Our Services
Our certified technicians preform through inspections and testing of your backflow prevention devices to ensure they function correctly and protect your water supply from contamination. We comply with all state and local regulations, providing you with official certification upon successful completion. Timely testing helps prevent costly plumbing issues, keeps your property compliant, and safeguards health.
This service covers an on-site evaluation of your backflow device to identify issues and determine if a repair or rebuild is needed.
The $85 fee includes the inspection and minor adjustments if possible.
Repairs are not included and will be quoted separately on-site. If approved, we’ll apply the evaluation fee toward the final repair cost.
No work is done without your approval
Clear, up-front repair pricing provided after evaluation
Most repairs completed same day as assessment if approved
We do not perform any work without confirming pricing with you first- no surprises.
Whether you need to replace a failed backflow preventer or install a brand new one where none existed before, we provide on-site assessments to get the job done right.
We’ll evaluate your plumbing layout, confirm compliance with local water district regulations, and provide a detailed estimate for the correct device type and placement. This $125 fee includes travel, inspection, and a written quote- and is credited toward the installation if you proceed with the work.
