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

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 Amazon, 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!!

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!

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.

Check to be sure you get the one with the filters you ordered. The one I received had the 2 filters installed. they are white, one with a grey top, one with a white top, no label showing what they are supposed to remove. My primary reason for ordering this one was to remove/reduce the taste and odor of chlorine and remove sediment. I do not know what the preinstalled filters are supposed to remove or limit. Should have checked before installing the filter. I only removed the filter holders to see if there were filters installed, I trusted Amazon.😫 I would have returned it but it too long to install it, I/we had to reroute the plumbing. I will use it a while to see what the water taste and smells like, if not satisfied I will purchase new replacement filters. Then I will update my review. Update 2 March: Note: Waterdrop did not ask me to change my rating, After using the filters for over a week the system is doing what I hoped it would do. Also, I agree with others that said Waterdrop Customer Service is the best. They contacted me and offered a total refund, even after Amazon's 30 days return had expired, Since I am satisfied I did not return it, then they offered to send me new filters since the ones installed were not labeled. Since the filters seem to be doing what I needed done I will keep using them.

It’s true it will leak that’s why they say use lots of Teflon tape. Just wrap the 1” fittings with a few wraps of tape and also use a pipe dope safe for drinking water. Now let’s see how well it works on iron from our well water.

Had iron in my well water. Turned my water a yellowish color. This system was affordable and easy to install. Water is clear as it should be now!

This filter claimed to remove rust. It does no such thing kind of hard to return something after you even installed it waste of money.

We live the iron range in Minnesota and our well water reflects that. We had iron staining in sinks, toilets and bath tubs and our tapwater was pretty much undrinkable used bottled water for drinking. We installed this filter a little over a week ago and the change was miraculous, no trace of an iron taste straight from the tap, no discoloration in anything since. Now the bad. I’d read the reviews about people having trouble with leaks but thought since I’d been a pipefitter that wouldn’t be a problem. It was. I tried Teflon tape, pipe joint dope, combination pipe dope and tape, 30 wraps of Teflon, all leaked both sides. The filter housing has loose running threads and not tapered pipe threads. The only way I could get the leaks to stop was to use two part epoxy and epoxy bushings into the inlet and outlet, after that no problem.

Heavy duty product..

Good quality and seems be working as advertised. I used pipe thread tape and compound as well the first time plumbing in the fittings. So far no issues with leakage. Haven’t had my water tested since being installed but has noticed our hard water/iron smell has gotten better since instalment. Only has been a few days but hoping it’ll only improve with time. Happy with the purchase thus far.

Make sure to wrap at least 15 wraps of tape....there is a defect in the bronze connector on the inlet and outlet that won't seal unless you use lots of teflon tape. Other than that, they are a great cheaper filter option

Nice product easy to install

Works awesome. Thank you
