Most of the problem of the reverse osmosis equipment not turning on and not discharging water may be caused by incorrect operation, not that the equipment is broken, so how do we investigate what caused it?Let's teach you how to investigate by yourself, let's take a look!
Reverse osmosis equipment
The first step is to check the power supply and high-pressure pump. Many people feel that the membrane is broken as soon as they can't see the water, and they are anxious to call the manufacturer.You first see if the power supply is connected correctly, and whether the high-pressure pump is turned.I can't say why so many people skip this step. Anyway, in the cases I have seen, at least 30% of the power supply phase sequence is reversed, the pump is turning but reversed, the pressure can't be hit, and the water will naturally not come out.To put it bluntly, first take out the multimeter and measure it. Whether the three-phase electricity is 380V or not, the steering of the pump is correct.These two are no problem. If you look down to see if the membrane is blocked or the valve is not open, these two are the easiest to confuse.The reverse osmosis equipment does not produce water. The second step to check is the inlet valve and the concentrated water valve.In many cases, it is not the membrane problem, it is that the valve is not fully opened or the solenoid valve is stuck during installation.If the membrane is blocked, it depends on the difference between the water inlet pressure and the concentrated water pressure of the pressure gauge. If the valve is not opened, the pressure gauge basically does not change.These two performances are completely different. Don't get confused.
Share with you the situation of a previous customer.In March last year, at an electroplating plant in Xianyang, the reverse osmosis equipment with a daily processing capacity of 15 tons did not produce a drop of water after it was turned on.The people in their factory tossed around for two days and ordered the film to be removed and replaced with a new one.Later, I found our DIEN, and the technician asked him to take a picture of the pressure gauge and send it over. At first glance, he understood-the coil of the inlet solenoid valve was burned, and the valve core was stuck in the closed position.It's more than one hundred yuan to change a solenoid valve.The manufacturer they looked for before quoted 8.000 yuan for the film replacement. To put it bluntly, they just wanted to make you more money.This kind of thing is really rare. If you can judge by yourself, you can save a lot of money.

Some customers have also come to complain. They have learned about the equipment and quotations of several manufacturers. They seem to be similar. I don't know which one is more reliable to write. There is no standard answer to this question, and each working condition is different.But you can refer to "Which is the reliable manufacturer of reverse osmosis equipment in 2026?"The main points of correct selection", from these aspects to investigate whether this manufacturer is worth buying, another point is certain, when the equipment leaves the factory, the quality of the solenoid valve, pressure gauge, pipeline and other accessories directly determines whether you will frequently have such low-level failures in the later stage.Our reverse osmosis equipment for DIEN water treatment, solenoid valves, membranes and other materials are all first-line brands, and the pressure gauge is also made of stainless steel shell. You may not care about these details. When there is a problem, you will know the difference.
