Plumbing is a skill that not everyone possesses, and certainly not the previous owners of this house.
Engineer Jansen noticed dripping in the garage. Dripping? It’s not raining, nor are there water tubes where it is dripping. A sewer pipe, yes. Which also should not be dripping. But it drips.
The sewer pipe there has a cap that you can unscrew in case there is a blockage. That was dripping. It should not be dripping. If it drips it means there is water behind the sewer cap. There should not be water behind the sewer cap. If there is water behind the cap it means there is a blockage further down the drain. Else there would be no water behind the cap, and it would not be dripping.
Simply unscrewing the cap seemed dangerous. As long as it drips there is water behind the cap, but unknown is how much. Also unknown is how clean. The cap did not budge. Not even with engineer Jansen’s biggest pliers. Off to the hardware store for even bigger pliers. And a backup sewer cap.
Even with the new pliers the cap did not budge. And it was still dripping.
First drain the drain, then. Drilled a hole in the cap. Yes, water. So the water level in the drain is above this. Not good.
Eventually the flow stopped. Still could not unscrew the cap. Stronger measures were taken, and after breaking off the edge of the cap it became clear that a MORON previous owner had used some glue. Fortunately not for the entire thread, but still sufficiently ansteystyle. (The cap has a rubber seal, you don’t need glue.)
Glue. You don't need glue, unless you want to infuriate engineer Jansen, which was successful.
There is a rubber seal there.
There is a rubber seal there.
Screwed on the new cap, flushed toilet. Still dripping. So, not fastened enough, and there indeed must be a blockage.
(New) cap.
And yes, the tube was a centimeter into the plaster on the wall. Removed some plaster.
Fortunately engineer Jansen possesses a 10 meter long Kärcher drain cleaning contraption. This was applied successfully. (Will not enter into details.)
Kärcher sewer cleaning hose.
Yes, Tex, it has been where you think it has been.
Another triumph for engineer Jansen, who is not fond of shitty problems like this, caused by sloppy work of a certain previous owner that never ceases to amaze him.
