Great filter system
I installed this filter system back in summer of 2019. Took a buddy and I a bit to do because how my basement is setup and what the previous owner did with it. Once I mounted the chassis to the wall, it was relatively straight forward to plumb the water into the filter system with shutoff valves before and after the unit, and a drain valve after. After a year and change of use, this system is still performing amazingly! With the initial set of filters, the middle (charcoal) filter completely blocked the flow and would not allow any flow through. I ran with it removed for a bit, and that was an automatic improvement in my water quality! Chlorine was mostly gone! While this was going on, I contacted Express Water, and they sent me a replacement set immediately. Great company to work with. When I went to install, this new filter worked perfectly. Even more improvement in the water quality! I frankly find it disgusting the amount of sediment that has been trapped. That filter turned DARK BROWN! I can't imagine going without this whole house filter! It says it works up to 80 psi, and I am close to that at 76 psi. No leaks, weeps, or anything. The system is great! One note: If I have one con, it's that the filter housings do not have drain valves on them.

Great filter system
What a difference this made for my whole house. The water filter makes the shower water softer. I feel cleaner when I get out to dry. Clothes are so soft and it removed the well water smell. Great product

This is a great whole house water filter solution!
I installed this as a DIY project using PEX tubing and SharkBites connectors and valves. While this was probably a more expensive option it was something I wanted to try. I did have difficulty connecting into the unit with a 1" metal threaded connectors. I believe this may have caused some damage to the threads on the input side. However, the company worked with me and provided me a replacement for the first stage head at no cost so I was able to repair and install the full unit. Their customer support was incredible to work with. They want the product to be successfully installed and will work with you to make sure you are happy. The one suggestion I would make is if you have to adapt the one inch connector to a three-quarter inch connector, use a PVC 1" to 3/4" threaded connector and install it into both ends first. This way if you have any problems you just replace the pvc connector, not the full first stage head. While this was it doable installation, it required some thought and a little bit of plumbing experience to put it together. Even hiring a plumber to install this would be worth doing if you are not comfortable with this kind of work. In the end, I am extremely happy with this product. It works well, doesn't impact the flow rate of my well water, and my water tastes great. I no longer have to worry about putting filters on every sink in my house. They have a great product here for a reasonable price. Other contractors wanted to come in and install similar systems four four times as much. If you are a little handy or can have someone install this, it is well worth the purchase price.

installed since a May
I had the choice of having a system installed by a company for $6000 (I am in CA...land of rip off) and after researching online I decided to go for a system that I will assemble myself with the help of a plumber. It cost me around $1000 adding all bits and pieces. I also added an additional filter in front from 3M. It has been installed since April, it is great, no leaks and nothing complex in the installation (three valves and all gages work properly..a lot of examples online for this system). However, I made one mistake in the choice of the setup. I installed it outside as I didn't have space inside. Even though, I choose an area which is partially in the shade so it wouldn't be exposed too much to the sun light. I have transparent containers on two of the filters. There will be green Algae growing in the filters if you dont clean them regularly or protect them from the sun totally. I thought it was cool to see what the filters look like from outside but choosing the transparent option was a mistake. I should also have built a small box (or put a sleeve around the transparent containers) as fast as I could to protect the filters from the algae growth. Not a huge deal and not coming from the system...just environment and my choice. lesson learned and will adjust the system. Overall, when it was clean it was working great and made some water analysis at that time which confirms the quality of the system. Hope this helps.

Good Quality user friendly filter
Good filter unit, brought my radon levels down from 4000 pCi/L to 750 pCi/L after one month of use. I have installed two of these units. One had some defective pressure gauges, the other was fine. It is good quality but not the most robust. Easy to install and maintain. I would recommend the unit. It is not recommended to use with radon levels above 6,000 as it accumulates radiation will give off radioactive material.

Cet équipement de Express water a été très facile à installer. Il est certain qu'une plomberie en PEX est un jeu d'enfant. Ce système me coûte beaucoup moins cher que ce que voulait me vendre le commerce de pompes local. Mon problème d'odeur de souffre et de goût de sel en raison de mon autre équipement ont été complètement réglé. Je suis donc pleinement satisfait et après neuf mois d'utilisation, je n'ai pas encore changé les filtres. Je pense le faire dans trois ou quatre mois.

Excellent system!!! Our municipal water is almost undrinkable due to the chlorine levels, after installing this our water tastes amazing!! We also paired this system with a 100 and a 50 micron sediment spin down filter and UV Sterilizer.

Easy to put together and to change the direction of flow. Seems well built and sturdy. The manual is fine for what it is. The only problem with it is that the in/outlets are 1"NPT. Basically impossible where I am to find anything 1" that isn't black iron as the housing is plastic. Getting from 1" down to 3/4" PEX without 10 different fittings or spending another 150$ to do it in all copper was a bit of a challenge. If only they included a couple for bushings to bring it to 3/4" which is a bit more standard for a home plumbing system.
