Why Does My Moen Faucet Have Low Water Pressure?

I’ve been there! Wondering why does my Moen faucet have low water pressure and how can I get rid of this annoying problem.

After looking here and there on the internet, a few things that I found out were quite helpful. I also figured out how poor maintenance practices can contribute to reducing the water flow over time usage. I’ll share about those in some other guide in the near future.

Today I want to discuss how do you fix a low water pressure on a Moen faucet.

To sum up, you can fix the low water pressure issues of the Moen faucet by replacing the aerator, cartridge, and other water pressure concerned parts that could be faulty. Sometimes only cleaning these components may be enough.

Let’s talk more about the whole thing in detail below!

Reasons for a Moen Faucet to Have Low Water Pressure and Ways to Fix It

Before I head towards the most common causes behind the low water pressure of Moen Faucet, there’s something I want you to check.

Make sure that there’s nothing wrong with the water supply pressure of the entire house. The issue may lie somewhere else, which is causing poor pressure on the faucet.

Possible scenarios could be –

If none of this is the case, then I guess you are right, and there’s some problem with the Moen Faucet that needs fixing.

Make Sure the Water Valves Are Fully Open

You will find water valves right beneath the kitchen sink. If these valves are not completely open, then the water won’t be able to flow at its best pressure.

And that’s why you need to check it. Make sure the valves are fully rotated in a counterclockwise manner.

It is also possible that the valves are leaking. In that case, you need help from a plumber to fix it. Other parts can cause Moen faucet leaking problems.

These can also lead to reducing the water pressure of the faucet. Another thing to check is the water supply line. If it’s kinked or crimped, then this could also make the pressure low.

Clogged or Dirty Aerator

Some new Moen faucets come with a small disc that looks like a screen. It stays on the faucet’s tip. This is the aerator of the faucet. This part is responsible for reducing water use and saving utensil bills.

Sometimes the aerator catches debris and traps build-up that can contribute to reducing the water pressure. In that case, removing the aerator and dislodging all that mess can help.

Moen suggests that one removes the aerator from the faucet by unscrewing it. This simply needs to be rotated counterclockwise.

For pull-down faucets, the aerator needs to be out from the collar or spray head using locking pliers and a screwdriver. The location will vary depending on which model Moen Faucet you own.

Now there’s also a plastic perforated disk called a flow restrictor that you should find in the cavity. Leaving this part can also help with improving the flow.

But how do you remove the flow restrictor on a Moen faucet?

Well, it’s fairly simple! To remove the flow restrictor on a Moen faucet, just access the cavity and use a suitable tool to take it out.

A clogged aerator often causes problematic water flow in the faucet. But the actual culprit behind that clog can be many things.

Sediments may block the aerator over time. This can even make the spray unusable. Such clogs can also take place due to hard water.

Clogged Cartridge Can Make Water Pressure Low

After making sure that the aerator is free from any clogs if the pressure still stays low, then check the cartridge.

Sediments might have blocked the cartridge, and hence the flow is low. You should consider getting a new cartridge if this is the case. You see, even after cleaning the cartridge, some sediments could have already worn it out.

So, the problem will quite likely appear again. After replacing the cartridge, don’t forget to flush and clean the valve. This should help in increasing the water pressure of the faucet.

A Few Things that Can Cause Low Pressure

Get a Water Pressure Booster Pump to Increase the Water Flow

I have improved the water flow of the faucet by trying a solution as I did not want to deal with this same issue repeatedly.

How do I increase the water flow in my Moen faucet? By taking the help of a water pressure booster pump.

Yes, there’s a tool that can boost the flow of water as soon as it reaches your home. This helps when the water supply line travels through a great distance or even uphill from the water source.

The pressure often is disrupted due to such traveling. And the pump can revive the flow quite generously.

The Red Lion 602207 Premium Shallow Pump is a reasonable option with promising features to help with low water pressure issues. One thing I would mention though is that it does increase the electricity bills.

Wrapping Up

Why does my Moen faucet have low water pressure? I hope you have the answers now. Go ahead and give these fixes a try, and hopefully, the problem will be gone.

It is important to occasionally clean and lubricate the faucet parts to make sure it keeps working without problems. Damaged parts need to be gone, or else such troubles will keep on appearing.

That’s all for today! See you in my next guide soon.
