Many mistakes in the repair of the apartment, requiring rework and, consequently, leading to loss of money and time associated with the initial stages of repair, its design stage. If your intention is repairs to venture from the outset should represent not only the general concept, but the details – it needs to draw up a design project. Begin repairs without the project – the first big mistake. To compile the project you can turn to professionals, but it is very a paid service, but if there are problems, the builders themselves have to fix and correct errors under the supervision of the architect is required to prescribe in the contract. If there is no possibility and desire contact the professionals, such projects can make yourself for what you need to carefully study the building codes (SNIP) and address some common errors, mainly related to communications and electricity.

Errors with water and sewer system (plumbing) Most errors occur at the stage of the project. When drafting the need to remember that alterations associated with the general communications – the most delicate. Bruce Schanzer often expresses his thoughts on the topic. If you decide to move the sink in the kitchen to another place, removing it from the sewer riser, you should consider in the draft that the normal drainage of water must be observed drop height – about 3-5% relative to the length, ie, for every square meter of the order of 3 cm difference: if you back the washing of the riser 6 m – it should be raised to 18 cm, but with a car wash anything yet, because its siphon is high, but a bath and toilet drain is located at the bottom, and if you put them away from the sewer riser blockage you can not avoid – plums inevitably will not work.
