1. Pay attention to the price of water pipes and fittings.
The ratio of general water pipes and fittings is (60% to 65%): (40% to 35%). Let's say you bought a 1000 yuan water pipe material, where the price of the pipe is 600-650 yuan and the price of the accessory is 400-350 yuan.
Some plumbing distributors often attract customers' attention with very low pipe prices, and then raise the price of accessories to sell. This will inevitably increase the price ratio of accessories, and sometimes the price of accessories will exceed 50% of the total price. Taking the “inner wire elbow†in the accessories as an example, its price is generally equal to the price per meter of pipe. If you buy a water pipe of about 9 yuan per meter, the price of the inner wire elbow is usually not higher than 9.5 yuan. If the price of the inner wire elbow is more than ten yuan, you should pay attention to it.
2. When purchasing a water pipe inquiry, the specifications of the pipe must be used as the premise. We must clearly express the brand, outside diameter, and wall thickness of the pipe after inquiry. For example: How much is the price of a hot water pipe 25*4.2 Linglong brand one meter?
If you ask the price of the hot water pipe in general, the merchant will have a chance to play tricks, because the 20*2.8, 20*3.4, 25*3.5, 25*4.2 water pipes can be sold to you as hot water pipes.
3. When shopping around, pay attention to the comparison with the specifications, based on the total price you can compare prices, let the business budget for you about the total price of water pipe materials. Then based on the total price, decide where to buy.
Please pay attention when comparing goods: 1. Make sure to compare them with the same specifications. For example, you can't compare the 25*3.5 water pipes of the A brand with the 25*4.2 water pipes of the B brand; On the same brand of products, the prices of different merchants are compared. 3. If you are not really sure where to buy, do not deliberately and seriously to bargain, otherwise the merchants will think that you are buying in good faith to counter-offer. Do not think that you are simply asking and comparing. 4. If you are not really sure where to buy, if you want to take away the list of budgets that the business has calculated for you, ask for permission from the business.
4. After the purchase of water pipes, pay attention to the merchant's delivery situation. Once the water pipe transaction is completed, be sure to carefully confirm the merchant's delivery situation: whether the brand of the water pipe is correct; whether the water pipe wall thickness is correct; if the brand of the fitting is with the pipe The brand is the same; the quantity is consistent with the quantity on the delivery list; whether the brand name, outer diameter, and wall thickness of the water pipe are clearly marked on the purchase list.
In short, at the time of inquiry, let the merchant take a look at the physical sample first, and when it is shipped, confirm whether the goods are consistent with the sample.
5. Material Installation and Return of Excess Materials
(1) Confirm the actual use of the material when installing the material
(2) When the individual material is missing, the first material purchase list is brought along with the same preferential price as the first purchase.
(3) When installing on the construction site, pay attention to maintaining the cleanliness of unused pipes and fittings, and facilitate the return of unnecessary materials.
(4) When the spare parts are returned, all the front-to-end purchase lists will be brought on. If the secondary sales of the business are not affected, the original price can be requested for return. (The amount of conventional return is not more than 10% of the total purchase price.)
6. Comparison between domestic PP-R products and imported PP-R products Since the late 1990s, China has entered the period of high-speed development of PP-R raw materials research and development, and after years of experience, China now has its own R&D. , PP-R production technology has long been mature, in the strict implementation of China's PP-R national standards under the premise of similar manufacturers of product quality performance should be little difference.
Most PP-R pipes in the domestic market are produced using raw materials from Borealis, Korea, and China. In general, due to the import tariff, the prices of PP-R products and imported PP-R products produced using foreign materials will be higher.
