Stop leaves blocking your drains

Monday, November 28th, 2011

Autumn is a busy time for drain cleaning experts. They normally get a lot more calls at this time of year due to leaf debris blocking garden drains. If you live in a home which is surrounded by trees or woodland, you’ll probably already know the problems that leaf litter can cause to your drainage system. When the leaves fall from the trees they usually end up being blown around the garden and find their way into the gutters and drain gullies around your home. Because of this it is really important to make sure that you embark on a regimen of home maintenance at this time of year to stop drainage problems before they happen. Around late autumn you should check your gutters for debris and remove any leaves you find. You should then check all the drain gullies around the home and remove any leaves which are collected here also. It’s just about impossible to stop any leaves from entering the drainage system, but if you fit drain covers to all your drains, the leaves will not be able to accumulate. And if you make sure your gutters are free from leaves, you should be able to reduce drain blockage incidents significantly.

Fixing a blocked sink

Saturday, November 26th, 2011

At some point in your life you’ll have to contend with a blocked sink or blocked bath tub. Blocked sinks are a common occurrence faced by thousands of households every year. However, you needn’t panic if you have a blocked sink, as removing the blockage is normally quite simple. When your sink is blocked you might notice that the water drains away much slower than usual. If the sink is completely blocked, the water won’t drain away at all and you might have to manually remove some of the accumulated water before you can tackle the blockage. Some sinks have a detachable ‘U’ bend pipe which sits just underneath the sink. It’s common for this section of pipe to accumulate food debris and solidified fats. With a bucket placed under this section of pipe it’s easy to unscrew the pipe from the adjoining sections so the waste matter in the pipe can be disposed of in the general waste. If you don’t fancy your plumbing skills, you can try a plunger or use a rotating drain snake, which is a flexible rod like device which you can insert down the plughole to try to shift the clog. If all else fails and the sink blockage is still proving difficult to move, a quick call to your drainage experts in London should get the job done.

Trenchless technology used in Tun Bridge

Thursday, November 24th, 2011

Thames Water has started work on the replacement of a sewage pipe in Mortimer which has burst a number of times over the last few years. The pipe in question, in Tun Bridge, has experienced problems four times over the last five years and will be repaired using the latest ‘no-dig’ technology. The existing pipe will be repaired using a 300 metre length of pipe liner, which should put an end to the recent problems. The capital delivery manager for Thames Water stated:

"There is no place for sewer flooding, and we’re all too aware of the inconvenience caused when a pipe, such as this one, bursts. The aim of this project is to put an end to all that. "We will lay the new pipe using ‘no dig’ technology, which avoids having to dig an open trench along the entire stretch of the road. The majority of our work will be carried out in nearby fields, although there will be some work on The Street. "We're in a hurry to complete this essential work before Christmas to give people peace of mind by preventing future bursts."
No road closures will have to be made while the works are carried out and Thames Water hopes the works will be completed before the busy Christmas period.

No dig technology benefits

Tuesday, November 22nd, 2011

There are many reasons why drains can become blocked, but one problem that drainage companies face on a regular basis is root infiltration into the drainage system. Pipes can become blocked by roots when they find their way into the drainage system. They do this by finding tiny cracks in pipes and by working their way though corroded or damaged sections where pipes join together. Once the roots have entered the drainage system they quickly multiply due to the abundant source of water and can soon block the passage of waste water completely. Drain maintenance engineers can get rid of the roots that may have entered your drainage network. They use a spinning root cutter, which is the same diameter as the pipe, to cut through any roots and associated debris. When the roots have been cut back, the pipe damage may be revealed. However, instead of a section of pipe having to be replaced, most drainage companies now use ‘no dig’ technology to repair the pipe. One of the most common types of no dig repairs involves inserting a resin impregnated liner into the pipe and positioning it across the area of damage. When the liner sets, the pipe is completely repaired and its waste water carrying capacity is restored.

Problems with scaled pipes in London

Wednesday, November 16th, 2011

Living in a hard water area can come with its own inherent problems. It’s not uncommon to find that drainage pipes can build up a layer of this scale if left untreated, and in the worst case scenarios the pipes can become blocked completely. You may have noticed that water is being carried away more slowly when you pull the plug out of the sink, or you might be the victim of recurrent drain blockages. Both can be put down to scaled pipes. It’s not too difficult to remove this scale from the pipes, but it’s always a good idea to get a professional firm to descale your pipes for you. London drain cleaners can remove the scale from the drainage pipes which leave your home by using a specialist descaling device. The descaling machine cuts the scale from the internal diameter of the pipe and restores it to its original dimensions. It also removes any rough edges from the insides of the pipe so that debris will not be able to get stuck and hence the chances of subsequent blockages will be reduced.

Drainage pipe liner repairs

Monday, November 14th, 2011

If a drainage pipe was found to be damaged, it used to be the case that the pipe would need to be excavated and replaced. This would not only take a great deal of time, it would also cause a great deal of inconvenience to the area directly around the drain. However, excavation is no longer needed, thanks to the introduction of drain lining and trenchless technology. Drains can be damaged by a number of things, but mostly it’s just the effects of time which cause damage to the integrity of the pipe. Other things which can damage drains include root infiltration, subsidence, pressure damage and chemical damage. Many drainage companies in London now offer a service where instead of excavating a damaged pipe they can simply conduct a liner repair. In this process a resin coated liner is inserted into the damaged section of pipe and then inflated so it adheres to the inner pipe surface. This liner repair, when set, will make the pipe as good as new and able to be used for as long as the pipe is in use. Pipe liner repairs are a great way to repair a broken or damaged pipe without the need for excavation.

New Thames Tunnel consultation gets underway

Saturday, November 12th, 2011

The fourteen week consultation on London’s super sewer, the Thames Tunnel, started on the fourth of November. The new sewer is needed to tackle the growing problem of sewage entering the River Thames at times of heavy rainfall, when the Victorian sewer system simply can’t cope. Thames Water have now detailed a list of updated sewer construction sites, which reflects on the feedback obtained from the first consultation process which ended in January. The new proposed main tunnel drive sites are now: • Carnwath Road Riverside in Fulham • Chambers Wharf in Bermondsey • Kirtling Street in Battersea In addition to the main drive sites there will be further tunnel reception sites and seventeen other smaller construction sites needed to fulfil the tunnel plans. The head of London Tideway Tunnels at Thames Water, Phil Stride, stated:

"We have been working hard to refine our original plans, where possible, in the light of the concerns people have raised with us. This has resulted in some significant changes, also reflecting our absolute determination to balance overall disruption with the equally important need to ensure that the price tag remains affordable for our customers. "There are no easy choices when it comes to selecting construction sites, but our focus during this latest phase of consultation will be to work with communities around our revised list of preferred sites to ensure we understand and address their concerns effectively. It is particularly important that we listen to local people’s views on what individual sites should look and feel like after construction work has finished."
