Replacement of water standpipes, what mistakes are made?

System of water supply of apartments. Its main artery, considered plumbing risers extending between the floors, which are connected to the water supply of apartments.

This refers to water in apartments being distributed through separate pipes for hot and cold water for bathrooms and kitchens. If you plan to complete replacement of pipes in the bathroom, you must define the replacement of risers between floors. They can be changed, both in combination with pipes in your bathroom and kitchen, or do not touch it, if the new risers, as an example, in a new building. It’s also possible to replace part of the risers between the floor and ceiling, thus, the tube extending through the overlap with the top and bottom remain. If it is possible to agree with the neighbors from the bottom and from the top, and a pipe between the beams (ceiling and floor) can be replaced.

If risers are not planned to be replaced, new wiring tubes are produced from threads welded to the riser hot and cold water. Thread welded to the riser, this is the starting point. In the lead-welded thread is wound on the whole flat valve, installed after the pressure reducer (if necessary), water meters, and cleaning is carried out the wiring of new pipes. Wherein pipe laying is performed as in the wall and outside (after installation of ceramic tiles). It should be planned initially before you decide to “call a plumber in Phoenix” to view and advice.

How much does the plumbing work cost and what it determines the total amount?

For ease of calculating the cost of plumbing work, applies the concept of “point”. For example, in your apartment: kitchen sink, bathtub, bathroom sink, toilet, and water heater are the amount of these appliances that is equal to the number of points. The point refers to completely laying pipes for hot and cold water (from the counter) and the sewer pipe from the sewage rise. Knowing the value of the point and the number of devices (points), we derive the total cost of plumbing work. If the point of the cost is too low in relation to other private plumbing, the guarantee that after the laying of pipes and repair in the bathroom, the same plumber installs sanitary devices is the minimal amount of payment. Therefore, we strongly recommend not to use the services of casual ad plumbers, after which have to redo all the work. Replacing the riser is a separate category, and depending on whether all or part of the riser is being replaced, the price will be formed for the installation. If it’s necessary to replace the used welding in the riser, the operation cost will increase.

A situation where the necessary welding works – high wear of the metal riser, poor access to the riser for tapping the plate.

Replacing the heating risers.

Replacement is carried out according to this principle, as well as water supply risers. You can either replace the entire riser from the neighbors from the top and bottom, or leave off the old pipe on the ceiling and the bottom, and replace only the central portion of the riser. Any differences in the replacement of risers and water heating are not different than that described in the first section of this article. The only thing that is necessary to provide, so it is a bypass line to the radiator. It is often not set, and when the apartment is hot, simply overlap the valve on the riser without blocking the coolant flow, not only at home but also in all the apartments of this feed on heat riser. The bypass line is a bridge that allows you to adjust the supply of heat to the radiator, coolant is not blocking traffic to the other floors, it is more expensive in materials, but it is a mandatory requirement. On the cost of the work may affect the transfer of a radiator, then you need to call the private plumbing with a lot of experience, as a replacement of the riser should be done without having a constricted inner diameter of the pipe. This condition makes it possible to evenly circulate the heat on all floors and eliminates failures in heating the entire apartment building.
