Blocked drains are one of the most common problems in any household. Be it a sink, basin or toilet, drains get blocked every day and cause a large amount of headaches. Pouring bleach down the sink works to a certain extent, but after a few years something should be done to unblock it. And when you're in charge of a public building such as a school or then the drains are probably going to need much more than just bleach.
The best piece of advice when coping with blocked drains is: don't try and unblock it yourself. Drainage services companies often discover that when 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 dealing with the blocked drain, they suddenly end up met with a blocked and damaged drain, creating a lot 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 first is manual rodding. https://www.tcmdraincare.co.uk/ is just about what you think it is: utilizing 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 doing this are one of the primary causes of drain damage. It may appear to be 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 really is worth noting that ruthless water jetting is so effective that it's also used for a great many other applications, such as for example cleaning gum of pavements and car parks. When there is enough room to properly utilise it, high pressure jetting is the most effective way of clearing blocked drains, since it also cleans residue from the side of the drain that could otherwise eventually build-up into a blockage.
As such, ruthless jetting is a technique that's sometimes used pre-emptively to avoid blockages, rather than waiting for the drain to obtain blocked at all. This is particularly useful for large public buildings where a blocked drain could easily spell disaster and lost working time.
