Pentair Pentek 166142 Big White 20-Inch Whole House Water Filter Housing with 1" NPT #20 Port & Pressure Relief Button - Heavy Duty White Water Filtration System for Clean Drinking Water, Well Water Treatment, and Home Plumbing Protection

I purchased a home with an undersized (2 7/8) whole home water filter. My well water is pretty good, but it has sediment, iron flakes, and has a slight sulfur dioxide smell. I was using 2um carbon filter from WM or HD for about $5 each, but they would clog up in ~2.5 - 4 weeks. I decided to upgrade and install a Dual BB system with a sediment pre-filter and a carbon block main with pressure gauges in between to judge filter life. Based on the smaller filter's performance I think sediment is my larger problem, because it tended to clog prior to the carbon's ability to remove the SO2.I went with a the Pentek R30-20BB Pleated Polyester Filter, because it is supposed to be reusable with a quick rinse. I haven't had to rinse it yet so I can't say how well it works after rinsing. There were many complaints that the Pentek EP-20BB Carbon Block Filter reduced system pressure by ~5 PSI. My pressure tank runs between 50 psi to 32 psi and to be honest I don't notice the pressure drop at all. My well pump is rather quick and only takes ~30s to raise the pressure back to 50psi. I suspect that's masking the filter concerns others had.The installation was pretty straight forward. I'd recommend MAP over propane for soldering as I could finish a joint with ~15s of heat. I would also highly recommend a good heat shield. I had to solder some joints next to drywall and my heat shield was able to withstand all that heat without transferring any of it to the drywall. It wasn't even warm.My only complaint is that the filter housing doesn't include a wrench. I was able to hand tighten them, but I'm sure I'll need a wrench to unscrew them. I also had to order a third filter housing as one of the original ones had broken tabs which hold the filter. The return and refund process was easy and quick. No complaints there.Hardware List from Amazon:(2) Pentek 150467 20-BB 3/4" Big Blue Filter Housing with Pressure Relief(2) Watts Housing Bracket for Big blue 10" and 20" filter housings(1) Pentek R30-20BB Pleated Polyester Filter Cartridge, 20" x 4-1/2", 30...(1) Pentek EP-20BB Carbon Block Filter Cartridge, 20" x 4-5/8", 5 Microns(3) Simmons 100PSI PRESSURE GAUGE(2) Homewerks 119-4-34-34 No-Lead Full Port Ball Valve with Drain with 1/4-Turn...Hardware List from Local:3/4 pipe, flux, solder, heat shield, MAP torch, fittings, 5/16" x 1 1/2" lag bolts, washers, etc..3 month update:Everything is still working great. At 3 months I haven't noticed any pressure drops due to filter clog, but we've started to notice some SO2 smell in the water. I pulled the pre-filter and washed it off. The tank had sediment in it and it was clear the filter was doing it's job. I pulled the carbon filter and I was surprised by how clean the tank and filter are. I couldn't see any sediment in the tank or on the filter. I decided to rinse it just because it was out.My plan is to keep using the carbon block until the SO2 becomes too bad to bear. I think the pre-filter still has another 6 months in it before I have to rinse it again.
