When decorating or renovating a home, PVC drainage pipes are the basic building materials that cannot be avoided - the kitchen needs to drain wastewater, the bathroom needs to use sewage, and the balcony needs to connect to the washing machine. It is needed everywhere. But people who visit the building materials market for the first time are often confused by a pile of pipes: "How much is the PVC drainage pipe per meter? How can some sell for 5 yuan, and some cost 20 yuan?" In fact, there are many ways to hide the price difference. Today, the key factors such as specifications and brands are broken down and said, to help you choose the right pipe with cost performance.

first talk about the "specifications" that most affect the price - the specifications of the PVC drain pipe look at the "outer diameter" (unit mm). The most common ones in the market are 50mm, 75mm, 110mm, 160mm, corresponding to different uses and prices:

- 50mm: suitable for kitchen sinks, wash basins branch pipes, or small apartment balcony floor drains. Small diameter and less materials, the price is 5-8 yuan/meter (conventional wall thickness 1.8mm is about 5 yuan, thickened 2.0mm is about 7-8 yuan).

-75mm: suitable for balcony washing machine drain pipes, bathroom floor drain branch pipes. Price 8-12 yuan/meter (wall thickness 2.0mm is about 8-10 yuan, thickened 2.3mm is about 11-12 yuan).

- 110mm: "standard" of the main drain pipe and toilet drain pipe in the bathroom, which needs to withstand a large amount of water. Price 12-20 yuan/meter (regular wall thickness 2.8mm is about 12-15 yuan, thickened 3.2mm is about 18-20 yuan).

- 160mm: large drain pipe in villas/commercial places, price 25-40 yuan/meter (wall thickness 4.0mm is about 25-30 yuan, heavy 5.0mm is about 35-40 yuan).

Note here: Under the same specification, the thicker the wall thickness, the higher the price - wall thickness is directly related to pressure resistance. For example, 110mm thickened pipe can hold a large amount of water in villas, which is naturally more expensive than conventional pipe.

talk about brand differences - do not remember the specific brand, divided into three categories:

- first-line brands: with new PVC material, strict process, stable quality, the same specification price is 30% -50% higher than the second and third lines (such as 110mm tube about 18-20 yuan/meter), but can be used for twenty or thirty years.

- second and third line brands: cost-effective, new materials but slightly inferior process, moderate price (110mm tube about 12-15 yuan/meter), suitable for families with limited budgets.

- small brands/miscellaneous brands: the lowest price (110mm tube within 10 yuan), but mostly recycled materials - rough, dark color, easy to deform, with a few years to crack, later maintenance is more troublesome.

There are two hidden factors:

1. Raw materials: new material (pure PVC resin) is more expensive than recycled material, new material has no impurities, anti-aging, recycled material is easy to become brittle, and the sun will be damaged in a few years.

2. Auxiliary materials: elbows, direct heads, tee and other accessories are about 1-5 yuan/piece, when buying, ask the total price of "pipes + auxiliary materials" to avoid merchants "pipe cheap auxiliary expensive".

finally give you 3 purchase suggestions:

- first set specifications: kitchen 50mm, bathroom 110mm, balcony 75mm, don't buy big waste, buy small water plugging.

- Don't be greedy for cheap: pipes that are lower than the average price are most likely to be recycled materials, and would rather be expensive 5 yuan to buy new materials.

- Look at the test report: focus on "raw material type" (whether it is brand new material), "compressive strength" (whether it can withstand water pressure), "environmental protection indicators" (with or without heavy metals).

In fact, the price of PVC drainage pipes is essentially "you get what you pay for" - specifications determine the basic cost, brands determine the quality assurance, and raw materials determine the service life. To clarify these, you can directly ask in the building materials market: "110mm new material second- and third-tier brands, how much is one meter?" It will never be pitted again!
