Causes For Low Water Pressure In Your Home 

1. Faulty Water Pressure Regulator

If you are experiencing low water pressure, the first thing you must do is get your pressure regulator checked, as chances are it may not be working properly. This is how to verify it –

  • Take a basic water pressure gauge.
  • Fasten it to the fixture, or plug it into your outdoor hose.
  • Turn on the water, and the gauge should accurately display the pressure.

If the gauge shows lower pressure, know that the regulator is broken if the pressure regulator indicates a greater pressure but the gauge shows a significantly lower pressure.

2. Clogged/Congested Pipes

Given how frequently pipes clog, you have undoubtedly considered this first. Minerals and rust usually deposit in the pipes, causing the water pressure to decrease. This issue is mostly common with galvanized pipes. Moroever, materials like hair, soap scum, and grease accumulate in the pipes. Thus, restricting the water flow.

Debris accumulated in the pipes can also cause the pipes to weaken and break under excessive pressure from drain obstructions.

Also, clogged pipes do not allow the water to heat properly. So, if you are wondering what’s wrong with your water heater, consider calling a water heater repair. They will identify and fix the issue.

3. Corroded Pipes

Old homes in San Jose mostly have galvanized pipes. These pipes are mostly at risk of getting corroded – which might be the major cause of low water pressure. 

Consider the age of the pipes. Also, consider the quality of the material. For example – galvanized steel pipes have an average life span of 20 to 50 years. Meanwhile, materials like brass, iron, and copper may last up to five decades or longer.

The best plumbers recommend replacing your galvanized steel pipes with copper, brass, or iron – they are long-lasting and can save you thousands of dollars.

4. Water Meter Valve Is Half Open

Indeed, there is yet another large valve that is equally crucial. But there’s a catch – this one is difficult to get to, particularly if it’s hidden underground or positioned on an exterior wall

Although the water meter valve is technically business property, they keep it hidden from homeowners’ view to prevent any problems. So, if you have recently had plumbing work done – chances are the plumbing services  have left the valve half open. Thus, causing low water pressure.

5. Clogged Aerators

Another major reason for low water pressure is clogged aerators. They are small attachments that act at the tips of faucets to regulate the water flow and mix it with air to reduce splashing.

Over time, mineral deposits and debris can build up in the aerator. Thus, blocking the flow of water. Experts for drain cleaning can help you clean your aerators.

6 Ways To Fix Low Water Pressure in Your Home

1. Fix Corroded Pipes

Some people swear by vinegar and say it rapidly eliminates rusting. These are only short-term fixes, though, so you might want to think about getting the pipes fixed correctly.

This involves removing the rusted components and installing new ones in their place. Although this procedure often costs hundreds of dollars, keep in mind that this is an investment in your comfort and safety over the long run.

2. Check Your Faulty Water Meter

Replacing the defective pressure regulator entirely is the only solution available. Don’t worry, it won’t break the bank.

To ensure you have the best one – make an appointment with plumbers. They will help you get the best quality regulator and install them, as well!

3. Clean Your Drains

The precise location of the obstruction cannot be determined logically. For this reason, it would be preferable to seek assistance from a qualified plumber.

Note: Use vinegar and baking soda to clear your clogs – they work wonders with minor clogging. 

Local plumbers advise avoiding using chemicals to clear pipe congestion. Your health may suffer if you put potentially hazardous liquids or solutions into the pipes that supply water to your home.

Give skilled plumbers in Sacramento a call and let them handle this for you.

4. Open The Main Water Valve

Your house definitely has a main water valve – located near the meter. It controls the water flow in your home. So the first thing you should do is – run to your water meter and see if the valve is open. If it is half shut – open it – and you will have a good water flow.

Usually, the valve is turned off accidentally after maintenance work. The valve is easy to turn on – hence, there is no need to call a plumber. But, just in case the valve is jammed and won’t turn on easily – don’t try it yourself. Call professional plumbers for help.

5. Replace the Regulator

If you have a public water supply, then you have a water regulator. It ensures that water does not rush through the pipes and cause water hammering. But when the regulator goes bad – it causes a restricted water supply. 

6. Install a Constant Pressure System

Replace your standard pressure tank and switch with a constant pressure system. This ensures stable water pressure all across your faucet. Constant pressure will regulate the water pressure depending on the demand for water. If the water demand goes up, the pump speed increases. However, as the demand goes down, the pump speed decreases.

Though it might seem like an additional expense, it is an investment that will efficiently allow the maintenance of the water flow.

Takeaway

Did you know – “US homes utilize 300 gallons (around 1350 liters) of water a day on average“? We are talking about – preparing a meal, getting a shower, and drinking some water.

Currently, most home appliances operate at 50 PSI, and a safe water pressure range is 45 to 50 PSI. When the pressure falls below 35, you’ll be able to feel it right away if you’re used to it. Make sure you thoroughly inspect your house before setting off the alarm and contacting the local authorities.

You can bet on clogs, leaking pipes, or fittings as being the major causes of low water pressure. So, while you are on your own to check the pipes and fix them – be sure to call experienced plumbers in San Jose. They are equipped with advanced technologies and equipment to check and fix the problem causing limited water flow.

Sometimes, water heaters can also cause low water pressure, so we advise you to go for water heater repair in San Jose if required.

It is advisable that homeowners must do a 16-point plumbing inspection annually. This will prevent any plumbing issues and unforeseen issues.
