In the past, I always found that the pressure of the wall-hung pot building at home fell unconsciously, and I always had to put on the water before taking a bath, and I felt that it must be ** air leakage.
I think it's a ** air leak, but I haven't found a place, and by chance I found that the plug of the radiator has a trachoma, and the trachoma is slowly leaking. After consulting the plumber, he said that the problem was easy to solve, and gave me two plugs to change when I went home.
When I went home to change, I also discovered a big secret. In the past, when the head of the radiator was not hot, the top of the radiator plug was often unscrewed, and a little water was put in it, and the head of the radiator was hot.
In the past, when the gas was deflated, there was very little release, and a little water would be discharged, but because the water discharged was small, the water discharged was clear. But this time the plug was changed, and the displacement was very large, which directly subverted the original cognition, and the water discharged was as black as ink.
The reasons for the formation of black water may be:
When the heating system is not used for a long time and the valve is closed, the water in the pipes will be stationary, and the impurities in it will gradually settle, resulting in black water in the radiator or underfloor heating in the poorly flowing area.
At that time, when changing the plug, I was afraid that the water would spray out, so I twisted it with a wrench and covered it with a towel to prevent it from spraying too far, and I also received a basin at the bottom, although it was not too far away, but it also ended up with half a basin of water.
It was very strange to feel that the water that squirted out was not clear, but as black as ink.
Professionals suggest that you need to drain all the water in the pipes and ask professional pipe maintenance personnel to clean them. After that, the maintenance pipeline is regularly inspected. Carefully clean the heating pipes before heating every year to prevent the generation of black water.
Many homes are still underfloor heating, thinking that it should be similar to radiators, and black water may also appear. It is said that it is normal for the water to be clear.
Although the water released is as black as ink, the actual use is normal, and there is nothing abnormal. How to deal with it, because I am not a professional, I dare not talk nonsense, but there is no problem with using it.
It seems that the heating does need regular maintenance to keep the water fresh. How to maintain it, or leave it to the professionals. Black water may be just an exception, but it does feel strange how the water that I thought was clear could be so dark.
