Drain blockage.

"Fixed it without any issues and was very friendly and hard working."

Clearing very blocked drain

"I could not believe the amazing service. I phoned just before lunch, and immediately received a phone call to confirm they would carry out the job between 3pm/5pm THAT DAY! Just the one man carried out the job , no time wasting. He was polite, and super efficient."

Drain cleared.

"Very good. But there was no mention of "Happy Drains" on the side of the van — it was a subcontractor who carried it out, and it looks like Happy Drains might well not have any actual drain clearance teams of their own. I would be better off going direct to the subcontractor for any future work as it would be cheaper."

It’s not always obvious who’s responsible for a particular section of London drain or sewer pipe, but here’s our quick guide to establishing who’s responsible for London drains when they get blocked or need repair.

Who’s responsible for blocked London drains?

If the drain serves exclusively your property and the blockage in the drain is with your property boundary then that is the owner’s responsibility. If it’s shared or beyond the property boundary then it’s probably the responsibility of Thames or Southern Water.  Our diagram below makes this much clearer. If in doubt, please give us a call for advice.

Diagnosing blocked London drains

It’s not always obvious if a drain is blocked or why it got blocked in the first place, but here’s a few pointers to set you in the right direction.

How do you know if a drain is blocked?

An obvious indication that a London drain is blocked is a slow running sink or toilet. Sometimes the toilet over fills or the water even appears to have been sucked out the pan. That is a vacuum caused by a blocked drain downstream of the toilet. Water seepage in the yard or garden is also a likely indication.

Why do drains get blocked?

Never put fats down a London drain! Over time, this will always result in drain blockages. Likewise, paper towels, wet wipes & sanitary products should not be flushed down as they don’t breakdown and result in blockages. Too much paper and cat litter can also be the cause of blocked drains. Remember it’s a toilet not a bin!

Why does my drain keep getting blocked?

There are many factors, but something you need to consider first is professional London drain cleaning. This is because DIY solutions often just don’t work longer term. There could be underlying problems and further investigations are strongly recommended when experiencing regular drain blockages. Cracked or misaligned drains, root damage or accidental damage are common London drain problems that a professional company such as Happy Drains can help you with.

Can a blocked drain cause damp?

No, is the simple answer for a drain in good condition, but broken or cracked drains can cause damp. Drains are designed to be watertight. The water would seep out of a crack or failed joint to cause damp or numerous consequential damage issues. A flooded and overflowing drain will cause damp issues if left unresolved. Our CCTV survey can find all of these problems.

Repairing broken or damaged London drains

Sometimes London drains become blocked or leak due to damage which can result from many causes.

How do you repair a broken London drain?

The site condition would dictate the requirements, but the two main methods are either excavation or no dig technology such as a sleeve inserted within the drain. It depends which option is practical and cost effective based on appropriate investigations. A drainage professional would determine that after visiting site and undertaking a London CCTV drain survey.

How do you clear a blocked sink U-bend?

The U-shaped pipe beneath a sink is designed to use water as a seal to stop smells and drainage gasses from drifting back up and out into your home. The shape of the trap also catches heavy debris and if this is allowed to build up it’ll result in blockages. It’s easy to clear it, and a lot cheaper than calling out a London drain company:

    1. Empty the sink with a bucket, take the water and pour it down the WC.
    2. Put the bucket in place under the trap.
    3. Loosen the trap by undoing the plastic screw coupler, remove it and let the water out into the bucket.
    4. Take a metal coat hanger and run it through the pipe and the trap to dislodge any debris.
  1. Replace.

Unblocking a London drain with a plunger

Clearing a blocked drain with a plungerWe recommend every London home should have one. The plunger one of the best home DIY tools for unblocking sinks and toilets. The toilet plunger is the bigger version. A sink plunger can be small or large, the bigger the plunger creates more plunge power – the magic ingredient.

For sinks, remove the metal strainer in the drain prior to plunging. The secret lies in creating a good seal between the plunger and sink or WC. Get the plunger in place and then get to work, with fast, sharp pumping motions. For toilets, the rubber disc must not be smaller than the U-bend. This is vital to successfully unblock a London toilet. Simply push the plunger up and down fast and hey presto.

Unblock a London drain with a hand driven snake

This simply works by pushing and twisting a thin snaking steel wire into the small-bore pipe work that serves sinks, showers and London baths. The cable is twisted and propelled forward by hand and when it hits the obstruction it dislodges the debris to restore the flow. This task takes a little time and perseverance, you will have to remove the trap before attempting to clear and drain using this technique (see our guide above) but make sure you place a bucket under the trap to catch the water.

How do you unclog a London drain without a snake?

Yes, the use of boiling hot water is often effective, and chemical drain cleaner can be also used. Kinetic force can also be effective, such as a water ram or a simple plunger. This uses the transfer of energy to push the blockage along the pipe. This is effective in a sealed system where there are no connections, so the force is focused forward to dislodge the blockage.

Using soda or cola to unblock a drain

You probably have a bottle or two around your home and it’s perfect for unblocking drains. To be effective, your favourite bottle of fizzy pop should be at room temperature and should be full fat, not the diet or lite types. You may recall from science lessons at school what happens to a tooth if you leave in a fizzy drink. The same corrosive quality of your favourite cola does the same to a blockage if poured down the drain and left for an hour or two. Give this method a go. It’s a little eco-friendlier compared to a dangerous chemical drain cleaner.

London CCTV Drain Surveys

London drain CCTV priceSometimes the only way to get to the bottom of a London drain problem is to go inside the pipe with a camera and for that, Happy Drains are the no.1 choice of partner to provide such specialist services.

What is a London CCTV drain survey?

A London CCTV drain survey is a detailed examination of your drainage system. The survey will determine the structural condition and the serviceability of the drainpipe. During the inspection we will note all defects and issues to allow you to understand how the drain works and its condition. We use high-tech CCTV cameras that are propelled through the drain to identify and report any issues that might be present.

What is a CCTV drain survey report?

Any professional drain survey should come complete with a written technical report using industry standard software. This details information such as the date, manhole numbers from & to, size of pipe, pipe material, shape, direction, distance (m), lengths, remarks and pictures of relevant observation.

All of this information should be evidenced via a video file for referencing and quality assurance purposes.
