WSP pH Neutralizer Filter

Not all water filters fix acidic water that eats away at your plumbing. The WSP pH Neutralizer Filter is designed specifically to help reduce low-pH water problems that cause blue-green stains and pinhole leaks in copper pipes. This system balances your water’s pH to protect your pipes and improve water quality.

When past filters didn’t stop stains and leaks, what went wrong?

You might have tried a basic filter or softener that promised better water but still saw blue-green stains around faucets or pinhole leaks in copper pipes. That’s because those systems don’t address water acidity. Acidic water with a low pH literally eats away at copper, causing the problems you see and costly damage over time. Filters that don’t change the pH leave the root cause untouched.

How the control head handles treatment automatically for you

The automatic control head on this system takes care of the service, backwash, and rinse cycles without your input. It uses a reliable NXT2 control valve with a timer to know when to refresh the media inside. This keeps the neutralizing media working effectively as it balances your water’s pH. Because it runs on a timer, it saves you from manual maintenance and helps extend the media’s life.

Calcite media: neutralizing acidity where it counts

Inside the tank, calcite media works by slowly releasing minerals that raise the pH of your water as it passes through. This media is well-suited to treat acidic, low-pH water that causes corrosion. It gently shifts the water’s balance so it’s less corrosive to copper plumbing. The media also helps improve the taste and overall quality of your water.

Durable tank built to last, sized to your home

The system’s pressure vessel is made to last and comes with a lifetime warranty, so you don’t have to worry about tank failure. While we confirm the exact tank size when we size your system, it’s designed to hold enough media to treat the water for a typical single-family home. The size ensures your household water supply is protected without restrictions or frequent regeneration.

Who this filter fits best, and when to consider other options

This filter suits most single-family homes facing acidic water that damages copper pipes. It’s made for whole-house installation on your main water line, providing steady pH neutralization. If your home has very high water demand or larger commercial needs, a bigger system might be necessary. On the other hand, smaller homes or point-of-use treatments could call for a different approach.

What comes with the WSP pH Neutralizer Filter and next steps

Your system ships with a bypass valve included at no extra cost, so your water can keep flowing during service or maintenance. You also get 10 feet of discharge hose for the drain line. The control valve and electronics carry the manufacturer’s warranty terms, while the tank itself has a lifetime warranty. We ship free across the U.S. from Tampa, Florida. Ordering online is simple and backed by Water Softener Plus’s expert sizing help—just call if you want advice before buying.

Who this size is right for

In terms of sizing, this is a whole-house system, plumbed into the main line so every tap in the house is treated. On a typical 1-inch service line that means a single-family home.

We do not publish a fixed capacity for this item, and we would rather size it on your numbers than guess: send us your peak flow rate in gallons per minute and a water test, and we will confirm the right size before you order.
