Keeping an irrigation system working right year-round in Memphis is not about buying more hardware-store sprinklers. The number one mistake we see is homeowners trying to DIY the whole system. Hiring a professional for install, winterizing, and spring pressurizing is cheap insurance compared with cracked hose bibs, flooded interiors, contaminated drinking water, and yards that never water evenly.
This post covers what fails on DIY hose-spigot setups, when you should call a pro, why backflow matters, and how a custom Green Earth system is built so maintenance stays simpler.
The #1 mistake: DIY systems that look fine until they do not
Homeowners often run hoses from hose spigots and call it irrigation. It can look like it works. Then winter hits and the system was never winterized. Water left in the line freezes, expands, and can crack the hose bib. Last year a DIY system failed that way: freezing water, a cracked hose bib, flooding inside the house in 20°F weather, an emergency call, and the house water shut off for repair.
That is an expensive way to learn that hose-spigot setups are not a full irrigation system. If you are not familiar with how irrigation works, hire a professional for the install, for winterizing, and for pressurizing in the spring. It is more than turning water on.
Why hardware-store sprinklers struggle with coverage
Uniform precipitation rate is critical. It is hard to get with typical hardware-store lawn sprinklers. Some areas get too much water. Others get not enough.
DIY coverage problems we see again and again:
- Uneven precipitation rates across the yard
- Zone duration that was never dialed in
- Hose valves with no proper watering schedule
- Limited programming and no real calendar schedule, so systems often run once a day with no thoughtful timing
Dialing that in without specific zone run times is tough. A designed system with correct heads and zones is built so watering matches the plant material and the soil, not whatever the hose layout happens to spray.
Common DIY fails (and the one that puts drinking water at risk)
Wrong heads, no backflow, and bad wiring all show up on DIY jobs. Spotlight the backflow issue: no backflow preventer is dangerous for drinking water. That is a main reason to do the system right the first time.
Without a preventer, you risk contaminating drinking water inside the house. Running water indoors can create a siphon that pulls dirty outdoor water into the house supply. Hose-spigot DIY is only acceptable if there is a backflow. That is rare on DIY installs. Systems tied into the water supply generally need a certified plumber, so most DIY hose setups never get a proper backflow at all.
If something is already leaking, shorting out, or watering unevenly, sprinkler repair is usually smarter than another round of hardware-store parts.
What a professional system does differently
Green Earth builds every system custom to the property. Head count and zone count are never the same from one yard to the next. The design is intentional so winterizing, programming, and seasonal start-up are easier, not harder.
A proper irrigation system is planned for coverage, backflow protection, and maintenance access. That is different from a hose run that “kind of” waters the lawn.
Spring irrigation pressurizing is another place DIY falls short. Homeowners open the system themselves and overlook critical parts such as safe backflow operation and efficient water use. The same cheap-insurance logic that applies to winterizing applies when you bring the system back online.
Winterizing as cheap insurance
Paying to winterize properly can save thousands when a freeze would have wrecked a DIY line or hose bib. About $125 to do it right is cheap insurance. Skipping it is how you end up with cracked fixtures, indoor flooding, and emergency shutoffs in 20°F weather.
If your yard still depends on hose bibs and store-bought heads, treat winterizing and spring pressurizing as non-negotiable professional visits, not optional weekend chores.

FAQ
Is a hose-spigot sprinkler setup ever okay?
Only if there is a proper backflow. Most DIY hose setups do not have one. Without it, you risk contaminating drinking water inside the house.
When should I stop DIY and hire a pro?
If you are not familiar with how irrigation works, hire a professional for install, winterizing, and pressurizing. Uniform precipitation, zone timing, wiring, heads, and backflow are not hardware-store guesswork.
How much does professional winterizing cost?
About $125 to winterize properly. That is cheap insurance next to freeze damage, a cracked hose bib, and indoor flooding.
