Ventilation in the bathroom of a private house. My first experience with DIY installation.

Ventilation in the bathroom and toilet is an important point that should not be forgotten when building a private house.

After all, its absence leads to a number of sad consequences, ranging from stuffiness in the room and ending with the formation of mold on the walls and ceiling.

It takes a lot of effort and money to fight the fungus, so it's better to think about installing ventilation in your house even at the construction stage.

So my friend thought about this, but he did not have extra funds to contact professionals on this issue. Asked for help from me.

What came out of this, we will consider below.

Before this incident, I did not have to install ventilation in a private house. But he knew the basic principles of installation, so he agreed.

The bathroom and toilet in this house are separate, but we decided to install one ventilation system for them.

To begin with, we decided on the place of laying the air duct and, using a perforator, with a drill with a diameter of 16 mm at an interval of about 5 mm, drilled holes in the wall.

Then, at high speeds, he connected the holes in a circle, grinding off aerated concrete.

Then he removed the excess parts of aerated concrete hollowed out in a circle from the wall.

I had to make two holes: one in the wall between the bathroom and the toilet, and the other through to the street.

The next stage of work, which was done, was to measure the required length of the duct and draw up an approximate plan of the connection.

The ducts were connected with aluminum tape and fixed to the ceiling with punched tape.

At the outlet of the tee, I installed a non-return valve in the bathroom and toilet.

And then a forced draft fan.

To prevent vibration, in the place where the air ducts are attached to the ceiling, the space was filled with polyurethane foam.

He also filled the space between the duct and the wall with foam.

I installed a check valve on the street side.
