Waterdrop WHF21-PG 2段階 家全体浄水器システム NSF/ANSI 372

Delivers clear and silt free water from my well every time.. easy to install and use

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.

Great Quality improved my health

I have want a filter on the in coming water supply to my house for some time. With some recent repairs getting done it was the perfect time. I checked with Lowe's and Home Depot and while Lowe's had what I wanted, Home Depot did not. So I checked Amazon and found this one. It was what I wanted and at a lower price. With costs every where going up stupid fast saving every dime has become important. Pros: 1. Large capacity. It filters our entire daily water usage with no issues. 2. Standard size filter elements, makes replacement inexpensive. 3. Easy install. Take the bracket off the housing (8 screws make it easy) when drilling the holes to mount it. Then re-attach the bracket to the housing and hang it. Super easy. 4. All materials needed to install the filter, except plumbing fittings are included. 5. Easy to understand instructions. There isn't much to installing one of these, yet a lot of Chinese made products have crappy instructions. Cons: 1. Opaque housing means you can visually assess the state of the filters without opening the housing. 2. Filters need to be replaced regularly. This is the down side of all filters. Mine has been in for less than 30 days so no idea of the actual service life. Word of caution. Some articles say you should replace the filter every 3 months. You will need to determine this on your own. A family of 5 uses more water than a family of 1 or 2. So you need to monitor your water quality and determine your own replacement interval. After installation, mine had a leak. Turns out, one of the inlet fittings was cracked. A replacement came from Amazon with their usual mediocre delivery schedule. The replacement works perfect, no leaks. Overall I am pleased with this filter.

Decent product other than the plastic 1 inch female inlet and outlet threads. The threads are not made correctly, they are oversized so the fittings leak. In the instructions is says to wrap 10 turn of the provided t-tape around the fitting. This is not correct plumbing procedure for a reason. You can’t fill a poor thread with tape! I had no choice so I followed the instructions. One side leaked and the other didn’t. Recommend staying away from this one and buying filter housings with brass inserts. I’m experienced with all pipe fittings because this is part of my trade.
