In daily water use, the flowers are soft, the tap flow is weak, and even the water heater is not properly activated ... In everyday life, many people encounter such terrible things, and the first thing they think is that..
"is there a water problem?"
Low domestic water pressure is not necessarily a problem at the end of the water supply, and more often is caused by congestion, aging or other glitch within the home or the community。
01
What's normal water pressure like
First of all, a criterion should be defined to avoid the perception of low water pressure。
The normal range of domestic water pressure is from 0. 15 to 0. 35 mpa, or, in short, from 1 to 2 metres of current energy, and the dynamic water pressure following the opening of the tap cannot be below 0. 05 mpa, below which the water use is not good。
What we're saying on a daily basis is that there's not enough momentum for the current. Either the water plant or the secondary water supply is deficient, resulting in insufficient source power, or the pipeline failure or congestion, leading to too much resistance during the transmission process. In both cases, water pressure will naturally fall。
02
In a few cases, regional water pressure decreases
If the water pressure of the neighbours is low, the probability is that the water supply will be secondary to the water plant or sub-district. This is mostly a regional problem, not related to individuals, and there are three main possibilities for such large-scale water pressure。
1. Water-grabbing during peak periods: early and evening cooking and bathing hours, surges in water consumption throughout the city and overloading of water from water plants will result in temporary reduction of regional water pressure and recovery after peak periods。
2. Water plant or pumping station failure: water plant water pump unit, control system failure; or second-time water pumping ageing and shutdown of the water supply in the subsector, which directly leads to inadequate pressure on water supply, especially in the most visible of high-level households。
3. The problem of municipal networks: the ageing of the water supply networks in old urban areas, the small size of the pipes, or the presence of gas barriers within the networks, can also lead to a decrease in the water pressure at the end, but this is a regional issue that cannot be solved by individuals。
03
Most of the cases: pipe blockage at home
If the water pressure is low only in one's own home, it is basically a breakdown of the household pipes, which is also the most common cause, which is generally self-solved, while the most common failures are three:
1. Gold blockage: water taps, flowers and filters are the easiest to block, especially in areas with hard water quality, where mud and mud pile up in the net, blocking water passages, which appear to be low water pressure and are localized。
2. Indoor piping congestion: mudslides at the time of renovation, long mosses from plastic plumes and metal chips from the corrosion of zinc plating steel pipes will slowly accumulate in the inner walls of the piping, reduce water flow, increase resistance and naturally decrease water pressure。
3. Pipeline hazard: too many water pipes turn to bends, too few pipes, or there are hidden leaks, which cause water pressure to run low at the end, most of which occurs in renovated houses。
04
Solving the problem: 3-step self-checking + solutions
In the case of low water pressure, 80 per cent of the problem can be solved without having to ask the maintenance staff to follow the next steps。
Step 1: fast-track determination of the scope of the problem
Inquiries about the water pressure of a neighbour's household, if the water pressure is low, can be directed directly to the property or water plant, and secondary water supply problems can be checked; if only one's own house is low and the whole house is under water, focus on indoor pipes; and if only one of the taps is low, the probability is a blockage of hardware。
Step 2: self-cleaning, addressing simple congestion
In the case of a faucet with low water pressure, a filter can be removed, a tap and flowers can be removed, 10 minutes immersed with white vinegar, clean up the water and sand, most of which will return to normal; if a water tank is available in the home, regular clean-up can avoid as much as possible sedimentation congestion。
Step three: dealing with symptoms and solving complex problems
Self-cleaning is ineffective and the following can be tried。
If you are a high-level household, you can contact the property and repair the water pump twice; if you suspect that the pipe is blocked or leaky, you can close the main valve, see if the water table is still moving, and if you are still moving, indicate that there are leaks in the pipeline, and professional teachers are required to test the maintenance and replacement of the pipe; if there is chronic low water pressure in the household, you can install an booster pump after the water table, suitable for water but under pressure in the pipe。
05
At the end
Finally, we would like to remind you that low water pressure at home does not have to be attributed to the water supply end at first. In fact, 90 per cent of household water pressure problems, the root causes of which are blocked with piped or hardware, and a few minutes of simple self-censorship and clean-up, can solve most of the water pressure problems。
If the whole building and the entire sub-district are under-pressured in a regional situation, or if it is not resolved after an investigation, problems may arise with the water plant or secondary water supply, which can be handled in contact with the water plant or the property。
It is hoped that today's little knowledge will help us not to go around the corner and deal easily with the water pressure problems in our homes。
