How to increase water pressure outside spigot

How to increase water pressure outside spigot. Water pressure affects the performance of any washing activity, such as washing something in the kitchen sink, watering the plants in the lawn, or cleaning a wide area using an outside spigot.

If the cleaning item or area is not broad, then even a bucket will be enough for it, but what if you are determined for an enormous cleaning task, but the outer faucet has low pressure?

If you are dealing with the same issue and want to save time while doing regular tasks, you may consider increasing the water pressure outside the spigot.

In the following article, you will know the reasons for low pressure and the helpful tactics to efficiently increase the outside spigot water pressure.

A Guide How to increase water pressure outside spigot

If you find that your house’s outside spigot has insufficient pressure, then different reasons may create the issue of low pressure.

You may pay focus to some factors, which include the inspection of the spigot, and checking build-up in the line drives to the faucet, as the water contains deposits in most areas that may trigger the pipe to get clogged.Increase Water Pressure Outside Spigot

If you have attached a hose, don’t forget to review it too. You may also need to notice that the water pressure is low at a specific time, or there is no fluctuation in the water pressure, whether day or night.

You may also examine the main valve as well as the pressure regulator. The guidelines mentioned below will let you know the leading causes of low-pressure outside spigots.

Reasons For Low Water Pressure

Faulty Spigot

If you are facing the issue of low water pressure at the outside faucet, then you need to start inspection from the faucet. Different things can cause your faucet to lessen the pressure.

The first thing you may check is the leakage issue; if the faucet leaks, it may lead to low pressure. You may also check the faucet is not damaged; if it’s broken, efficient pressure will only become your dream.Faulty Spigot

Another reason that may become a culprit to your faucet is build-up. Usually, the minerals can block the faucet as well as block the way of water that drops the pressure consequently.

Unfasten the tap, remove the clog or make a replacement if it’s damaged.

Inspect Water Pressure Periodically

It might be possible that there is not an issue with your outer spigot or the lines. The root cause may be the water demand at a specific time, leading the water pressure to lower.

So, to inspect the issue accurately, you need to inspect the water pressure at different times. If the water pressure is low at some specific time morning and evening, then the water demand makes a low pressure.

Problematic Attached Hose

If you have attached a hose with the spigot offering low water pressure, then it might be possible that the faucet is not the culprit. You need to inspect the hose to see if it’s leaky, bent, knotted, or clogged.

If you find anything repairable, fix or replace it to resolve the issue. You should also consider that the hose attached to the insert new one contains efficient spray pressure. Using a short plus more comprehensive hose would be better for better pressure.

Inspect the Main Water Valve

Another issue that might happen unintentionally by someone in the home without your knowledge is not fully opening the valve. To find the exact issue, you need to locate the main water valve of your home.

But there is another thing that you may notice if there is an issue with the water valve, then there is a chance of having low pressure in the other water line of the house.

But while finding out the reason for the low water pressure of your out spigot, you can’t skip factor, so it would be better to check the valve is open entirely and secondly ensure it is not weary.

Check the Water Pressure Regulator

If you are facing the issue of low water pressure of the outside faucet, the pressure regulator might be the culprit if it’s not adjusted accurately.

It is usually situated nearby the stopcock. So, to see if everything is alright with the regulator, it would be better to check the water pressure using a pressure gauge closer to the regulator.

A water pressure between 40 to 60 PSI indicates no issue, while a lower than 30 is considered as low water pressure. You may adjust the regulator if you have an adjustable one.

Helpful TIPS To Rise Water Pressure of Outer Spigot

In the previous section, you may know the different reasons that may lower the water pressure. If you find any of the reasons, fix them. Moreover, we have some helpful tips for increasing the outer spigot’s water pressure.

Before starting anything, it would be better to measure the water pressure of the water supply using the pressure gauge. If it’s 20 PSI, you need to take action to fix it. So here you go.

Placement of a Water Pump

The following method will able you to maximize the water pressure of your entire home or only if you want to increase the outer spigot water pressure.

You may pay some attention to placing a water pump for any purpose, even if it’s the whole house or just the outer spigot. A variety of pumps are available for this purpose, but you may also consider the regular pump.

You may install the pump in the middle of the spigot and the hose. Maximum pumps contain a pressure regulator to adjust the water pressure of your desire.

Outer Spigot Pipes Modification

You might know or not, but the pipes that are wider and shorter in size are more suitable than the long and narrow one. After research, we come to know a specific difference at different dimensions.

A 3/4 pipe with a length of 100ft drops the water pressure up to 2PSI and a further 2PSI per length.
A 5/8 pipe drops 4PSI per 100ft and a 1/2 decrease in the water pressure by almost 13PSI.

So, the following content indicates a noticeable difference depending on the pipe size and length. Always try to use shorter routes if you want the desired water pressure.

Here we have another estimation below with a shorter pipe experiment.

Suppose you have a water pressure of 30PSI at the start going towards the outer spigot. A 1/2 pipe with a length of 100ft drops the water pressure up to 17PSI when it comes to the hose.

If you replace the 1/2 pipe with 3/4 and shorten the length from 100 ft to 50ft, it will get the 29PSI pressure after reaching the hose. You can see the difference that comes with the size and length of the pipe.


In the following article, you may know the reasons for the low water pressure of your outer spigot, which may help you inspect the issue and increase the pressure by eliminating them.

You may also learn how to increase the water pressure outside the spigot by using valuable tips. Calling a pro would be best if you are feeling nervous while tackling the plumbing tasks like installing something.
