## Overview

The Pentair Pentek 150233 Big Blue Filter Housing is a heavy-duty, 20-inch water filter housing designed for whole-house filtration systems. Featuring a high-flow polypropylene cap with 1" NPT inlet/outlet ports and compatibility with all 20" Big Blue cartridges, it offers superior capacity and durability. Its extra-large size reduces the need for multiple vessels, making it ideal for high flow-rate and heavy sediment applications. Certified by NSF and ANSI, this housing combines trusted Pentair quality with easy maintenance via a pressure relief button.

## Description

Pentair Pentek Big Blue Heavy Duty Filter Housings offer the versatility to meet all of your large-capacity filtration needs, including highflow and heavy-sediment applications. The extra large housing allows for greater cartridge capacity, reducing the number of vessels required for high flow-rate applications. Sumps are available in both 10" and 20" lengths. The High-Flow Polypropylene (HFPP) cap is available with 3/4", 1" or 1-1/2" NPT inlet and outlet ports. The 1-1/2" internal port allows a greater volume of liquid to pass through the HFPP cap more rapidly. Big Blue Housings are compatible with a broad range of chemicals and are available with or without a pressure relief button. They accept a wide variety of 4-1/2" diameter cartridges.

Review: Works Great! Bigger is Better! - Have been using this filter housing for over 5 years and am glad I bought this model. The filters are large and therefore do not get clogged very fast. I clean them once every 18 to 24 months and they are still far from being clogged and have no pressure drop. The first filter is 30 micron, second is 10 micron. I will change the second filter to 5 micron. This is on a well and apparently the well water is very good so ymmv. The only negative are the brackets. I reinforced them with another bracket and strongly recommend doing that. When filled with water these housings weigh a lot more than you would think and move too easily, possibly loosening the pipe connection when servicing the filter or bumping into the housing. Their is enough room to attach the bottom bracket hole to the filter bracket with a nut and bolt without screwing into the actual filter housing. Wood lag screws are good for attaching bracket to the wood wall plate. Brackets: Everbilt 4 in. Zinc-Plated Heavy Duty Corner Brace
Review: Solid brand, solid construction, o-ring included - What can I say, it’s the name brand Pentair, solid feeling, everything looks like proper sizing and fitment. Overall good quality.

### ⭐⭐⭐⭐⭐ Good Replacement for METEK HD-20-10HFPP "Big Blue" Cartridge Filter Housing
*by G***) on February 12, 2026*

Perfect replacement for my broken METEK HD-20-10HFPP "Big Blue" House Cartridge Filter Housing which had cracked at the bottom and was leaking. The METEK brand no longer seems to be made. The Pentair screws perfectly into the old METEK Cap, so no need to call a plumber to re-attach the water pipes into the new Pentair cap if you don't need it. This Pentair Housing Set did not come with a new Housing Wrench, but I had my old one. So order a new Pentair Wrench if needed as well, or you could use a universal rubber strap cinch wrench.
