Drain Repair Techniques
there was a time when your only option when it came to drain repair was an excavation, however the development of drain camera inspection systems over the years has led to the plethora of no-dig solutions.
The drain repair method that suits your system will depend on the actual cause of the damage, the severity of the damage and the available access into the system, there are scenarios where a system can be repaired without any disruption at all but in reality we tend to use a combination of excavation and no-dig repairs particularly on domestic systems.
A detailed camera inspection is usually the first step to assess the condition of the system and the extent of any damage, from this your contractor will decide which of the following methods can be used.
Drain Excavation and Repair
It pains me to say this but there are occasions when the only answer is to excavate and repair a broken drain, if there is a complete collapse on the vitrified clay drain that a drain jetter can not shift then its time to get the shovels out and dig. Other scenarios such as severe displacement of drain joints or severe fractures can put a system beyond a drain lining method as the repair moulds itself to the host pipe.
drain linersDrain Lining, Drain Re-Lining, Cipp Lining
There are several methods for lining drains but you are basically putting a fibre glass pipe inside the existing drain or sewer, as mentioned above most of these system mould themselves to the host pipe so any degree of deformity in the host pipe has to be assessed.This is a great way to repair root damaged, fractured or leaking pipe work where nominal displacement or movement has occurred
Drain Patch Liners, Spot Repairs or Local Patch Repairs
These are small sections of drain liner that can be installed part way down a system to target specific defects such as a single fracture, root damaged or stepped joint, they also enable you to repair defects between live connections without having to re-open the connection with a robotic cutter afterwards. The inflation method on these repairs differs from standard drain liners so this repair can in affect iron out a step joint against the flow of a system to some degree.

We attended a job today where the customer had tried to clear the blocked drains themselves using a drain cleaning chemical and a plunger, the plunger caused the drain acid to splash into her husbands eye putting him in hospital with a very serious eye injury. So we have put together a few tips to prevent further accidents.
Chemical drain cleaners like caustic soda and ‘ one shot ‘ work by eating away at the blockage. Care should be taken with their use as they can blind and burn skin. If correctly used, these products are extremely effective, particularly for blockages deeper in the drain.
Either liquid or crystal in form, chemical drain cleaners are generally poured into the drain opening and allowed to sit for a period of time. During this period the sink, bath etc. must not be used. When using a chemical drain cleaner always follow the manufacturer’s directions.
Never mix one type of drain cleaner with another.
Never mix drain cleaners with other cleaning products as toxic fumes may be produced.
Always ensure good ventilation when using chemical drain cleaners.
Don’t allow drain cleaners to remain in contact with porcelain or enamel surfaces for any length of time as the caustic nature of the cleaner will degrade the finish.
Never us a plunger on a drain which contains drain cleaner – you run the risk of splash-back and severe chemical burns.
If you are not completely confident in your ability to use these products, then don’t attempt it,
You can always give us a call 24 hours a day for some free advise.

Efficient drainage is never a problem until it stops working. All drainage systems need cleaning at some point in time. Scale, silt, fat and grease inevitably accumulate, reducing capacity and flow, and can even cause a total blockage.
High pressure water jetting is an effective cleaning technique for use in drains, sewers and pipework systems. It can be used to remove relatively soft silt or hard substances such as scale or cement.
Blockages in drains, sewers and stack pipes can be cleaned using this highly effective technique. Powerful jets of water developing pressures of up to 4000psi strip deposits from pipe walls, flush out debris and restore free-flowing conditions.
High pressure water jetting can also be used to ensure that process pipework is clean and clear of obstructions. Naturally, when scale and residue build up, manufacturing efficiency declines. Boiler scale, polymer resins, carbon deposits, milk scale and even concrete can be prised away with relative ease.
Most businesses don’t give their drains a second thought – they’re very much out of sight and out of mind. But when there’s a problem like a blockage or poor drainage it can cause flooding and costly disruption.
If left un-repaired a blockage, which would cost just Tens of pounds to repair, could lead to flooding costing a few thousand pounds worth of damage and disruption. In the worst case scenario this could lead to the drain collapsing, costing tens or hundreds of thousands of pounds to repair.
Clearflow Drains offer a range of services from CCTV drain surveys to jetting and rodding to remove blockages.
How we do it

Remove blockages: We use a variety of methods, including jetting and cleaning, root cutting and rodding.
Maintenance: Regular cleaning of your private drains can prevent blockages, helping to avoid costly repairs and the associated disruption.
