Review: NO LEAKS!! If using polypropylene fitting adapters, combining plumbers putty and tape - We DIY’d the replacement install of this upgraded whole house water filtration system. No fitting/adapters are included, normal practice, as everyone’s situation is unique. The instructions did not specify a preferential material type of fitting adapter/s. Just that the system was a 1” female and in our case we needed to adapt to 3/4” home pex plumbing. The first 2 times attempting install, we used metal adapter/fittings, both times the system leaked. The metal also caused the female threaded area in the unit, to shed a small amount of plastic with each install. First install attempt we used plumber’s tape wrapped around male threads 10 times, as the instructions recommended. For the second install attempt, we used plumber’s putty, it still leaked. Determined to stop the leaking, I searched on you tube for install video’s. One video showed this exact system and they used polypropylene adapter fitting. So here on desertcart, I found a heavy duty polypropylene hose fitting that adapted from the 1” to 3/4” (Banjo HB100-075 Polypropylene adapter). They worked great with both the system and our Pex plumbing. Used a heat gun to soften the Pex, then pushed the Pex into the barbed 3/4” end. Allowed it to cool down. On the adapter’s male threaded end, we applied plumber’s putty to the threads, added 4-5 turns of plumber’s tape and ended with a thin layer of more plumber’s putty, (over top of the tape). The putty helped the plumber’s tape to adhere much better than usual. We then ended with a small amount of plumber’s putty over top of the tape. In the system housing on the 1” female thread area, we applied a small amount of plumber’s putty. After hand installing the fitting adapter into the unit, we used a metal adjustable wrench to tighten it down. It took “3rd times a charm” but we are now very happy with this system. We have a high iron content (16ppm) and so far, the system seems to be working out great!! It is much better than the single unit we replaced. If I can figure it out, I will update this review on how long these filters last. If they don’t last long enough, I will upgrade to the better filters available. This will help extend time between filter replacements. Just a side note: I also learned from the YouTube video, to use a “food grade” lubricant/grease on the large O-rings. It will allow less friction on the ring, therefore allowing the ring to last longer. There are two O-rings on each filter casing. The top one comes off easy, so the whole ring could be coated. The bottom ring is tight, so I did not remove it. I applied the lubricant just on the exposed part of this O-ring. Hope this information makes everyone’s install experience so much easier. Use polypropylene fittings/adapters ONLY, NOT METAL!! Also use both the combination of plumber’s putty and tape!!
Review: Great product and excellent customer service - Unit is great - installed easily and works perfectly. On initial installation, there was a very small leak (1 drop per hour) coming from one of the red pressure relief buttons. I contacted customer service and they gave some tips and immediately offered to replace it if needed. I excercised the button a few times and rotated it and he leaking completely stopped. It is working great and dry for a couple weeks now. Customer service was great!

**Q: Is the filter delivered alongside the machine, or do I need to buy the filter separately?**
A: Dear Sandra,
Thank you for your inquiry. The system comes with two filters – a PP cotton filter and an activated carbon filter. The PP filter requires replacement every 3-6 months. The GAC filter requires replacement every six months. We recommend buying extra filters for an emergency and here is the link for your reference:

### ⭐⭐⭐⭐ Excellent job removing iron
*by M***L on March 7, 2026*

The filter does an excellent job removing iron and sediment from our well water. The water now runs clear without staining. The only issue is the pipe threads are oversized and wouldn't seal with pipe tape even using lots of it. I did get it to seal using a pipe thread paste.
