Blocked Drains - What things to Do
Blocked drains are probably one of the most common problems in virtually any household. Be it a sink, basin or toilet, drains get blocked each day and cause a large amount of headaches. Pouring bleach down the sink works to a certain extent, but after a few years something must be done to unblock it. And when you're responsible for a public building such as a school or then the drains are probably have to a whole lot more than just bleach.
The best piece of advice when coping with blocked drains is: don't try to unblock it yourself. Drainage services companies often discover that if they are called out, they need to cope with a much worse problem than it the client hadn't tampered with the drain themselves. Instead of just coping with the blocked drain, they suddenly find themselves met with a blocked and damaged drain, creating much more work. This is simply not only frustrating for the drain clearance company, but eventually ends up costing the client a lot more.
There are two principle methods utilized by drain clearance companies to clear blocked drains. The foremost is manual rodding. Manual rodding is pretty much what you believe that it is: using a long metal rod to manually clear any debris blocking the drain. It is useful where there isn't much space, but amateur attempts at doing this are one of the biggest causes of drain damage. It could appear to be a spectacularly simple methodology, but it is a lot more involved than one might assume.
The second, far more exciting technique is that of high pressure jetting. Again, the moniker given the technique makes a conclusion almost redundant. However, it is worth noting that high pressure water jetting is indeed effective that it is also used for a great many other applications, such as cleaning gum of pavements and car parks. If you find enough room to properly utilise it, high pressure jetting is the most effective way of clearing blocked drains, as it also cleans residue from the side of the drain that could otherwise eventually build up into a blockage.
As such, ruthless jetting is really a technique that is sometimes used pre-emptively to prevent blockages, rather than looking forward to the drain to get blocked at all.

Blocked drains can be an enormous headache. The best thing you can do in order to avoid further headaches later on, is call a specialist.
