Can Water Softener Cause Low Water Pressure

You’ve recently installed a new water softener. However, you’ve noticed a drop in water pressure, so you ask, Can Water Softener Cause Low Water Pressure?

Can Water Softener Cause Low Water Pressure

Yes, a water softener can cause low water pressure. However, most manufacturers insist that as long as the softener remains balanced with the water needs of the households, you shouldn’t experience low water pressure. Nevertheless, the following issues can make the softener reduce the pressure in your home. If your softener is undersized, during regeneration process, blockage of particle filter, blocked resin bed, and presence of particles in the supply line.

Details: Can Water Softener Cause Low Water Pressure

In this section, we’ll cover detailed analysis of how the water softener can cause the low water pressure.

An Undersized Water Softener

The size of the softening unit matters when it comes to household water demand. For example, installing a small water softener, when your household is large, and the water demand is too high can cause low water pressure. The softener will need to generate more frequently. This means it will work overtime. As a result, the excess workload can reduce the effectiveness of the softening unit leading to low water pressure.

Blocked Particle Filter

Water softeners feature a particle filter that helps to catch all particles present in water. Therefore, as water-softening process continues, some particles may accumulate in the filter. Over time, these elements can increase and block the filter. As a result, the water is likely to drop, causing low water pressure.

During Regeneration Process

What normally happens during the regeneration process is the conversion of hard water into soft water. Hard water passes through the water softener via the resin media and ion exchange take place. Sodium (salt) replaces the hard minerals (calcium & magnesium) to give you soft water. The regeneration process can cause low water pressure

Blocked Resin Bed

The resin bed might experience accumulation of particles that escape filtration. As a result, the water may not flow as required since the accumulated particles block water route. Hence, you’ll experience low water pressure.

If The Water Softener Is the Problem, Do The Following

Clean your particle or sediment filter. Regular maintenance of any equipment prolongs its life; the same is true if you own a softener. Ensure you clean or even replace damaged filter to prevent particle accumulation inside the system.

Regular cleaning of the resin bed. Cleaning the resin bed will ensure that no blockage occurs inside the resin bed. You can clean the resin bed using a resin cleaner. You can purchase one online or at your local store.

Allow completion of the regeneration process. If you suspect that the regeneration process is causing the low water pressure, just wait for the completion of the process. The good thing is that, the regeneration process takes little time. Therefore, the water will gain its pressure back.

Invest in a larger water softener. If your household has increased over time, it’s good to invest in a bigger softening system that would meet the demands of your household. Using a smaller softening unit with a large household may not meet your demands. It can cause a reduction in water pressure in your home.

Common Issues That Can Cause Low Water Pressure in Your Home


A leak in the plumbing system can cause sudden drop in your home’s water pressure.  Water that’s meant to come through the tap is instead wasted via the leaking pipes. Therefore, its crucial to handle all leaks immediately to prevent water wastage and damage to the plumbing system.

Clogged Pipes

Clogged pipes can cause a drastic reduction in your water pressure. The main cause of the clogging is small particles like dirt and sand. These particles accumulate over time and eventually block the pipes causing a reduction in the flow of water. Therefore, it’s good to take a routine check on your plumbing system to deal with all emerging issues.

Plumbing Problems

Your plumbing system ensures water reaches the various destinations in your home. However, some older homes have metal pipes. These pipes tend to rust and over time, the metal can leach into the water. Other than that, rust can cause pipe breakage and leakage. With these leaks, you’ll notice a reduction in your water pressure

Defective Pressure Regulator

The job of the pressure regulator is to regulate or control your water pressure levels. However, if you have a defective regulator, you’ll experience problems with your pressure levels. A water pressure regulator main function is to control the amount and pressure of water flowing through the pipes. The regulator ensures that the water flowing through your water system has the right amount of pressure to prevent damage of the plumbing system. Therefore, a faulty regulator can cause a drop in your water pressure. Thus, reduce the amount you get through your taps.

Faulty Faucets

Faulty faucets and taps can limit the pressure of your water. The best approach to dealing with this issue is to replace all the faulty faucets. This way, you will return the water pressure to its normal levels.

Why Is The Water Pressure Low On Some Faucets?

If notice a reduction in pressure in some of the faucets in your home, then it’s highly likely you’re dealing with buildup. The aerator screen on your sink and the showerhead can experience mineral build up and clog causing the low water pressure.

The best solution would be to confirm that mineral build is the issue affecting the pressure. Detach the showerhead, and then turn on the water. If the water flow rate appears normal, just clean the showerhead. However, you can opt to replace it, checkout this article on best rain showerheads and make your choice.

You can also check the aerator screen on your sink. Unscrew it and check for any debris or mineral build up. If you’ve noticed accumulation of the minerals, just Rinse the aerator thoroughly. Alternatively, you can use an old toothbrush to clean it out or decide to replace the aerator with a new one.


Can water softener cause low water pressure? Yes! And we’ve discussed some things that can cause the softening system to reduce the water pressure in your home. The issues include undersized softener, during regeneration process, blockage of particle filter, blocked resin bed, and presence of particles in the supply line. However, the article discusses practical solutions to all these issues.
