Before you leave for vacay, make sure these automatic home systems won’t waste water while you’re away.
It can be quite a shock to take vacation and return to a huge water bill a month later. Where could all the water possibly have gone while we were out of town?
It happens every year and summer is a time to be careful, especially if your home features in-ground irrigation. Your family members aren’t the only ones in the house using water.
There are at least three automatic home systems using water on their own. And one of them can double — or possibly triple — your water bill.
Irrigation: In-ground sprinkler systems, by far, are the biggest water users in the home in summer. They can use as much water in a single cycle as your entire family uses in one month. So before you leave for vacation, check it!
- How many cycles per day are the sprinklers running?
- How many cycles per week?
- Are sprinklers running morning and evening?
- How many programs are running?
- Is there a seasonal adjust? Does it having a monthly schedule? Controllers with scheduled seasonal adjustments may increase from 50 percent in spring to 100 percent during summer, effectively doubling your water bill. Don’t make a guess — check it!

Ideally, you’d like to be able to use a single cycle per week (of course, no two yards are alike, and some are very large). A few basics to remember:
- Don’t turn the irrigation up “just to be safe.” Adding one extra cycle effectively doubles your water bill.
- Don’t assign sprinkler controls to a neighbor, gardener or relative. Instead, ask them to water by hand.
- Don’t set drip to water every day.
- Don’t assume the sprinklers are smarter than you. “Smart” controllers may adjust the irrigation schedule on their own during hot weather, based on built-in formulas and assumptions. Instead, disable smart watering features and use a fixed schedule instead.
If you still don’t know how much water sprinklers use in gallons, prepare to have your mind blown. Just take a meter read before and after your next sprinkler cycle and multiply by four to see how much it’ll use in a month. It’s not uncommon for sprinklers to use 15 or 30 gallons per minute and anywhere from 2,000 gallons to 10,000 gallons per week.
Here’s a few other water-wasting culprits to look out for before you leave town.
Water softeners: The backwash on a water softener runs either on a nightly schedule or an interval schedule whenever the tank gets low. If you find the water softener never stops running, it’s leaking. Bypass it until you can have it repaired.
Automatic pool refill: If you’re not putting a hose and timer out there regularly, yours may have an automatic refill feature. Your pool service can confirm this. If so, have them confirm there are no leaks, because a running pool can use a lot of water.
Leaks: Some homeowners shut their water off at the street when they leave town. While this may sound extreme, it can protect against leaks. If you’re worried you may have leaks, your Connect H2O meter will easily confirm it. The water meter is in the ground, normally out by the street or the alley. Make sure the water is off and then look for the GPM reading. It should read zero, unless there’s water passing through the meter. Even the slightest flow will add up if it’s left uncontrolled over the course of a week or two.
