Plumbing Seasonal Playbook

Updated · 11 min read

The short answer

Plan the plumbing year around cold and water. Before the first hard freeze, send customers prevention tips and set an on-call rotation for frozen and burst pipes that also covers the thaw. In spring, check sump pumps and outdoor faucets. In summer, handle irrigation, hose bibs and empty houses, and book planned work. In fall, winterize outdoor plumbing and service water heaters. Staff up for holiday kitchen clogs, and let maintenance plans fill the slow weeks.

How the plumbing year runs

Plumbing demand follows cold and water, and most of the calls can't wait. Get ready before each season: messages written, trucks stocked, phones covered and a triage order everyone knows.

Season What the phones bring Owner's focus
Winter (December to February) Frozen and burst pipes, thaw leaks Freeze messages, triage, on-call rotation, freeze kits
Spring (March to May) Sump pumps, split outdoor faucets, irrigation start-ups Sump and faucet checks, backflow tests
Summer (June to August) Irrigation and hose bib leaks, high water bills, empty houses Leak checks, vacation homes, planned projects, hiring
Fall (September to November) Winterizing, water heater service Outdoor shutdowns, water heater flushes, winter staffing
Holidays (late November to early January) Kitchen sink, disposal and main line clogs Drain messages, holiday on-call, drain stock

Note: This calendar assumes hard freezes. Slide it to match when your phones actually got busy last year.

Winter: frozen and burst pipes

Water expands as it freezes, and a pipe full of ice can split. Freeze calls differ from other emergencies in two ways: the water runs until someone shuts it off, and some of the damage doesn't show up until the cold has passed.

Send prevention tips before each cold snap

When the first hard freeze shows up in the forecast, and before each cold snap after it, send customers what they can do tonight:

  • Find the main shutoff, make sure it turns, and show everyone in the house where it is.
  • Disconnect garden hoses from outdoor faucets.
  • Open kitchen and bathroom cabinet doors so warmer air reaches the pipes, and on the coldest nights let cold water drip from a faucet at a trickle 1.
  • Keep the garage door closed if water lines run through it, and leave the heat on when traveling.
  • If a faucet won't run, leave it open and warm the pipe with an electric heating pad, an electric hair dryer, a space heater kept away from anything flammable, or towels soaked in hot water. Never use a blowtorch, a kerosene or propane heater, a charcoal stove or any other open flame 1. Call us if you can't find or reach the frozen section.

Keep a separate list of at-risk homes: pipes in crawl spaces, garages or outside walls, houses that froze before, and second homes that sit empty. Those customers get a phone call, not just a text. How to get more plumbing customers covers making seasonal messages a habit.

Triage freeze calls on the phone

Set the order now and train everyone who answers the phone or replies to texts:

  1. Water running now. Talk the caller through closing the main before you dispatch. A vacant house or second home goes to the top, because nobody is inside to close the valve.
  2. No water in the house. A frozen supply line, or a main closed while a burst pipe waits for repair. Ask whether anyone home is older, ill or caring for an infant, and move them up.
  3. One frozen fixture. With water everywhere else, it can take a scheduled window, plus the thawing tips and a reminder of where the shutoff is.
  4. Planned work. Move it to after the cold snap and call each customer to explain.

Tip: Ask callers to text a photo of the leak and the shutoff. The plumber sees the pipe and the access before leaving, and you can confirm the water is off.

Plan for the thaw, not just the freeze

A split pipe may not leak while it's frozen, because the ice plugs the crack. The leak starts when the pipe thaws, sometimes inside a wall or ceiling, so a cold snap can bring a second wave of calls on the day temperatures climb back above freezing. Keep crews available for the thaw, and tell every customer with a frozen pipe to watch for water as it warms up.

Example: Say three trucks can each finish four freeze calls a day, counting drive time: 12 a day. A cold snap brings 20 requests a day for two days, then 30 on the thaw day: 70 requests against 36 slots, so 34 callers wait. A plan written in October closes most of the gap: two plumbers on overtime take two extra calls a day each (12 more over three days), and your installer joins the rotation for four a day (another 12). The last 10 are talked through shutting off their water and given an honest arrival window for the next day.

Set after-hours and emergency prices before the season so anyone on the phone can quote them; how to price plumbing jobs covers emergency premiums and trip fees.

Stock a freeze kit on every truck

Stock each truck to last winter's parts usage before the first hard freeze: repair couplings and fittings for every pipe material in your area's homes (including the old ones you only meet in crawl spaces), shutoff valves, frost-free outdoor faucets in common stem lengths, pipe insulation, heat cable, thawing equipment and a wet vacuum. Ask your supply house before winter what it will hold for you, because every plumber in town wants the same fittings on the first cold morning. Plan for the crew too: dry gloves, spare clothes and warm-up breaks.

Document every freeze repair

Customers with water damage may file an insurance claim and need a clear record. Photograph the break before you repair it, note the pipe material, location and cause, and keep the failed section if they ask. Don't tell them what their policy covers. How to invoice plumbing jobs covers what goes on the invoice.

Spring: sump pumps and outdoor faucets

Check sump pumps before the spring rains

In many markets, snowmelt and spring rain give sump pumps their hardest workout, and a pump that died quietly over winter gets found out by a wet basement. Offer checks in late winter and work from one list:

  • Fill the pit and confirm the float starts the pump, the pit empties and the pump shuts off.
  • Confirm the check valve keeps water from draining back into the pit.
  • Follow the discharge line outside: clear, not frozen at the outlet, and carrying water away from the foundation.
  • Clean debris from the pit, test any battery backup and high-water alarm, and note the age of the pump and the battery.

Before you reroute a discharge line, ask your sewer utility or building department where sump pumps may discharge. In your spring message, tell customers to pour a bucket of water into the pit and call you if the pump doesn't start.

Test outdoor faucets for freeze damage

A frost-free outdoor faucet protects itself only if it can drain. If a hose stayed connected all winter, water trapped in the long stem can freeze and split it inside the wall, and nothing leaks until someone opens the faucet in spring. Tell customers that the first time they use each outdoor faucet in spring, they should connect the hose, turn it on and check inside for drips. When you replace one, slope it slightly down toward the outside so it drains.

Irrigation start-ups and backflow tests

Lawn irrigation is a textbook cross-connection: it ties the home's drinking water to pipes buried in soil and fertilizer. That's why irrigation systems commonly carry backflow preventers, and why start-up is the time to check one for freeze damage. Testing rules are set locally, so ask your water utility how often assemblies must be tested, who may test them and how results are filed. If you hold the certification your area requires, start-up season is a reason to call every irrigation customer. Backflow preventer explains the device and how testing works.

Summer: irrigation, hose bibs and empty houses

Help customers find real leaks

Summer watering pushes water bills up, and customers call to ask whether it's a leak. Teach them two free checks from EPA's WaterSense program:

  • Meter test. Read the water meter before and after a two-hour period when no water is being used. If it changed at all, there's probably a leak 2.
  • Toilet dye test. Put a drop of food coloring in the tank. If color shows up in the bowl within 10 minutes, the toilet leaks, usually past the flapper. Flush afterward so the dye doesn't stain the tank 2.

Hose bibs and backsiphonage

Water from a hose left in a bucket of soapy water, a pool or a fertilizer sprayer can be siphoned back into the home's piping if water pressure drops, for example during a water main break. On summer visits, check for hose connection vacuum breakers where your local code requires them.

Vacation homes and empty houses

A leak in an empty house runs until someone comes home. Give travelers a short checklist: close the main shutoff for any trip longer than a few days (unless fire sprinklers are fed from the same supply), set the water heater to vacation mode, and leave a neighbor the shutoff location and your number.

Second homes in cold regions are a route business of their own. Closing one in fall means draining the water lines and the water heater and protecting traps and toilets with non-toxic RV antifreeze. Opening it in spring means refilling slowly, checking every fixture and visible pipe for freeze damage, and restarting the water heater only after the tank is full. Book these as a block, and sell the fall closing at the spring opening.

Use slower weeks for planned work and hiring

If emergency calls ease off in your summer, fill the schedule with repipes, planned water heater replacements, fixture upgrades and remodel rough-ins, with proposals sent in spring; see how to write a plumbing estimate. Hire for winter now, too. A plumber hired in January learns on burst pipes with no time for ride-alongs, so hire by early fall; hiring your first plumber covers the process.

Fall: winterize and service water heaters

Shut down outdoor plumbing before the first freeze

Book winterizing visits early, before the first hard freeze forecast fills your phone. A standard visit:

  • Disconnect hoses and drain the outdoor faucets. On faucets that aren't frost-free, close the inside shutoff and open the outside faucet to drain the line. Replace damaged faucets with frost-free models.
  • Drain or blow out the irrigation system (or confirm the customer's irrigation company has), and protect the backflow assembly as its manufacturer directs.
  • Insulate exposed pipes in crawl spaces, garages and attics, seal gaps where cold air reaches them, and add heat cable where needed, following the cable manufacturer's instructions.
  • Exercise the main shutoff and replace it if it won't close fully. That valve is the difference between a small leak and a flooded floor.

Service water heaters before the cold

Incoming water is colder in winter, so the heater works harder for the same shower, and a weak one can start running out of hot water in January. A fall visit:

  • Flush sediment from tank heaters following the manufacturer's instructions.
  • Test the temperature and pressure relief valve, and carry a spare, since an old valve may not reseat.
  • On gas units, check the venting and burner area for rust, scorching or loose connections.
  • Descale tankless units on the manufacturer's schedule, especially where the water is hard.
  • Record the make, model, serial number and age.

That record sets up the replacement conversation. A customer told in October that a tank is near the end of its life can plan and compare options; one whose tank fails on Christmas Eve gets whatever is on your truck. How to price plumbing jobs covers pricing replacements, including the code-required items your jurisdiction calls for.

Holidays: kitchen drains and full houses

Holiday cooking and houseguests load up kitchen drains, garbage disposals and guest bathrooms. Grease poured down the sink cools and hardens in the pipe, scraps build up on it, and a main line that was barely keeping up backs up mid-gathering.

Send a pre-holiday drain message

The week before Thanksgiving, send customers a short list:

  • Pour cooled grease into a container and throw it out, never down the sink.
  • Scrape plates into the trash before rinsing.
  • Keep grease, bones, peels and stringy scraps out of the disposal.
  • Flush only toilet paper, and put a plunger in every guest bathroom.

Staff and stock for the holiday rush

Holiday calls land on the days your team most wants off. Post the holiday on-call schedule by early November, rotate the big days from year to year, and pay a premium for holiday on-call. Quote your posted after-hours rate before you dispatch, and stock the on-call trucks with the cables and cutters you use on kitchen lines, trap parts and a spare disposal.

Clear the line, then find out why

A main line that backs up during a holiday may point to roots, a sag or a broken section. After you clear it, offer a camera inspection, and price the clearing and any repair separately so the customer can decide on the repair after the holiday.

Plan staff and parts from last year's calls

Pull last year's calls by week and type (frozen and burst pipes, thaw leaks, sump pumps, outdoor faucets, water heaters, drains, main lines) and mark the weeks when calls outran your trucks. That tells you when to post on-call rotations and approve time off, when to hire, what each truck needs each season, and when to send each message: a few weeks before last year's spike, not the morning it starts. If those calls come in by text, Redline, chat-first field service software, includes dispatch for getting urgent calls to the right truck.

Cash flow: make the slow weeks pay

Slow weeks still carry rent, insurance, truck payments and payroll. A plumbing service agreement built from this playbook puts paid work into those weeks: a fall visit for the water heater flush and winterizing, a spring visit for the sump pump and outdoor faucets, and priority service when a pipe bursts. Members also have a reason to call you first.

Example: Suppose 200 customers join a plan at $15 a month. That's $3,000 a month, or $36,000 a year, whatever the weather does. Two visits each means 400 visits to schedule. Spread over 10 fall weeks and 10 spring weeks, that's 20 a week: about four a day for one plumber.

Collect on emergency calls at the time of service, and set aside part of each busy week's revenue for the slow ones. Cash flow explains why a strong winter can still leave the account thin by summer.

Before each season: a short checklist

  • By February: sump checks booked, spring faucet and irrigation messages written, backflow reminders ready if you're certified.
  • By May: traveler checklist ready, summer project proposals out, hiring plan set.
  • By September: winterizing, water heater visits and second-home closings booked, new hires riding along.
  • By November: freeze kits stocked, triage trained, on-call and holiday schedules posted, after-hours rate set, freeze and drain messages ready.

Common questions

Can I raise my prices during a cold snap?

Set your after-hours and emergency rates before winter, make sure everyone who answers the phone quotes the same numbers, and tell each customer the rate before you dispatch. Raising prices in the middle of an emergency costs you trust you'll want back in spring. If your state or city declares an emergency, check with your state attorney general's office before you change any rates, and ask a lawyer if you're unsure.

Should my company handle water damage cleanup too?

Decide before winter, not while standing in a flooded basement. Drying out a house is its own line of work, with its own equipment, training and insurance paperwork. If you don't want to build that, line up a local restoration company you trust, agree on how you'll refer customers to each other, and hand the customer their number on the same visit.

How do I adjust this calendar for a warm climate?

Start from your call history, not the calendar. Where hard freezes are rare, irrigation and outdoor plumbing may run most of the year, and the winter section shrinks to a short plan for the occasional cold snap. Keep that plan anyway: the shutoff script, a freeze kit on each truck and a prevention message ready to send whenever a hard freeze shows up in the forecast.
