$80.00
Includes full device testing, certification, and electronic submission of results to the water district.
Late / Expedited Service Fee
+ $65.00
Added to the standard test price when a device is overdue or urgent testing is needed.
Past due notices and late testing fees
If you have received a past due test notice, 15-day warning, or water shut-off notice, additional fees may apply. When a device is overdue, we often need to:
- Re-route a technician immediately
- Prioritize same-day or next-day testing
- Submit test reports to the water district urgently
Because of this, a $65.00 Late / Expedited Service Fee will be added to the standard test price.
When late fees apply
A late or expedited fee may be charged if:
- Your test due date has already passed
- You received a 15-day notice
- You received a shut-off notice
- You request urgent same-day or next-day testing
- The district requires immediate submission to avoid penalties
We will always let you know ahead of time if the fee applies.

We will keep your water flowing, your devices compliant, and your stress level low, even when the water district is sending love letters with deadlines.
