Blocked drains are probably one of the most common problems in any household. Whether it's a sink, basin or toilet, drains get blocked every day and cause a lot of headaches. Pouring bleach down the sink works to a certain degree, but after a few years something should be done to unblock it. And when you're responsible for a public building just like a school or then the drains are probably have to a whole lot more than just bleach.
The best little bit of advice when dealing with blocked drains is: don't try and unblock it yourself. Drainage services companies often discover that when they are called out, they have to 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 end up confronted with a blocked and damaged drain, creating a lot more work. This is simply not only frustrating for the drain clearance company, but ends up costing the client a lot more.
There are two principle methods used by drain clearance companies to clear blocked drains. The first is manual rodding. Manual rodding is virtually what you believe that it is: using a long metal rod to manually clear any debris blocking the drain. It really is useful where there is not much space, but amateur attempts at achieving this are one of the primary causes of drain damage. It could sound like a spectacularly simple methodology, nonetheless it will be a lot more involved than one might assume.
The second, far more exciting technique is that of ruthless jetting. Again, Drain Unblocking Bradford given the technique makes a conclusion almost redundant. However, it really is worth noting that ruthless water jetting is so effective that it's also used for a number of other applications, such as for example cleaning gum of pavements and car parks. When there is enough space 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 which could otherwise eventually build-up into a blockage.
As such, ruthless jetting is a technique that is sometimes used pre-emptively to prevent blockages, rather than looking forward to the drain to get blocked at all. That is particularly useful for large public buildings in which a blocked drain could easily spell disaster and lost working time.
Blocked drains can be an enormous headache. The great thing you can do to avoid further headaches in the future, is call a professional.
