Short answer

Editor: It depends on where the tank discharges, its condition and the rules for your nation. Point to the checker. Official sources only.

When the rules may mean an upgrade or replacement

Editor: Official conditions per nation, each with a source line.

When it's about condition, not the rules

Editor: Signs to get a professional to look at, from official or maker guidance. Never suggest opening the tank. Link to septic-tank-problems when it exists.

Upgrade or replace?

Editor: Conversion units and replacement routes, only as the official rules describe them. Link to C28 later.

Costs

Editor: No figures unless a named official or published source states them with a date. Point to the replacement cost planner (C6, batch 2).

Questions to ask before you pay

Editor: The installer box below covers this; add any job-specific ones.

FAQs

Editor: Four to six FAQs, official sources only.
