What causes low water pressures?
Thousands of homeowners regularly have a problem with low water pressure, simply because they do not know what the cause is. If you cannot take a shower and water your lawn at the same time, probably it’s a good time to improve your water pressure and contact a plumbing service to check your water system.
But before contacting a plumber, we suggest you do some quick things that could save you unnecessary expenses to increase your water flow.
Try to find the cause of low water pressure
Check your main water valves – Water valves can be partially closed by accident at your home. An easy and simple check will suffice to make sure they are fully open; this could bring your water pressure back to normal flow.
One of the main causes of low water pressure is often the pressure regulator failing. Not every house has a pressure regulator but if you have one, make sure you check it. It is a tool that adjusts the pressure in your plumbing installation to an optimum level. If it is not working properly, you might experience water pressures that are either too low or too high.
Mineral Deposits in Piping – Mineral deposits are a common problem in older homes, especially those with galvanized iron pipes. Deposits are usually located in horizontal pipes and are caused by hot water that reacts with galvanized metal. If you think your problem could be caused by your old pipes, contact professional plumbers to have your pipes inspected.
And the most interesting is that the vertical pipes suffer less from this. Your built-in filter might also be clogged overtime, it is a good idea to give it a clean and check the pressure again.
If you are living in a building with a plumbing system that is not the most modern one, it is expected to have low pressures at times. The problem of low pressure in the water supply system is directly related to the use of water not only in your apartment but also in neighbours’ apartments. If the water pipe is used by many residents at the same time, it is obvious that this will lead to a decrease in pressure throughout the house. It will be difficult to solve this problem, because for this it will be necessary to draw up a schedule for using the water supply system, which, of course, is inconvenient for most residents.
Tap water pressure is measured in bars. The value has an alternative name – atmospheric unit. Under a pressure of 1 bar water can rise to a height of 10 m. In urban plumbing systems, usually, the pressure is 4-4.5 bar, which is enough to maintain multi-storey buildings. Residents of private houses should be calculating the required water pressure with the help of professional plumbers. If you provide an excessively high pressure in the system, then some sensitive devices may fail or malfunction. Therefore, the pressure in the pipeline should not exceed 6.5 bars.
To have the desired water pressure you also need to know how your appliances operate. For example, for a jacuzzi you need a pressure of 4 bars, for a shower, firefighting systems – 1.5 bars, for a washing machine – 2 bars.
Leaks are the one of main cause of water pressure problems. Fortunately, most leaks can be easily repaired.
If you think that a water leak is responsible for your water pressure problem, then a plumber is your immediate solution to your water pressure problem. You must close all the water faucets inside and outside the house.
If your water pressure is only low in the shower, your showerhead may be clogged. Most showerheads have a filter inside that can get clogged over time resulting in reduced flow of water. It is really simple to fix this one – just remove the shower head and use an old toothbrush to clean the filter.
If you still cannot determine what the cause is, you should contact a professional plumber service. They are experienced enough to find the cause and fix it immediately.
