The renovation of utilities is one of the most costly and important elements of the renovation of the house. If electricity and water construction is irregular and rigid, subsequent residence is prone to problems. Owing to the covert nature of the utilities renovation works, maintenance and repair will be more problematic。
At the time of the renovation, the owner must not be lazy in the construction of the installation. But someone would say i'm not an expert. How can i be a supervisor? Mimi taught you to remember the eight steps of the water and power renovation
1. Order of construction of utilities:
1 water and power material inspection — 2 bullet line locator marking position — 3 marked slots ready — 4 laid pipe — 5 hydroelectric line — 6 tested pressure test — 7 block treatment — 8 standard dimensions are taken and taken to the bottom。
2. Attention/regulations for utilities
The construction of the retrofitting of the waterways is generally recommended, with cold and hot water coming out at the same level, cold and hot pipes following the right and left heat, laid on the principle of straight and straight, with a reasonable safety of layout。
Water intakes are equipped with indoor head valves, followed by easy maintenance and pre-installation check for leaks, cracks, small cracks, etc。
3 the drainage pipe is designed to be horizontally sloped, to facilitate the use of horizontal differentials to speed up the discharge, and to connect the interface closely to ensure that leakage does not occur。
4 prior to the construction work, strong and weak power, drainage designs are not missing and drawings are available to facilitate modification and adjustment。
Consideration is given to ease of repair, reasonable height of surface installation and reasonable distance of valve installation。
Six cold, hot water pipes, if they're wall-drived, be careful to open the slot, depth > 0. 5-1cm thick, remember the cold water pipes are different
Connections are prohibited within pipelines, which need to be connected for short lengths, and the interfaces are to be placed outside the pipeline to avoid subsequent short circuit accidents。
The installation of electro-thermal water heaters is to be fitted with a site protection device to avoid short circuit failure。
Be aware that powerful and weak power is differentiated by different colours, and that power switches and plugs are separated from wires, with two lines at a distance of 15 cm, avoiding electrical interference and affecting circuit stability。
10 switches, plugs, blackboxes, communication in advance, confirmation of costs and avoidance of disputes
