Recently I was invited to an application for a mixer replacement. The client asked in advance if it would be possible to replace only the leaking cartridge, then only they will manage. And if the mixer falls apart when trying to unscrew the clamping nut, then we will replace it entirely.
At that time, we managed to get by with replacing the cartridge, link to the article at the end of this manual. But first, the landlord had to run to a plumbing store and exchange the wrong cartridge that he bought in advance for a better one. I taught him how to choose the right one and I will teach you.
Dismantling the mixer cartridge
But first you need to understand what to look at when choosing.
To do this, we divide it into its component parts by snapping off the latches.
In such a small case, there are so many details
Of this heap, only two ceramic plates are needed, and the secret is hidden in them. These plates are perfectly matched to each other and due to the forces of surface attraction, they are very strongly attracted. Like magnets.
The water flow is regulated by displacing these plates. Hot and cold water comes in small holes. And through the large one comes out mixed or only hot water or cold water.
When a large amount of liquid passes through such small holes, vortex flows are inevitably created. Which bring discomfort to users with their large noise effect. Especially when the trickle is small.
To prevent this from happening, stainless steel meshes are used in high-quality cartridges. When purchasing this part, see if it is there or not. If there is no noise during use is ensured! Also, don't go for nameless and cheap cartridges. If you have any comments, then I'm waiting for you in the comments.
Thumbs up the plumber! Link for an article on replacing the cartridge.
