Why a Schedule Matters More for Aerobic Systems
Aerobic systems have mechanical and electrical components that wear over time, which is why Texas requires a maintenance contract for most aerobic systems, particularly during the first two years of operation. Staying on schedule catches small issues — a worn aerator, a low disinfectant supply — before they become alarms or failures.
Building a Simple Routine
The easiest way to stay on schedule is a maintenance plan that handles scheduling automatically rather than relying on memory. Whichever system you have, treating maintenance as routine — not something you do after a problem appears — is the single biggest factor in avoiding costly repairs.
Key Takeaways
- Conventional systems need pumping every 3-5 years and an annual visual check.
- Aerobic systems need professional inspection at least twice a year, per Texas requirements.
- A maintenance plan removes the guesswork and keeps small issues from becoming expensive ones.
Frequently Asked Questions
Yes, particularly during the first two years after installation, and it's strongly recommended to continue afterward.
Basic visual checks are fine, but professional inspection and component servicing should be handled by a licensed technician.
Small issues go unnoticed longer, increasing the risk of a costly failure or emergency repair.
