Thermal insulation prevents condensation on the pipes, thereby preventing corrosion. Condensation occurs due to high humidity, mainly in the cold riser. In the summer, during the off hot water and hot. A separate theme – replacement of sewer riser. Cast-iron sewer riser with chopped molded parts and to seal joints – not very nice 'gift' new home, also sometimes do not allow for remodeling a bathroom. Usually cast iron risers replace polypropylene. Old is removed completely from floor to ceiling. And the ceiling is a length of about 10 cm, which is then put on a special adapter 'Iron-PP'.
It includes a polypropylene tube and a set of two specially shaped gasket. These adapters let firms VALSIR (Italy), WAVIN (Denmark), MARLEY (Germany). According to the firm's experts' STK INTERIOR ', replacing sewer riser must be done immediately after the installation of standpipes hot and cold water while they are still not filled with water. This will avoid the discharge of large amounts of sewage runoff from the upper floors. Preferred time work – from 10 to 15 hours, this period of low workload sewer riser.
The ideal would be to call at night, in which the riser is almost not loaded, but it unacceptable because of the relevant requirements of the Civil Code as amended. Risers hot and cold water is not recommended walling, as this will make them virtually remontoneprigodnymi. Risers should be possible to place a sanitary closet. The next stage of work – wiring pipes to each point of the water consumption. When wiring in the collector circuit is convenient to use modular or modular combo manifold (with built-in shut-off valves). This allows you to enter into service plumbing items as they are installed, as well as cover the water separately for each device (for example, when it fails), not impacting system operation. Layout of sewer pipes must be performed in compliance with the slope in the direction of the riser as possible to avoid sharp turns. For a washing machine siphon must be installed (water seal) which will eliminate sewer odor penetration into the instrument and the room. Much of today's devices require a connection to not only water but also to electricity. This is a whirlpool tub and shower, washing and dishwasher and more. In such cases, should be used an electric cable for use in wet areas (eg, three-layer insulation NYM) and having the required (specified in instructions for equipment) section. All appliances should be connected through the RCD (residual current device) to the current operation of not more than 30 mA and must be grounded. Just fulfillment of these conditions guarantees your safety and quality performance art for many years.
