FAQs
How can I tell if my main sewer line is clogged or damaged?
Common signs include multiple fixtures backing up at the same time (e.g., toilet and bath), gurgling noises from drains, foul odours coming from inspection chambers, slow drainage even after plunging, and unexplained wet patches in the garden. In older Manchester properties with clay or pitch-fibre pipework, root intrusion and pipe collapse are frequent causes. If you notice any of these symptoms, it’s best to arrange a professional inspection before the problem escalates.
What methods do you use to diagnose main line issues?
We typically start with a CCTV drain survey, inserting a high-definition camera through an access point to view the entire run of pipe. This reveals blockages, cracks, root ingress, or misaligned joints. If we suspect a partial collapse, we may supplement the CCTV with sonar pipe tracing to map the exact pipe route. For water supply mains, we can carry out acoustic leak detection and pressure testing. All findings are captured in a digital report with video clips that you receive the same day.
Do I need permits or permission in Manchester for main line repairs?
For private drains within your boundary, no council permit is needed, but work must comply with Part H of UK Building Regulations. If the repair involves the public sewer (usually any shared pipe or a pipe outside your property boundary), United Utilities must be notified and may require an application. Street works that involve digging up a pavement or road require a Section 50 licence from Manchester City Council. We handle all permit applications and traffic management so you stay fully compliant.
How much does a main line repair or replacement typically cost?
Prices vary with pipe diameter, length, depth, and ease of access. A straightforward high-pressure jetting and root removal can start at £150–£250. Patch lining a localised crack might range from £350–£600. Full excavation and replacement of a 6-metre clay sewer at 1.5 m depth typically costs £2,000–£3,500. Trenchless pipe bursting or relining can be more cost-effective for longer runs, from about £80 per metre. We provide a fixed quotation after the initial survey so there are no surprises.
How long will it take to repair my main sewer line?
Minor jetting or rodding jobs are usually completed in under two hours. Installing a cured-in-place pipe (CIPP) patch liner on a small section takes about half a day, including curing time. A full excavation and pipe replacement can run from one to three days depending on depth and reinstatement requirements. If a permit to work on the highway is needed, there may be a 5–10-day notice period before work can start; we’ll advise you of the schedule at the survey stage.
What can I do to prevent future main line problems?
1) Avoid flushing wipes, sanitary products, or excessive kitchen grease—these are top causes of blockages. 2) Fit drain guards on kitchen sinks to catch food debris. 3) Arrange a CCTV inspection every 3–5 years if you live in an older property with clay or pitch-fibre pipework. 4) Keep trees and large shrubs at least three metres from underground sewer lines to discourage root ingress. 5) Consider a proactive chemical root treatment every 12–18 months if you’ve had roots before. Preventive maintenance is far less expensive than emergency repairs.
