The reasons for the slow water outlet of the solar water heater are:

1. The height of solar energy is not enough, resulting in insufficient natural pressure.

2. The water pressure in the water pipe is too low, and the pressure difference between the water tank and the nozzle of the water heater is very small, so the pressure after mixing water is small.

3. The nozzle holes are small and few, or partially blocked by impurities.

Treatment method:

1. Take a booster pump and turn it on when the solar energy outlet is used more.

2, when the water pressure increases.

3. Replace the nozzle with large water spray or clean the nozzle.

With the popularity of solar water heaters and the rapid development of China's economy, residents living in small high-rise buildings often encounter such a problem. The solar water heaters are full of water, but it is difficult to get water. Whether your solar water heater is a new product you just bought or a product that has been used for a long time, this problem has been bothering users. As we all know, for users who live in the middle floor, the water pressure in the tap water pipe itself is relatively small, and the water pressure is even smaller indoors. In the face of customers' doubts, the technicians of a solar water heater have provided the following two solutions after many researches and explorations: Scheme 1: Choose the right time to supply water. As we all know, it is generally not possible to supply water to solar water heaters during the day. It is easy to damage the water heaters when water is supplied under the sunlight. The best time is to supply water to the water heaters at night, and it is best to supply water to the water heaters at night when the total water consumption of residential buildings is relatively small. At this time, the water pressure will be relatively higher. ? Option 2: Increase the booster pump. Generally, the flow of water decreases as the residential building goes up, which is because the water pressure is not enough, which leads to the water can not reach the upper residential building. However, if a self-priming booster pump is added to the water pipe of the solar water heater, the water can be pumped into the solar water tank on the roof, so that residents living in the upper floor can easily use water without obstacles. In addition to the above two schemes, we should also remind you of the following two points: first, we should check the water supply pipeline of Taineng water heater. Now most of the domestic solar energy is installed with aluminum-plastic pipes, which will affect the water flow after turning or discounting. ? Therefore, it is necessary to check whether there is any discount when the pipeline comes down from the roof to the eaves or turns. If there is, it is necessary to smooth the pipeline repeatedly. In addition, we should always check the filter screen of the solenoid valve. In many cases, the slow water supply may also be caused by the blockage of the filter screen of the solenoid valve. Specific operation method: first unscrew the nut, then take out the filter screen, then brush it with a brush to clean up the dirt inside, and finally put it back as it is.

My balcony needs 25 words.

My mother planted many flowers and plants on the balcony, which is evergreen all the year round and full of life! Look, the sun is blooming fiercely, with pink, rose and crimson flowers.

Chili peppers are crowded together like fat dolls, and their heads are stuck up; The sky is lush; A vine hangs from the spider plant.

and the loofah, with green leaves, is as big as the palm of your hand, like handfuls of beautiful fans.

The vine tip of Luffa curls like a snail's antenna and grows forward along the balcony fence. The most interesting thing is that the vine tip must wrap around the front fence first, and then the vine climbs along.

I really have to admire its perseverance and courage! There are yellow flowers among the leaves, industrious bees collect honey among the flowers, and colorful butterflies sing on the petals.

Every day, I water and pull up the flowers and plants on the balcony, which brings infinite fun to my life!

At the end of my balcony composition

My balcony composition is long and covered with all kinds of flowers and plants.

firstly, it is a gardenia with strong fragrance.

in spring, it sends out buds like stamens.

in summer, it blooms its fragrant flowers in the hot summer, and the fragrance spreads throughout the room.

followed by the unyielding chrysanthemums, which are also called Huanghua, Jiuhua, Nvhua, Nissin, Jiehua, Zhuyu, Yanshouke, Yanshouke, Yinwei, Shouke, Gengsheng, Jinrui, Zhouying and Huangrui.

there are red, yellow, white, ink, purple, green, orange, pink, brown, snow blue, light green and other colors.

Chrysanthemum morifolium has been designated as the national flower in Japan.

In addition, the national flower of Italy is daisy, the national flowers of Germany and Malta are cornflower, the national flower of Denmark is cornflower, and the national flower of Latvia is cornflower.

Chrysanthemum is a perennial herb in Compositae. Besides, Chrysanthemum is one of the top ten famous flowers in China.

After the gestation of spring and summer, in order to fill the vacancy at this time, chrysanthemums bloom in the autumn when flowers wither, and the green leaves are layered on top of each other, setting off this beautiful chrysanthemum.

There are many kinds of chrysanthemums, including Chrysanthemum morifolium, Lan Ju, Chrysanthemum morifolium, Chrysanthemum morifolium, Huang Ju, Dendranthema morifolium and so on.

Chrysanthemum can be used as medicine, soaked in wine to make tea, made into cakes, cooked in porridge and used as chrysanthemum pillow.

finally, the cockscomb.

The cockscomb is panicum miliaceum. It looks like a cockscomb, so people call it a cockscomb.

The flowering time of Celosia cristata is from June to October, with thick petals and S layers, and few leaves.

I like my balcony.

Write an anthropomorphic composition on the topic of' My Balcony'

My classmates who have worked hard for a semester have finally ushered in their dream winter vacation.

Many things happened in my winter vacation.

it's sad; There is something unpleasant; There are also funny ones.

since my topic is "interesting things in winter vacation", what I wrote is a funny thing.

Chinese New Year is a joyous day, filled with laughter and laughter everywhere.

At about four o'clock in the afternoon of the first day of junior high school, my mother and I dragged our tired bodies back to a warm home (because my father is a policeman, he is struggling in his sacred job! I was hungry at about 6: 3, so my mother and I went to the basement to get food.

mom said; "Wander, don't forget to take the key.

"However, I didn't hear it. I just remembered to ask my mother after closing the door. "Where are the keys?" Mom said, "Didn't I let you take it?" I said, "No!" Mom said, "This is terrible, and I don't have my mobile phone. What can I do?" So, we knocked on the security door opposite the door, but there was no one inside.

now my mother panicked, and we all said in unison, "What's the matter now?" Suddenly, my mother said to me, "You wait here. I'll borrow my mobile phone downstairs, call your father and ask him to send me the key.".

"I looked at my mother at this moment. My beautiful and energetic mother didn't know where she was, and her hair was messy (just woke up); The worst thing is my mother's feet, red socks and small black sand shoes, as ugly as they are.

but there's nothing I can do at this time. finally, my mother cut her hair and went to spite of her image.

I only heard my mother calling downstairs, "Grandma Bai, please lend me your phone. I left my key in the basement.

"Grandma Bai said enthusiastically," Come on in! " After about five minutes, my mother came out from Grandma Bai's house. My mother told me, "Dad will be here soon.

"So my mother and I waited quietly for my father's return.

after a while, I felt someone coming up. I thought it must be my father and shouted, "Dad!" " When that man came up, my face suddenly became "feverish". It turned out that that man was just a brother not much older than me.

Dad came back within 3 minutes of the incident, and we finally walked into our house.

Composition: My balcony should be figurative and anthropomorphic.

My family has a beautiful small balcony, where all kinds of flowers and trees are planted. They have grown up slowly under the careful cultivation of my father.

the whole balcony looks like a small garden.

There are many kinds of flowers and trees: pomegranate trees, osmanthus trees, cherry trees, wisteria trees, camellias, hydrangeas and Chinese rose flowers. What's better is the bonsai. Some old branches are packed, and the top of the tree is slightly open, like a fish's mouth, and some are crooked, like an old man with a hunched back ... In spring and March, everything is rosy and green, and everything is revived.

The flowers and trees on my balcony are full of vitality after a long wait in winter.

They spit out tender green buds. After a few days, the leaves grew greener and more lush, and became a green ocean.

The most interesting thing is that some flowers and trees have produced colorful flowers.

There are red Chinese rose flowers, camellias, hydrangeas with various colors, white lilacs and pink bauhinia ... My favorite is the purple wisteria, which hangs in clusters on the tree. From a distance, it looks like clusters of grapes and purple wind chimes. It's beautiful! Every time after dinner, my father and I always sit on the balcony and watch these green trees and beautiful flowers. This has become a place for me to relax and play.

I love my little balcony.

[composition for primary school students: my balcony text: my balcony: Lin Anqi, class 3 (4) of Yifu Primary School in Enshi City, Hubei Province, planted five potted flowers on my balcony, and composition for primary school students: my balcony.

they have different shapes.

Look at this pot. It's beautiful. Look at that pot. It's beautiful, too.

every flowering season, pots of flowers compete for fragrance and beauty.

The first one who came to my house was an unknown and strange flower. Its leaves were three layers inside and three layers outside, which resembled Snow Lotus. Let's call it "Snow Lotus" for the time being.

The petals of "Snow Lotus" are oval, and there is a little pink thorn in the middle of the upper part, which is very interesting.

the second person who came to my house was the lotus flower.

The lotus leaves of Lingjian are long and narrow, with a prominent stem in the middle and serrated edges, and a thorn of about 3 mm at intervals.

The flowers are even more beautiful. They are fiery red, and the stamens are golden yellow, like a brush ... Begonia is also beautiful, with red stems and pink flowers, some in bud and some in full bloom, revealing tender yellow stamens.

as for the golden lotus and gardenia ... they haven't opened yet, so I'll introduce them to you when they open.

My home has 6 words,

My home has only my father, mother and me, my grandparents are still working in Xinjiang, and my grandmother and grandfather are taking care of my lovely little cousin in the country.

so they can't look after me.

from the time I was sensible, I knew that my parents were busy all the time.

because they have to go to work and take care of me, but they care about me all the time, which makes me feel very happy.

My father is very busy at work. He often goes out early and comes back late, and sometimes he goes on business trips! He left for several days, but he called home every day.

On weekends, my father will try to stay at home and have fun with my mother and me. He will teach me and my mother to play Tai Ji Chuan, listen to my stories, and cook a sumptuous meal in the kitchen for my mother and me to taste. Although I don't think it's as delicious as my mother's, we always enjoy it.

My mother is very hardworking. She works hard. Now she is an engineer in their unit, but she almost does all the housework in our family.

When she comes home from work, she always seems to be busy, washing clothes, cooking and searching information on the Internet. When my father didn't come home because of work, she had to help me with my homework, and then she waited for my father while watching TV.

My mother is kind-hearted and my father is an understanding person. They care about each other and seldom quarrel. As a daughter, I feel very happy.

just like that incident last night! My father and I are sitting on the sofa discussing study, and my mother is bringing us boiled water.

Dad accidentally dropped a book near us, and Mom was bringing us boiled water with a big smile on her face. Unexpectedly, Mom stepped on the book that Dad dropped, slipped and fell down at once.

I spilled boiling water on my father.

I just heard my father "ouch!" With a cry, I quickly pulled up my father's trouser legs, and then I quickly went to find medicine to wipe them for my father.

but dad didn't care so much. Instead, he helped his mother up and said, "Did you hurt?" Sorry, I shouldn't throw things around.

"Mom said quickly," I didn't look at the road, so I fell down, and you-stop talking, do you hurt? " "No pain," Dad said with a smile.

I smiled sweetly when I saw this scene.

I not only love my family, but also my parents.

my home composition

with a good mood, I went back to my hometown and found that my hometown has changed and become more and more beautiful! In the past, the path leading to my hometown was bumpy and dusty everywhere, with fields next to it.

Now, the path has become wide and flat, and many flowers and plants have been planted on both sides! In the past, there was no supermarket near my hometown, but only one or two small shops. People had to walk a long way and go to the streets to buy things.

Now it's changed. There are several supermarkets in my hometown town. The goods in the shopping malls are dazzling, which makes it much more convenient for people to buy things.

in the past, people lived in tile houses.

Some tile houses keep leaking when it rains; The tiles on some tile houses are going to break.

The walls of the house are made of mud bricks, and the light in the house is very poor ... Now, it has become a brand-new building.

In front of some buildings, evergreen landscape trees are planted.

The trees at the bottom of the tall trees set off each other, and all kinds of blooming flowers are really like a fairyland.

People are wearing clean clothes and standing on the balcony in the warm sunshine.

they are all beaming! In the past, there were no street lamps on both sides of the road, so people could only use flashlights and lanterns for lighting.

At present, there are various street lamps hanging on the roadside.

Every night, the street lamp shines like a flower, which is gentle and bright, shining in the silent night sky according to people and vehicles walking at night.

it is connected with the light from the surrounding people, and it has become a bright and peaceful rural still night map.

in the past, having a bicycle in the village was the richest man in the village.

But now, every household in the village is riding a motorcycle, and some people are even driving a car! Not to mention TV, mobile phone, computer, etc.
