Low Water Flow Rate: Warning Signs Low Water Flow Rate: Warning Signs

Usually water flow rate starts to decrease in pressure when minerals and other deposits start to build up inside a pipeline. However, every pipe can develop a different type of bacteria inside it which is the result of the chemical reaction between the minerals in the water and the pipe itself. Hence, here are some warning signs and different causes of low water flow rate which you can easily spot by doing a small inspection.

Copper Pipes

Nowadays copper pipes are becoming very common in our homes since they are very durable, rust-free and particularly good to install in tight places because of their small diameter. However, after some years calcium deposits generally start to build up inside the copper pipes and therefore, the water pressure starts to decrease thoroughly. Thus, if you notice a low flow rate you can solve the problem by running some vinegar through the pipes. The vinegar will eventually soften the calcium deposits making it easier for the water to flow throughout the pipe. Moreover, if the vinegar does not solve the problem, you can use some hydrochloric acid.

Galvanized Pipes

Galvanized pipes are usually used for outdoor piping systems such as in irrigation or in large industries. Even if these pipelines are galvanized from the outside and are anti-rust, corrosion can start to develop inside the pipes. Hence, when the water flows through the pipe, the oxygen in it will start to react with the metal creating corrosion and other rough surface forms which will block the water flow. However, in this case it is recommended to change the pipelines since it can be expensive to get them repaired and you will never bring them back to a perfect condition.

Improper Installation

Improper design or installation can also decrease the water flow rate. Plumbers may have installed pipelines that are too small making it difficult for the water to flow in high pressure. You can notice this problem if there is no water pressure at the water tap. Thus, the problem can be solved by installing new pipelines which have a larger diameter.

Kitchen Drain Pipes

A lot of debris often starts to deposit in the kitchen drain pipes ending up blocking the water from draining down the line. An unbeatable warning sign of this problem is the nasty smell that is caused by this debris. You can use some drain cleaners to solve the problem or otherwise, a less expensive method can be a mixture of vinegar and rock salt. These will eventually dissolve the debris, making way for the water to flow properly.

Shut Off Valves

If you notice a low water flow rate it is practical to first check the shut off valves of the pipelines. Make sure that the valves are not closed or partially open which will radically decrease the water pressure. Hence, open them completely in order to make room for the water to flow through the pipes.


These are some common warning signs of low water flow rate which one can easily spot. However, if the problem gets more complex it is always recommended to refer to a professional plumber service to get the job done.
