Signs of a Blocked Drain

Most blockages gradually build up, but the effects nearly always appear to be sudden. If you had a blocked drain in Portsmouth for some time, you may have noticed this starting with a mildly putrid aroma drifting up from your drain. Then you might well see a common sign that the water in your kitchen sink takes ages to empty away! If this problem persists, eventually excess water can seep into your home unexpectedly. By this stage it’s time to call in a professional drainage company, No1PHD. Some signs of a blocked drain may include:

  • Unpleasant aroma
  • Water drains away slowly
  • Noises in the pipes or drain
  • Flooding in the drain
  • Waste water returning to the sink

The most important thing is, if you do see any signs that point to a blocked drain, contact us immediately as we offer same day callouts across the Portsmouth region.

Why Is Your Drain Blocked?

A very common cause of a blocked drain in your home is household waste. Your drain could be blocked through inappropriate waste sticking to the interior of the drainpipe. Most blockages quickly form when fat or grease are allowed to be flushed into the drainage system. To begin with, it floats on the surface of the water, but as it hardens it gets pushed to the side of the pipe. Once it has stuck fast, other debris such as hair, soap and toothpaste become entangled. The blockage, known as a fatberg solidifies like concrete and eventually forms an impassable obstruction.

Solution: Fatbergs are often broken up by powerful high-pressure water jetting or through the use of specialised drain cleaning tools fitted to a drain rod. Sections of the blockage are either vacuumed out or flushed away with a drain jetting technique perfected by our Portsmouth Drainage Team.

Drain Repairs and Renewals

There are many causes of drain blockages that can lead to repairs and new drain installations. A common issue for drain blockages in the Portsmouth area is Tree Root Ingress. This can cause severe leaks and can lead to either new drainage pipes being installed or having your drains relined. A tree’s root system radiates out on average to a distance of approximately twenty feet. Thin fibrous roots are inevitably drawn to moisture and can enter a drain or sewer pipe through the slightest fissure. The roots can quickly grow into a tangled obstruction that runs for several feet inside the pipe.

Solution: Our Portsmouth Tree Root Ingress experts won’t usually need to dig the roots out. They’ll remove them by cutting and winding them up with a specially designed augur or dissolving them to a pulp via the use of high-pressure water jetting equipment that our team use on a daily basis for unblocking drains.

Portsmouth CCTV Drain Surveys

A big advantage in using CCTV equipment for drain surveys is that you avoid the need of costly drain excavation, a process that would have been impossible a few years ago. Our No1PHD CCTV Drain Survey specialists can carry out a complete drain survey of your pipes and inspect your sewer network if needed quickly and efficiently with the minimum of disruption.

Thanks to this modern technology, we can inspect your drain in fine detail with the use of our waterproof CCTV drain camera equipment. The camera is attached to a flexible rod that is inserted into the drain to see exactly what type of blockage has developed. The camera can negotiate bends and relays highly detailed images to a monitor, allowing our professional drainage engineers to identify even the smallest cracks.

With this knowledge, we can now treat, clean or repair your drain pipes. We may use an advanced technique called Drain Relining, that creates a new inner layer inside the pipe. A strong resin bonds the waterproof lining to the pipe. Linings can even extend the life of the pipe for up to fifty years.

A CCTV Drain Survey of your sewer pipes or drainage system will ensure they are clean and your drains should remain unblocked for years to come.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
