What can cause a gutter leak and how to fix it?

The leak is likely to be caused by a leak at the splice-to-groove connection as a result of the expansion of these elements or damage to the gasket. Since the gutters are subject to significant temperature changes, they undergo thermal movements - they contract and expand cyclically. Plastic gutters have a particularly large variation in length, which helps to smooth the seams. This phenomenon is facilitated by the uneven heating of the drainage system.

For example, part of the length of the gutter is permanently shaded, while the other part is exposed to intense solar radiation. The problem is caused by too low connection rates. In the described situation, in addition to printing, rigid mounting in the handles, without the possibility of sliding, can contribute. This is probably due to the fact that the old hooks remained, which, even with the same nominal diameters of the gutters, may differ slightly from different manufacturers. As a result, one of the chute sections will slide out of the connector as the material contracts and does not return to its original position after expansion due to heat. The repair method can be selected after checking the condition of the gutters and their connections. Repairing the leak will improve the leaking joint by moving the connector, possibly adjusting the gutter position and replacing the gasket.

It is also possible to avoid cracking or breaking the hitch resulting in insufficient seal pressure and such an element must be replaced. Ultimately, consideration must be given to replacing the gutter with the original gutter for this system if subsequent leaks appear after 1-2 years of use. Replacing them will not be a problem if they are attached to the front panel or can be installed. However, if the brackets were attached under the roof covering, it would have to be partially disassembled in the eaves area.
