Spin down sediment filter
So I have not installed this yet, but I must say the quality of build was definitely well thought out. However, someone did mention the mount that is supplied really isn’t a mount, but something it rests on. So that would be the only thing that is a dislike about this product. A lot larger than I pictured. The brass head is heavy duty and the screens seem to be well made as well. The ball valve on top moves smooth so easy to use and straight forward. All good materials. Look forward to getting this installed, it will save the life of my filters.

Product support doesn't listen, they suggested I call a plumber-- RESOLVED
Filter is solid and appears to be built well. Installation was straight-forward. Like other reviews have mentioned, the wall mounting bracket will support the filter, but not hold it in place. I went to change the filter cartridge for the first time (after about 6 weeks), but when I moved the top control to "Off", I still had flow from the filter bowl. I tried several times, but couldn't get the flow stopped. The valve handle moved smoothly and gave no indication of problems. I contacted Waterdrop support and they told me to service the valve or call a plumber. They also sent a nice video of how to open the filter housing to change the cartridge, but not how to address the "Off" setting not functioning properly. I tried again after my conversations with support, and was able to get the "Off" setting to work and change the filter. No idea why it took several tries to seal. I will likely add isolation valves to help with this. UPDATE: After leaving a negative review, Waterdrop contacted me about replacing the filter. Turns out the "Off" postion does not isolate the filter from backflow from the output side of the filter. Once I added a valve to the output side, I was able to prevent gravity backflow (filter in basement). At this point, the only negative remaining is how fast the filter gets clogged by the silt from the well-- certainly not the filter's fault. I'll have to see how well the backwash performs, now that I have a downstream valve.

Nice idea with double mesh filtering
Nice idea having 2 cartridges in one like 100 and 50 mesh in a big container. Giving 4 star due to provided tricky “union” connectors to reduce main thread on the unit 1-1/4 MNPT to “1 MNPT and 3/4 FNPT“. It is hard to install it with leak proof and also it’s hard to find on the market some solid reducer 1-1/4 female to smaller size, to avoid using this “union” adapter.

Great Spin-Down Filter With Minimal Pressure Drop
I installed the Waterdrop Mega Spin Down Sediment Filter on my whole-house system, and so far it has been working perfectly. The build quality feels solid, installation was straightforward, and the dual 50-micron + 100-micron filtration is a nice upgrade from my old setup. What impressed me most is that there’s almost no noticeable pressure drop — the water pressure before and after the filter is essentially the same, which isn’t always the case with sediment filters. The reusable design and easy backwashing are added bonuses that should make long-term maintenance simple. Overall, I have no complaints. This filter performs well, keeps sediment out of the system, and maintains strong water flow. Highly recommended.

Great solution for removing sediment in water
Was easy to install and set up. Much less residue in our water. Did exactly what I wanted it for.

Good quality. Poor mount design and poor wrench to change filter.
Build quality is very good. Kit includes fittings to adapt it to both 1" and 3/4" Pex adapters. Only complaint is the mounting bracket is not very well designed and it makes it very difficult to use the included wrench to unscrew the filter mounting ring. I am a fairly skilled mechanic and I can't do it without removing the filter from the wall mount and putting it on a work bench. That means I will have to use push fittings for the PEX input and output so I can change filters. I wonder if they included the wrong wrench. It rally sucks. Everything else is very good.

You need to use enough Teflon tape to prevent leaks, but works amazingly
Excellent
