Garden Hoses: What To Know Before You Buy

Hose for gardening don't last forever. When you're in the market for a new one, these tips will help you make an informed purchase.

Your garden hose is probably working overtime this summer as you water plants, irrigate a vegetable garden or wash the car. According to hose manufacturer Teknor Apex, a good garden hose will last five to 10 years if properly maintained. A bad garden hose, as most of us have already found out, will waste water, function poorly and cause bouts of frustration.

So to keep the kinks out of your relationship with your PVC garden hose, let’s take a look at what to consider before you buy a new one. 

Materials

Mostly, garden hoses are made from multiple materials. Some garden hoses are even made from up to 8 different layers. All these layers are made from a different material. The outer layer has to be strong because it’ll be dragged along concrete and stones. Often PVC is used for this outer layer. The inner layer can be made from many different materials. If the expandable garden hose is suitable for drinking water purposes, often PU food-safe materials are used for the inner layer. All materials used together determine the temperature range, which is often between -20°C and +60°C. Garden hoses can often withstand pressures up to 30/50 bars (435/725 psi). A pressure gauge is placed to monitor the pressure in the system, to learn more about this read our article on pressure gauges for water applications. 

A garden products study completed by The Ecology Center looked at 90 different PVC garden water hose and discovered disturbing levels of each of those chemicals. Some of the toxin levels exceeded safe drinking water standards by 20 times or more.

We’ve all had to face some hard facts in recent years: it turns out there is no pristine environment anymore, and even those living in isolated wild places face contamination of the air, soil, and groundwater. But we can take steps to stop contributing to the problem in our own backyards with unsafe hoses. Rather than throw up our hands in despair, we can spread awareness about this lesser-known home health hazard. Not all hoses are created equal, and you can change your watering practices to help your hose do its job without spraying neurotoxins and endocrine disruptors. Because let’s face it: our bodies have enough to deal with in our modern environment without adding to their burden. 

Summer in America means kids laughing and leaping through the hose’s spray. Peaceful mornings in the garden, watching the tomatoes redden while we shower the squash and bean plants. Luckily, a bad hose doesn’t have to poison these pleasures; there are enough other reasons to lose sleep. Buy a new hose, made of natural rubber or polyurethane, and store it in the shade. As chemical hazards go, a toxic garden hose with fitting is an easy fix.
