Pentair Pentek 150237 Big Blue Filter Housing, 1" NPT #10 Whole House Heavy Duty Water Filter Housing with High-Flow Polypropylene (HFPP) Cap and Pressure Relief Button, 10-Inch, Black/Blue

It's been a while, but I needed a Big Blue housing for a project. I didn't even know if they were still available, but a quick scan and up pops this Pentek - It's gotta be Pen Pure - right? Wow they're still selling them! Price is right, ordered one right up, couple days later, another Amazon box....When I saw "Pentair" on the label, I took a deep breath. Not made any better by the "Made in China" that followed. Oh-oh - this could be bad! Hmm.. looks pretty decent, No!, it's good!(Pentair is a huge industrial corporation, highly respected)I was in the commercial water treatment/RO business back in years ago, and the Pen Pure brand was well respected, as was their version of the standard Big Blue 4.5" (in 10 or 20") housing, often used as a prefilter for smaller commercial RO systems with a depth filter and a CBC to prep for a TFC membrane. That's what this is being used for, and I'm very happy to say, the quality is as good as they were back 20+ yrs ago. You can't say that about too many things that have aged that long and had their manufacture moved to China. I wish it was made in the US, but if it had, I doubt it would be sold at this price point. (We used to get a case of 4 for $99, and once in a while the wholesaler would throw in elements if you bought a few boxes) Small things tell you about quality, and how much a manufacturer cares about it. As always, I grabbed my silicone grease to lube the o-ring, and I also grease the threads lightly too to ease removal and prevent "plastic stick" which can be annoying on this size housing. Anyway, I opened it up and there was the o-ring (not in the groove, in the bowl - a good thing, so it doesn't take a set) and it was already lightly lubed up. A manufacturer that cares enough to do that cares about their product. Always, and still a Penn-Pure/Pentek/Pentair Big Blue customer. 5 stars across the board! Even "Flavor" - I assume they mean the water? That would depend more on the element than the housing, and raw water.One negative - No L bracket and screws with the housing. They used to come gratis, heck I had dozens of them floating around I didn't need, now think I can find one? Still giving five stars on "Ease of install" even though I should take one back, I figure these are available in 1" and 3/4" which saved me some grief. If you're listening, Amazon and Pentair, at least mark "bracket not included" and link one. They're not the same as a standard 10" x 2.5 one. The bolt pattern on a Big Blue is 3" x 3" with 4" to center to the bend - hope that helps someone out. (love that they kept the Imperial pattern) You can drill and tap 1/4npt for a gauge, and the original brackets are notched both sides to clear the bleeder and gauge (and allow 'flipping' if necessary)Bottom Line:These are a high quality housing at a fair price, and I highly recommend them.

fits fine and does the job. Threads are poly-propylene so do not mis thread. Then again there is no problem finding the gaskets for the pentail name. That is the reason why.

I've had two of these installed in series as a whole-house water filtering system for just over a decade. One day I was reading that the manufacturer recommends replacing the housing every 10 years, and knowing mine were at least that old I thought I'd see if they're still available. They are, I purchased two new ones, and they appear to be exactly the same quality... pretty rare for so many products now-a-days that get worse yet more expensive with time. These things are really cost-effective, even if you toss them every 10 years or so. And it's easy to swap out filter elements if you use a little food grade silicon on the o-ring and threads and don't tighten them too much. I suspect my originals would have lasted forever as they are made really well... and I did put the old ones in a box to save them for an unlikely emergency. But with new ones I should be good to go for a long time. Highly recommended!

The previous canister broke so Amazon had it and it arrived just in time to replace.

I have a BIG BLUE filter that was installed in my house in 1992. The O-Rings that one gets in a Big Box store ...or even a local Ace Hardware store, are just slightly too large for the original blue housing.I suspected that the design of the housing had been modified since 1992 and purchased this item so I could get O-Rings that fit. I was also hoping that I could just screw the new housing onto the old "black" part of this filter assembly.That's exactly what I was able to do. The new O-Ring did fit into the new blue housing and the new blue housing screwed onto the old "black" part of the assembly.Problem solved without having to hire a plumber to install the new filter assembly
