Six tips for bathroom and kitchen sanitary installation
Sanitary installation generically combine together, under one “roof”, all pipes and water circuits (hot and cold), heating and sewerage from a house, ensuring proper functionality, congruent to the needs of a modern family.
Designing and choosing the suitable components for a sanitary installation can be a very big challenge for an uninformed person, this is the reason that it is indicated to thoroughly document about this topic or ask a specialist to support the design and especially for its execution.
In addition to designing and sizing the system of the sanitary installation, it is very important to choose the proper pipes for each circuit: hot water, cold water, heating and sewerage, according to their technical specifications and your budget.
The lead and asbestos cement pipes are no longer used for modern residential construction, they are prohibited by EU rules, because they are considered harmful to health. The lead pipes are used now only for discharging the radioactive wastewater, corrosive or contaminated water from factories or laboratories.
Asbestos cement pipes, made of a mixture of cement, asbestos fibres and water, they are found only in the old networks of water adduction and sewer networks built more than 15 years ago and not modernized. Asbestos fibres have a negative impact on health, the danger is deadly if the powder is aspirated into the lungs.
The modern components of sanitary systems in the residential field:
Plastic pipes are among the most popular because of the very affordable price. Instead, they have a lower life and resistance compared to other modern pipes.
The advantages chapter include: initial low cost, low weight, high flexibility, high corrosion resistance. In terms of disadvantages, the plastic pipes have a low resistance to heat and solvents, they do not support high pressures at high temperatures, they do not support mechanical shocks, do not allow cracks and leaks over time.
They have a lifetime of 50 years, which decreases significantly under 25 years, in case that they are regularly under the influence of very high temperatures (for example those used for heating).
Multilayer pipes (PEXAL) are some of the most modern residential components of sanitary systems, managing to combine the advantages of plastic pipes with ones of metal pipes. They have three layers: inner one, from plastic, intermediate one, which is designed to provide rigidity against over pressure and thermal expansion, and outer one from plastic for protection.
PEXAL is an innovative system, recommended for internal distribution networks of hot and cold water and heating circuits, and for air conditioning circuits and under-floor heating. It has a high resistance to corrosion and chemical agents, a reduced linear expansion coefficient and a thermal conductivity of the multilayer pipe of 900 times smaller compared to that copper pipe, which translates into less loss of energy, and high hygiene standards.
PPR pipes (polypropylene) are used for installations of hot and cold water supply, hygiene-sanitary. PPR is a synthetic material of which are manufactured the related pipes and fittings, it can withstand until a temperature of 135 degrees Celsius and it has a lifetime of 50 years. These pipes have a small loss of pressure due to the flexibility and lubrication of the material, which means that they do not allow the accumulation of deposits. They are absolutely harmless in regard to toxicity, under the rules for transport of drinking water, they minimize the possibility of condensation (specific effect of metal installations) and resist to freezing.
Copper pipes are among the oldest components of sanitary systems, being used since antiquity, first by the Egyptians and then by the Romans. Even now, in modern times, they have a lot of advantages. Here are some of them: the spectacular appearance, ease of shaping, facile bending and joining, prevent lime deposits and sediments from the inside and have a long life. These pipes have a high purchase price, reason why they are not so enjoyed and they do not have much popularity among the owners of residential constructions.
Steel pipes are of two kinds, rolled and welded, they have a lifespan of up to 40 years and they are characterized by rigidity, robustness and strength.
The cast iron pipes with admixture of magnesium, which extends the durability and makes them easy to install and shape, have a lifetime record of up to 100 years, and resist excellent to corrosion (ideal for underground installing). Their main disadvantage is that they are heavy.
Other types of pipes: ceramic pipes, special glass pipes.
6 things that you should take into consideration when you are choosing the pipes
- Firstly, the pipes are chose depending on the temperature and the pressure of the water that follows to be carried through. There are pipes for pressure and pipes for drainage, specific for the wastewater discharge system.
- The type of central used and its parameters, because the recommended operating temperature varies from one model to another one. For example, for a central which works on solid fuel and with a heating system with radiators, the best solution, according to experts, is a system with copper pipes. Usually, in the technical specifications of any central, the recommendations about the characteristics of pipes should be written.
- Your budget for planning and installing the sanitary systems of your house.
- Sizing the sanitary system: how many people will serve, what area it works on, the flow of cold water, hot water and drainage that it will transport.
- The advice of the engineer who will design the sanitary system of the house and the technical guidelines of the builder.
- The source of cold water: a centralized system or a connecting system to an underground pit; the pH and the water hardness.
