How to Increase Water Pressure without a Pump

Are you experiencing low water pressure? Unclog the pipe, adjusting valves, elevating water tank height, adjusting or replacing pressure regulators, and removing flow regulators. 

On how to increase water pressure without a pump – you need easy, actionable, yet inexpensive ways to raise the water pressure.

How to Increase Water Pressure without a Pump

Although well water pumps provide great convenience when dealing with low water pressure, they come at a cost.

If you don’t own one, but still want to increase your house water pressure, you need to follow these straightforward steps in this article.

Details: How to Increase Water Pressure without a Pump

You need to identify why you have low water pressure. Measure your home’s water pressure. You can test the water pressure using a pressure gauge

Just connect the gauge to a water spigot, switch on the water, and you’ll see an instant reading. Generally, the pressure should be above 50 psi, but you can adjust it to your preferred level.

Any reading less than 25-30 psi indicates you have low water pressure. However, any pressure setting above 80 psi can wear out the plumbing fixtures.

If you get your water from the local municipality, you should know that they control the water pressure that comes to homes.

Causes of Low Water Pressure

1. Clogged Pipes

Clogged pipes cause blockages that disrupt normal water flow via the pipes.

Disrupting the water flow causes a decrease in water pressure. Therefore, you must regularly inspect your pipes and clear them of any blockage.

Other than that, pipes may experience gradual sediment buildup causing low water pressure. On top of that, the hard mineral buildup can also leave residue inside pipes.

After a while, this residue will pile up and create a block that’s clogs pipes. Thus, you’ll experience low water pressure.

2. Malfunction Valves

Defective valves may also cause low water pressure in homes. Thus, check your valves, and if they are old, replace them immediately.

However, you can adjust it to about 75 psi. Check out this video on how to measure and adjust the water pressure. 

By now, you’re confident and can easily increase your water pressure without a pump. However, before embarking on this task, you must establish the cause of the low water pressure and find a solution.

3. Leakage

Leakages in the plumbing system can cause low water pressure. A leak usually means that there is a crack in one of your pipes.

A toilet that runs continuously can also cause low water pressure. Since most of the water is running nonstop.

4. Issues with the Water Pressure Regulator

Water pressure regulators help to control and stabilize water pressure. It keeps the pressure within the required range.

Therefore, if there is an issue with any of the regulators, the water pressure can fluctuate.

5. Faulty Fixtures

Faulty fixtures like faucets, bathtubs, or showerheads can become clogged, causing low water pressure.

You could clean the aerator or screen to fix the problem. You can also replace the whole fixture.

6. Water Rationing and High Water Demand

Water scarcity or depletion causes water rationing. When water is rationed, you’re likely to experience low pressure.

Most homes have multiple fixtures that generate water simultaneously. This high demand for water can alter the pressure of water in your household.

Someone may run your dishwasher while you’re showering and immediately notice a decrease in pressure in your shower head.

The best approach to solving this issue is by avoiding using all the faucets at once. See Also: Submersible Well Pumps

Increasing Water Pressure with no Pump

1. Replace Clogged Pipes

If they are the cause of low water, pressure replaces them all. You can even choose wider pipes to improve the overall pressure.

2. Replace the Pressure Regulators

The water pressure regulator may have an issue. You can inspect the regulator by adjusting it.

Adjust it to a higher level and observe keenly how it reacts. If you don’t see any change, then your regulator could be faulty.

Therefore, If this is the case, you’ll need to replace the water pressure regulator with a  new one.

However, if you’re uncertain if the problem is the regulator, let the plumber inspect it for you. The information you get from him will determine whether you’ll replace the regulator.

Nevertheless, you can switch off all faucets or taps in your home and check whether the water meter is still running.

If the meter is running, it means there’s a leakage. Go round the house, inspecting for any leaking pipes.

If the task seems daunting, call a plumber to inspect the water system for you.

4. Low-hot water pressure in the shower

So, how do you increase hot water pressure in the shower? First, if you own a water heater, it’s likely that contaminants and sediments have accumulated inside the heater’s tank. Thus, the low pressure.

These heaters last 10-15 years. So, check the age of your heater. If it’s old, replace it. If it’s not old, ensure you wash it regularly.

Other than that, low water pressure in the shower is an issue that disturbs most people. So, How to increase shower pressure? You need to Inspect and fix the clogged shower head.

5. Adjust Valve

The main valve is located near the water meter. This valve controls water flow into pipes and eventually to your taps. You need to find the valve and check if it’s completely opened.
