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: 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: Can this unit be used in a condo?**
A: Hi,
Thanks for your interest in our whole house filter product.

Since this filter uses 1" fitting, if it can be connected to your current water line, it should be able to use in a condo.

**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:

I hope this information may help you.
Please feel free to let us know if you have any other questions. Thank you.

### ⭐⭐⭐⭐ 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.
