How much does the negative pressure water supply equipment for the water tank be? If the design is free?

Answer:
1, in view of the water supply industry leader in the sense of responsibility and sense of mission, wholeheartedly for each customer to provide the most professional, best quality, the most comprehensive service. For each customer (including those who do not cooperate with our customers, or users of this water supply problems), provide free consultation, free design, free training of quality services.
In 2, the company won a non negative pressure water supply equipment prices ranging from tens of thousands to tens of thousands of households, because, each high-rise building water supply, the total number of building floors are not the same situation, so the equipment flow, Yang Cheng, power, equipment specifications, size is not the same, so each free negative pressure water supply equipment is not the same price. (for example: 1 project water supply number of households is 150, the floor is 12, 2 of the water supply project number of households is 200, the floor is 20, then 1 and 2 project project flow, lift and equipment size and power are not the same, so their price is certainly not the same.)
