Review on Cleanse Your Home'S Water With ISpring 3-Stage Whole House Water Filter System - WCB32O by Rob Marsh

Update 2.7.22. These filter housings are the worst I have ever installed. It took 3 attempts to stop the leakage from the female threaded housing. I used triple-thick Teflon tape and T2 Dope reinforced with fibers. I wrapped the triple thick tape 7 times and then applied a thick layer of pipe dope (the best they make of both). Let it sit for a few hours (though not required) and installed the 3 filter housings. Turned on the water and dang two of them leaked (though slightly). I tightened them a quarter turn and it appeared to stop the leak. An hour later a droplet appeared on both, I turned it a 1/8th of a turn tighter., so far so good, no leaking. If it leaks again, I will take apart the two fittings, put 8-10 wraps of the TRIPLE thick Teflon, and apply the pipe dope. Take my advice and follow my instructions or buy a different filter system. (my buddy a machinist said "the manufacturer made a defective threaded housing unit"). Besides that, I have plumbed dozens of homes and commercial projects, and never have I experienced such a poor-quality product. Needs to be recalled as defective.Update 2.5.22 7.36 pm. Took apart 6 threaded connections, used plumbers dope sealant and reconnected fittings, allowed dope sealant to set up for 1.5 hours, though the sealant does not require any drying time. Dang, It LEAKED again! I am again taking it apart and am going to use both Teflon tape and the dope sealant. ISpring unit is really poorly designed at the female thread connection.The first review today was @ 5.30 pm. I read the warnings from others installing this unit and the seller's recommendations. I wrapped the threaded connections 10 times with Teflon tape (the good Teflon stuff) I Turned on the water and dang all 6 threaded connections at the ISpring filter housings leaked.
