25 Gallon Portable Spot Sprayer

[dmad1]

After posting that for several years we have used a portable sprayer for transporting drinking, Gordon 2 brought up the safety of using a tank originally made for spraying pesticide and suggested I contact the maker of the unit and ask their opinion. Below is our conversations and the response from the Master Mfg.

This the email I received from them this morning...

"They are not certified for potable water. With that being said, many people do use them for this purpose. We just have not gone through the certification process."

Well, people smoke for longer than seven years before getting lung cancer. People are exposed to asbestos for more than seven years before coming down with mesothelioma. But perhaps the most likely concern is lead in the pump, since it is not for potable water use, they are free to have high lead content.

May I suggest that you at least contact the manufacturer at Master Manufacturing Support - Contact Us and ask if the sanitized tank, pump and and hose is safe for human water consumption. If they say yes, then this is a good idea for people to use to transport water to their campers.

Thanks for checking Dick.

Personally, I use the water in my trailer's domestic tank for showers and dishwashing, but never for drinking or cooking. I would not be concerned about "certification" for potable water.

I don't see that that reply answers any question of safety. "...many people do use them for this purpose. We just have not gone through the certification process." That may seem to imply that IF they were tested for certification they would pass. But the manufacturer didn't specifically claim that and without being tested who knows? As was noted above, smoking, lead, and asbestos in relatively small quantities may take years for negative results to show up. So "many people do use them for this purpose" means nothing.
I have, since childhood, and that was a long time ago, drunk water from un-certified hoses, both rubber and plastic, without known adverse effects, and I am now over 80. Not all the time, or even what might be considered regularly. The main reason not is because it tastes lousy. But on a hot summer day working outside you drink what is handy and RELATIVELY safe. Better from a hose than from a mud puddle. However, if I were a hose manufacturer I would not recommend the practice. Liability and all that. So the manufacturer didn't say it was safe. Just that they had not had the safety checked. Caveat emptor.

We are almost the exact opposite , we only use the water in the onboard tank for drinking , coffee, cooking , and occasionally flushing the toilet.

I’m more concerned about what I’m putting in my tank.
Enter your zip code and see what your water is like.

I see this as a perfect response as it was designed for insecticides and not potable water use. Certification for some unintended use would be redundant on their part. How an end user decides to use it is on the owner dime.
