Non-toxic garden hose: which one to choose?
If you grow your own food, a non-toxic garden hose is a must have.
One of the reasons people are gardening is to be able to grow chemical free produce.
And it seems quite an achievable task: buy organic seeds, plant them in healthy soil, fertilize with organic fertilizer, do not use conventional herbicides and pesticides, and here you have your tasty toxic free organic crop.
Or do you?
Oftentimes, one step gets easily overlooked.
As gardeners, we need to water our plants. Without much thinking we are using hoses that are full of toxins for watering our garden. And by using them we contaminate plants that are meant to be eaten, and contaminate the soil in which the plants grow.

The truth about your garden hose
A lot of people think that when they buy a gardening hose from Lowe’s or Home Depot – it should be safe for watering plants. (Especially if it has writing on it “safe for drinking”). It can’t have toxic chemicals, the governmental agencies will not allow harmful toxins to come in contact with the food supply, right?
The answer is – wrong.
Walk into Home Depot, Lowe’s, Walmart, Target today and take a look at garden hoses.
Unfortunately, the “Proposition 65 State of California warning label on them – “this product contains a chemical known to the State of California to cause cancer and birth defects and other reproductive harm” – glares right in your eye with an unpleasant truth
Garden hose safety tips
- Keep your hoses in a shaded area, since heat of the sun increases leaching of toxins into water
- Before using hose let the water run for at least 10 seconds, because the water that has been sitting in the hose has the highest level of chemicals
- Always let water run until it cools off in summer time in order not to kill plants with hot water
- When you turn the water on (especially If you didn’t use hose for a while), point the hose away from the face in order not to inhale accidentally legionella bacteria that can grow inside a hose
Garden hose study
In June 2016 ecocenter.org conducted a garden hose study.
32 hoses were tested, including hoses marked as safe for drinking. 24 of the tested hoses were made of PVC.
The test results were quite gloomy.
PVC hoses were the worst offenders. 75% of them contained phthalates (plasticizers). Lead, as well as bromine (associated with flame retardant), tin, cadmium, antimony were found in PVC and metal fittings of the garden hoses, The tests showed presence of the recycled PVC from electronic waste. The worst thing is that BPA and lead were found to leach into water from PVC hoses.
The study concluded that hoses labeled as “drinking water safe” were safer but still contained phthalates. Yet lead, antimony, tin, bromine were low or undetectable in the flexible hose layer (excluding fittings).
The tested Parker synthetic rubber hose showed high amounts of chlorine and lead.
Hoses made of polyurethane were among the safest ones, though some of them still had chlorine or lead in fittings.
The best non-toxic garden hose
Only two hoses among tested ones – Big Boss AquaStream Ultra Light Garden Hose and Water Right Professional Coil Garden Hose (both were bought for the tests from Amazon) – did not contain toxic elements.
I was not able to find Big Boss AquaStream hose on Amazon today. I saw only Big Boss expandable garden hose that was discontinued by manufacturer and had some bad reviews due to lack of hose quality.
Yet the Water Right Professional Coil Garden Hose is available for the purchase and seems the only choice if you want a truly safe drinking water hose to insure non toxic supply of water for your soil and your edible plants. (Disclosure – I do not have affiliation with Water Right brand)
The reasons to get Water Right hose:
- 100 % lead free
- BPA free
- Made from UV stabilized FDA and NSF grade polyurethane
- You can choose stainless steel or chrome plated lead free brass fittings option
- can be used with hot water
- Made in the U.S.A.
- Test conducted in 2016 showed that it is a truly non-toxic hose
I personally have owned four Water Right hoses (not coiled version) for at least 8 years. I absolutely love them. The only problem I have – they are hard to coil on the hose reel due to their relative stiffness, however this also makes them more resistant to kinking when they are pulled around the yard.
What about stainless steel garden hoses?
Are metal garden hoses safe?
I got an inquiry from a reader. He was wondering if stainless steel hoses are non-toxic.
The reader rightfully pointed out that manufacturers usually do not tell you what steel garden hoses are lined with and asked if I can suggest a stainless steel garden hose with lead-safe linings, such as polyurethane.
When I took a look at stainless steel garden hoses offered on Amazon, a hose made by Touch Rich caught my attention.
Its description stated that the outer shell of the hose is made of 304 stainless steel (16 gauge,3/8” ID,5/9” OD), and the inner hose is lead, BPA, phthalates free, and drinking water safe.
This hose is made in China.
The thing that I am not sure of is the fittings on this hose: whether they are brass or aluminum. There are mixed answers about it. But the last person that got this hose in April 2020 wrote “The 50′ hose I received 3/20 does have heavy duty BRASS fittings.”
There is no testing or study that I can find on this hose. The manufacturer claims that this stainless steel hose is safe for drinking water, BPA free, lead free, phthalates free. Would you trust the manufacturer? It is up to you to decide.
Pin for later reference!
Final thoughts on non-toxic garden hoses
If you grow your own food – get a toxic free hose. Stay away from hoses made from PVC and synthetic rubber. Your best bet is to choose a drinking water safe garden hose made of FDA and NSF grade polyurethane and with lead free fittings, such as Water Right hose.
