## 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 a pressure relief button, it supports all standard 20" x 4.5" filter cartridges. Its extra-large capacity reduces maintenance frequency while ensuring high flow rates, making it a top choice for professionals seeking reliable, durable filtration solutions.

## 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.

### ⭐⭐⭐⭐⭐ Works Great! Bigger is Better!
*by N***L on October 16, 2022*

What can I say, it’s the name brand Pentair, solid feeling, everything looks like proper sizing and fitment. Overall good quality.

### ⭐⭐⭐⭐⭐ A Very Sturdy, Good Quality Canister
*by T***F on April 14, 2017*

This is a very sturdy, very large 20" sump for a household water filtering system. It arrived on time and in excellent condition. I got exactly what I ordered (some folks had issues with receiving a 3/4" in/out when ordering this 1" version). It took me a couple of assembly attempts getting a good seal on each of the two canisters I ordered since the large o-ring slipped out of the groove, but a 2nd attempt got everything sealed good and tight. Be sure to use the silicon lubricant that's provided. Not only does it provide a better seal and easier removal later, it's also fairly gooey thus helping to hold the o-ring in place while screwing the canister to the cap. These things seem to be heavy duty and I expect them to last for years. Be sure to order the optional metal mounting brackets since these guys are fairly heavy, especially after filling with water. I would not be comfortable letting my piping support the weight as some have mentioned. I configured a two stage filtering system--the first filtering out 5 micron particles and the second taking it down to 1 micron. I don't need carbon or iron filters since I have good quality well water other than the sediment particles. I recommend this item and would buy it again.
