Septic Tank Repairs

Not every problem means a new system. Cracked lids, broken pipes, damaged baffles and failed pumps or blowers can often be repaired. When the tank or drainage field has reached the end of its life, we'll say so plainly and explain the options.

Common repairs

The repairs we see most often

PipesCracked, blocked or root-damaged pipes between the house, the tank and the outlet.
Baffles and T-piecesBroken or missing fittings that let solids escape into the drainage field.
Lids and coversCracked, rotten or unsafe covers replaced so the tank is safe and accessible.
Pumps and blowersTreatment plant blowers, pumps, floats and alarms repaired or replaced.

Many problems start small: a slow drain, a smell near the cover, or wet ground over the pipe run. Fixing them early protects the drainage field, which is usually the most expensive part to replace.

Finding the fault

Finding the real cause first

We start by finding out what has actually failed. That usually means emptying the tank so it can be inspected, and sometimes a CCTV drain survey to see inside the pipes without digging. Guessing leads to repairs that don't last.

Repair or replace

When a repair isn't the answer

The general binding rules say a system must be repaired or replaced if it isn't in good working order. If the tank is structurally failing, a septic tank discharges straight to a watercourse, or the drainage field has given up, a repair only delays the inevitable. In those cases we'll explain the options, including septic tank replacement and upgrading to a treatment plant.

Cost

What affects the price

We don't publish standard prices, because two jobs rarely cost the same. These are the things that move the figure.

What has failedA cracked lid is a small job; a collapsed pipe isn't.
Where it isInside the tank, between house and tank, or in the field.
DiggingHow deep the problem is and what's on top of it.
PartsPumps, blowers and baffles vary by make and model.
Emptying firstMost tank repairs need the tank emptied beforehand.
ReinstatementPutting lawn, paving or driveway back as agreed.

Questions

Septic Tank Repairs questions

Can a cracked septic tank be repaired?

Sometimes. Small cracks in a concrete or brick tank can be sealed, and damaged fittings replaced. If the tank is breaking up or leaking into the ground, replacement is usually the better option.

Why does my septic tank smell?

Common causes are a full tank, a broken baffle, a poorly sealed cover or a blocked vent. Smells near the drainage field can mean it's failing. An inspection will show which.

Do you repair sewage treatment plants?

Yes. Failed blowers, pumps, floats and alarms are the most common treatment plant repairs. Tell us the make and model with your enquiry.

Do I need permission to repair a septic tank?

Like-for-like repairs normally don't need approval. Replacing the system or the drainage field normally needs Building Regulations approval, and we'll tell you if that applies.

Want a clear answer for your property?

Tell us what's happening and roughly where you are. No need to know what type of system you have.
