Pentair Pentek BBFS-22 Big Blue Two-Housing Filtration System, 1" NPT #20 High Capacity Water Filter Housing, Holds 20" x 4.5" Filter Cartridges

Easy to install. Feels very solid. Water quality greatly improved.

After about 3 years fighting with my iSpring filter, I have now replaced it with the Pentair Pentek BBFS-222, and I am much happier. There were no huge issues with this iSpring, but there are a lot of little things that the Pentek does better.1. The inlet and outlet threads on the iSpring are oversized, and they leaked until I put about 20 wraps of teflon tape on the fittings. The threads on the Pentek are slightly oversized, but not as bad. My fittings bottomed out instead of sealing at the threads, but there has been no leaking with only 4-5 wraps of teflon tape.2. The iSpring housings leak unless they are tightened down with a wrench, but then they are almost impossible to remove again. This is actually what prompted me to replace it; I broke my filter wrench trying to change filters. The o-ring setup is completely different, and the Pentek housings only need to be hand tight with no leaking.3. There is nothing in the iSpring housings to keep the filter cartridges centered when installing. The Pentek housings have little fingers that keep the cartridges centered.4. The mounting bracket on the iSpring puts the housings too close to the wall, which makes it difficult to use a filter wrench without pulling the housing away from the wall. The mounting bracket on the Pentek holds the housing far enough from the wall that using a filter wrench is no problem. It required a little re-work of the existing plumbing to make the change, but totally worth it.

This is a great choice for a whole house water filtration system at an affordable price. The three filters address my problems with sediment, chlorine and scale.Pros:Reasonable priceWell established companyInterchangeable filtersCons:Needs spaceVery heavy, especially when filled with water.Changing filters can be difficultNo wrench included.Filters can be expensiveIncluded bracket mounts to wall with only two bolts. It’s not strong enough.

had a softener and bleaching system to remove close to 3ppm iron and sulfur(egg smell). I now have no iron showing up on the test and no smell is present. I have a I wish I had installed this system years ago, it is easier to maintain, smaller, works better then my old system and the best of all it is initially MUCH MUCH cheaper and is similar in yearly cost.filters used in orderHome Master CFDGD2501-20BB Multi Gradient 25/10/5/1Home Master CFRFFE-20BB Radial Flow Iron ReducingHome Master Radial Flow GAC 20 Micron Replacement Water Filter

Used these on a few different clients house as a pre-filter before their water softener system. Works really well to filter sediment from well water. Quality’s really good.

I considered using the 10" filters because they would be lighter when changing. These 20" beasts are HEAVY when full of water. But, these 20 inchers flow well and don't require changing as often. Just be ready to put some muscle in to it when you unscrew that final thread! I installed my system 9 months ago in a two person home and just changed the filters out of curiosity. My gauge showed there still wasn't any significant pressure drop... And, the filters looked like they could go longer, corroborating the gauge findings. This is Trinity aquifer well water in Kerrville, Texas. I used a 200u spin down, a 50u pleated, and a 5u wound string filter. Works fabulous ahead of the water softener. And I use the rust remover softener salt along with. The spin down was nearly pristine so I'm changing it out for a 100u screen, see what happens.UPDATE 12-28-22: At 20 months post install no problems. No failures, leaks etc. 11 months since the last filter change and no pressure drop yet, I changed the filters anyway… This time I’m cleaning the pleated filter rather than trashing it. And I have two so I can just swap out. I have a video showing the system install on my yt channel, mguerramd.

Absolute waste of time and money… Housing leaks straight out of the box, plumber couldn’t fix it during install, I then bought new o-rings (properly lubricated) and that didn’t fix it. Guess I’ll have to pay the plumber to come out again and remove it so I can return. Also must add that the 20” housing fitted with a filter and full of water is crazy heavy. I’m a 6’2” strong guy and feel like this is an ergonomic design issue… lastly the pressure release valve is dumb, just squirts water everywhere. Very disappointed!6/26/23 update - Ordered a replacement and I kid you not, it was missing orings!!! Thankfully I had two new orings left over from troubleshooting the first leaky filter housing so I was able to use those, but it only gets worse from here… I inspected the sealing surface in the upper housing and found a small knit line on the same location of the same upper housing (the one with the pressure release valve). And guess what the new one leaks too! Bad quality control on Pentair’s part. Amazon needs to stop shipping these and get Pentair to fix the injection molding parameters to get rid of the knit line. I also think the oring is not getting enough compression otherwise the compliance of large cross section oring should compensate for such a small surface defect, bad QC and bad design!
