(Original 4 star review before the plastic wore out)
Installed as a whole house filter on the incoming city water. Used the 5 micron filter it came with and now changed it after the recommended 2 months. Having this clear housing is so much better than any of the ones you can't see through. You can change your filter earlier or later depending how dirty it gets. I'll probably change it more frequently (see picture). Very happy that none of that dirt/silt/rust/etc isn't going through my washer, water heater, and shower. I installed a 2nd unit under my kitchen sink and put in .5 micron filter for the cold water so the water we drink or cook with is filtered 2 times. Definitely better taste. Switching the filter was easy and only took 5 minutes or so which included rinsing out the clear part with hydrogen peroxide. Very very convenient to have the ability to turn the water off in the unit so the filter can be changed without having to install extra shut-off valves like other filter housings.
(B) After that low quality experience, I looked at other brands. They are a similar price, identical size filters, and include the filter spanner.
(C) pressure locks on the filter housing. Once you've closed the valves, you must relieve pressure before it will open.
First off, I discovered that the big o-ring had been installed incorrectly by the assemblers and it was pinched, rendering it useless. Secondly, three layers of teflon tape on the pipe fittings was not enough to prevent them from dripping. So, after working the o-ring with a heat gun to remove the kinks, and using pipe dope over teflon tape over pipe dope on the pvc pipe-thread fittings, I finally got it to stop leaking. Or at least it appears to not leak at the moment. I’ve been fooled before by this poorly constructed head. And I’m only running a 30-50psi system!
Like another reviewer mentioned, it appears that the female NPT fittings of the head are too deep and thus the shouldered pvc fittings can’t go deep enough to match the taper, and thus they don’t close and seal properly - an obvious design flaw. So, one has to fill the thread gaps with teflon and goop and then tighten down very hard - almost to the point of cracking the plastic fittings.
Lessons learned: check that the o-ring has been pinched during assembly and use lots of pipe dope and teflon tape on the pipe threads. If I have to rebuild the fittings again, I will use a 3” brass nipple sunk deep into the head (coated with copious amounts of dope), and then attach my pvc fittings from there.
So, four stars for the concept and price; minus 2 stars for assembly, design, and construction.
