PPR tube
1. First of all, look at the呢話 appearance. The high-quality tube ha音東s a smooth appearance, complet一車e identification, an相快d brand names on the acce務農ssories; inferior products cannot do 分站this. Because high-quality pipes use 1鐘黃00% imported PPR raw materials, an訊哥d low-quality pipes only use part of 熱車PPR raw materials, there is a 懂秒big difference in performanc和不e between the two.
2. Toughness: Good quality PPR車慢 pipe has good toughness and 很關can be easily bent into a ci紙媽rcle without breakin女愛g, while inferior quality pipe is more 水通brittle and breaks immediately.
3. Thermal expansion and劇城 contraction: good water科機 pipes can still maintain 答筆hardness at high water temperature錯資, while poor quality pipe錢快s are softened at 60 degrees 靜弟water temperature.
4. Service life: high-quality 視司products are guaranteed fo新可r 50 years, and inferior products謝業 can only be guaranteed fo道器r 5-6 years.

Aluminum-plastic composi吧通te pipe
1. Check the appearance of the prod河費uct
High-quality aluminum composite 看門pipes generally have動山 smooth outer walls. The trademarks用熱, specifications, applicable temperatur事有e, and number of meters are clea光門rly marked on the pipe wall. The manuf聽國acturer also printed the product不明ion number on the pipe 裡雜wall to monitor the quali討個ty of the product at any 要服time; the product is well package大照d and packaged The various logos on i道很t are equally clear, and the manufa數水cturer’s name, address, 道站telephone, etc. are all printed in視慢 prominent positions. The 作內fake and inferior products ge時們nerally have rough o銀都uter walls, unclear or inc朋知omplete markings, simple pac和林kaging, and unknown factory addr能不esses or telephone numbers.
2. The aluminum layer cann拍紙ot be ignored
A good aluminum-plastic composite pip哥銀e is welded at the overlap of the alumi錢森num layer, and the al錢朋uminum layer and the pla綠唱stic layer are tightly co他多mbined without delamination. On the聽劇 other hand, in the shoddy products線理, some aluminum layers are n技事ot welded at the lap joints, an公快d some aluminum layers and p用影lastic layers are of月聽ten stratified and not cl來間ose together.

Installation suggestions
1. It is best to find a professi紅公onal company to install PP-R pipes. N做房o matter how luxurious and high-end y哥微our decoration is, it will舊行 not be worthwhile if you 機見are not willing to spend money in th也錢is area. Often bursts 關市or blockages of pipelines will ca哥金use tens, hundreds of time水校s, or even immeasurable conse件爸quences to the price of the water 訊綠pipe itself.
2. After installatio照頻n, a booster test must be carried票懂 out. The boost test is gener風民ally carried out at 1.5 ti個城mes the water pressure, and there s術去hould be no water leakage du厭行ring the test.
3. A simple test method witho鄉唱ut pressure, but not completely feasib音裡le.
1) Close the water main valve. (器音Ie the water pipe switch 來呢on the front of the water meter)科件
2) Turn on the taps in the room 山你for 20 minutes, and turn off all taps a文算fter making sure that there is 要那no water dripping again.
3) Turn off the water inlet媽懂 switch of equipment現短 with water storage function s藍站uch as toilet tank and washing在醫 machine.
4) Open the main valve購西 of the water pipe.
5) Check whether the water meter 務黃is moving 20 minutes after算行 opening the main valve, includin費著g moving slowly.
If you move around, it 他訊is leaking. If you don't move aro服器und, you may be fine. (If校醫 there is a problem with the water 商大meter or the water pipe is s章的lightly seeped, it may be diffi用樂cult to determine.) Therefore在時, it is recommended that資跳 a water pressure test experiment be 答哥carried out after the construct長師ion. Generally, the pre物訊ssure is 10-15 kg, and 書跳the time is 20-30 minutes. (Better to 動土check it in person)

4. Direction of water大靜 pipe:
It is recommended that the water購風 pipe is the safest to go from t請還he top. The main reas雜術on is that most of the waterway transfo睡北rmations are concealed pi弟公pes, and the characteristic of water 近黃is that the water flow光樂s to a lower place. If 好通the pipeline goes underground, it 了靜is difficult to find wate司公r leakage in time. O農裡nly when the water overflows th件友e Jinshan or the floor煙議 is deformed and leaks dow他又nstairs, the water leakage will be fo謝多und, and it is difficult to自志 find the leaking pla上著ce because the water pipe i公低s buried in the dark. At this time, t你子he huge loss is even more irre大短versible, and even ser服關iously affects the friendly nei廠店ghbor relationship; if the w化相ater pipe goes to the top, the wa個南ter reform cost may be higher, 放女but as a long-term investment玩亮, it is worthwhile. Even if t市裡he water pipe is on the top, it 些船can be found in time, which is con件技venient for maintenance and the l黃校oss is small.
5. In daily life, if you find t問跳he following conditions民數, please check the relevan西兵t pipelines as soon as possible:
The water pipe goes underg對日round:
1) Mould and blisters on the wa歌廠ll paint surface
2) The skirting line or woo小年den floor is black an路玩d the surface has fine bubbles空對
The water pipe goes to the top:
1) Dampness or water drop新黃s appear on the cano作了py
Common skills
(1) Waterway design must 開唱first consider all wate車樹r-related equipment, such as 商外water purifiers, water heaters, kit個水chen treasures, toilets的很 and wash basins, etc., t睡暗heir locations, installation met秒黃hods, and whether ho技刀t water is needed;

(5) There should be a supp讀空ression test after the waterway reco東紅nstruction, but many decoration tea我上ms did not have a suppressio亮風n test. They will use many methods道中 to deceive you, say費電ing that there is no need to su懂志ppress it, there is w可冷ater in the pipe, there i你還s pressure, and so on.
(6) It is best to have t自北he owner present in the suppressi街低on test, which can play a s通師upervisory role; becau有校se some decoration t銀作eams will deceive the owner媽吃 in this link. The method is: when 中木suppressing, open th影相e "return valve" of the pum唱呢p to form a loop. Althoug西鐘h the pump seems to be working山兵, there is not much pressure in the子生 tube. Especially for the el得也ectric pump, students should pay more美還 attention. If you don’t understa機國nd, please ask a profession放從al to help you take 物制a look.
(7) When receiving the house, you紅那 should check whether ea到購ch drain in the kitchen a化山nd bathroom is unbloc著樹ked.

Installation of electric wat快的er heaters and faucets:

1. Ensure that the dis電請tance is 15 cm (most of the electric 分門water heaters and taps have a 她西distance of 15 cm between hot and cold城物 water supply, and some a煙雨re 10 cm);

2. The heights of the cold and h會能ot water pipes are the same;

3. The cold and hot water 喝們pipe openings are vertical to t風一he wall, and you should also pay atte木計ntion to not let the bricklay司男er get crooked when a美舞ttaching the wall tiles (呢兒if it is not vertical, the subseq睡愛uent installation may都間 be laborious);

4. Cold and hot water pipe o姐照penings should be two centime妹靜ters higher than the wall. When la醫物ying wall tiles, bricklayers sh什是ould also be required to ensure that 雜間the wall tiles and the water pip做科e nozzles are at the same level aft就拍er laying the wall tile湖村s. If the size is not suitable, inst匠服alling electric wate要近r heaters, faucets, etc.刀都 in the future, it is 山腦likely that you will need to purchas制訊e additional pipe clamps, inner wire裡市s and other connectors to complete t報店he installation.
