How to Fix Low Water Pressure of Faucet in the House

For house owners, it is very common to experience low water pressure of  faucet in the house. When you’re in the middle of having fun bathing using the shower, or the tedious but very necessary act of washing the dishes, or washing the car, or watering your flower garden and suddenly the water pressure became weaker and the water pressure of the water pump becomes too low for you to do much in the house.

Usually, you would ask other family members or friends to close the other  faucets in the house. But most of the time, both of you need to use the water as you’re on a tight schedule so you’re forced to deal with low water pressure. So how to fix low water pressure?


Do you know the reason why water pressure of  faucet in the house becomes low?
The reason why your  faucet can suddenly has its pressure weaker is because other  faucets are in use, so the water distribution becomes imbalanced. This condition often happens for houses that uses only one water tank placed on the roof. Water tank on the roof is only effective when it uses Earth’s gravitation to give pressure through the water pumps. During this distribution process, we need the correct plumbing system to get the water running smoothly. The situations described above can happen when the water pumps you use for your  faucet in the house have a small diameter (most commonly, only a half inch), while your house have 4 to 5  faucets.


How to fix low water pressure of  faucet in the house?
To avoid suddenly having low water pressure when you’re using a  faucet in the house, logically, you should close the other  faucet that is being used or were left to run on its own. Half the time, it doesn’t fix the low water pressure; half the time, it works but you’d get the same problem sooner or later. Sometimes, the water even dies out entirely.

So the best way to fix low water pressure of  faucet in the house is to change your pipe installation using the correct plumbing system – this involves a primary, secondary, and tertiary pipelines. For a common one-storey house, it is recommended to use 1” (25 mm), ¾” (20 mm), and ½” (16 mm) pipes.

This is also a given but you’d be surprised how many people don’t bother (or can’t afford) doing it, but you must install clean pipeline. If during the construction dirt, dust, mud, and other things dirtied the pipeline, rinse or wipe them off so the water you’re using will be clean and hygienic.


Below are 3 steps on how to install clean pipes so you can fix low water pressure of faucet in the house:

  1. Primary Pipeline            →   1” (25 mm) vertical pipe from the water tank.
  2. Secondary Pipeline        →   ¾” (20 mm)  horizontal pipe that diverges towards the bathrooms, the kitchen, and the garden.
  3. Tertiary Pipeline            →   ½” (16 mm) pipe that enters the bathrooms, the kitchen, and the garden through water faucets.


For a concrete example of the above abstract explanation, this picture shows the correct pipeline installation, distributing clean water using Westpex pipes. Understanding the pipes’ dimensions will give you a clearer picture of how to fix low water pressure of water faucet in the house.
