How to Track User Retention for Plumbers

A homeowner calls you for a leaking pipe. You fix it fast, charge fairly, and they thank you profusely. Six months later, their water heater fails. Do they call you, or does a neighbor’s recommendation lead them to someone else? User retention tracking tells you the answer.

Why User Retention Matters for Plumbers

Emergency calls repeat. Once a pipe bursts or a water heater dies, the same home often faces related issues within 12-24 months. Clients who trust you for one emergency call will trust you for the next.

Maintenance contracts create steady income. Offering annual inspection plans locks in revenue before problems occur. Tracking retention shows how many clients renew each year.

Word-of-mouth multiplies. A loyal plumbing client recommends you to family and neighbors. That one relationship can generate 3-5 new calls over time.

Marketing costs drop. Acquiring a new customer costs 5-7 times more than keeping an existing one. If you retain 70% of clients, you spend less on Google ads and more on trucks and training.

How to Check in GA4

Open GA4 and navigate to the Retention report. Set the date range to at least 180 days since plumbing issues often follow seasonal patterns.

Switch to the User Retention view. Look for users who converted twice or more. These are your repeat clients.

Segment by conversion type. Separate drain cleaning from water heater installation. This shows which services lead to long-term relationships.

Add a custom dimension for “service type” when tracking conversions. Then compare retention across different job types.

The Easier Way

ClawAnalytics builds retention reports automatically from your service data. You see which clients called multiple times and which haven’t reached out in over a year.

Plumbers frequently ask:

• Which clients had service done 8 months ago and might need follow-up maintenance?
• What’s my client lifetime value based on average repeat calls?
• Which zip codes have the highest concentration of loyal clients?

The platform sends alerts when a long-time client hasn’t booked recently, so you can reach out with a seasonal inspection offer.

Quick Wins

Create a maintenance plan. Offer annual water heater flushes or sewer inspections. Clients on plans retain at 80%+ rates.

Leave behind a follow-up card. Include your number and a reminder about seasonal services like winterizing pipes.

Text after service. A quick “Thanks for choosing us. Call anytime for future plumbing needs” keeps you top-of-mind.

Track every job in your CRM. Even small drain clogs count. Over time, this data reveals patterns in when clients need you next.
