2, water pipe dealers often discount promotions, are generally 6-6.5 fold, etc., but it should be noted that dealers will only discount the sale of water pipes, accessories such as elbows, tees, valves and the like are rarely discounted, Or the discount is lower. In accordance with the calculation of one kitchen and one bathroom, plus a water pipe to the balcony, a maximum of 15-20 meters of water pipes, even if all calculated according to the hot water pipe, in accordance with the market price of 14 yuan / M hit 6 fold, but at most only more than 200 blocks.
But joints, tees, and valves are not cheap if they are not discounted. Water pipes and fittings are like ham and straw, so many netizens are buying discounted pipes at discounted prices. The reason for this is that the total price is not much cheaper.
So be sure to ask clearly, write in black and white, and agree that everything, including water pipes and fittings, is a discount before agreeing to the vendor to install. And it must be stated that in accordance with the actual materials used for settlement, we should be optimistic about whether the water pipes brought by the workers are short (that is, other people are left home), and before the start of construction, we must count the number and types of all the water pipes that the workers bring. Only after the approval of the workers can the construction be started.
After the completion, the remaining pipes of the broken head must not be allowed to be taken away by the workers, and they would rather be thrown away and could not be given to him. Except for deducting construction funds, the remaining pipe (above 0.65M) can be deducted at a discount of 80% of the actual purchase price.
Accessories do not have to be so complicated and easy to inventory.

Welding costs, a kitchen and a defender 120 yuan, a kitchen and two bathrooms 150 yuan. Do not pay for other expenses.

generally. The 500-600 can put all the water pipes in place.
By the way, the purchase price of PPR plumbing fittings is generally 40-50% of the retail price, and absolutely no more than 55%. Therefore, if the JS hose fittings are uniformly sold for 6-6.5 percent of sales, it is acceptable. Let JS make some money! ! Isn't it?

In general, with a wall of 2.3 or 2.8, 1.6MPA pressure is enough for home use.
