# Summer Plumbing Calls I'd Rather Not Get (and How You Avoid Them)
Your system's about to get hammered. Sprinklers running full-time, disposal grinding through cookout scraps, kids home all day flushing wipes, guests showering before they hit the pool. If your plumbing's got a weak link, July will find it.
I've been pulling clogs and chasing leaks in this heat for fifteen years. The calls I get in summer are predictable—same stuff, different address. Most of it you can head off yourself if you know where to look.
The Sprinkler System You Haven't Thought About Since April
Irrigation's the number one callback I get once it heats up. Homeowner's watering every other day, water bill doubles, and they don't notice the head that's been misting the driveway for three weeks.
Walk your zones. All of them. Look for:
- Heads spraying sideways or fogging instead of throwing a clean pattern
- Wet spots in the yard when the system's off
- Pressure that seems weak on one zone (valve's probably clogged or a lateral line's leaking underground)
Broken sprinkler heads are cheap. The 500 gallons a day you're pumping into the ground while you ignore it isn't. Neither is the trench work to find a split lateral six inches down.
If you've got a valve box, pop the lid and check for standing water. Valve diaphragms tear, and you won't know until you're looking at it. I've seen guys burn through $300 in water before they figured out one zone was weeping 24/7 through a bad valve.
And for the love of God, don't scalp the grass around the heads with the mower. Half the broken risers I replace got clipped by a deck because somebody wasn't paying attention.
Your Garbage Disposal Is Not a Garbage Can
This is the hill I will die on.
Summer means cookouts. Corn husks, watermelon rinds, burger grease, pasta salad that sat out too long. Disposal runs fine in March because you're grinding coffee grounds and banana peels. Then you hit it with three ears' worth of corn silk and cob bits on a Saturday and it jams, or worse—it doesn't jam, just pushes the pulp into the trap and you're calling me Sunday morning when the sink's backed up into the dishwasher.
Disposals work harder in summer because *you're* working them harder. They're not designed for volume. A continuous-feed 3/4 HP unit will handle normal kitchen scraps. It will not handle the aftermath of feeding eight people.
Grease is the killer. It goes down liquid, cools in the trap, and builds up. You think you're flushing it with hot water. You're not. You're moving it eight feet down the line where it hardens.
Run cold water when you grind anything. Not hot. Cold keeps the grease solid long enough to chop it and move it out. And use the disposal for what falls in while you're rinsing—don't scrape the plate into it.
Couple times a month, toss some ice cubes and a half lemon in there and let it rip for thirty seconds. Keeps the impeller clean and kills the smell. That's it. You do that and don't abuse it, you'll get ten years out of the thing.
Water Heater Sitting There Heating Water Nobody's Using
You leaving for a week? Longer? Flip your water heater to vacation mode or just turn the thermostat way down.
Gas units usually have a vacation setting on the dial—drops it to pilot-only or just barely warm enough to prevent freeze damage (which you don't need to worry about in July). Electric, you're turning the breaker off or dialing both thermostats down to 50°.
Why: you're heating 40 or 50 gallons for no reason. Costs you a few bucks a day, and if something *does* go wrong while you're gone—relief valve weeps, tank springs a pinhole, supply line decides it's done—you're flooding with hot water instead of cold. Not really better, but the scalding puddle doesn't help.
I've walked into a basement where the relief valve had been dripping for days while the heater kept reheating the same water and cycling constantly. Burned out the thermocouple on a gas unit. Whole thing could've been avoided.
Shut the cold supply valve if you're going to be gone more than a week and you're paranoid. I do it. Tank can't flood if there's no pressure feeding it.
Check Your Washing Machine Hoses Before They Check Themselves
Washing machine hoses fail *constantly*. Rubber supply hoses dry-rot. Doesn't matter if they're new three years ago—they're sitting there flexing every time the valves cycle, baking under whatever heat your water heater's putting out, and one day the inner layer bubbles and splits.
Most failures happen when the machine kicks on and pressure spikes. You're at work. The valve's wide open. 60 PSI is now dumping onto your laundry room floor until somebody notices or the utility calls because you've pushed 8,000 gallons.
Braided stainless hoses. Replace the rubber ones. Worth the $25. Check them every couple years anyway—if the crimps are corroding or the braid's fraying near the fitting, swap them.
And if you're leaving for more than a couple days, shut the valves. Both of them. Takes ten seconds. I've seen flooded basements from washing machine blowouts where the homeowner was two states away. Insurance paid, but the drywall and subfloor didn't come back perfect.
The Sewer Line That's Been Choking for Months
You don't think about your sewer line until it's backing up into the tub or the yard's got a wet spot that smells like hell.
Summer's when it shows up because water use spikes. More showers, more laundry, more dishes. System that was moving everything fine in April starts gurgling when you drain the tub because tree roots have been growing into the terra cotta since March and now there's no margin left.
If your main's old—cast iron from the '50s, clay tile from the '60s—you've got root intrusion. Guarantee it. Roots follow moisture. They find the joints, they get in, they grow a mat, and everything slows down.
Toilets flush slow, drains gurgle, laundry backs up into the standpipe. That's your sewer telling you it's 70% blocked.
Hydro jetting clears it. Snaking buys you six months if you're lucky. If the line's collapsed or the bellies are bad, you're digging it up or pulling a liner. That's not a summer project you want to tackle in a panic when the family's in town and the house smells like sewage.
Get it scoped if you've got an old main and you're seeing symptoms. Camera run's a couple hundred bucks and tells you what you're dealing with. Then you can plan for it instead of reacting at the worst possible time.
The Toilet Everyone's Flushing Wipes Down
"Flushable" wipes are not flushable. They don't break down. They sail right through the trap, get into the stack, snag on a rough spot or a root hair, and the next one catches on that one. Three months later you've got a rag in your line and I'm pulling the toilet.
Kids home for summer, guests over for the weekend, somebody's flushing them. I see it every year.
If you've got wipes in the house, put a trash can with a lid in every bathroom and tell people to use it. You can't police it, but you can make it easy.
Worst callback I ever had was a rental property where the tenant's kids had been flushing wipes for a year. Main line backed up into the basement laundry sink during a party. I pulled 30 feet of snake out with a wad the size of a football on the end. Looked like paper mache made of ass rags.
Don't be that guy.
Hose Bibs and the Fifty-Year-Old Valve Behind Them
Your outside faucets—hose bibs—get beat to death in summer. Hose stays connected, somebody cranks it shut too hard, the packing nut's loose, the vacuum breaker's cracked.
If it's dripping from the handle, tighten the packing nut (that's the nut right behind the handle). If that doesn't fix it, you need to repack it or replace the valve.
If it's leaking from the spout when it's shut off, the seat washer's shot. That's an easy fix if you've got a rebuild kit and a seat wrench. Most guys just replace the whole bib for $15 and twenty minutes.
Check the one on the front of the house and the one in back. If they're original to a house built before 2000, I'd replace them with frost-free sillcocks anyway. It'll save you a freeze call in January when you forget to drain it.
And for Christ's sake, don't leave the hose connected when you're not using it. Back pressure can siphon crud into your supply line if the vacuum breaker's missing or cracked, and nobody wants to explain to the county why their irrigation water tested positive for fertilizer.
What You Should Ignore (For Now)
Your water heater's going to die someday. So's your softener. So's the 30-year-old gate valve feeding your second-floor bath.
If it's not leaking and it's not throwing errors, leave it alone for now. Summer's not when you want to get into a replacement unless you have to. It's hot, supply houses are slammed, and you're paying peak-season rates if you're hiring it out.
Make a note. Plan for fall. But don't go looking for problems that aren't there yet.
The Real Cost of Ignoring This Stuff
Every flooded basement I've walked into started with something small. A drip somebody didn't fix. A clog they kept plunging instead of clearing. A sprinkler head they knew was broken but didn't feel like dealing with.
The ten-minute fix becomes the three-day disaster because it's easier to ignore it than to drag the ladder out or crawl under the sink.
I get it. But I also get paid $175 an hour to show up, and my schedule's packed through August because everybody's got an emergency that wasn't an emergency two months ago.
Your call.
