PVC pipes for plumbing systems are made from unplasticized polyvinyl chloride. Due to their characteristics, products made from this material can be used in both cold and hot water supply systems.
PVC pipes and fittings for water supply are connected very easily using a special glue.
This article will discuss the advantages of using products made from this polymer, their installation and connection.
Characteristics of plastic water pipes
PVC (as well as metal-plastic or plastic) water pipes are currently the most popular among buyers.
Because it surpasses all other materials in physical and chemical properties. Its positive qualities include:
- resistance of water supply to high temperatures;
- ease of installation;
- affordable price;
- resistance to mechanical damage;
- frost resistance;
- minimal accumulation of deposits on the inner surface of the water supply system;
- the material is non-toxic.
Because polyvinyl chloride is resistant to aggressive environmental conditions, components made from this material are used for laying underground water pipes.
Low coefficient of linear expansion and durability Resistance to UV radiation makes it possible to use PVC, metal-plastic or plastic pipes when laying water pipes in open areas.
For installation of plastic water pipes use Adhesive-sealed fittings are the best choice for apartment buildings, country houses, and small cottages.
Properties of PVC pipes
For the installation of water pipes, grey PVC components are used, which have the following properties:
- resistant to the effects of aggressive chemical substances such as acids or alkalis;
- fireproof (do not provoke spontaneous combustion);
- environmentally friendly and guarantee the impossibility of the development of fungal deposits and the proliferation of harmful microorganisms;
- high throughput;
- easy to install, lightweight, which is very important for installing underground water pipes when the pipe cut diameter is chosen to be large;
- resistant to mechanical damage during transportation to the installation site, unlike heavier materials;
- have increased seismic activity, which makes it possible to use them even in places where the soil is highly mobile.
Blood pressure is an important indicator
From that, What is the planned operating pressure in a plastic pipeline (all PVC)? products are divided into:
- pressure;
- non-pressure;
- for rarefied environments.
For installation of water supply systems, it is recommended to use pressure PVC pipes.
They are widely used for installing water supply networks, as they do not introduce any foreign odor or taste into drinking water and do not change its color.

Installation of water pipes made of PVC components
Adhesive PVC pipes and plumbing systems made from them have already gained great popularity worldwide due to their practicality, and their most important advantage is ease of installation.
They are joined together using a cleaner and a special adhesive that dissolves the thin layer of material at the joint. Once the joining process is complete, a uniform, monolithic seam forms at the joint.
The joint, using glue, is extremely strong, making it possible to bury the system in the ground or wall it up.
Installation takes just minutes; the system assembles like a construction kit. It's crucial to allow the adhesive to dry completely. Under normal weather conditions, this will take about an hour.
It's best to wait and not turn on the water supply prematurely. If the adhesive was used on larger diameter pipes, it may take longer to dry.

Although the installation process is quite simple, it is worth following the following instructions:
- In advance, you need to check the compliance of the diameter of the pipes and fittings by connecting them (without using adhesive) and if the fitting passes freely, then it is suitable;
- To shorten PVC pipe, you can use regular construction scissors. If you need to shorten a larger diameter pipe, it's better to use a rotary cutter or a hacksaw. In either case, hold the tool strictly perpendicular while cutting to ensure a neat cut.
- After cutting, the ends are cleaned using a regular chamfering knife or a file;
- After cutting, the product is cleaned of sawdust, blown through, and the joints are degreased;
- The joints should be additionally cleaned of any possible contaminants using a special primer. It also helps soften the joint material and the fitting itself slightly, preparing them for the adhesive and ensuring a better bond.
- glue is applied in a small amount to the inside of the fitting and the ends of the connecting elements;
- the fitting is inserted into the pipe until it stops;
- To ensure even distribution of the adhesive, it is recommended to slightly rotate all connecting elements;
- Press firmly on the joint for 30 seconds. The entire gluing process should be completed quickly and take no more than a minute;
It is very easy to check the quality of the gluing; the joint should have a smooth scar without excess glue on the surface.
PVC pipes and fittings for adhesive are widely available on the construction market, but it is still recommended to consult with specialists regarding the diameter, connection method, etc. before purchasing.

Connecting element - American
This relatively “young” type of connection was invented and first tested in the USA, which is where its name comes from.
Modern connecting elements are very diverse, but even industry experts have appreciated the ease and speed of installing a pipeline using an American fitting.
An American fitting for metal-plastic pipes will be the best connection method.It is also used for installing systems made of plastic, steel, copper, and polypropylene.
The name "American" is conditional; it covers various connecting elements (couplings, taps, corners), the main thing in their design should be the presence of a union nut.
Experts say the American faucet has a number of clear advantages over other similar components. These include:
- ease of disconnection of the pipeline without rotation of the connecting elements;
- Using an American-style coupling, you can create a detachable connection by using a union nut. With this option, only the nut rotates, which is sometimes crucial;
- A coupling has the same properties, but its use requires a sealant, and the length may not be suitable. Therefore, this type of connection can hardly be considered detachable;
- When installing a union nut, a rubber gasket is used to ensure maximum tightness. This significantly simplifies the connection and speeds up the process.

Types of connection
The union faucet is often used for plumbing installations. Its advantage is that it's quick to install and connects pipes even in hard-to-reach places, requiring little effort even when joining large diameter components.
Repair and maintenance work during operation of the union nut will not be complicated and will not require the use of additional equipment.
A union nut for plastic pipes guarantees a tight and precise connection. Another advantage of this type of connection is the reusability of this fitting during assembly and disassembly of any structure.
This type of fitting is small in size and straight, which allows for quick, secure fastening of the connecting elements without rotating them.
Fittings for pipes of type American screws for metal-plastic and other materials are produced in different variations, such as:
- female threaded fitting;
- external thread fitting:
- welded element with union nut;
- combined connecting element.
The advantages of choosing plastic for a plumbing system are obvious. Those who don't want to procrastinate and want to install a plumbing system quickly choose these components.
Plastic fittings allow for quick and high-quality assembly. They are also indispensable when making turns, branching, or connecting pipes of different diameters.
Fittings for connecting plastic pipes make it possible to assemble design without use locksmith tools in the shortest possible time.

Properly selected components will ensure high-quality assembly of any plumbing system. PVC pipes and fittings are considered the most practical for plumbing systems, as they require no welding.
Installation is simple and requires no special skills. The key is to thoroughly clean the joints and apply the adhesive correctly.
It's also important to purchase high-quality pipes and fittings, so work only with trusted manufacturers who guarantee the quality of their products.
