Review: Excellent Customer Service and Leak Issue Resolved - After reaching out to Waterdrop Filter customer service, I am pleased to update my review to a 5-star rating. After explaining the steps I had taken using a SharkBite 1" MNPT fitting, the after-sales team quickly understood the issue and agreed to send me a new filter. This allowed me to use a 3" brass nipple to extend the fitting away from the filter housing. I installed the new unit using the extension and am happy to report that it worked perfectly — no leaks at all. I want to express my sincere thanks to all the customer service representatives at WaterdropFilter.com for their professionalism, responsiveness, and support in resolving the problem. It’s great to see a company that truly stands behind its product and values its customers. I purchased the Waterdrop Whole House Water Filter System mainly for its advertised DIY installation ease. Unfortunately, I’ve experienced multiple leaks during setup. I used standard 1" MNPT push-to-connect fittings, but the problem is that the fittings bottom out at the outer flange of the filter housing instead of within the threaded inlet/outlet. From my professional experience, you should still see some of the white tape exposed when a fitting seats properly — this isn’t the case here. Because of that, achieving a reliable seal has been very difficult, even after trying multiple sealing methods. My water pressure is steady at 60–65 PSI, which is ideal. The filter’s design is appealing, but if the internal depth of the female threads were just a bit shorter, this would easily be a 5-star product. I’ve reached out to the seller for advice and hope Waterdrop will replace my unit so I can retry installation using a workaround I believe will help. If not, I’ll unfortunately need to return it and look for a different system.
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!!

## Features

- 【Efficient filtration】The impressive 10” x 4.5” PP filter and GAC filter combination achieves a 5-stage filtration, effectively reducing large particles and sediments larger than 5 microns. The whole house water filter also reduces chlorine, lead, benzene, mercury, peculiar smell, sand, rust, and more. GAC filter adopts natural coconut shell, which reduces funny taste and odor, while improving the water taste for you. With this filter, you get constant pure water with a better taste.
- 【Longer lifespan】The GAC filter is expected to be changed every six months, while the PP filter is due for a change every 3-6 months. Waterdrop’s house water filtration system features longer lifespan, therefore saving your potential replacement cost. The durable housing is made from food-grade materials only. It has passed tests to confirm work under the pressure of 25-90psi without external damage and crack. The pressure is daily water pressure in USA. To extend the service life, it is best to use it with municipal water.
- 【Stable water flow】The whole house water filter system has passed 100,000+ water hammer tests to ensure the stable and safe water supply. The large water capacity is enough to provide the whole household pure water with a smooth and stable flow rate.
- 【DIY installation】The installation is so simple that you can do it on your own following the instructions in the manual. The included wrench facilitates the replacement, installation, and related processes. Please wrap the telfon tape appropriatly, wrap too many turns or too thick will shorten the life of the copper.
- 【Protects water appliances】This 10"x4.5" whole house water filtration system protects your water pipes from rust and extends the lifespan of your water-related appliances by delivering clean water source without clogging.Waterdrop is an independent brand.

**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:

### ⭐⭐⭐⭐ Does the Job
*by K***N on January 1, 2026*

I live in Wilmington NC, and the water is toxic. This does a great job! Removed ammonia, and Chlorine and lots I did not test for. That being said. The threads leak. Lots of ways to fix it but I should not have too.
