Can solar sewer lines still be used? If you need to replace it, have a plumber check it for you. He will install it frequently and be able to identify it and plug it back in!

Another way is to check the brand of the sewer pipe. If it is Weixing pipe, there will be a video of the wiring diagram recorded on the website during the construction of water and electricity. enter part number

1. The surface is smooth and clean, and the tube body has no stains, no gas pipes, no scratches, and no scratches on the film (this phenomenon will affect the heat collection efficiency

and magnificent).

2. The color of the film layer is mainly blue and black, and the overall color difference is small. But black does not mean the vacuum tube is of good quality, because some manufacturers often make the film layer completely blackto mask the noise. In fact, some color errors of vacuum tubes are inevitable and do not affect the heat collection efficiency of vacuum tubes.

3. The fired mirror surface is complete, smooth and translucent, without blackening or blackening.

4. There are three best vacuum tubes on the market: high temperature tubes, high efficiency tubes and high temperature tubes. The film layer of high temperature tubes is longer than that of ordinary tubes (about 1cm from the tube mouth). This tube is resistant to high temperatures and has strong resistance to attenuation. The film layer will not age, fall off or fade when exposed. in air at high temperatures of 400°C. The high-efficiency tubular film layer is about 2.5 cm from the tube mouth. This tube has ultra-high absorption, less heat loss, increasedrapid temperature rise and high thermal efficiency. Alpine tubes feature the advantages of high efficiency tubes with high thermal efficiency and rapid temperature rise. At the same time, they have less heat loss and can still produce hot water at -30°C. Consumers can choose different vacuum tubes according to different areas.

5. To the naked eye, the color of the inner tube is dark red, indicating that its bottom metal layer is copper. This type of vacuum tube can also work normally under. severe cold conditions, -30℃ Discharge hot water as usual. High quality vacuum tubes are generally used for more than 15 years, which is directly related to the lifespan of the solar water heater. Nowadays, the quality of most manufacturers is uneven, so consumers need to open their eyes and identify them carefully.
