Out with the old, in with the new! 👷‍♂️🚧

Our engineers attended site to investigate a section of pipework that had previously been repaired incorrectly. After excavating down to the affected area, we identified a poorly joined section causing restrictions within the line.

The defective section was removed and replaced with new pipework, securely connected using Fernco couplings. Once the repair was complete, the pipe was surrounded with shingle for protection before being carefully backfilled.

To ensure everything was functioning correctly, we carried out a CCTV survey following the repair, confirming the line was flowing freely and the repair had been completed to a high standard. ✅

🚨 Not all drain blockages are caused by wipes and grease…

Our engineers attended site to investigate a blocked drainage system affecting toilet and urinal facilities. Using high-pressure water jetting equipment, we worked upstream through the pipework to locate and clear the obstruction.

After sustained jetting operations, normal flow was successfully restored throughout the system. During the clearance process, we recovered large amounts of scale build-up, accumulated debris and, surprisingly, multiple staff ID cards! 👀

These materials had combined to create a significant restriction within the drainage system, leading to the blockage.

To ensure the issue was fully resolved, extensive flow testing was carried out by repeatedly flushing the affected toilet and introducing water into the urinal trough. All fixtures discharged correctly with no signs of backing up, confirming the blockage had been completely removed.

✅ Flow restored
✅ System tested
✅ Drainage left operating as intended

BLOCKED TOILET + RATS = ❌

We attended site to investigate and clear a blockage affecting two toilets. On arrival, both toilets were found to be blocked. We then located the external manhole outside the property and used high-pressure water jetting equipment to clear the obstruction from the drainage line.

Following clearance works, the system was flow tested and confirmed to be operating correctly with all waste flowing as intended💧

During inspection of the drainage chambers, multiple rat droppings were identified, indicating possible rodent activity within the drainage system.

We recommended the installation of rat blockers to the customer, preventing rodents from entering the pipework and causing future issues.

Did you know tree roots are one of the most common causes of recurring drain damage?🪾🌳

Attended site to ongoing drainage issues where a CCTV survey identified heavy root ingress within the pipework. Using specialist milling equipment, we removed the roots and restored flow through the run.

A follow-up CCTV inspection then revealed damage to the pipework caused by the roots forcing their way into the drain, allowing recommendations for repairs to be made before the issue becomes even worse.

Recurring blockage problems are often a sign of a bigger issue underground 👇

We attended site with two engineers following reports of a blocked gully within a light well area causing water to back up and drain poorly 🚧

After inspecting the system, we removed a buildup of waste from the gully pot and used high-pressure water to fully clear the blockage.

To ensure the drainage line was operating correctly, we carried out a full flow test using buckets of water and confirmed the run was flowing freely through to the manhole ✅

While onsite, staff also raised concerns regarding the sump pump system. We inspected and tested the unit, confirming it was operating correctly and in full working order.

All work completed successfully 👍
