For some people, the sound of a sprinkler running means summer has arrived. It's the quintessential sound of an early morning, a gentle swishing as the neighborhood keeps its lawns healthy and looking their best.
However, others may find being woken up by the very same noise can be pretty irritating. If a sprinkler is broken, that gentle sound can become an annoying tapping that has the potential to start arguments with the neighbors.
I spoke to a lawn care expert about the best time to run a sprinkler to keep everyone in your neighborhood happy.
When is it antisocial to run a sprinkler?
The most pro-social time to run a sprinkler isn't necessarily the best time for your grass. For lawn health, the best time is in the early morning, between 6am and 9am. This is because temperatures are cooler, which means less water evaporates after watering, so your grass can absorb more water and is healthier. Conversely, watering at night means that grass roots stay damp overnight, which can encourage rot and fungal growth.
To add to this, cheap plastic sprinklers are good for saving money, but they're particularly bad for low-level clicking and grinding noises, which can quickly become antisocial. In the rare occasions that something goes wrong with your sprinkler and air backs up in the hose, sprinklers can make incredibly loud whining sounds.
It's often best to turn sprinklers on in the early evening for the sake of neighborhood harmony. It's cooler, so water is less likely to evaporate than earlier in the day, but there's still time for some evaporation to take place, so you won't encourage fungi.
Lawn expert Kody Ketterling told me 'We always suggest running the sprinklers after the cool down - which is 6pm - and then make sure we are finished running them by about 9pm. We suggest that if you run them while people are sleeping that you check them every couple weeks to once a month to make sure they are operational and working correctly. If the sprinklers malfunction or have any issues late at night this may disturb the neighbors, so be mindful to make sure the system is fully operational.'
If anything goes wrong, you're also less likely to disturb anyone. If you know your neighbors have young kids and aren't getting much sleep, or if things are a little tetchy for some reason, evening watering can stop arguments before they start.
Are there any laws on when you can run a sprinkler?
On top of the sociable hours, you may find that local laws mandate when you can and can't use your sprinkler. These can vary hugely from county to county and are often put in place to ensure that people run their sprinklers at sociable times.
Kody Ketterling told me that 'A lot of areas have put in ordinances such that you cannot run sprinklers during the daytime hours of 10am through 5pm. Cities may set restrictions where odd-numbered houses can run sprinklers on Wednesday, Friday, and Sunday, and even-numbered houses on Tuesday, Thursday, and Saturday, all with set hours of watering.
'We have also seen split hours, allowing some to water late at night and some in the morning. It really depends on the city rules and regulations,' he continues.
However, Kody told me that there are some exemptions. He told me that if you're sourcing your gardening water from a well on your own property, you're exempt from the city laws regulating water use. There are also different rules if you use drip irrigation for your plants. Kody says 'A lot of places will allow you to run drip every day because drip is usually a lower volume of water for bushes, pots, hanging baskets, and trees.'
This simple sprinkler has a sturdy metal base that should last for years. It has tens of thousands of five-star reviews, and while people say it takes a little getting used to, once it works its very low-maintenance.
A tripod sprinkler like this is great for watering large lawns and reaching all the way to flowerbeds ion the other side of your lawn.
If you want a low-profile sprinkler that doesn't show up in your lawn or flowerbeds, this cheap sprinkler on a spike is perfect.
Can your HOA tell you when to run a sprinkler?
In addition to local ordinances, there are also rules from homeowners' associations to bear in mind. HOAs often have rules about when and where you can run your sprinkler.
Kody says 'We have seen fines and other penalties enforced by HOAs if guidelines are not followed. If fines are not paid HOAs can seek legal action or put a lien on your property. I know of homeowners who have tested the guidelines but usually have lost in the end. Some HOAs have their own holding ponds or water and they control when they run the pumps to have water for the yards.'
The good news, however, is that HOA rules make it an even playing field. If you run your sprinkler during the times mandated by your HOA, it may annoy a neighbor, but you're well within your rights, so it's an interpersonal issue rather than a legal one.
What can you do if your neighbor's sprinkler system is waking you up?
If your neighbor's sprinkler system is disturbing you, your first port of call is to let them know. Sprinklers tend to make noise if they're broken, so your neighbor will probably appreciate the heads-up that there's something they need to fix. If the sprinklers are running on an automatic system, your neighbors may not have noticed that they're making noise.
Even if the issue is a sprinkler that's loud as it's running, most people are happy to make small accommodations like changing their watering schedule a little. However, not everyone is open to this.
Kody says 'If you can't reach a resolution you may need to involve your HOA or take legal action. I have never heard of it going that far, but I'm sure it happens. Usually, the nice approach works and homeowners strive to be good and friendly neighbors. Make sure it is definitely the neighbor's sprinklers causing the disturbance before you bring it up to them.'
