The Causes of Low Water Pressure at Home

Low Water Pressure at Home is one of the most frustrating plumbing problem experienced at home, Having good water pressure in your home is an important factor that determines the quality of living you enjoy on a daily basis.

Home water pressure problems may present themselves in different ways, all of which can be quite frustrating. Faucets may take forever to fill a sink or bathtub, or a shower head may not give you that strong spray you want. Your dishwasher or washing machine may take much longer to run a cycle than it should.



Thousands of homeowners suffer from lower water pressure, simply because they don’t know what the cause is. If you can’t take a shower and water your lawn at the same time, now’s the time to know the Cause.



To determine if you have a leak, shut off all your interior and exterior water taps and record the meter. Check back in a couple of hours to see if the reading has changed. If it has increased, you probably have a leak. Leakages in the home will cause damage and can create mold. Walk the home and look for signs of water on the floors, walls, inside closets, under cabinets, in outbuildings such as a garage, shed, or laundry room, or any other area where water lines run through the home.



Corroded plumbing is usually the cause of any issue in this department and it occurs in old houses. Therefore, if you know that yours has a hefty amount of years under its belt, you need to consider replacing all the plumbing. This will be a costly and time consuming project, but it’s best you do it at the first sign of trouble. Steel or galvanized water pipes are supposed to last up to 20 years. Whenever they become corroded, it’s best to have them replaced.



Water lines get clogged with many things but one that is prevalent, especially in galvanized piping, is the buildup of mineral deposits. Over time, these deposits decrease the area inside the water line, which results in low water pressure from the affected faucets. While the use of a plunger can clear many things from a drain, it will have no effect on the mineral buildup. Removing and cleaning the lines is best left to a plumber to prevent damage to the water line. Over time, sand, dirt, and pollutants can buildup in your home’s pipes, especially if a water main fractures. There are a variety of plumbing chemicals that can dissolve the debris and flush them.



mineral build-up can definitely contribute to hair and debris getting caught on something and clogging up your system. Not only can this cause low water pressure, but it the pressure build up behind the clog can cause a pipe to burst. A simple pipe cleaning can solve this problem; however, we recommend steering clear of pouring chemicals down your drains as they may be too harsh and damage your pipes.



Your home’s water flow is controlled by two shut-off valves. One of them pertains to the water meter and can be found on the street side of the meter. While the other valve is on your home side of the meter. Both are usually on a wall near where the line comes in. Although in some cases only city employees have access to the former, you can check to see if it’s sufficiently open.

If either valve is not completely open, this is what is causing the issue with your pressure. As for your personal shut-off valve, it might have remained closed after a round of maintenance, so check it out as well and open it if that’s the case.



If all of the above fails to address low water pressure, you main have a supply line issue. A licensed and experienced water main contractor will know the required size of your water service line. They will also be able to obtain local records to verify the sizing, including the connection size. Frequently homes have add plumbing fixtures added, or been enlarged, making the existing water supply line inadequate.

if you have run out options in your home as to why you may have low water pressure, ask your neighbors if they are experiencing the same thing. Minerals build up and clogs can happen to your area’s water supply system the same way they happen inside your home. The great news is, you will not have to pay for this fix, but the downside is you are also not in control as to when it gets fixed.

If the issue still persists even though you’ve tried everything, your last resort is to call city hall. So you need to let your local representative know that it needs to be fixed as soon as possible.
