CHEAP CRAP, FILTER HUSINGSCRACK AFTER 3+ YEARS.

"This product is cheap and poorly made. I wish I never bought it. After only 3+ years, I was awaken this morning by a neighbor who saw water flowing out of my garage. The cheap blue housing cracked and I had 3 inches of water in my garage. Their lame support persons wants you to jump through hoops showing pictures and receipts, but it doesn't matter as they only warranty for one year. WTF? These greedy clowns don't even sell the housing replacements, only a single stage filter with extra hardware you don't with and added cost for being a customer. This company is rotten to the core. . . Will find alternate housing."

— Phil (1/5)

Works better than expected !

"The whole home water filtration system turned the worst water into the best water. Installation wasn’t too bad either. Recommending these systems to all my friends and family."

— Devin D. (5/5)

Difficulty replacing leaking housing

"I loved my whole house system until the housing began to have pin hole leaks. I tried to get replacement housing and have had multiple conversations with at least two different Expresswater personnel and sent photos and details multiple times. I have agreed to purchase and was told I had to go to this WaterExpress website and sent all info in again. Still no assistance on correct housing. I have been without my house filter over 3 months and considering purchase of a entire new system. I am not impressed with this customer service so looking elsewhere. My system is barely 5 years old. I am so disappointed in both the lack of availability of housing only replacements and poor customer service!"

— Lori H. (1/5)

Best.

"I research for a month and I ran into this express water. Ultimate whole house filter system. I installed it myself had zero problems all the gauges work the water feels great after a shower. I’m on Citi water, but seen a difference immediately my only regret was not buying this one sooner. I used pex pipe. Took me the whole day to install it because I’m a perfectionist. I don’t normally leave reviews, but this one was worthy total cost with extra filters thousand bucks."

Expect Excellence

"The Ultimate System has been an absolute game-changer for our home. Living in an area with heavy sediment, hard water, and elevated metals, we needed a filtration system that could handle it all—and this one has exceeded our expectations. Since installing the system, the hard water stains inside our stainless steel dishwasher have virtually disappeared, and our dishes come out spotless. We also tested our water after installation, and the results were outstanding—everything we were concerned about was effectively removed. To maximize filter life, we added a spin-down filter and a sediment filter ahead of the Ultimate System. Even with our challenging water conditions and a household of six (including four boys ranging in age from 5 to 24, so our water usage is substantial), the filters are lasting an impressive 10 to 11 months. I’ve installed several filtration systems from different brands for family members over the years, and this is by far the best. The build quality is excellent, the performance is exceptional, and the price is very competitive. I was so impressed with this system that I purchased one for another family member. Although that unit arrived damaged through a third-party seller, that experience does not reflect on Express Water or the quality of their products. Express Water has truly delivered a top-tier filtration system—great quality, great value, and, most importantly, great water. I highly recommend it. My hat is off to the team at Express Water for creating such an outstanding product."

— George H. (5/5)

Great water so far

"The unit arrived quickly and installation was smooth and easily preformed by our plumber. Very satisfied with everything. Very good product and reasonably priced."

— Paula Y. (5/5)

I should have done this a lot sooner.

"My community shares a common well and tanks and it's been pretty bad. There isn't any treatment (aside from chlorine) from the tanks to our house. I have had to replace many appliances because of the poor quality of the water in the past and I should put this filter system in sooner. I installed it about a month ago (01/26) and I am overwhelmed at the difference. I drink it now, use it for cooking pasta (never used it cook before), and I cannot wait for my swamp cooler and my garden. If you're thinking about this, I recommend it."

— Clifford S. (5/5)

Very nice system

"I was pleasantly surprised by the build quality--quite robust. The sediment filter has been capturing quite a few little chunks and a fair amount of "haze" that I didn't know was in our water."

— Chris L. (5/5)

DLM

"System arrived in good condition and was easy to install. I had to reverse the inlet which had easy to follow instructions. However, a torque setting or number of turns on the pressure gauges would have prevented me from over tightening which prevented two of the gauges from working. After calling about the problem, the tech provided instructions to back off the gauges one turn which solved the problem. So far, system is working great."

— David M. (5/5)

Second home, second system

"These systems are a no-brainer. They’re more affordable than many others and work great. Customer service is good, too!"

— Thomas R. (5/5)

Q&A

How do I read the gauges and how do I know when to change them?
Dear Craig, To read the gauges and know when to replace your filters, follow these guidelines: Normal Pressure Drop: After installation or new filter replacement, expect a pressure drop of 3-5 psi. For example, if your house's incoming pressure is 40 psi, it may drop to 35-37 psi after passing through the filtration system. Filter Replacement Timing: Replace all three Whole House Filters every 6 months to 1 year under normal water conditions within EPA guidelines. Replace filters sooner if you notice a pressure drop of 10-12 psi from the original pressure (e.g., if the incoming pressure was 40 psi, but now it's below 30 psi). Sediment-Heavy Water: In areas with heavy sediment, the Sediment Filter may need replacement more frequently, even before the other filters. Best, Express Water
Will this remove both fluoride and chlorine at the same time? Or are there other set ups for fluoride
Dear Valued Customer, Thank you for taking the time to contact Express Water. For a whole house system unfortunately unable to remove Fluoride, reverse osmosis (RO) is the most effective method for removing fluoride from the water. Additionally, activated carbon filters can assist with removing chlorine. Combining these approaches can provide comprehensive filtration for both fluoride and chlorine. Please do not hesitate to contact our office directly at (800)992-8876, Monday-Friday, 8am-5pm (PST) should you have any further questions or concerns. We are here to help!

Does your filter increase the acidity of the water, which can cause corrosion in copper pipes?
Dear Valued Customer, Thank you for taking the time to contact Express Water. No, the 3 Stage Deluxe Whole House Water Filter System - Ultimate Protection (SKU: WH300SCKP) does not increase the acidity of the water. The system is designed to remove contaminants without altering the pH balance significantly. However, if you have concerns about corrosion in copper pipes, it's always good to monitor the pH of your water and ensure it's within a neutral range. Please do not hesitate to contact our office directly at (800)992-8876, Monday-Friday, 8am-5pm (PST) should you have any further questions or concerns. We are here to help! Best Regards, Express Water Team
I have purchased 3 Stage Deluxe Whole House Water Filter System - Ultimate Protection - WH300SCKP. Do I also need to also purchase and install a Sediment filter WH100SS before the WH300SCKP filtration system?
Dear Valued Customer, Thank you for taking the time to contact Express Water. Instead of a Sediment filter as the first stage, there is a Phosphate filter, which can also reduce sediment If you have issues with larger pieces of sediment in your water, we recommend looking into installing our Spin Down Sediment Filter The Spin Down Sediment Water Filter 50-Micron is a pre-treatment and will help reduce the rust, sand, dirt, silt, scale, and other sediments in your water. It is low maintenance and comes with a reusable water filter cartridge. It is high-efficiency which can filter up to 0.25 gallons per second. Please do not hesitate to contact our office directly at (800)992-8876, Monday-Friday, 8am-5pm (PST) should you have any further questions or concerns. We are here to help! Best Regards, Express Water Team
Do you install your product at Residential?
Dear Carol, Thank you for reaching out to us. Unfortunately, Express Water does not offer in-person installation services at this time, and we currently do not have a list of verified licensed installers available per region. Our best recommendation is to find a local licensed plumber either on Yelp or Google, and please make sure that the installer is experienced with under sink RO Filtration Systems or Whole House Systems prior to the installation. Please note that installation costs will vary depending on the install location, amount of labor and extra parts required, service area, etc. Thank you for your understanding and consideration.
