Signs Replacement Is Needed
Replacement may be appropriate for cracked tanks, severe corrosion, failed nonreplaceable baffles, leaking shells, inadequate capacity, poor accessibility, or obsolete equipment that cannot be maintained reliably.
Repair Versus Replacement
A gasket, lid, tee, or serviceable baffle may be repairable. A compromised tank or fundamental sizing problem usually requires replacement. We inspect the whole system so a downstream clog is not mistaken for interceptor failure.
Replacement Process
The work may include:
- Pumping and isolating the existing unit
- Confirming fixture load and required capacity
- Coordinating plumbing permits and approvals
- Removing the old interceptor
- Preparing the location and piping
- Installing accessible inlet, outlet, vent, and covers
- Leak-testing and flow-testing the new unit
- Documenting initial maintenance recommendations
Frequently Asked Questions
Can a larger unit use the same piping?
Only when pipe size, elevation, venting, flow, and approved plans support it.
Will replacement correct a downstream sewer clog?
No. Connected piping must be inspected and cleaned separately when restricted.
