Under everyone's gaze, Electrician Wu's face turned red.
Even if he pretended to be electrocuted, it probably wouldn't work, right?
"That's weird. What's going on? It's still leaking electricity at home … "He bent down in confusion and looked at the heating rod through the glass of the fish tank.
The heating rod was lying at the bottom of the tank, and the indicator light was still on with an orange-red glow, indicating that it was working.
It was impossible to say that it had been replaced. The boss did pick up the heating rod and look at it, but Electrician Wu was watching very closely. Unless the boss was a part-time magician, it would be impossible to replace it under his eyes.
"This … it's still leaking electricity at home …" he murmured to Snowy, trying to prove that he was not lying.
Snowy had nothing to say.
She had just believed Electrician Wu's words and thought that the heating rod was leaking electricity. Could it be that the shop owner was wrongly accused?
"What do you think, sir? Is the heating rod still leaking electricity? " The boss laughed and retorted, "If it's not leaking electricity, do you have to compensate us for the damage to our reputation? Of course, since you're so old, we won't ask for money. You just have to apologize in public. "
Electrician Wu was embarrassed and angry. His brain was about to explode, and his face and body were covered in sweat.
This was so embarrassing. Wasn't he being treated as a professional scammer?
If he had known this would happen, he would have listened to his wife and stayed at home, so that he wouldn't be embarrassed …
The little grandson next to him walked over worriedly and wanted to hold his grandpa's hand, but he waved his hand forcefully to stop his grandson from coming over.
He looked at the heating rod, then at the plug board, trying to figure out the reason.
"Weird … Really weird …"
The boss said to Snowy, "Pretty lady, you promised to be a witness for us just now. Now that the heating rod is not leaking electricity, shouldn't he apologize to us? "
"This …" Snowy looked at Zhang Zian awkwardly.
Zhang Zian had already understood. He took two steps forward and said to Electrician Wu, "Sir, give me your hand. It's useless to keep soaking — the weather is quite cold. If you get rheumatoid arthritis, it won't be worth it."
"I … This heating rod is really leaking electricity …" Electrician Wu stamped his feet anxiously.
Zhang Zian nodded. "I know, but you won't find out if you keep trying."
"Ah?" Electrician Wu was stunned and stared at him. "How do we try it?"
The boss frowned. "Hey handsome, don't spout nonsense."
Zhang Zian ignored him. He pointed at the empty bucket in the corner and said, "Did you forget? Pure water does not conduct electricity. "
The water dispenser was equipped with purified water, not mineral water.
His words had awakened the dreamer!
Electrician Wu pulled his wet hand out of the water and slapped his forehead. "I'm so old and confused! How could I have forgotten about this! "
Although he was an experienced electrician who had worked in the factory for more than 30 years, his usual work was dealing with the strong and weak electricity in the factory. He did not deal with water. The water that he came into contact with in his daily life contained impurities and was not as pure as bottled water.
Zhang Zian said, "You just said that the fish tank in your house is a seawater tank. This is the difference — seawater is rich in electrolytes, such as calcium ions, magnesium ions, sodium ions, and so on. They are good conductors of electricity. If you raise freshwater fish, even if the heating rod is leaking electricity, you may not notice it because the conductivity of seawater is 1,000 times higher than that of rivers and lakes. "
Snowy suddenly understood. "In other words, this heating rod is really leaking electricity?"
"Probably." Zhang Zian glanced at the boss. "If you want to try, you can go to the first floor and borrow some seawater, but I don't think that's necessary."
The boss hung his head like a rooster that had lost a fight. "There's no need to try."
Electrician Wu suddenly felt like he had been injected with chicken blood. He was about to return the humiliation he had just received, but Zhang Zian stopped him and asked, "Old man, can you recall carefully? When you bought the heating rod, did you say that you were going to use it for a seawater tank?"
"This …" Electrician Wu thought about it. "No, I didn't. When I bought it, I didn't decide whether to raise freshwater fish or saltwater fish. What's wrong?"
Zhang Zian pondered for a moment and tried to mediate. "When you bought the heating rod, you didn't make it clear that you were going to use it for a seawater tank. In addition to being highly conductive, seawater is also highly corrosive to metals. Generally speaking, heating rods for seawater tanks and freshwater tanks are not interchangeable. Seawater tanks should use glass heating rods. If you had said that you were going to use it for a seawater tank, he would still have sold you a stainless steel heating rod. That would be his mistake, but since you didn't say it in advance … "
Electrician Wu didn't think so deeply when he was raising fish. He only thought about what fish to raise after buying a whole set of equipment. Even if he had decided to raise saltwater fish in advance, he probably wouldn't have thought about the conductivity of seawater and the corrosion of metals.
Then, Zhang Zian said to the boss, "As for you, you made a bigger mistake. Since you know that pure water doesn't conduct electricity, you probably also know that seawater is very conductive. Even if the customer didn't say that he was going to raise saltwater fish, you should have done your duty when you sold the heating rod. "
The boss's little tricks and thoughts were seen through by Zhang Zian. He suddenly felt very embarrassed and kept nodding.
"In my opinion, both of you are at fault in this matter. Why don't we both take a step back?" Zhang Zian tried to persuade him. "Electronic equipment damage is inevitable. The problem between the two of you is mainly in the communication before the sale."
As a member of the pet industry, Zhang Zian more or less sympathized with the boss. It wasn't easy to open a shop, so he spoke up for him.
To put it bluntly, the key to this matter was that Electrician Wu had raised a tank of saltwater fish. If it were freshwater fish, the heating rod might not have had any problems at all. Even if there was an electrical leakage, it would be very slight and might not even be noticed by the human body.
Electrician Wu had experienced great joy and great sorrow in a short period of time. The resentment in his chest had somewhat dissipated. He nodded and agreed. "Okay, I really didn't explain it clearly."
Seeing that the other party was willing to reconcile, the boss was, of course, very happy. He immediately gave a full refund and even gave Electrician Wu a glass heating rod of the same wattage for free.
Electrician Wu waved his hand and refused. "I'll let this matter go, but I really don't trust the things you sell in your shop."
The boss smiled bitterly and awkwardly took the glass heating rod back.
Electrician Wu sighed and asked Zhang Zian, "Even if it's a glass heating rod, it can't completely avoid the possibility of electrical leakage, right?"
Zhang Zian nodded. "That's true. The equipment ages very quickly when it's soaked in seawater. No one can guarantee that their heating rod will definitely not have electrical leakage."
Electrician Wu rubbed his little grandson's head and said as if he had made up his mind, "I'll listen to my wife. I won't raise fish anymore. Even if I do, I'll raise freshwater fish."
Between his personal interests and the safety of his family, he reluctantly chose the latter.
