oehha.ca.gov/proposition-65/...proposition-65).

Prop 65 claims to offer citizens "information" to "make informed decisions about their exposures to these chemicals".

In fact, Prop 65 largely offers paralysis, since nearly any substance you eat or drink as well as the equipment used to prepare them, will contain known cancer-causing chemicals listed under Prop 65. Some of these chemicals are ubiquitous, and many are naturally-occurring. Pb is just one of over 900 listed.

Prop 65 bureaucrats finally did decide that individual coffee cups didn't need Prop 65 labels on them, even though coffee always contains chemicals listed under Prop 65. Hamburgers and steaks, too. In all likelihood, probably any item you eat or drink will contain some, depending on the ability of analytical equipment to quantify or detect it.

Anyone up for a "cold one" after a long day of sailing...bad idea "Alcoholic beverages are on the Proposition 65 list because they can cause cancer. Consuming alcoholic beverages increases the risk of cancers of the mouth, throat, voice box, esophagus, liver, breast, colon and rectum."

I wonder if the reluctance of water filter and purification system manufacturers to list their systems as providing drinking water stems partly from the legal peril they face under Prop 65 in making any such claim.

Carbon filters mostly filter out organic matter and chlorine. I’m not sure they do much for lead.
From another post, why would lead be leaching out from a PVC and SS component valve?

Okay, but that's not snitching.
Thanks for your concern, and checking out something that doesn't seem right.
That's what this forum is about.
I think in this case more appropriately would be danger from lead poisoning.

rapanui2 obviously does not write English as a first language. Cut him/her some slack.

I suspect the manufacturer is being ultra cautious.

As mentioned above - where is the lead?
Lead is certainly toxic but probably only slightly carcinogenic - if at all.
Compared with so many other toxins we encounter in day to day life I think this little plastic and stainless steel valve is hardly of concern.
Get real.

Distillation, reverse osmosis, and activated carbon filtres all remove lead, from drinking water. To be National Sanitation Foundation [NSF] certified, a filtre or filter media must remove 15 ppb of lead, down to at least 10 ppb.
