How about submarine floor drain? Friends who have used submarine floor drains talk about it.

My floor drain faucet angle valves are all submarines. It was the first time that I saw the goods being renovated in the new building of the unit during my internship in 29. I saw the jumping odor-resistant floor drain for the first time. At noon, I went to the opposite small building materials market and bought a stainless steel unit. The price of the same series was 29 yuan. I bought a round one. It took less than one and a half years for the core to jump, and I went there to buy a core for 15 yuan. Now it is unified online and 25 yuan has been used all the time. Right. This brand also has a degree of trust. In 16~17 years, I bought angle valves and faucets. The garbage copper bodies of Nima are all of good quality, but the valve cores are all of the kind of 5 cents. One of the faucets with a price of 129 yuan was also leaking for more than a year. Later, when the dog hole applied for maintenance, people sent another one, and they removed the pieces. It was found that there was nothing wrong with the porcelain pieces of the valve core. The brass frame material was too soft and bumped and deformed, which caused the pipe faucet to actually open from the other end. It should be that kind of tolerance. The fake brass tube material of the easy-to-crack tube is absolutely junk. Now, the price of this brand is really expensive. The floor drain of Wrigley with the same specification is only 69 yuan, while the stainless steel+plastic base of submarine, which I bought in 29, is a reduced version. Now there is no screen and no water separator core, which is cheaper. 69 submarines have no brass base. Even the copper-plated floor drain with more than 1 yuan is also a plastic base.
