Chapter 774 Conduction

Under the watchful eyes of everyone, Wu Electrician made a big blush.

Even if he pretended to be shocked, I'm afraid it won't work, right?

"It's strange, what's going on? There is still a leakage at home." He bent down suspiciously, looking at the heating rod through the glass of the fish tank.

The heating rod is lying on the bottom of the cylinder in good condition, and the indicator light is still glowing orange-red, indicating that it is working with electricity.

If it is impossible to be transferred, the boss did take a look at the heating rod just now, but Wu Electrician kept a close eye on it. Unless the boss is a part-time magician, it is impossible to transfer the contract under his nose.

"This is indeed a leakage at home," he murmured to some, wanting to prove that he was not lying.

Some have nothing to say.

She had preconceivedly believed Wu Electrician's words just now, and thought that the heating rod leaked electricity. Could it be that the merchant was wronged?

"How about it, old man? Is the heating rod still leaking electricity?" The boss countered with a smile: "If there is no leakage, do you have to compensate us for the loss of reputation? Of course, at your age, we don't need money. You just need to apologize in public."

Electrician Wu was ashamed and angry, his brain was about to explode, and his face and body were sweating from anxiety.

It's so embarrassing, isn't this really being blackmailed as a professional touch?

If I knew this earlier, I should really listen to my wife and stay at home honestly, so as not to lose this person

The old man next to him came over anxiously, trying to grab Lord Zhuang's hand, but he waved his hand vigorously to keep the old man away.

He looked at the heater rods for a while, and the power strip for a while, trying to find out the reason.

"Evil door really evil door"

The boss said to some: "Beauty, you promised to be a witness for us just now. Now that the heating rod does not leak electricity, shouldn't he apologize to us?"

"These" looked at Zhang Zian in embarrassment.

Zhang Zian had already understood it, and took two steps forward and said to Electrician Wu: "Old man, you can stretch out your hand, it's useless to continue soaking—it's quite cold here, in case you get rheumatoid arthritis again It's not worth it."

"My heating rod is really leaking electricity!" Electrician Wu stomped his feet anxiously.

Zhang Zian nodded, "I know, but if you try like this, you won't be able to get it out."

"Ah?" Electrician Wu was taken aback, then raised his eyes to stare at him, "Then how do we try?"

The boss frowned upon hearing this, "You handsome guy, don't talk nonsense."

Zhang Zian ignored him, pointed to the empty bucket in the corner and said, "Have you forgotten? Pure water does not conduct electricity."

The bottled water provided by this water dispenser is pure water, not mineral water.

One word awakens the dreamer!

Electrician Wu pulled out his wet hand from the water, and slapped his forehead, "I'm so confused! How could I forget this!"

Although he is an experienced electrician who has worked in the factory for more than 30 years, his usual work is dealing with strong and weak electricity in the factory, and he does not know how to deal with water. The water he comes into contact with in daily life contains impurities to some extent. Not as pure as bottled water.

Zhang Zian said: "You just said that the fish tank in your home is a seawater tank. The difference lies in this - seawater is rich in electrolytes, such as calcium ions, magnesium ions, sodium ions, etc., which are good conductors of electricity. If you keep For freshwater fish, even if the heating rod leaks electricity, you may not notice it, because the conductivity of seawater is 1 times that of river water and lake water, so is the heating rod really leaking electricity?”

"Probably." Zhang Zian glanced at the boss, "If you want to try, you can go to the first floor to borrow some sea water, but I don't think it's necessary."

The boss lowered his head as if he had lost a rooster fight, "There's no need to try."

Electrician Wu suddenly became energetic as if he had been beaten into chicken blood, and was about to repay the humiliation he had just suffered, but was stopped by Zhang Zian and asked: "Old man, please recall carefully, when you bought the heating rod, you said Are you going to use it for a seawater tank?"

"This..." Electrician Wu thought for a while, "Not really, I haven't decided whether to raise freshwater fish or seawater fish when I bought it.

what happened? "

Zhang Zian pondered for a moment, and the host reconciled: "When you bought the heating rod, you didn't make it clear that you were using it for a seawater tank, and seawater is not only highly conductive, but also highly corrosive to metals. Generally speaking, seawater Heating rods for tanks and freshwater tanks are not universal, and glass heating rods should be used for seawater tanks. If you said it was for seawater tanks, he still sold you a stainless steel heating rod, which is his fault, but since you didn't say it in advance"

Electrician Wu didn't think so deeply when raising fish. He only thought about what kind of fish to raise after tossing a set of equipment, and even if he decided to raise seawater fish in advance, he might not have thought about the conductivity of seawater and the corrosion of metals.

Then, Zhang Zian said to the boss: "As for your side, the mistake is even bigger. Since you know that pure water does not conduct electricity, you probably also know that seawater is very conductive. Even if the customer didn't say that he wanted to raise seawater fish, you are selling You should also fulfill your duty of reminder when heating the rod."

Zhang Zian saw through the boss' previous actions and thoughts, and was immediately extremely embarrassed and nodded.

"In my opinion, both of you are at fault in this matter, so why not give in to each other." Zhang Zian persuaded, "It is inevitable that electronic equipment will be damaged. The problem between the two of you is mainly due to the pre-sales communication."

As a member of the pet industry, Zhang Zian felt somewhat sympathetic to the boss. It was not easy to open a shop, so he said a few words of justice for him.

To put it bluntly, the key to this matter is that Wu Electrician kept a tank of seawater fish. If it is a freshwater fish, there may be no problem with the heating rod at all. Even if the leakage is very slight, it may not even be noticed by the human body.

Wu Diangong experienced great joy and great sorrow in a short period of time, and the resentment in his chest was somewhat relieved. He nodded in agreement and said, "Well, I really didn't explain it clearly."

The boss was of course very happy to see that the other party intended to reconcile. He immediately refunded the full amount and gave Wu a glass heating rod of the same wattage as a free gift.

But Electrician Wu waved his hand and refused, "Forget about it, but I really can't trust the things you sell in this store."

The boss smiled wryly, and retracted the glass heating rod in embarrassment.

Electrician Wu sighed, and asked Zhang Zian, "Even if it's a glass heating rod, it can't completely avoid the possibility of electric leakage, right?"

Zhang Zian nodded, "That's true. The equipment ages quickly in seawater. No one dares to pat their chests and guarantee that their heating rods will not leak electricity."

Electrician Wu rubbed the top of his son's head, and said as if he had made up his mind: "I'd better listen to my wife, don't raise fish anymore, even if you do, let's raise freshwater fish instead."

Between his personal hobbies and the safety of his family, he reluctantly chose the latter.
