PUREPLUS 2-Stage Whole House Water Filtration System, 10"x4.5" Universal Home Filtration, with Sediment, Carbon Block Filter, Reduce Chlorine, Taste, Odor, Includes Pressure Gauges, 1" Inlet/Outlet

Had a Friend who is licensed Plumber assist with the installation, and we have no leaks so far (this review is 4 months after install).... Seems that the Inlet and Outlet seals/adapters are the most challenging part of install.... I am VERY satisfied with the result, and functionality of this housing.... Plain string-wound filters work for approx 3 months before needing a change (2 person household, slightly higher than average water usage) .... Filter change-out is simple and takes maybe 10 minutes.... I use Food-grade Silicon spray on the O-rings at installation AND filter change.... You really do not need to monster-grip tighten the housing.... just snug-it and your good. (60 PSI).

This is a quality system with brass fittings and excellent filters. I highly recommend this filter system especially after returning a poor quality system from another company that had plastic threads and SEVERE leaks.

My first attempt installing this was a nightmare, it leaked no matter what I did. Finally got it sealed then when it came time to change the filter it leaked again. The filter housing is well made, it is heavy duty, has dual O rings on the blue housing at the top above the threads. SOOOO>>>>>>> Here's what I did that solved my problems, FIRST the threads in this filter are NOT true NPT so when you buy a bushing to reduce 1 inch down to 3/4 inch it is very sloppy. MFG says 10 wraps of Teflon tape.... I had more than that with pipe dope, still dripped. The threads are brass, so my first install I used a brass bushing's (1 inch reducing to 3/4 inch)The main problem is...the depth of the female threads (of the filter) is too deep for the length of the brass bushing, so the bushing can't bottom out before hitting the filter housing on the outside. Which means the sloppy threads with the American NPT bushing is difficult to seal.So, I went to the local hardware and got new bushings made of Galvanized pipe again 1 inch down to 3/4 inch. The galv. bushing has about two or three threads more in length. BUT.... because the bottom of the female threads is flat, and so is the bottom of the male bushing threads. I got an O ring and made sure it had to be pushed in to set flat inside the female ports, which takes 90% of the stress of the water pressure. See the picture...Now the bushing does not bottom out...but does squash the O ring to help with the seal.Think of it like putting a nozzle on the end of your garden hose. (It will leak without a washer) I still used Teflon tape on all threads but did not need more than 4-5 wraps. NO LEAKS YAHOO!!BE SURE TO...Use food grade grease on the rubber O rings and threads of the blue housing when installing filter, and when changing filters.DO NOT...sweat copper near the Teflon tape...sweat the pipe fittings first then wrap the tape and install the pipe, making the last connection (sweat) AWAY from the Teflon tape. (Even then I used a wet rag wrapped around the Tape to absorb heat)Hold the RED button down while SLOWLEY filling the filter with water, let go when water comes out vent.HIGHLY RECCOMEND........Installing bypass for service...so that you don't have to shut down the whole house and drain the pipes. See 1st Picture.Also be sure to release the pressure (RED BUTTON) when changing the filter, helps un-screwing the housing.One last thing.... the filter that comes with this when new only measures 9 &3/4 inches tall. I have tried 10-inch-tall filters that are supposed to fit but seem to be too tall for the housing to screw in far enough for the two O rings to seal. (again see #1 pic-very little gap when screwed in all the way) Only 1/4 turn past snug.It can work :)

I bought this 2-stage filter to place between my water well head and pressure tank. It is well made and you can reverse the inlet/outlet (which I did) depending on your equipment placement. There are pressure meters at both filter cartridge housings that will make it easier to detect when the cartridges need replaced.

A few weeks after I had this on my home the inlet side of the filter started pouring water out around the thread. After getting it off and inspecting . There is a brass 1 inch sleeve that is letting water come out behind it. Faulty product. I'm am not happy after spending this much for a good filter and have it not be anybody. DONT BUY!

Easy install ,water quality is excellent. Absolutely satisfied !!

Arrived well packaged and fast. The filter unit works well with minimum pressure drop.

Bought to add a 'pre filter' to my whole-house water softener.Quality of materials seemed adequate, but lackadaisical quality assurance ("QA") caused me much extra work and expense: The 1" inlet on the Right side of the unit was adequate, but on the Left side of the unit was entirely inadequate/bad. Why? In the USA, NPT (National Pipe Thread) is 'tapered'. The threads are a bit larger at the opening, slowly getting narrower the deeper you screw in the fitting. The Left hand inlet was, indeed, standard 1" x 11-1/2 tpi - but it was NOT tapered. I could not screw in the male 1" fitting more than a quarter turn (1/4 turn). No good, would pop out if slightly disturbed.By the time I discovered this, and since everything else was acceptable, I decided to purchase a cheap NPT Tap, which I had to modify so as not to cut into the unit's plastic body, and futz around for an hour until I got a satisfactory 'taper' to accept my fitting. (BTW I tried 3 different 1" male fittings in this bad inlet, including a PVC fitting - None would fit. It was this filter unit's problem until I re-tapped the inlet).So at least it works now. No leaks. Just a bad day at the factory final quality check- or worn-out tap tool at the factory is my guess.It happens. I'm not returning it, but If I wasn't a strong DIY sort of person, I would have sent it back.
