What you can observe, why it needs evaluation, and the next step
| What you can see or hear | Why it needs evaluation | Safe next step |
|---|---|---|
| Manometer fluid sits level with no offset | The indicator is not showing the documented pressure difference. Fan, tubing, power, or airflow issues are possible, but the cause cannot be determined from the indicator alone. | Request an on-site evaluation and retest after repair or modification. |
| Fan is loud, grinding, or vibrating | Abnormal noise or vibration can have more than one cause and requires an on-site evaluation. | Request an on-site system evaluation. |
| Fan runs but a recent test is 4 pCi/L or higher | Fan operation alone does not show whether the system is reducing the indoor concentration adequately. | Review whether the result is an initial or confirming test and request an on-site system assessment. |
| Visible water is sloshing in the pipe | Water in the vent path can interfere with system operation, but its source and the required correction must be evaluated on-site. | Request an on-site system evaluation. |
| A pipe joint is separated, cracked, or visibly open | The vent path is visibly damaged or open, but the repair scope depends on its location and the system design. | Request an on-site system evaluation and repair. |
| The system was turned off during other work and has not resumed normal operation | The active system may not be operating. The indicator, fan, and power configuration require evaluation. | Request an evaluation before opening, rewiring, cutting, or reconfiguring any component. |
The cause of a system problem—including fan condition, airflow, pressure, drainage, pipe routing, and whether the indoor radon level remains elevated—must be evaluated on-site. Do not open, cut, rewire, or reconfigure system components based on this table.
Iowa's rules for working on an existing system
Iowa Administrative Code 641—Chapter 44 requires a state credential for radon mitigation work performed for hire, and as of July 1, 2026 Iowa's updated mitigation rules govern how systems are installed and modified. Practically, that means a repair that changes the system — new fan size, rerouted pipe, added suction point — is done under the same standards as a new installation, by a credentialed professional, and finished with a retest.

Repair or replace the whole system?
A failed fan on an otherwise sound system may be handled as a component repair when the replacement does not change system function or layout. A system that never brought levels down, was installed before current standards, or no longer matches the home after a renovation may need modification instead. That judgment call belongs to the credentialed professional on-site — which is why the request starts with what you observed, not with a preselected fix. If the "system" turns out to be a passive pipe with no fan, that is handled as a radon mitigation request rather than a repair.
