Product Description

This Pentek 150233 20-BB 1” #20 Big Blue filter housing with pressure relief is suitable for high-flow and heavy sediment applications. The opaque blue sump is made of reinforced polypropylene for strength and resistance to chemicals, and the black cap is made of high-flow polypropylene (HFPP) for stiffness. The black cap has 1” female National Pipe Thread Taper (NPT) threaded input and output connections and a nitrile butadiene rubber (Buna-N) O-ring to ensure a watertight seal. A pressure relief button on the inlet side of the cap releases pressure in the housing for changing filter cartridges. The housing can be used with a 20” x 4-1/2” filter cartridge (sold separately). It has an initial pressure drop of 1 pound per square inch (psi) at a flow rate of 15 gallons per minute (gpm), a maximum operating pressure of 90 psi, and a maximum operating temperature of 100 degrees F (37.8 degrees C). This filter housing meets National Sanitation Foundation/American National Standards Institute (NSF/ANSI) standard 42 for quality assurance, and is for use in various high-flow applications, including residential drinking water filtration, food service, and irrigation, among others.

Water filters remove undesirable particles, chemicals, and microorganisms from water by means of a semipermeable barrier, adsorption, or biological processes. They are made of densely packed synthetic or natural fibers that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralization. For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings. Filtration systems typically consist of a series of two or more types of filters, each designed to remove different contaminants. The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum flow rate, and the amount of water that can be filtered before the filter must be replaced. Water filters are used in a wide range of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.

Pentair manufactures industrial, commercial, and residential water filtration components and systems. The company, founded in 1966 and headquartered in Minneapolis, MN, meets International Organization for Standardization (ISO) standards 9001 and 14001 for quality assurance.

I just finished installing a complete whole house water filtration system using these Pentek Big Blue Filter housings. I'm very happy with the performance of my system and how well it all went together. Here's a breakdown of the all the components I used in my system. The goal was to reduce some sediment, iron deposits from old iron pipes and remove any chemical taste. The water tastes great now and is crystal clear.


-Pentek Big Blue 20" Filter Housings
-Housing Bracket for Big blue 10" and 20" filter

Filters IN ORDER:
1-Pentek DGD-2501-20 Spun Polypropylene Filter 20 micron dual stage to 1 micron.
2-Pentek 155263, RFFE20-BB Radial Flow Iron Removing Filter
3-Pentek RFCC-BB Carbon Filter

you can add another Filter after the Carbon for media if you want. Not necessary but is an option or run 2 sediment filters in beginning of the system.

-Various copper pipes and PVC pipes to build the system. I highly recommend a bypass valve and a way to shut off the water to your filters if you need to change them without losing water pressure to the house.

-I experienced nearly 0 PSI drop thru the 3 filters and no noticeable change in flow rate.

I know the dimensions are given, but the size of this thing is surprising when seen in person. I had a water softener and charcoal filter installed but felt I needed a prefilter to prevent premature failure of the media in those two filters. I wanted something that would take a large filter so that I wouldn't have to change it as often and also maximize flow and this thing fits the bill. The life expectancy of the sump is 10 years so I should get plenty of life out of it.

My only complaint is that while directions aren't necessary, the product doesn't come with screw to mount it to a bracket, nor does it indicate the proper size. I had to do some research to find the right sizes needed. Those turned out to be 5/16" x 1 1/4" lag bolts for anyone looking at one of these.

These are the standard by which all others are measured. I live on a small farm with 3 low flow wells and they all have their problems. Currently I'm doing a 2 step process bringing water into a cistern and then into the house from there. I've had a big blue before the cistern and then one between there and the house for several years now. Good flow, great pressure, never a problem, never a leak. I couldn't ask for more. I'm now setting up a second cistern for irrigation water and just ordered two more and noticed these are hardly reviewed. It's a shame as these are a great product.

I bought this as a pre-filter to my Aquasana EQ-1000 whole house filter. I also bought the Pentek 150237 10" Big Blue Filter Housing as a post filter to the entire system (I am using the same review for both since I had the same experience with both). I also bought the brackets for the Big Blue filters found here on Amazon. I live in an area that on a good day might get 50 psi of water pressure so I wanted to keep as much of the pressure as possible. Seeing as I was lucky enough to have a 1" service line on my house, I kept the plumbing 1" up until I got to my utility room. So the filter system would have to be before the utility room on the one inch line.

Installation: to connect the housings to the supply lines, I used brass compression fittings. This would allow me to completely remove the individual housings should I even need to perform maintenance. These fittings were tricky to find as I had to go to a plumbing supply store to find them. So they thread into the housing and then compress onto the 1" supply lines. Whatever you use, make sure and use plumbing tape on the threads but not pipe dope. For some reason I was told not to use that. As for the brackets, if you do not get the screws needed to attach the housings to the brackets (and you do need the brackets), they are 5/16 1¼" long lag screws. The housings are not threaded to accept screws which is why you use lag screws. Once the bracket was in place, I set a 5/16" washer on the lag bolt and then used a socket wrench to slowly start tightening the bolt in place. Just be careful and go slow and it will go in straight. Repeat for the other three. To attach the bracket to the wall, you can 3/8" bolts whatever kind suits your method of attaching it to the wall.

Like the 20" big blue filter housings, but purchased two and one of them leaks at the pressure release button.
Called Pentek and they sent a replacement button with spring, but it still leaks unless you press it in manually from the filter side of the cap. Seems a defect in the housing cap...but not worth the hassle to cut the plumbing to replace it as it works fine providing you dont push the button until you are ready to change the filter (which is the intent anyway). Still only 3 stars due to the quality problem out of the box!

My big gripe about this product is about the little things and maybe most of those are related to the vendor. First, the unit shipped to me had a broken tab on the inside. There are a half dozen tabs in the lid to hold the filter centered. One of those was broken off. Then, the lid itself leaked, kind of oozed water out of the fittings. I'm wondering if I was sent a used unit. Perhaps the previous owner over tightened the fittings and caused some sort of invisible micro fractures that let the water ooze out?

OK, so that is one issue that could be solved by not sending out a used item. The second issue is that the mounting bracket doesn't come with it, so be prepared to spend another $16 just for the bracket. Oh, and then the bracket doesn't come with the screws to attach it to the filter. It really seems like they're just trying to nickle and dime you. The worst part is you don't know this until you receive the filter, so it is back to ordering and waiting again and again. Overall, a pretty lousy experience.

How does the filter work? OK. It is just a big cylinder that you put a cartridge into. One thing to note. There is no down tube in this thing. It just relies on the filter head pressing into the filter cartridge to seal off the flow of water and force it through the media. The little tabs on the underside of the head are supposed to keep it in alignment. Not sure how great a design that is, but I guess it works OK. The quality of the output is going to depend more on the cartridge than on this housing.

Would I buy another? Good question. I am setting up another piece of equipment and have a need, but I'm going to browse around some more before I accept that this is the best option.
