There are a lot of various articles on the network about reliable fastening, but there is not a single article considering the most unreliable ways of fastening sinks. You also need to know this, in order to avoid mistakes, to be able to correctly install the sink yourself, or to monitor the work of a hired plumber.

Incorrect installation

Unskilled and novice plumbers often do not pay attention to some little things. In the practice of plumbers, there are often such methods of installing products that give a negative result. This happens for several reasons:

• Marriage of the manufacturer;
• Roughnesses of the wall in the place of fixture;
• Hollow wall;
• Low qualification of the installer.

Unreliable mounting, have wall mounted sinks. They are fixed at two points to the wall. Having a large weight, such a product creates a large load on the mounts. The installer needs to be especially attentive to the attachment points of such sinks.

Manufacturer's marriage

This, although infrequently, occurs. The part with the fixing eyes of the sink has irregularities, which is why it does not fit snugly on the fixing surface. When fixing such a product, excessive force is created in the attachment points, which eventually leads to loosening and failure of the fasteners.

Irregularities in the wall

It leads to the same consequences as the manufacturer’s marriage. The surfaces of the product and the walls, at the point of contact, should be perfectly even. To check the wall for waves, a deliberately flat object, for example a small board, will help. Putting the board against the wall, we look to see if there is a gap in the place of contact, if there is, the wall needs to be aligned.

Hollow wall

Frame houses are stacked from hollow panels. The void is filled with insulation. It is generally impossible to fix a sink to such walls. But in practice, inexperienced professionals often try to do it.

Low qualified installer

Incorrectly selected tool, and the fastener system will be broken. Drilling a well under factory fasteners should be carried out strictly by the diameter of the drill specified in the instructions. If there is no such information, measure the diameter of the plastic filler of the well with a vernier caliper and pick up a drill 1-2 mm less.

Installation Check

After installing the sink, it's a good idea to check the quality of work. Try to swing the product in different planes, but without applying strong force. There should not be any backlash. Any backlash will progress rapidly, this may result in a fall, damage to the sink. Demand to redo the work.
