PPR tube
1. First of all, look at the ap女黑pearance. The high-quality tube h自時as a smooth appearance, complete ide腦鐘ntification, and brand names on the 家筆accessories; inferior product呢站s cannot do this. Because分爸 high-quality pipes use 100% importe冷又d PPR raw materials, and low-quality pi事媽pes only use part of PPR ra近務w materials, there is a big聽習 difference in performance人公 between the two.
2. Toughness: Good quality PPR pipe 訊人has good toughness and can be easily能我 bent into a circle without breaking, w銀要hile inferior quality p朋兵ipe is more brittle and break照呢s immediately.
3. Thermal expansion and contractio間歌n: good water pipes can聽看 still maintain hardn些司ess at high water temperatu議票re, while poor quality 分拿pipes are softened at 60 笑答degrees water temperature.
4. Service life: high-quality products低白 are guaranteed for 50 years, 來樂and inferior products can only be guara費相nteed for 5-6 years.

Aluminum-plastic composite p笑行ipe
1. Check the appearance of the p頻見roduct
High-quality aluminum composite玩西 pipes generally have習民 smooth outer walls. 用林The trademarks, specifications, applic書姐able temperature, and n購媽umber of meters are clearly 麗風marked on the pipe wall. The manufac厭謝turer also printed the producti她費on number on the pipe wall to monitor員大 the quality of the pro廠妹duct at any time; the product i生多s well packaged and packaged The藍近 various logos on it are equ動姐ally clear, and the manufactu區男rer’s name, address,著你 telephone, etc. are all print答舊ed in prominent positions. The f喝是ake and inferior products generally 舊秒have rough outer walls, uncl做不ear or incomplete markings, 雪議simple packaging, and unknown fa村煙ctory addresses or t樹筆elephone numbers.
2. The aluminum layer cannot be行刀 ignored
A good aluminum-plastic composite 要數pipe is welded at the overlap of t火輛he aluminum layer, and th書是e aluminum layer and th玩美e plastic layer are tigh信歌tly combined without delamination.司笑 On the other hand, in the shod技白dy products, some aluminum layers門電 are not welded at the lap joi數作nts, and some aluminum layers and 拿很plastic layers are often st年好ratified and not close together.

Installation suggestions
1. It is best to find a professio他歌nal company to install PP-R pipes.票化 No matter how luxuri放唱ous and high-end your deco商唱ration is, it will not be worthwhile綠務 if you are not willing to spe市離nd money in this area. O紙子ften bursts or blockages of pipe年習lines will cause tens, hund路美reds of times, or even immeasurable 看房consequences to the price of the wat工拿er pipe itself.
2. After installation,請妹 a booster test must be carr煙兵ied out. The boost test is generally c弟離arried out at 1.5 times the wa用上ter pressure, and there行為 should be no water leak做得age during the test.
3. A simple test method without p可鐘ressure, but not completely feasible亮上.
1) Close the water main西小 valve. (Ie the water 慢空pipe switch on the front of 他熱the water meter)
2) Turn on the taps in the room for 20 錯去minutes, and turn off all醫厭 taps after making s船用ure that there is no water dripping aga上事in.
3) Turn off the water inlet 房錯switch of equipment with兒窗 water storage functio冷兵n such as toilet tank微歌 and washing machine.
4) Open the main valve of the wat女暗er pipe.
5) Check whether the water meter is mo東國ving 20 minutes after openin舞月g the main valve, including m通慢oving slowly.
If you move around, it is leaking. If y錯拍ou don't move around, you ma民兒y be fine. (If there is a proble服討m with the water meter or the wa市看ter pipe is slightly seeped他西, it may be difficul東煙t to determine.) Therefore, i拍腦t is recommended that a water p城空ressure test experim妹老ent be carried out aft訊河er the construction. General筆跳ly, the pressure is 10-15 kg,音見 and the time is 20-30 minutes近還. (Better to check it in person)

4. Direction of wate低煙r pipe:
It is recommended that司呢 the water pipe is the safest習習 to go from the top. The算費 main reason is that 白少most of the waterway transformations ar讀生e concealed pipes, and the characterist物拿ic of water is that the water fl亮行ows to a lower place. If th水錯e pipeline goes undergr輛木ound, it is difficult to如明 find water leakage in time.空頻 Only when the water overflows 年湖the Jinshan or the f業錯loor is deformed and leaks downstairs,明醫 the water leakage will鄉南 be found, and it is difficult to 火見find the leaking place be公很cause the water pipe is buried務老 in the dark. At this ti還爸me, the huge loss is even more 外件irreversible, and even seriously a子答ffects the friendly neighb家什or relationship; if the water pipe goe熱少s to the top, the water reform co船遠st may be higher, but as a long話這-term investment, it物影 is worthwhile. Even if the 頻店water pipe is on the top, it can be 城劇found in time, which is convenient 東生for maintenance and the loss is smal時畫l.
5. In daily life, if you find弟我 the following condition男習s, please check the relevant pipelin美用es as soon as possible:
The water pipe goes under鐵看ground:
1) Mould and blisters on the wal不美l paint surface
2) The skirting line or妹弟 wooden floor is black多風 and the surface has fine bubbles
The water pipe goes t通慢o the top:
1) Dampness or water雨知 drops appear on the canopy
Common skills
(1) Waterway design must fir現樹st consider all water-related麗飛 equipment, such as water p了說urifiers, water heaters, kitchen冷綠 treasures, toilets and wa個醫sh basins, etc., their locations, ins短算tallation methods, and w謝店hether hot water is needed;制朋
(2) It is necessary to mak熱車e good use of gas or elect化友ric water heaters in advance to a西可void temporary replacement of wate森區r heater types, which may lead t制筆o repeated reconstruction 業聽of water circuits;
(3) In addition to leav下書ing the toilet for the wash basin, 拿森toilet, washing machine and other wate訊歌r outlets, it is best to connect one男著 out. It is convenien新道t to receive water and 厭弟mopping the floor lat弟鄉er; it depends on the owner's preferen視吃ce.

(6) It is best to have the owner 笑那present in the suppression t也在est, which can play a sup中北ervisory role; because some decorati草月on teams will deceive the own嗎吃er in this link. The method is少不: when suppressing, ope窗來n the "return valve" of the理民 pump to form a loop. Alth物要ough the pump seems to be worki你上ng, there is not much pressure in新喝 the tube. Especially for the electric章家 pump, students should pay知吃 more attention. If you do視線n’t understand, please ask a professi老謝onal to help you tak下友e a look.
(7) When receiving the house, you shou空男ld check whether each drai就很n in the kitchen and bathr看吧oom is unblocked.

(12) When renovating t亮南he waterway, four points shou鄉他ld be paid attention to 木謝in the cold and hot water supp風高ly pipes reserved for t信到he future

Installation of electric water he銀近aters and faucets:

1. Ensure that the distance 謝志is 15 cm (most of the electri中草c water heaters and taps have a玩生 distance of 15 cm between hot and co我相ld water supply, and some窗著 are 10 cm);

2. The heights of th火人e cold and hot water pi我愛pes are the same;

3. The cold and hot water pipe open銀學ings are vertical to the wall, an黑輛d you should also pay 呢呢attention to not let 月睡the bricklayer get crooked when attachi門作ng the wall tiles (if it is n問花ot vertical, the subsequent installatio議他n may be laborious);
