The water filter is great. Definitely noticed a difference in my water quality. Unfortunately the bass fitting cracked on the inside after 2 weeks of operation. Just passed my 30 day return. So i called the company and we exchanged emails and they are sending me a replacement part. I am so pleased because it really is a good system and the customer service was outstanding. I will always promote this company. Irene was very professional and had a lot of hospitality, hence why i will continue to buy their products. You wont be disappointed. Try them out if you’re looking for a whole house system.***I will post pictures….As for the copper or brass fittings you need to use a lot of Teflon tape so the connections don’t leak or over tighten. In my opinion it works best this way. I have been playing around with it leaking for about 2 days now and that what I think is best. As for PEX I’m not sure if this would be an issue I just like copper/brass just me. Anyways the pictures are attached on how I twisted the teflon tape and then wrapped it to close the gaps. Orientation is important for the tape!!! Look it up on YouTube if unsure. I posted an example but make sure you use a lot so it can seal properly since the gaps are to lose. Hope this helps.

I've tried several different whole house water filter systems and this is by far my favorite. To keep this short I'll give you a quick overview. A lot of these systems leak it's one of the most common problems. The weak point is the connection ports. To fix that problem on this system they use brass threads which is strong and prevents cracks and leaks. The second common problem is reduced flow rates over time. This system can flow up to 15 GPM which is higher than most. This allows for the system over time to keep filtering and not have a noticeable reduction in pressure or flow. That also saves money in filter changes.My water quality with this system and paired with the HQUA UV filter is incredible! No smells, bad tastes or anything floating in the water. After having a water test I've removed all the problems and now my water is in spec with state guidelines. The best part is it tastes great and I know my family is safe drinking it.Features:High Flow Quality Filters: The most important thing is obviously the filters. This system uses a Sediment Filter which strips solids before they get to the second filter. The second filter GAC + KDF removes heavy metals which are common in well water and city water. The third filter will clean up odor's, color and the big one chlorine found in almost all city water sources.Oil Filled Pressure Gauges for each filter: These are industrial quality gauges that allow you to monitor the pressures coming out of each filter. This will tell you if you have a loss in pressure and which filter needs replacing. They thought about everything and even prewrapped the threads with Teflon tape.Filter Drains: Each filter housing has a drain at the bottom that allows you to drain sediment that can prematurely clog your filters up. You can also purge the filters under pressure to clean them off which gets you a longer filter life.Red Purge Buttons: Each filter has a red air purge button at the top to blead off air in the system.Reversable In/out flow: This system allows you to change the in/out location to make installation easier depending on your current plumbing.Extra Gaskets: The system comes with extra gaskets and even includes the silicone lubricant to save you money.Fittings: They include 3/4" and 1" fittings for installation so you save money again on the parts.Cleaning Brush and Wrench: This is the only kit I've seen that includes a cleaning brush for the filter housings. You also get the wrench to remove the heavy duty filter housings.Instruction Manual: Large Print, Easy to Follow, Pictures, Trouble Shooting. It's all included in the instructions I was impressed with the attention they put into this to make it easy to understand and install this system.Customer Service: Here is one thing you may not know you need until you need it. I've reached out to customer service and had an answer in less than 24 hours. HQUA stands behind their products and wants you to be happy. This is my second filter from them.

The HQUA WF3-01 3-Stage Whole House Water Filtration System has exceeded my expectations! It effectively removes heavy metals like lead and mercury, along with sediment, chloramine, and odors, leaving the water crystal clear and great-tasting. This is definitely a heavy-duty system built to last, and the build quality feels top-notch. Installation was straightforward, and I’ve noticed a significant improvement in water quality throughout my home. It’s also reassuring to know it reduces VOCs. Highly recommend this system for anyone looking for cleaner, healthier water!

I’m very happy with this filter. Installation wasn’t too hard with the fittings they included. The filters are large and can filter a lot of water without loss of GPM or pressure. I was very happy to see no leaks at all when I pressurized the system. The purge valves on the bottom of the filter housings are really nice because you can drain them before you change the filter which takes a lot of the weight out of the housing. Last but not least the water is very clear, no smell and tastes great.
