"More calls is more money" is the most expensive assumption most plumbing owners are still operating on.
That's the through-line of Episode 310 of The Fresh Approach Podcast, where Chris Fresh tears apart the scheduling habits that look like productivity but quietly bleed revenue. And the punchline at the bottom of the episode is the one most owners aren't ready to hear:
Less calls is more money.
Not always. Not in every market. But more often than the schedule board in most plumbing shops is currently reflecting. Here are the two scheduling rules Chris walked through on that episode — and they apply whether you're a one-truck operation or a multi-location $80M shop.
Rule 1: Leave Space for the Emergency Call
Here's how most plumbing schedules get built. CSR takes calls all morning. Slots fill up fast. By 1 PM, every truck is booked through Friday.
Then the phone rings at 1:15 PM. Customer says: "I just got home from lunch and my water heater is sitting in two inches of water in the garage. Can someone come today?"
That's the call. That's the customer who's going to convert at $4,800 today because there's a real problem and zero time to comparison-shop. And your schedule is full of the four-month-old leaking valve, the "thinking about a pool heater next year" call, and the customer with twelve parts on her tub waiting for your plumber to put them all back together.
Chris's first rule: leave one afternoon slot open every day for the emergency call. Train the CSR to filter not by job type, but by urgency. "How long has this been going on?" is the question. If the answer is "I just found it," that's the slot. If the answer is "a couple months," that goes on Thursday.
Chris ran the numbers on his own plumbing company after he installed this rule: three or four times a week the emergency call came in. The other day or two, no emergency, and the tech went home early. Same paycheck. Better culture. And the math worked — running three emergency calls produced more net revenue than running five non-urgent calls. Plus the tech who got home early loved the company more than the one who burned out chasing fill valves through dinner.
Rule 2: Book the Day With Opportunity, Not Volume
This is the rule that hurts owners' feelings, because it forces them to look at their own scheduling board and admit half the calls on it are wasting the day.
Chris's framing: if you've got the capacity to handle 20 calls a day, 20% of them can't be non-opportunistic. Customer calls in to scope a sewer line on a house she might buy. Customer wants you to run a gas line for the pool heater she'll install in five years. Customer wants you to look at the part she ordered off Amazon and figure out if it'll work.
Those aren't bad calls. They're future revenue. But you don't want 10 of them on the same day.
Chris saw a real example on a coaching client's schedule that he shared in the episode. The schedule had ONE actual opportunistic call on it. The rest were recalls, a sewer scope for a home a customer was thinking about buying, and a call about a heater for a pool the customer didn't even own yet. Half the day, on paper, was "work." Half the day, in revenue terms, was a wash.
The fix: spread the peanut butter. Take those non-opportunistic calls and disperse them across different days instead of clumping them into one. One pool-heater consultation Monday. One sewer scope Wednesday. One recall Friday. Now Tuesday and Thursday have room for the customer who's actually ready to spend money.
What 85% Conversion at $1,500 a Call Actually Looks Like
One of the specific numbers Chris drops in this episode is from a real coaching client running this scheduling discipline. 85% conversion rate at $1,500 a call — including the zeros.
That's not the top performer. That's the company average, lowest performers included. Most plumbing companies are at 50–60% conversion at $400–$600 a call, which means this company is roughly 2.5x ahead on conversion AND 3x ahead on ticket average — same trucks, same techs, same town.
The difference isn't a slicker sales script. The difference is the day on the schedule was set up to win before anyone left the yard. Emergency slot open. Opportunity calls in the heavy slots. Non-opportunistic calls spread across the week instead of clumped.
That's what Chris means when he says tracking the right numbers is what unlocks real growth. Calls per truck per day looks like productivity but it's a vanity metric. Convertible calls per truck per day is the real lever.
Rule 3: Less Driving, More Wrench Time
This is the one Chris almost slips in at the end of the episode, but it's the deepest rule in the lot.
If your tech is running four or five calls a day, they're driving most of the day. Drive 30 min. Diagnose 30 min. Work 45 min. Pack up. Repeat. By the end of an 8-hour day they've spent half of it in the truck.
Compare that to a tech who runs one or two calls — they're driving an hour total and spending six and a half hours in the home generating revenue.
Same daily wage. Wildly different production hours. Same pricing structure. The two-call tech can charge a softer hourly burden and still net more revenue per day because they're producing more billable minutes. The five-call tech needs a higher hourly rate just to break even — and a higher hourly rate means harder conversions.
This is why the schedule discipline matters more than the price book in the order of operations. Fix the schedule, and the price book gets easier. Fix the price book first, and the schedule will sabotage it.
Three Habits to Start Tomorrow
1. Tell your CSR to leave one afternoon slot open every day this week. Filter incoming calls by urgency, not by job type. "How long has this been going on?" is the question. "I just found it" books today; "a couple of months" books Thursday.
2. Audit tomorrow's schedule for opportunistic calls. Count the calls on the board. How many are real revenue opportunities and how many are recalls, pool-heater-in-five-years consults, or part-verification visits? If you're under 50% opportunistic, spread the non-opportunistic ones across the week.
3. Pull last week's calls-per-truck-per-day and last week's revenue-per-truck-per-day side by side. The truck that ran the most calls probably isn't the one that produced the most revenue. That's the data point that converts the "more calls is more money" believers in your shop.
Key Takeaways
Leave one afternoon emergency slot open every day. Emergencies are the highest-converting customers; clumping the day with non-emergencies blocks them.
Book the day with opportunity, not just activity. Half a day of recalls and pool-heater consults isn't a day — it's an expensive distraction.
Spread the peanut butter. Disperse non-opportunistic calls across the week instead of clumping them in one day.
Less driving, more wrench time. The two-call tech produces more revenue than the five-call tech, with a softer hourly rate.
Convertible calls per truck per day > total calls per truck per day. That's the metric that actually moves the business.
