Dissatisfaction with the pressure of water in the system is a household problem, concerning everyone, regardless of the place of residence( apartment or separate building) and property rights. Water supply in private houses is organized either from an independent source, or by connection to a central highway.
Let's consider all possible ways to increase the pressure in the circuit, and the reader will determine what it is necessary to do with his home. Moreover, most of the issues are solved without any significant material costs.
Causes of low water pressure in the water pipe
It will not be possible to increase the pressure in the pipes( which should be normal, read here), not knowing what caused the decrease in pressure in the water supply of the private house. That's what you need to start solving the problem. To take into account literally everything is impossible, but there are a number of typical, most frequently encountered "faults" that you should know about.
- Leaks, accidents on the track.
- Reduction of Dy pipes due to foreign deposits on the internal walls of the plumbing sections.
- Clogging of the cleaning filter at the entrance to the private house.
- Defects( failures) of the shut-off valves.
If the water supply of the private house is centralized, the possible reason for the pressure reduction in the system may be in the supplier's poor performance( for example, disconnection of one of the pumps to the substation in order to save electricity / energy, an accident on the route).Before thinking about ways to increase the pressure, you should ask the owners of adjacent buildings whether they are experiencing difficulties with water supply.
If this is a general problem, then first of all you need to "pull at" the public utilities. The basis is the provisions of SNiP No. 2.04.02 of 1984, Government Decree No. 307 of 2006.The minimum pressure on the approach to the private house( for a single-story structure) is 1 bar. If there is a 2nd floor - already 2.4.
What to check first
The author will outline only the algorithm of actions, his vision of how it is easier to solve the problem of increasing the pressure. And what exactly should be done, the reader will understand himself. We proceed from the fact that if the house is connected to a central highway, and there are no complaints against communal utilities - the water is supplied with the proper pressure.
Testing the operation of the pump station
There is nothing complicated, as it contains a pressure gauge that shows the pressure at the entrance to the house. If the head is below the nominal, it is necessary to do an unplanned maintenance of the pumping "economy".As a rule, the most probable cause is the clogging of the deep filter. When the set of equipment is assembled by hand, the task is simplified. The master( he is a master) himself knows all the weak points.
Monitoring the state of the fine filter
Usually, the product is intended to enter the building. Often before it simply "hands do not reach".Even less often the owners pay attention to individual water filters, which must be put on the line of connection to the water supply of each of the household appliances. If the same washing machine does not work well, this does not mean a reduction in pressure in the system.
Checking the pressure at all points of the
You should walk around the house and check how the water from each tap goes. It's one thing when, with the full opening of all the valves, only a weak jet appears from them. The reason is clear - the problem is in the central tube. The site is from the pumping station to the wiring unit through the premises. The case is extremely rare, especially when the installation of the water supply system was not using hardware, but plastic pipes.
Insufficient pressure from only one tap narrows the troubleshooting sector. Firstly, it is necessary to examine the part of the house where the "thread" of the water supply to this valve is going. The previous task is to check the presence of puddles on the floor. Secondly, if everything is OK, disassemble the crane and determine what is wrong. Nothing else can be.
Artificial pressure boosting methods
Activation of an additional pump
The pump is selected individually for each water supply system. A number of its parameters are taken into account: the length of the main line, the cross-section of the pipes, the number of floors in the house and the like. This is a separate topic for consideration. But in terms of recommendations, you can advise such models as the Russian "Comfort", imported "Grundfos", "UNIPUMP".They have shown themselves well in practice, and the feedback of owners of private houses about these pumps is the most favorable.
What to look for when choosing a pump
Price of the product - at the discretion of the reader. From the point of view of the expediency of acquisition, it is necessary to familiarize with three basic characteristics of the pump.
- Productivity( l / min).
- Head( m).
- Power( W).
It only remains to add that such an acquisition is not too burdensome. The cost of household pumps of this class is within 6 900 - 8 450 rubles( depending on characteristics).In principle, cheaper products can also be used, since it is not about pumping water from a well( well) to a house, but only to raise its pressure.
There is a category of products - "booster pumps".For a private house in which there is necessarily some kind of equipment connected to the water supply, such models( despite the attractive price) are not suitable. There are several arguments( for example, when you start the washing machine, you'll have to open and hold in this position all the time while it is running, 1-2 cranes), but believe me, the reader will have problems with the word, and such a device will not last for long.
Partial redesign of the water supply system
In the private sector, "doing everything by yourself" is welcome. This is fully justified, but only not where competent engineering calculations are required. When installing a water supply system someone is oriented to neighbors, for someone "authority" - articles and tips from the Internet.
What can cause a head loss? Even if everything is normal, one of the reasons is the wrong definition of the diameter of the highway. The pipe itself "steals" the pressure. Plus to it - turns on a line, stop valves, fittings, extensions / constrictions and the like.
If no other ways to increase head pressure help, it makes sense to invite a specialist. Perhaps the solution to the problem is in the modernization of the route.
Installing the accumulator
In the case when it was not provided in the self-assembled system, installing and connecting the accumulator can solve the problem of low pressure. As an option - replace with another if the one used was incorrectly selected initially. By the way, the larger the tank volume, the less the pump is in operation. Consequently, the service life is extended.
What is recommended to do
- Determine the range of devices, the operation of which is somehow connected with the water supply system( washing machine, dishwasher, boiler, etc.).
- View their passports and write out the minimum head pressure at which the unit can function normally. It immediately becomes clear the critical value( the lower level) of the water pressure applied to its home. If the control device shows a smaller one, but this does not prevent the tenants, all the same it is worthwhile to take care of the problem of increasing the head. At least, diligent owners are exactly what they should do.
It is worth recalling that one of the reasons for the automatic termination of the manufacturer's warranty for a new technique is a violation of its operating conditions. In this case - inconsistency of the water supply parameters to the nominal working head indicated in the product passport. Those who for some reason do not have the right document at hand, the author suggests.
The minimum values of water pressure( bar) in suitable pipes to devices, in which the equipment can function normally, are:
- Jacuzzi - 4;
- most boilers are 2.5;
- machine( washing) -automatic - 2.
If water flows from the shower head, this is not yet an indicator of sufficient head in the circuit, since the mixer operates at 1.5 bar.
Even if the pressure in the water pipe does not fall below the "critical" level, it is worth considering whether two simultaneously connected "consumers" of water can work normally. For example, a cauldron and a shower. After taking the procedures in the bathroom, the owner can not control how stable the heat generator works. Therefore, checking the pressure, you need to "use" something( open a couple of cranes, for example).Especially in the summer when the heating is off. The data of the measuring device will be more objective.
Weak pressure in the water pipe can "please" the owners initially. This often happens in a new private house, when everything is mounted from scratch. And, as in most cases, it happens, with your own hands. The most likely cause of reduced pressure is the wrong choice of the pump station model or the calculation of its parameters when assembling the equipment from separate components.
In the sector of intensive construction, the "surprises" of electricity / supply are a matter of routine. A lower voltage rating results in a worsening of the pump, hence the pressure drop in the water supply.
Information "to thinking" in abundance. The article is more than detailed, and the author hopes that the reader will certainly draw from it something useful for itself.
