Tip 1: How to replace the pipes in an apartment



Replacement of pipes in apartment traditionally considered a very complex andrequiring professional skills and knowledge. However, the cost of installing new pipes made by professionals scares many. In fact, the replacement of pipes in the house or apartment is not a task of increased complexity, even for a beginner, especially given the diversity of connective materials and their types that have appeared in modern construction markets.





How to replace the pipes in an apartment


















You will need




  • - calibration sweep;
  • - alcohol level;
  • - Press pliers;
  • - sandpaper;
  • - glue;
  • - soldering iron with replaceable nozzles;
  • - benders for plastic pipes;
  • - scissors-pipe cutter;
  • - threaded fittings;
  • - hacksaw for metal;
  • - knife;
  • primer.




Instructions





1


Make a sketch of the pipeline indicating the placesfastening of pipes and detailing of installed reinforcement. Measure the dimensions of the pipes at the turning points of the track. Determine the number of fittings required for the valves and other fittings.





2


Select New PipesThe most widespread today were metal-plastic Pipes and Pipes from polyvinyl chloride.





3


Make sure of the reliability of the shut-off valves and shut off the water in the apartment.





4


Dismantle the old Pipes.





5


Install new PipesThere are several ways to replace pipes for plastic or plastic. Each of these methods has its advantages and disadvantages.





6


Replacement of pipes using the press fitting method In this methodinstallation of pipes is carried out with the help of special threaded fittings and does not require special equipment and professional knowledge. Cut the piece Pipes the right size, using a hacksaw for metal. The cut must go strictly perpendicular to the axis Pipes. Trim all the burrs with a sharp knife. Loosen the nut on the fitting and insert the pipe into it until it stops. Tighten the nut so tightly that the fitting fittings of the fitting tightly press against the walls Pipes. Use mounting kerchiefs to install the mixer. Lining Pipes to the mixer is done with the use of special angles.





7


The method of "cold welding" Cut the pipe severelyperpendicular to its axis. Treat the outer and inner edges of the cut with sandpaper. Blow the pipe with dry air, wipe off its end with a rag and degrease. Lubricate the fitting and prepared end Pipes special purifier - primer. Apply a thin layer of glue to the pipe and socket of the fitting. Insert the pipe into the socket of the fitting and turn slightly. Hold the parts to be bonded for 30 seconds. With this method of installation, the accuracy of preliminary measurements and installation is very important. glue "grasps" very quickly.





8


Despite the fact that the connections made by thismethod, very durable and qualitative, the use of this welding method is not recommended for non-professionals. The use of "hot" welding requires certain skills and special knowledge.




























Tip 2: How to replace the batteries in the apartment



If you are tired of old peeling Batteries heating, you can replace them. Is it really necessary to call plumbing and take time off work? You can do this, but you can do it yourself in your spare time.





How to replace batteries in an apartment








You will need




  • - New radiators;
  • - air vent;
  • - plugs-plugs;
  • - mounting brackets;
  • - wrench;
  • - flax fiber;
  • - silicone sealant;
  • - Screws.




Instructions





1


Find out what the working pressure is in the heating network. Check the diameters of the discharge and delivery pipes. Take measurements, given the width of the window opening and the height from the floor to the window sills. They will be useful to you when choosing a new radiator. Determine the required power of the new Batteries, taking into account the thermal performance of outdoorwalls, types of window blocks and the size of the room, which must be heated. If you can not calculate these figures yourself, ask for help from professionals. All calculations should be handed over to the authority that issues permits for the replacement of radiators. Wait for a positive reply.





2


Remove the old battery, gently untwistingthreaded connections. Prepare a new radiator, wind the flax fiber for insulation on the threaded connections, cover them with a silicone sealant. Proceed to screw the adapter.





3


Install the air vent. Lubricate the joints again with a silicone sealant.





4


Attach the brackets to which the battery will be attached. Check how tightly they hold. Install a new battery.





5


Install the ball valves on the outlet and supply pipes and connect the new battery to the heating pipe. Do not forget to bleed the air. A new radiator is ready to heat up your house.












Tip 3: How to replace water pipes



Over time, there is a moment when exploitationwater system becomes unsafe: corrosion of metal water pipes, water flows from closed mixers ... It's impossible to delay! It's time to start replacing the water pipes.





How to replace water pipes








You will need




  • - paper;
  • - a pen;
  • - pipes;
  • - fittings;
  • - FUM tape;
  • - bacon;
  • - instruments.




Instructions





1


Before proceeding with the installation of the water main,clearly present the goals, that is, what should happen when the work is completed. Draw a drawing on the sheet, mark the location of the units and pipes on it, and also indicate what type of water and water fittings will be used.





2


Determine which type of pipe will be usedfor laying a new water supply system. Although there are several varieties (plastic, metal and metal-plastic), preference is now given to plastic pipes. Their popularity is not surprising: they are more reliable than metal-plastic pipes, durable, and installation does not require special preparation.





3


Based on the drawing projectCalculate the amount of material that will be needed when installing a new water supply system. Determine the number of fittings required for the boiler, gas column and other units, and calculate how many meters of pipes are needed. Purchase them with a small margin.





4


To continue work, turn off the water (if mountinga new water supply system is carried out in the apartment of a multi-storey building, then it is necessary to disconnect the water from the riser). Agree with the neighbors living on the floor above and on the floor below you, about tipping into their risers. This will give you the opportunity to replace those sections of pipes that pass through the plates, a weak link in the water system of high-rise buildings.





5


After turning off the water, proceed to dismantling the old water pipes. Cut them with a turbine, and then pull out of the "body" overlap.





6


On the remaining metal pipessystems (those parts that you do not intend to change) cut the thread with a die. Then grease the thread with lard and screw the nut on it. After this, wind the FUM tape on the thread, screw the fitting and press it with a lock nut.





7


Mount the pipes, connecting them to the units of the water supply system.
