A flat hose is literally flat and is typically known for being easier to store than most other hoses. Additionally, it is generally lighter than most, being easier to carry as it only inflates when water runs through it. Flat hoses come in many sizes and have myriad uses, but most offer easy storage and transport as the main advantage.
This type of hose must be completely extended before it will allow water to pass through it. Once it is unwound all the way, the water should have a clear path. Another typical characteristic of a flat hose is that the water usually needs to be drained completely before it can be properly stored.
One of the most well-known benefits of a flat hose is that it can easily be placed on the ground. It will not roll around, and it usually keeps in less water than regular garden hoses once the water is turned off because it is self-draining. Since it retains less water, it is also less likely to crack or freeze during storage. Despite the fact that it usually weighs about one third less than most garden hoses, a flat hose is typically capable of depositing the same amount of water as round hoses.
A common type of flat hose is made from vinyl like most regular garden hoses. It is usually much smaller than the typical hose, and is more durable. This kind of flat hose usually can be found at the local hardware store.
Another common type is made of polyurethane liner and is covered with a woven polyester exterior. This is usually the more expensive kind, as the hose liner is connected tightly to the exterior. This is an advantage that typically results in fewer kinks.
Some flat hoses come with a reel that makes storage easy. In fact, some reels are retractable. Hose owners can also buy a reel separately from a hardware store much like they would for a typical garden hose.
Other helpful tools are available for flat hoses, as well. For example, such a hose often fares particularly well with sprinkler heads since it can be placed on the lawn and left alone to slowly water the area. There are even flat hoses with three heads to which three sprinkler attachments can be connected for the ultimate coverage.
