In theory, the steps involved in unblocking a drain when you know what the problem is...is quite straight forward. In practice, a lot can go wrong. Why is that? Because of the chemicals you will likely be using to unblock the drain. The average person isn't used to using them at all. Many don't use gloves or eye protection and find themselves in A+E with burns / swollen eyes or both. The chemicals involved with these particular types of blockages are very caustic and require extra-special care in handling them. Even if you use them appropriately, then you still have to keep them WELL out of reach of children, preferably in a locked cupboard with the key well away from children.
Then of course, you have to diagnose the problem in the first place! That involves a long check list if you're going to do it properly.
Do you see where I'm going with this? Yes, I think you do. It's wise to call professionals to help your blocked drain problem. They have the experience, training and tools to diagnose and fix your problem. They can also advise you on how to KEEP your drain UNBLOCKED for the future. A good drainage expert will save you money in the long run with this kind of advice. Even if the problems are caused by things you can't prevent, hiring the same professional can be a good move as they will be familiar with your drainage system and if it's a repeating issue, they can quickly apply a fix on subsequent returns to your property.
