Blocked Drains - What to Do
Blocked Check out here are probably one of the most common problems in virtually any household. Whether it's 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 degree, but after a while something needs to be done to unblock it. And when you're in charge of a public building just like a school or then the drains are probably have to much more than just bleach.
The best little bit of advice when dealing with blocked drains is: don't try to unblock it yourself. Drainage services companies often find that if they are called out, they must cope with a much worse problem than it the client hadn't tampered with the drain themselves. Rather than 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 much more.
There are two principle methods used by drain clearance companies to clear blocked drains. The foremost is manual rodding. Manual rodding is pretty much what you believe that it is: utilizing a long metal rod to manually clear any debris blocking the drain. It is useful where there is not much space, but amateur attempts at achieving this are one of the biggest factors behind drain damage. It could sound like a spectacularly simple methodology, nonetheless it is a lot more involved than one might assume.
The second, far more exciting technique is that of ruthless jetting. Again, the moniker given the technique makes a conclusion almost redundant. However, it is worth noting that ruthless 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 space to properly utilise it, high pressure jetting is the most effective way of clearing blocked drains, since it also cleans residue from the medial side of the drain that could otherwise eventually build up into a blockage.
As such, high pressure jetting is really a technique that's sometimes used pre-emptively to prevent blockages, rather than waiting for the drain to get blocked at all. That is particularly ideal for large public buildings in which a blocked drain could easily spell disaster and lost working time.
Blocked drains is definitely an enormous headache. The best thing you can do in order to avoid further headaches down the road, is call a professional.
