Review on ISpring F4WGB21B Replacement Filters 2 Stage by Crystal Smith

I live in a city with bad water (old pipes, mud, frequent bursts) and we often get recommendations to boil water. After 3 in a 2 month period I finally went to the filter shop and bought the WGB21B whole house filter set and the WSP-50 coarse sludge pre-filter. Installation was easy; Inlet Water Pressure Control Valve Kit WSP-50 and WGB21B, all connected with just threaded fittings and teflon tape. Whatever plumbing you use to supply or drain water to the rest of the house, whether copper or PVC, does not affect the connections between the devices in the regulator filter kit; threaded connections only. Having just replaced my first set of cartridges, I realize I should have done so a long time ago. The amount of black, viscous dirt caught in the filters was incredible. Much more than you might expect. He even loaded a coarse filter (a stainless steel cartridge that can be washed and cleaned with a small brush). The carbon cartridge also seems to remove chlorine well. My drinking glasses usually had a faint white coating because our local water supplier had filtered and chlorinated the aquarium water. Now it's gone. I am very happy with the filtering system and the iSpring client is exceptional. When I originally bought the filters, I called iSpring with a few questions about the filter, filter element types, and a bunch of other questions. The customer service reps, especially Don, were very knowledgeable and extremely patient with my beginner questions. there was a lot of garbage in our water) water in their house or city.
