Blocked drains 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.

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.
