DIY polypropylene water supply – from choosing pipes to installation

Are you thinking about replacing the water supply system in your house? A polypropylene water supply system installation can be a fantastic do-it-yourself project that enhances the dependability and efficiency of the plumbing in your house. We’ll walk you through every step of selecting the appropriate pipes and fittings and installing them yourself in this guide.

For residential water supply systems, polypropylene (PPR) pipes are growing in popularity because of their longevity, corrosion resistance, and simplicity of installation. PPR pipes are more flexible and lightweight than metal pipes, which makes them easier to work with—especially for do-it-yourselfers.

PPR pipes come in a variety of sizes and colors, and choosing the correct diameter is crucial to ensure adequate water flow throughout your home. It’s important to understand the different types of PPR pipes available before you begin your DIY project.

Installing the pipes and fittings you’ve selected for your project is the next step. Fortunately, even for people with no plumbing experience, installing a polypropylene water supply system is not too difficult. It only takes a few easy steps to finish the installation if you have the proper equipment and a basic understanding of plumbing principles.

Polypropylene or metal -plastic – which is better for water supply

Think about the benefits and drawbacks of these products when selecting materials for the water supply. It is necessary to take into account the technical features and material qualities in order to decide which is better for the water supply: metal-plastic or polypropylene.

This will allow one to rationally conclude that making a choice is preferable.

Metal -plastic

The following conditions should be considered when preparing to use this kind of product:

  1. The inner surface of the metal -plastic pipes is made of stitched food polyethylene, which allows you to transfer drinking water through them.
  2. The next layer consists of an adhesive composition that strengthens the structure.
  3. Aluminum foil serves as a hardening and sealing layer, since its edges during installation are welded by a laser. It also represents oxygen protection for the transmitted fluid.
  4. This is followed by another strengthening adhesive layer.
  5. The outer surface is protected by a thick layer of polyethylene.

This device makes the product extremely robust while keeping it relatively flexible, allowing for the formation of marked networks with any level of complexity. The manufacturer states that a system of this kind has a minimum 50-year service life. Simultaneously, it’s critical to buy top-notch goods from reputable manufacturers that have quality certifications.

However, metal-plastic products have certain drawbacks, which are reflected in the following situations:

  • The temperature limit is not more than 75 degrees, which narrows the scope of their application;
  • The maximum pressure of the water supply network should not exceed 10 atmospheres, otherwise the pipeline can occur;
  • The main disadvantage of metalloplasty water pipelines is the widespread use of threaded joints during installation, the main disadvantage is the need for regular maintenance of the system for detection with the elimination of leaks;
  • Such wiring is not recommended to hide inside the wall so that you do not have to open the surface in search of a possible leak;
  • the need to use sealing materials during the installation of networks.

SUGGESTIONS! It is not recommended to use metal-plastic products to create networks that are concealed inside walls. The wall’s surface will be taken apart once leaks on the threaded connection appear.

Polypropylene pipes

Nonetheless, it’s important to acknowledge polypropylene products’ increasing popularity. The following conditions can be taken into consideration as the cause of this:

  1. In water supply networks, materials do not emit harmful substances.
  2. The operating temperature of the transported fluid can be up to 95 degrees with the possibility of short -term increase to 110. Therefore, polypropylene pipes for hot water supply and heating are more reliable than metal -plastic.

Water supply polypropylene pipe diameters allow Make nets that are between 16 and 110 millimeters in size. In other words, they can be installed on internal or external structures. The following indicators show the homological series of sizes: millimeters: 10, 16, 20, 25, 32, 40, 50, 63, 75, 90, and 110. It is six meters in length as standard.

  1. The maximum pressure of the water supply from polypropylene can be up to 20 atmospheres.
  2. With high -quality installation, fluid leaks or network depressurization do not occur.
  3. Resistance to low temperatures, which allows you to use when the external water supply of an open type. The elasticity of the material compensates for the change in volume even during freezing of water.

However, the primary benefit of items made of this kind of material is that they are much less expensive than items of other kinds.

Polypropylene pipes have certain drawbacks, such as the material’s peculiarity of softening at +140 degrees and simply igniting the product at +170 degrees. They can sag and lengthen considerably when heated.

For polypropylene, the quality of the source material matters. This metric and the products’ dependability determine durability. Regretfully, under home conditions, it is impossible to control the quality.

To help the user with these systems, which is better for a water supply—polypropylene or metal-plastic? Additionally, the decision is based on a number of the previously listed considerations. To put it succinctly, metal-plastic pipes work best for cold water supplies, while polypropylene is best for hot water supplies.

How to choose polypropylene pipes

Plastic pipes are manufactured in accordance with the specifications for polypropylene water supply pipes specified in GOST 52145-2003. The way other plastics are used to make products serves as a guide for his requirements.

Standards for additional components for polypropylene pipelines are regulated here by regulations. If you want to set up a polypropylene water supply on your own, you must read through this standard’s requirements to make sure you meet all the requirements and gather the water in the right way for the network.

When choosing polypropylene for a water supply, you should first consider its markings. It is made up of various conventions. One of them provides information about the manufacturing material and, consequently, its characteristics:

  1. Pipes for the production of which homopolypropylene is used, which has increased strength. It corresponds to the designation of PRN. The main application is for water water supply, as well as ventilation systems.
  2. Another marking is RRV. Such polypropylene pipes are suitable for the installation of warm floors, as well as for the purposes provided for by the previous paragraph.
  3. The most common is the third type. The material for him serves as a random polypropylene sopolymer, which ensures the use of products from such material on heating systems, hot and cold water supply.
  4. A special look that allows them to be used at temperatures about 95 degrees is indicated by PPS.

Which polypropylene pipe is best for the water supply depends on the specific item, the layout of the system, and the developer’s preferences.

Color solutions

First and foremost, this is a factor that draws attention. Pipes made of polypropylene are available in white, gray, green, or black. But he essentially says nothing at all. The sole distinction is that it is meant to be black, which denotes its resistance to intense UV light.

Apart from these classifications, the marking also provides details regarding the product’s size, manufacturer, connection to the ARD (GOST or TU), and operating conditions class.

Polypropylene wiring schemes in the apartment

On the surface, setting up a water supply for an apartment seems straightforward. Each console should receive liquid from the central riser according to the apartment’s water supply plan. To put it simply, this can be a kitchen sink, bathroom sink, laundry sink, or toilet sink.

However, in actuality, a somewhat different image is seen. There are also other water intake points, like the bidet, circular shower, washing machine (check out how to manually connect to the sewage and water supplies), and other plumbing consumers. As a result, the issue of water delivery to multiple locations at once may come up.

Watch the video [SOCIALLOCKER] to see wiring with tees or collectors.

A complex system of tap water consumption is represented by multiple diagrams of its distribution.

Troinic scheme

A central pipe serves as the distribution point from which the challenges are installed into each console via tees. This method has several drawbacks but is the simplest for distributing the fluid within the system.

A decrease in water pressure across different watersheds is one of them. As a result, only system fluid that is left over and might not reach the network’s end does so. In addition, you must shut off the entire water supply system, beginning at the riser, if any console maintenance or repairs are required.

The simplicity of installation and economical material consumption are the only benefits of this scheme.

Collector scheme

The supply of the entire fluid volume to the distribution device known as the collector is one characteristic of such a water distribution scheme.

There are bdows for multiple separate consumption points inside a metal case. They may come in two or ten numbers. Every discharge has a ball crane that lets you turn off the water on the console of your choice.

It is feasible to install more equipment using this connection scheme. Thus, you can add more biological and chemical cleaning filters, ozonators, and other devices to a kitchen supply. Cut off from the main supply, they will only purify the water used for cooking and drinking.

You can only turn off the water at the desired point of water clearance during the repair, without halting the flow of water throughout the system.

Although installing the collector system will require a much greater number of pipes, the costs will enable the use of the most luxurious water supply.

The collector water supply system’s layout must be drawn out and then chalked over the locations where polypropylene pipes of the appropriate sizes are to be installed. It is best to leave particularly intricate wiring schemes to a skilled designer in order to prevent mistakes.

The selection of material for heating and DIS

The choice of quality indicators for this purpose should be made with special consideration given the characteristics of the material. Thermoplasts are susceptible to deformation while operating due to changes in internal pressure and temperature.

As a result, products made of fiberglass or reinforced aluminum are required for these systems. For these products, the only dangerous overheating occurs when the coolant reaches a temperature of more than 140 degrees.

Choosing the Right Pipes 1. Consider the diameter and pressure rating needed for your water supply system.
2. Choose between PEX, CPVC, and PVC pipes based on your specific requirements.
3. Take into account factors like temperature, chemical resistance, and cost.
Planning Your System 1. Create a detailed plan of your water supply system, including the layout and connection points.
2. Measure and mark where the pipes will go, considering any obstacles or obstructions.
3. Ensure you have all the necessary tools and materials before starting.
Installing the Pipes 1. Cut the pipes to the required lengths using a pipe cutter.
2. Attach fittings, valves, and connectors as needed, ensuring they are properly secured.
3. Use appropriate methods to connect the pipes, such as crimping, gluing, or soldering.
Testing and Maintenance 1. Test the system for leaks and proper water flow before covering the pipes.
2. Insulate pipes in cold areas to prevent freezing.
3. Regularly check for leaks and make any necessary repairs.

For homeowners, installing a polypropylene water supply system on their own can be a satisfying project. You can guarantee a dependable and long-lasting water supply for your house by selecting the appropriate pipes and using the right installation procedures.

A few things to think about when choosing polypropylene pipes for your water supply system are material quality, size, and pressure rating. Polypropylene pipes are a great option for do-it-yourself installations because they are lightweight, corrosion-resistant, and simple to handle.

Ensure you have the required tools and equipment before beginning the installation process. This includes fittings, pipe cutters, and an appropriate solvent to weld the pipes together. An effective installation depends on careful planning.

Make sure you adhere to the manufacturer’s instructions when attaching the pipes and fittings during the installation process. Your water supply system’s integrity and the prevention of leaks depend on properly welded joints. To prevent any future problems, take your time and proofread your work twice.

Make sure you give your homemade polypropylene water supply system a thorough test after installation to look for any leaks or problems. Examine all of the joints and connections, and adjust as needed. Your polypropylene water supply system can last for many years if it is installed and maintained correctly.
