Are Garden hoses safe?

A very simple question, I plan to use my backyard spigot to fill my 220 as well as to fill its auto top off container, is there any reason I cannot use just a regular backyard hose for this?

Most are labeled as not being drinking water safe. I just needed a short one and Wally World had RV drinking water hoses cheaper than the regular garden hose. When I replace a garden hose the water that has been in the hose comes out with a strong chemical smell. It eventually goes away though.

I've used garden hoses before, and if you let the water run for a few min first, it will be ok. That said I much prefer either a drinking water hose or a hose made from clear PVC tubing.

Water sitting in a rubber or vinyl hose is the issue as chemicals leach into it. My RO unit and holding tank are located in a detached garage. Lowe's sells hose in 50' lengths listed for drinking water/kid water toy play safe and that's what I installed over a year ago. Not the greatest as far as kink resistance goes but no odor or taste change when water sits in it. (cheaper then RV hose too)

ive never had a problem and thats only way i fill it. here is some info and u can make your mind up. Proposition 65 is The Safe Drinking Water and Toxic Enforcement Act of 1986 which was passed as a voter initiative by the people of California. Gilmour labels its products, when applicable, to remain in compliance with California's Proposition 65 Act. For more information about Proposition 65 from The State of California Office of Environmental Health Hazard Assessment, visit

Proposition 65 does not focus on known risk factors for human cancer or reproductive toxicity. It only relies on lists of chemicals—information on many of whose negative health effects is based on high-dose animal tests and is not directly relevant to typical human exposures.
Proposition 65 is essentially a "right-to-know" law that seeks to provide consumers with information.
For more information about Proposition 65 from The American Council on Science and Health, visit

Gilmour prints a warning on product packaging simply to identify that one or more chemicals or elements from the California list is present in our products or used in the production of our products.

GILMOUR has awsome hoses if u have to replace yours and they back thier stuff up. imo i would be more conserned about water quality. this just seems like the nalgene bottle thing where it can leach when its hot, so just roll ur hose up so it has no water and if your realy concerned then let it run for a min to flush out.

Hoses contain anti-mold chemicals and all sorts of other goodies that go into making a stretch of rubber to last 20+ years.

I always fill my tanks with a garden hose and use one as a siphon. Just let the water sit without fish for a while to let the chemicals disperse/dissipate/evaporate.
