## Overview

The Pentair Pentek 166219 Big Clear Filter Housing is a heavy-duty, 10-inch whole house water filter housing featuring 1" NPT ports and a clear Lexan sump for easy visual monitoring. Constructed with reinforced polypropylene and equipped with a pressure relief button, it supports high flow rates and is compatible with standard 10" x 4.5" Big Blue filter cartridges, making it ideal for demanding residential or commercial filtration needs.

## Description

Pentair Pentek Big Clear Filter Housings offer the versatility to meet all of your large-capacity filtration needs, including high-flow 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 cap is available with 1" NPT inlet and outlet ports. The 1-1/2" internal port allows a greater volume of liquid to pass through the cap more rapidly. Big Clear Filter Housings offer on-site examination of flow, performance, and cartridge life and are ideal for a variety of applications. The 1" polypropylene caps are available with a pressure-relief button on the inlet side to relieve pressure inside the housing . Caps are constructed of reinforced polypropylene. The 10" sumps are made of Lexan and the 20" sumps are SAN (Styrene acrylonitrile).

Review: Five Stars - OK +
Review: So much potential but ... - LOVE the clear body of this filter to see if the filter is loaded up or not. However, wish they could have included the mounting bracket and minimally the 1" - 5/16" lag bolts to mount this to a bracket since most hardware stores start carrying the 5/16" lag bolts starting at 1.5" long and not 1" long that is needed here. Also make sure you get an extra gasket (or 2), since the square gasket does NOT like staying in the groove and can be easily damaged needing replacing.

### ⭐⭐⭐⭐⭐ premium clear housing with pressure release valve. 1" in/out ports
*by F***L on 14 September 2024*

I use this for a pre-filter and for recharging the water softener on my RV. Need the clear one to see when the salt is done for recharges. Very sturdy. Has plastic threads for in/out, but with them being 1", you just screw in a brass fitting and they are very secure. Really love the build quality of Pentair housings. Had normal big blues before and they were extremely durable. I do use a pressure regulator keeping the pressure at 50 psi or below, so I can't speak to whether the clear housing will take higher pressures...but these are pretty hefty and well built. Just don't leave the clear housing out in the sun...they are not UV resistant (per Pentair).
