Instruction
1. Before starting mounting of water supply system, accurately provide the purposes, that is what has to turn out upon termination of works. Draw the drawing on leaf, on it designate location of units and pipes and also specify what will be used water shutoff and water folding shutoff valves.
2. Define what type of pipes will be used for laying of new water supply. Though there are several versions (plastic, metal and metalplastic), preference is given to plastic pipes now. Their popularity is unsurprising: they it is more reliable than metal plastic pipes, durable, and mounting does not demand special preparation.
3. On the basis of the made drawing project calculate amount of material which is required when mounting new water supply. Define the required quantity of fitting necessary for supply to the boiler, the geyser and other units and also calculate how many it is required running meters of pipes. Get them with small stock.
4. For continuation of works cut off water supply (if mounting of new water supply is carried out in the apartment of the multi-storey building, then water supply needs to be cut off on strut). Agree with the neighbors living on the floor above and on the floor below you concerning insert in their struts. It will give you the chance to replace those sites of pipes which pass through plates, - weak link of water supply of high-rise buildings.
5. After cutoff of water start dismantling of old water pipes. Cut off them the turbine, and then pull out from overlapping "body".
6. On the remained metal pipes of water supply (those parts which you are not going to change) cut thread bar. Then grease thread with fat and wind on it nut. After that reel up the film FUM on thread, wind fitting and press it lock-nut.
7. Make pipe fitting, connecting them to units of water supply.
