Review on ISpring WGB21BM 2-Stage Whole House Water Filtration System, 10” X 4.5” Carbon Block And Iron & Manganese Reducing Filters, 1" Ports by Marc Burke

Would like to have had the 3 filter unit but due to very limited space in my small main floor utility room I chose this one. My crawlspace is unheated in my small ranch therefore the only place for the well pressure tank, washing machine and filters was the utility room. I replaced my pressure tank and manifold at the same time. I had no problem installing. Used 2 pieces of 1/2" x 3-1/4" solid wood trim I had extra and mounted between studs one on top of the other and two lag screws through the mounting bracket. This held the heavy filter unit very solid. Then 1" to 3/4" pvc adapter and brass 3/4" to pex inlet and outlet lines wrapped both with tape and thread sealant and no leaks like some others have experienced. Also have a ispring spin down filter as prefilter. Gave orings and threads in filter housings and spin down filter a coating of silicon lube. I did have to remove the 8 screws holding the mounting bracket to filter housings and turn it around so the arrows for inlet and outlet were in correct direction. I had waited 3 weeks for my amazon order and could not really get started on replacing my pressure tank and manifold until I got filter unit for proper spacing so I called and ispring sent me a head unit which I received before my order so I could get a start on my install which is fantastic customer service and I now can use as a spare. Seems like only a little loss of pressure after install.Using teflon tape and thread sealant on all joints as well as pex crimp clamps on 3/4" line resulted in absolutely no leaks the first time system was turned on. Water at times still came out a little muddy due to years of junk in lines but that is clearing up fast. Toilets are much clearer now. Only time will tell on how long before filter changes but for now very satisfied with this unit.
