Pentair Pentek 150671 Big Black Filter Housing, 1" NPT #10 Whole House Heavy Duty Water Filter Housing with High-Flow Polypropylene (HFPP) Cap, 10 Inch, Black/Black

Just keep in mind 1" Adapters Cost 11+ Each and the Depot doesn't sell them usually. Used Post Water Softener + Post 15 Micron mesh filter. This setup does reduce water pressure somewhat; if you have a setup where you can increase the water pressure a little that will help re-normalize the pressure. If you don't have a 3/4" hot water feed, your water pressure will take a significant hit especially as the filter gets clogged over time. I use a 1 - 25 micron gradient water filter in this unit. If you have a 1/2" hot water feed, I would probably go with just one 10 micron filter to minimize water pressure drop; unfortunately most of the crap falls between 0.5 microns to 10 microns so....

Update: oct 30/25. Just hooked up second housing i bought last year wen i did the review. Thinking or hoping that it was just the one bad housing..NOPE!!!. SECOND ONE leaks as well..these are garbage!!.. Just took for granted, sell as a package..nope..no bracket..😵‍💫👎 Damn thing leaks..no matter how tight i get it..still dripping. O ring is in good condition but damn thing still leaks!!!

Nice filter housing

Tried everything to prevent this from leaking. It has a slow leak with the gasket. Replaced that gasket and it still leaked.

No matter how tight you fit the filter housing, it leaks. Poorly designed. I don't understand how you can go through all the effort of making something like this just to make it so poorly. Also, does not come with a mounting bracket or a body wrench.
