In many now still there are old metal pipes which are operated decades and often demand replacement. Many people have already faced rust problems in pipes, congestions of unpleasantly smelling precipitation and need of frequent cleaning of pipes. Quite often from tapping cocks badly smells of the sewerage because pipes are strongly polluted. Old pipes need to be changed, but on what? Naturally, at first it is necessary to choose pipes, and then to be engaged in replacement.
Instruction
1. It is possible to choose metal pipes, of course. Here the choice is rather big. But it is necessary to consider that any metal, even corrosion-proof, from this rust is not insured. Therefore it is better to choose water pipes from PVC. They have features.
2. Polyvinylchloride (plastic) pipes every day gain popularity. It and no wonder, plastic pipes are suitable for use in the most various living conditions. So pipes from PVC are equally good as as channels for withdrawal of sewer waste waters, and as highways for supply of water and gas to houses and apartments. Anyway, such pipes very long serve.
3. The second advantage of plastic pipes – resistance to corrosion. Such pipes will not rust and will not decay, being established even in the crude basement or in the bathroom.
4. If on plastic pipes dirty water flows, the raid on their walls is practically not formed because plastic surface very smooth and too slippery for dirt.
5. It is also worth mentioning about the cost of pipes from PVC. It is much less, than at metal pipes. For the simple reason – process of production of plastic many times less costly, than process of extraction of metal and its melting.
6. It is also very simple to replace plastic pipes. As you see, at pipes from polyvinylchloride set of advantages. However, It is necessary to tell several words in protection of metal pipes. They transfer frost better and therefore they are more often used on the street in gazo- and water supply systems. Plastic pipes from frost and freezing of the soil can burst, and here such opportunity does not threaten metal pipes.
7. We sum up the results. If you choose pipes, be defined for what purposes they are necessary to you. You are going to replace with new pipes old and rusty? Then safely buy polyvinylchloride pipes. If it is required to replace or lay the pipeline outdoors, then it is necessary to choose galvanized metal pipes. This covering will increase their resistance to corrosion.
