What we handle

Common repair & maintenance issues

Nine symptoms account for almost every repair job. We triage by severity — emergency overflows jump the queue.

Emergency

Overflow / standing sewage

Sewage on the surface near the tank, toilet backing up, foul water in inspection chambers. Immediate tanker dispatch.

Urgent

Bad smells outside the house

Persistent sewage smell in garden, drains or around the tank. Usually venting, levels, partial blockage or a cracked lid seal.

Medium

Slow drainage & gurgling

Sinks and baths draining slowly, gurgling sounds from toilets or plugholes. Early sign of over-full tank or partial blockage.

Medium

Blocked pipes

Inlet, outlet or soakaway blocked. Jetting, CCTV inspection and clearance — usually same or next day.

Routine

Annual emptying / desludging

Routine tanker visit to remove accumulated solids. Typical frequency: every 12–24 months depending on use.

Routine

Annual service (treatment plants)

Required for sewage treatment plants. Air blower check, desludge, electrics & alarm test, service report.

Medium

Drainage field failure

Soakaway saturated or collapsed — visible ponding, boggy grass, slow empty after desludge. Diagnosis then options.

Medium

Pump & alarm faults

Pumped drainage or treatment plant alarm sounding. Electrical fault, pump burnout or high-level alarm — needs same-week attention.

Routine

Lid / cover replacement

Broken, corroded or non-child-safe covers replaced. Often combined with a maintenance visit.

Repairs FAQs

The questions we hear most

How fast can someone attend an active overflow?
Typically 2–6 hours from the call, including out-of-hours. We route emergency leads immediately to the nearest available partner — they don't queue behind routine work. If you're seeing sewage on the surface, call first rather than using the form.
How often should I empty my septic tank?
Most UK domestic septic tanks need emptying every 12–24 months. Treatment plants typically every 12 months or per manufacturer's schedule. Heavy use (large family, home working, frequent guests) pushes frequency toward the shorter end. If in doubt, book a check-lift.
Do you accept out-of-hours calls?
Yes — our emergency dispatch line (0800 123 4567) runs 24/7, 365 days a year. Out-of-hours attendance is typically a £50–£150 surcharge on the base call-out, confirmed when we dispatch.
What if the blockage turns out to be something else?
Our engineers diagnose before charging for remediation. If a call booked as a "blockage" turns out to be a mains-drainage issue, a tenant-side issue or not septic-related at all, we'll tell you up front and you pay only for the diagnostic visit.
Will you dispose of the waste legally?
Yes. Every tanker we match holds a valid waste-carrier licence and a consignment note is provided after each emptying visit. Waste is taken to licensed wastewater treatment works only — never land-spread or illegally disposed.
Do I need to be home during the visit?
Preferred but not essential. If the tank is accessible without entering the house and you've confirmed access arrangements at booking, the job can proceed without you on site. Photo evidence and a completion certificate are sent afterward.
What if my system just needs replacing?
If a repair visit reveals an end-of-life tank or failed drainage field, the engineer will say so and you'll receive a separate replacement quote — no pressure. See our replacement page for what's involved.
