Having low water pressure causes numerous inconveniences such as when you cannot get hot water in the shower or when it takes ages to fill the washing machine. This problem often comes from the plumbing system.

The following quick fixes may solve the problem. Here are 5 things to check if you are experiencing low water pressure:

5 Things to Check If You're Experiencing Low Water Pressure

Inspect the Hot Water Shut Off Valve

Check if all the taps in the house are experiencing low pressure. When the problem lies in the main plumbing system, you will notice it in all of the fixtures. If it is only happening at one point, then that connection could be faulty. For instance, if you’re only experiencing the issue from the hot water faucet, your problem could be centered on the heater. 

In this case, check if the hot water shut off valve has been fully turned on and if there are any signs of a leak in the connection. 

Investigate Leaks

To know if there is a leak in the system, monitor your water bills for any unusual spikes. If nothing changes in your household routine, your monthly water consumption should run at a consistent rate. You should also inspect all the plumbing fixtures for any visible signs of water leaks. For pipes running behind a wall, the leaks may create a stained or moldy patch. 

Check if your neighbors are experiencing the same problem. The leak could be coming from the main supply line. The water company should get it fixed at no charge.

Inspect the Shut Off Valves

There are two water shut off valves in your home. The first one is on the outside, next to the water meter, and it usually belongs to the water company. You will find the second shut off valve in your internal plumbing system. Turning off any of them will cut the water supply in your house. 

Ensure that both of these valves are fully turned on to keep the water flowing at high pressure. To keep it fully opened, turn it completely in a counterclockwise direction. 

Look for Serious Clogs in the Pipes

Clogs happen within the system for many reasons and sediment build-up is among the common culprits. It causes blockages that interrupt the smooth flow of water. Dirt and debris can accumulate inside a storage tank, and finally, find their way into the supply pipes. In such cases, you need to empty and clean your water tank regularly. 

Extensive rust is a common problem in iron pipes, leading to severe clogs. The best option, in this case, would be to switch to rust-free alternatives like PVC. 

Look for Faults in the Pressure Regulator

Usually, the water company keeps the flow at such a high pressure that it may damage your fixtures. To counter the problem, many homeowners install a pressure-reducing valve (PRV). It cuts down the input pressure, lowering the risk of damage to your pipes. If the regulator fails, it can cause a serious drop in the water pressure. 

To check for a failed PRV, monitor the water pressure in all the fixtures at home. 


If you are confident of your DIY basics, you can handle most of these hacks with ease. However, some problems can be extremely sensitive, so you might want to engage a professional plumber.
