5 Things To Do When You Suddenly Lose Water Pressure

Struggling with low water pressure in one or more parts of your plumbing system at home? Check out our extensive guide on how to tackle this problem effectively and find out what might be causing it.

Do you often have to start the day with a feeble shower?

Or wash the pile of dishes in the kitchen sink with a trickling faucet? We understand how frustrating the effects of low water pressure can be.

Moreover, leaving these fixtures unattended for too long can aggravate the problem further and cause substantial damage to your plumbing system. That’s why you shouldn’t delay taking the proper steps if you notice reduced water pressure in one or more parts of the house.

But then again, how will you proceed? How do you identify the real issue? Don’t worry; we’ve compiled this detailed guide to answer all your queries.

So, without further ado, let’s get straight to the deets.

Causes Of Low water Pressure

Water Pressure Meter Residential Home

Several plumbing issues in your home can lead to a sudden drop in water pressure. While some might be specific to a smaller area, such as the bathroom, the problem might originate from the central plumbing system.

That said, here are the five most common issues that can reduce water pressure around the house:

  • Faulty plumbing fixture(s)
  • Blocked/leaking water supply pipes
  • Partially-closed main shut-off valve
  • Faulty water heater
  • Faulty Pressure Reducing Valve (PRV)

Now, you’ll have to figure out the particular issue plaguing your home and proceed to tackle it accordingly.

5 Things To Do When You Suddenly Lose Water Pressure

Now that you know the possible causes for low water pressure, here are a few tips to deal with them:

1. Clean or Replace The Fixtures

Are you noticing the problem only in a particular plumbing faucet or fixture? In that case, it needs immediate attention.

As a result of years of regular use, plumbing fixtures such as aerators develop scale deposits that may hinder normal water flow. The aerator is a small mesh screen placed on the faucet opening to break the water into several streams by filling the air in between.

Scale deposits are caused by the minerals present in the water and might eventually break off. The build-up may then block the water supply. So, you’ll need to inspect such fixtures for scale deposits and remove them wherever necessary. The next step would be to test the water pressure to see any improvement.

If the issue persists, that could mean the fixture itself is faulty. In the case of faucets, the fault may lie in the cartridge that regulates the water flow. It can either get blocked due to excessive mineral build-up or turn defective with age.

As such, you’ll have to replace the cartridge or the faucet itself in case the cartridge isn’t available. Replacing the cartridge will require disassembling and reassembling the faucet, which you might choose to complete all by yourself or by hiring a plumber.

2. Get The Water Supply Pipes Examined

Do all the plumbing fixtures in your kitchen or bathroom have low water pressure? Then the problem might lie with one or more water supply pipes.

In homes with older pipelines, the main pipe feeding a specific area might be blocked or corroded by scale deposits. This issue arises when a chunk of scale or rust breaks off and blocks a narrow portion of the pipe. In such cases, you may have to replace the pipe.

Or else, a leak in the pipe might cause the water to divert from the fixtures, ultimately leading to a reduction in water pressure. You’ll need a pipe leakage repair to solve such an issue.

Either way, you’ll have to hire a plumber to examine the pipes, identify the issue, and address it accordingly. After all, both pipe replacement and intensive repairs are skilled jobs that are best left to professionals.

3. Check The Main Shut-Off Valve

The main shut-off valve of your home controls the water flow throughout the plumbing system. So, if the valve closes partially after someone mistakenly bumps it, the water flow throughout the entire house will drop all of a sudden.

That’s why you’ll need to locate the valve to determine whether it is indeed partially closed. You can find these valves in the basement or interior storage space in most homes. However, homes with water meters installed will have several valves, so it is probably best to call a plumber to locate the main shut-off valve.

After you’ve found the valve, check whether the handle is entirely parallel to the pipe where it’s fixed. If the handle is not appropriately aligned, you may face a decreased water flow running through all the appliances and faucets in your home.

But if the handle is positioned just as it should be, you can rest assured that the culprit of lowered water pressure in your home is somewhere else.

4. Get The Water Heater Serviced

If you’re experiencing reduced water pressure levels only with the water heater in your home, it indicates that there is an issue with the appliance. As such, all the faucets connected to the heater will dispense hot water with low pressure. The best way out of this issue is to reach out to a qualified plumber for assistance.

Also, remember to get the appliance regularly serviced by a trained technician. Keeping your water heater in tip-top condition is the best preventative measure for such issues and others.

5. Get The PRV Examined

A pressure reducing valve (PRV) isn’t used in all residences, but if it’s there in your home, the chances are that it’s malfunctioning and causing reduced water pressure.

The PRV works to regulate the speed and pressure of the water reaching your home from the municipal water supply system. Its function is to ensure that the water entering your home doesn’t cause any damage to the plumbing system.

However, if this valve is faulty or needs replacement, it may drop water pressure throughout the home. You must call in a plumber to get it examined if none of the earlier steps yields substantial results.

On a side note, you should replace a PRV every 12 years to make sure it’s operating the right way.

How To Deal With Low Water Pressure

These are just a few ways to deal with reduced water pressure in your home. We hope you’ll be able to take proper steps the next time such an issue crops up. And if in doubt, reach out to our team. We are happy to assist you.

But before we sign off, here’s one last tip for you; ask your neighbours if they face similar water pressure problems. If the problem is not isolated to a single room, there’s likely an issue with the municipal water supply. Also, maintenance activities on the local water supply system may lead to a drop in water pressure.

In such situations, you should consider reaching out to the municipal authority. Ensure they’re aware of the issue and stay updated on their steps to resolve it.

It’s time to bid goodbye for now, but we’ll be back soon with more informative guides. So, stay tuned!
