Plumbing in the country and in the country house
Sorry, as always, we prefer to start with simple and trivial recommendations, which you can not pay any attention if the house has a plumber with thirty years of experience and gold hands.
- Engineering plumbing system for all its seeming simplicity - somewhere there is pressure in the supply manifold or an autonomous pumping station operates in a personal well, which means that there must be water in the house, it does not always work.
- A simple, demountable water supply for seasonal water supply does not require the selection and calculation of the diameter of the pipes. Feel free to buy PE80 1/2 and plant on the site economic, irrigation and entertainment networks.
- Your water supply system has a calculated water flow rate, the estimated project costs for the sites and water distribution points. Congratulations, you live in a nice country cottage, which was designed by specialists.
And this third case is the most ridiculous, because professionals who have been counting and installing the water supply network can make mistakes not only in calculating the diameter( working cross-sections) of pipes for the water pipe, but also with the layout of their wiring. Horrible consequences for the water supply system of a private house, economic and household buildings will not happen, but at the right time it can:
- not get the right amount of water in the washing machine;
- refuse the favorite hose for car washing;
- to escape cold water from a heated sauna, etc.
Therefore, for our own peace of mind, we lay out( we come up) a water supply scheme and begin to peek out the internal diameters and other performance characteristics of our bath and laundry plant.
Calculating the diameter of the pipes for the
pipes Our citizens love to invent a bicycle instead of just riding it. All the valid SNiP, GOSTs and technical specifications for pipe products have long been incorporated into charming settlement programs. Ready CAD systems for CAD systems of any purpose( heating, ventilation, sewage, water supply) have been in existence for 40 years. There remains such a product invented by someone to find and enter the necessary data. You will say, for specialists such work is a trifle, but what should I do with a simple countryman in the street? Initial data:
- design( better working) hydraulic pressure of the water supply system that it will be: a well, a well with a submersible pump or a collective main pipeline, does not matter;
- length of the autonomous water distribution system;
- hydraulic resistance - a separate topic;
- the height of the location of the water-injection units and their water consumption.
Add ten more parameters that you will find in building codes and regulations, and you can safely offer to neighbors private plumber services.
Internal diameter of water pipes
We have specially made the hydraulic resistance and stagnant areas of water supply for private houses in a separate paragraph. Suppliers and builders usually do not warn users about the specific inclinations of the products supplied and some of the negligencies allowed in their installation.
- coefficient of friction still has not been canceled: polyethylene in good performance in five to six years will give odds to steel zinc coating of the same internal diameter;
- the number of bends, tees and simply connecting fittings on the water pipe scheme of pipes of any diameter should be kept to a minimum;
- the quality of tap water in pressure water conduits is desirable to be supported by filter stations, otherwise the internal diameter of the pipe will overgrow with silt and mud;
- the ratio of outside and outside pipe diameters for a water pipe absolutely does not affect its operability, if it is made in accordance with technical requirements and certified.
Believe me, the suburban water supply system is a very simple hydraulic structure, provided that you have correctly positioned it in your head and calculated it yourself a little.
