Quality filter!
This is a quality product and I suspected it was a soon as I picked up the box. I guess I’m kind of old-school when it comes to plumbing products, if it feels heavy enough to be exhibit A in a murder trial, it’s probably OK. The primary housing is a quality piece of cast brass expertly machined to appropriate standards. It comes with fittings, allowing you to convert it from 1 inch to three-quarter inch and as an extra bonus it comes with two shark bite, three-quarter inch adapters. These easy to use push connectors cost $10 apiece if you go to buy them separately. The ball cock on the bottom serves as an easy clean function, and also will release the pressure on the system in case you want to take it apart to give the filter a more detailed cleaning. The filter is a permanent one made of stainless steel or some closely related alloy. Things you should know; first it’s a clear housing in a high impact quality plastic. This allows you to visually inspect the filter to see if it needs a flushing. However, if it’s in direct sunlight, it can turn into kind of a terrarium, and you’ll get algae growth. You can solve that by draping an old towel over it. The other thing you should know is it’s not really a filter it’s a pre-filter. It is a 50 µm built-in system. It will handle dirt, fine sediment, bits of sand even rust, but it’s not going to take out absolutely everything. Depending on your situation and the quality of water, it might be fine by itself or you might want to follow it with a different system down stream with a 1 or 5 µm filter to really do the job. This prefilter will greatly extend the life of your filtration system. Make those expensive replacement filters last longer.

Works good but needs a longer drain hose.
The small hose to let the filter water come out was small and very short. We had to buy a longer hose so we could drain the water to the outside. Other than that, the system is fine.

Easy installation
I had a previous lower quality unit that blew out the seals and I could not repair it. This unit is so much better quality. Took me no time to install with the included shark bite connectors. No leaks and didn’t have to redo any of my work. I did swap the filter screen to the included 500 micron filter. I have well water and use this filter for my outside faucets and sprinkler system only.

Bought two with different screen size. Believe it or not helps with Ref water makers as it filters out those fine sand materials. Also east to back flush

Great filter, perfect for our application.
This was easy to install and works great. I have a water treatment that uses activated charcoal. Over time the charcoal granules break down and clog the aerators in the sinks. This required me to clean and or replace the aerators every week or so. This filter was installed after the treatment system, with the larger size screen. Since I installed it a month ago we have not noticed any reduction in water pressure or had to clean the aerators. I like the clear filter canister; I can look in and see the status of the mesh (and do see some particles captured there). The cleaning cycle works well to flush them out, so it won't be necessary to keep buying filter cartridges. I don't know why I waited so long to do this!

Plugs up quickly
Filter Screen is very fine a is easily plugged. The pipe adapter were sent with thread tape but I could not get it to not leak. Using flush valve doesn’t clear the screen much.

I installed this on my water line after my pressure tank from my surface well to catch sediments. After a year of use, It still in good quality and work's well. You can see if sand is trap's in the bottom so you just open the drain valve and the spring push the separator down and clear the deposit. I fitted a hose in the bottom so the water flow directly to my drain. My plumber who worked on my house said it was well made and good quality

Purchased product as a support to finer filter system. It catches larger contaminates before the reach the finer filter, however after a short time the o'ring became worn and united started to leak, upon contacting the supplier about a new o'ring their representative, Carina sent me a whole new unit!! The gesture was very much appreciated and will allow me to fix the leaking issue. Definitely a well supported product that I would recommend to anyone needing such a system
