Repeat blockages indicate a structural cause: typically root ingress through a cracked joint, a partial collapse, a step in the line where solids catch, or a fat/grease build-up at a low point. Rodding and jetting clears the symptom; CCTV finds the cause. After the second blockage in 12 months, get a CCTV survey (€180–€340) — it pays for itself by directing repair money at the actual problem.

Drain lining inserts a resin-impregnated sleeve into the existing pipe and cures it in place, creating a new pipe inside the old one. It works for cracked or damaged pipes that are still structurally roughly intact. It's much cheaper than excavation — €1,200–€2,400 for 5m vs €1,500–€3,500+ for digging. It also avoids damage to driveways, paving, or trees. Suitable for around 70% of drain repair jobs; the rest still need digging.

Every 1–3 years depending on household size and tank capacity. A 4-person household with a 2500-litre tank typically empties annually. Smaller tanks or larger households need it more often. Skipping empties leads to overflow, percolation area damage, and eventual tank replacement which is far more expensive (€4,500–€9,500). Empties cost €180–€280 and should include a quick visual inspection of the tank condition.

You're responsible for drainage from the building to the property boundary (or to the connection chamber). Irish Water owns from there outwards into the public network. If a blockage or collapse is at the boundary or beyond, contact Irish Water free on 1800 278 278 and they'll investigate. If it's clearly your side (e.g. a manhole within your driveway), it's a private repair. CCTV survey can determine which side cleanly.

No. A working drain system is sealed by gulley traps and water seals so nothing should smell. Smells outdoors usually indicate a dry trap (water has evaporated from a gulley — pour a litre of water in to refill), a cracked or displaced pipe, or a broken vent stack. If running water doesn't fix it within 24 hours, investigate further. Persistent sewage smells need diagnostic visit, not just air freshener — they indicate ingress that gets worse.
