The Hidden Gold Mine in Your Customer List
Every water heater you install is a future service call waiting to happen. Tank water heaters need flushing every 12 months. Anode rods need replacing every 3–5 years. And every unit eventually needs replacement.
But here's the problem: most plumbers never follow up.
The Math That Changes Everything
Let's say you install 10 water heaters per month. That's 120 customers per year. If you charge $149 for an annual flush and maintenance:
- Year 1: 120 customers × $149 = $17,880
- Year 2: 240 customers × $149 = $35,760
- Year 3: 360 customers × $149 = $53,640
That's recurring revenue that compounds every single year — from work you've already done.
How to Set Up Automated Reminders
With a CRM like GoHighLevel, you set this up once and it runs forever:
- Tag every water heater install in your CRM with the install date and unit type
- Create an automation that triggers 11 months after install
- Send an SMS + email reminding them it's time for their annual flush
- Include a booking link so they can schedule in one click
- Follow up 3 days later if they haven't booked
Sample Reminder Text
Hi [Name]! It's been almost a year since we installed your water heater at [Address]. Annual flushing extends the life of your unit by 3–5 years and prevents sediment buildup. Book your $149 maintenance visit here: [Link] — [Company Name]
Why This Works So Well
- Customers appreciate the reminder — they didn't know they needed maintenance
- You look professional and trustworthy — proactive, not reactive
- The booking link removes friction — they schedule in 30 seconds
- It's 100% automated — zero time investment after initial setup
Stop leaving money on the table. Your past customers are your best customers.
