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: So far so good - This filter system works well. Was a bit of job to do it myself but I got it done no leaks. We definitely can tell the difference on our well water. We had a smell issue and for the most part it's gone. With interchangeable filters you can try the different filters and see if they can help with whatever issue you may have. We are satisfied with it's performance. Water pressure is same as it was before the filter was installed. For the price it a good deal, it seems depending on what filters you ger the prices do change but the housing is the same on the different units. Water is clear and cool. We have a RO unit so we don't drink the tap as it's well water. ## Features - [Lowers Water Hardness] With a dual-stage filter combination, this Waterdrop whole house water filter effectively reduces iron and manganese ions in water, while also reducing other heavy metals such as mercury, lead, cadmium, chromium, and copper, helping to lower water hardness. - [Effective Filtration] This 10"×4.5" 2-stage water filter combines an iron & manganese reduction filter with natural coconut shell GAC carbon.

I followed the directions and the process went great. I made a stand to hang the filter housing . I did the recommended 10 wraps with Teflon tape. I used a 1" NPT to a 3/4 GHT fitting as I was connecting to water hoses. With that much tape used I had a slight issue with the fittings trying to cross thread but with a little patience they finally started correctly Our seasonal site has alot of iron with a yellowish color. I flushed the filters according to the directions then hooked up to the RV. Fantastic water Great tasting absolutely clear water. Very pleased. No leaks!!!! I purchased 3/4 wide Teflon tape . Lots easier. ## Frequently Bought Together - Waterdrop Whole House Water Filter System, Reduce Iron & Manganese, with Carbon and Sediment Filters, 5-Stage Filtration, Reduce Iron, Lead, Chlorine, Odor, 2-Stage WD-WHF21-FG, 1" Inlet/Outlet - Waterdrop Spin Down Sediment Filter, Backwash Whole House Water Filter System for Well Water, 40-50 Micron, 1" MNPT + 3/4" FNPT + 3/4" MNPT, Traps Sand, BPA Free, WD-RPFK - Waterdrop FXHTC AP810 10" x 4.5" Whole House Water Filter, Replacement for GE® FXHTC, 3M® Aqua-Pure AP810, Culligan® RFC-BBSA, W50PEHD, GXWH40L, GXWH35F, DuPont WFHD13001, Pentek® R50-BB --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.om/products/447115446-waterdrop-whole-house-water-filter](https://www.desertcart.com.om/products/447115446-waterdrop-whole-house-water-filter) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-07-22*
