Replacing water pipes in an apartment: reasons and choosing a priority method

Replacing water pipes in an apartment

Sooner or later, any owner will find a replacement pipe in the apartment! On the walls of the water supply during operation, rust and dirt accumulate, as a result of which the diameter of the hole narrows and the pressure of the water decreases. Similar phenomena are most often observed on pipes with cold water. Most people are familiar with various embarrassments – whether it is barely flowing cold water from a tap, or a poorly filled toilet bowl. And the problem is not the weak pressure, it’s just time to replace the old pipes with new ones.

When to change pipes?

Today, the replacement of plumbing pipes can be carried out as a planned procedure, which is carried out by the services that operate the building or building. However, most of the apartments are currently privatized, and only risers and pipe sections to the shut-off tap are subject to such replacement. The layout inside the apartment living change at their own expense.

Why do the owners decide to replace the pipes in the apartment? Someone just wants to give the apartment pipe wiring a better look, others want to hide the pipes for decoration, and some residents constantly have problems with neighbors because of the old pipes that live on the lower floors.

Wear resistance of various types of pipes

Water supply pipes wear out over many years of operation. The service life of steel products is 30 – 40 years, and now all water pipes that are laid in the bathrooms and bathrooms of houses built in the 60s and 70s require replacement now..

There are situations when it is necessary to change pipes before the expiration of the specified period: this usually happens when the general rules for installing the plumbing system are violated. The preventive replacement of water pipes in prefabricated houses of mass development remains relevant..

In case of a critical pressure drop, it is necessary to replace the pipes, as, most likely, silty deposits have formed in the water supply. Do not postpone this procedure if you have to repair the kitchen or bathroom, or when through corrosion of the pipe has been detected.

Replacing plumbing pipes: what you need to know?

In an apartment sometimes you still have to change the water supply. Do-it-yourself replacement of water pipes is not an easy task! And you need to prepare thoroughly for this event.

Replacing sewer pipes involves dismantling old products and connecting new pipes. The procedure is usually performed before the repair work in the apartment, so that later the sanitary pipes are hidden in the walls and finished with tiles or other material. Pipes can also be laid on the surface of the walls, if it is planned to close them with a box, plumbing equipment or overlapping walls.

And it’s worth starting with a work plan! To do this, you need to redraw the layout of the water supply system, on which the dimensions and problem areas – bends and turns, must be indicated. Then it is recommended to prepare a plan that reflects the replacement of water pipes in the apartment with the designation of new consumers of water or new wiring.

Important! Before starting a procedure such as replacing pipes in the toilet, bathroom and kitchen, it is worth collecting a maximum of information about the methods and methods used. Sometimes the information is contradictory, and it will take time to separate the grain from the chaff!

Pipe selection for replacement

The selection of plumbing pipes is a matter of no less importance than planning. There was a time when soldering of copper pipes was popular, but the replacement of pipes in the bathroom with copper products was not widespread due to the low quality of water and the high cost of the materials themselves.

Replacing sewage pipes with metal plastic did not take root due to frequent accidents and flooding of many apartments. It is more expedient to use metal-plastic pipes for temporary water supply or for laying pipes in hard-to-reach, uncomfortable places, which at the same time require constant access – the connections of metal-plastic pipes should be tightened approximately once a year.

The most common plumbing pipes made of polypropylene. This is due to the ease of installation, attractive price and durability – the manufacturers of such products give a guarantee of up to 50 years on the material. In new buildings, exclusively replacing pipes with polypropylene is practiced.

Why is plastic better??

The most optimal version of the material of sanitary pipes is plastic. But why? The first reason is the operational properties of plastic plumbing. Such products differ for the better from metal in such an indicator as throughput. Replacing pipes with plastic ones will forever forget about clogged water supply and endless corrosion processes.!

This is how plastic pipes look

Plastic pipes are inert to aggressive environments, lightweight, reliable, cheap, due to the presence of special fittings and fasteners are easy to install

Replacing metal pipes with plastic is also beneficial for other reasons. The operational characteristics of the water supply do not suffer at all. But replacing plastic pipes requires less investment.

That’s probably all about replacing water pipes in the apartment. I would like to add in the end that when replacing pipes, all construction and technical standards should be taken into account, as well as the use of high-quality materials. Good luck in hard work!
