Aquatec Pressure Switch Adjustment: 3 Step Process

We know adjusting an Aquatec pressure switch might confuse you. You are thinking about whether you’re doing right or wrong.

What is the correct Aquatec pressure switch adjustment?

The recommended Aquatec pressure switch adjustment is 80 psi. But you can keep it at 60 or 100 according to your need.

To adjust the pressure, you will need a 050” Allen wrench. Simply locate the Allen key at the side of the pump. Sometimes, it can be on top of the motorhead. Rotate the Allen key to change the pressure.

But that doesn’t cover everything on this topic. There is more that you need to know.

What Is The Optimal Pressure For Aquatec Pressure Pumps?

Finding the optimal settings is always the safest route. Aquariums or booster pumps aren’t any exceptions either.

It doesn’t matter whether you’re upgrading Biocube 32 pumps or adjusting Aquatec booster pumps. You have to know some things before you attempt to fix something.

That brings us to the topic. What pressure should someone set at their booster pump?

The answer is pretty technical. Some people like to set the pressure at 100 psi. But it doesn’t mean you have to do the same thing.

The recommended pressure setting for Aquatec pumps is 80 psi. But sometimes Aquatec booster pumps come with a 100 psi setting. That’s when you need to change.

If your house pressure is sometimes low, 80 psi is a great option. Otherwise, 100 psi is pretty fine if you’re okay with it.

But we aren’t here to decide which one to use and which one not to. We will leave that to you. It’s the adjustment that often becomes trouble for aquarists.

Fortunately for you, we’re here to help. We’ve simplified and explained everything steps by step.

How To Adjust An Aquatec Pressure Switch: All You Need To Know

Aquatec pressure pumps are considered one of the best. They’re simple and easy to work with. That’s why they’re praised by many aquarists.

But there are certain things that one might have a hard time understanding. Deflating Anemones can be such an example. But with some knowledge, anything can seem easy.

First, you have to gather some essential tools. Grab them as soon as possible, and you can start fixing them.

Here’s what you’re going to need-

  • 050″ Allen Wrench
  • Clothes

For your convenience, we’ve prepared and explained the entire installation process for you.

Step 1: Turn Off The Water Supply

Water turning off is a fundamental rule when it comes to aquariums. It has to be turned off at all times if you’re fixing something.

It doesn’t matter if leather corals have died or if some tank needs to be adjusted. Since many people try that, we had to give a separate warning about this.

First, turn off the water supply from the source. When that’s done, turn off the valve of the RO storage tank.

If you want to alleviate the pressure, keep the ledge faucet on.

Step 2: Locate the Allen Key

With that out, we can now locate the Allen key. It’s usually on the side where you mount the pump.

If your booster pump is dirty, clean it with a cloth. It’ll be way easier to find the key that way.

Sometimes the Allen key may not be in the usual place. It varies from model to model. That’s why check thoroughly, and you’ll find it easily.

It can also be around the motorhead in some models.

If your pressure pump is old, sometimes it is worth getting a new one.

Step 3: Adjust the Pressure

It’s time to get the Allen wrench of yours. Make sure it’s a size 050” Allen wrench. Otherwise, it may not attach properly.

Since you’ve found the key already, use your Allen wrench on it. Gently rotate clockwise if you’re increasing pressure. Do the opposite to lower the pressure.

Don’t own a 050” Allen wrench? Well, we’ve got your back.

By the way, if you think this is too complex for you, don’t worry. Just call a nearby expert, and they’ll gladly fix this for you.


Question: What are the most common Aquatec pressure switch adjustments?

Answer: There isn’t any specific answer for this. But 30/50 or 40/60 are the most often used values.

It is a question of personal taste. You can set your pressure switch to either 30/50 or 40/60.

Question: Are all pressure switches for wells identical?

Answer: Usually, you’ll find 3 different pressure switches with different ratings. They are 20-40, 30-50, and 40-60 psi switches.

They may look identical to you, but work-wise they aren’t. Constantly update your switch with a similar certified one. It’s super safe and the best option.

Question: Is RO booster helpful for Aquatec pressure switch adjustments?

Answer: RO stands for Reverse Osmosis. This can help you during low pressure.

They usually increase the pressure if the native pressure is below 50 psi. It allows the filtration systems to produce clean water.


We hope this solves all your dilemmas about the Aquatec pressure switch adjustment. That was everything that we could gather on this matter.

One last tip before we go: Remember to keep the pressure in check. Also, if your house pressure is altering the pump pressure, you should investigate further.

It’s a good idea to call a service and get it checked.
