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

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 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

We live in northern Wisconsin and there is a lot of iron in our well water. We had an odor in our water that was mostly noticeable in the shower. I added a second big blue filter for a carbon filter. The odor is completely gone now and the water tastes great.

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

One more update: I previously posted "27 micro mesh filter", which was a mental math error. The filter is supposed to be good to 5 Micron particles, which is about the size of fine dust. Sand, by comparison, is about 75 microns (which could be filtered out by a 200 mesh screen). With a 5 micron filter, NOTHING (sediment/sand/etc.) should be getting by this filter, but apparently, everything is. I've tried two different 5 micron filters. I've tried sealing the top and bottom (where the filter mates with the canister housing) with vegetable jelly/grease. I don't know what else to do but to chuck the whole Pentek housing and buy another product. This problem is ruining my tankless hot water heater, and every faucet is becoming clogged. It's a real disappointment.*********************************************** *******************************************************Update: With two different cartridges, this filter DOES NOT do the job. I have a 27 micro mesh filter on my water heater filling with grit that a 5 micron filter in this casing is not capturing. Also, my faucets and shower heads are plugging up. Whatever this filter casing is designed to do, it's not sealing sufficiently with the filter to keep unfiltered water from passing through. I used " Icepure ICP-PPL10BB 10” x4.5” Universal Whole house big blue sediment pleated water filter compatible for Pentek S1 series" filters.Waste of money. Worse, it's a waste of time and doesn't do the job.*********************************************** *******************************************************I'll give this a strong 4-star. It's a quality, well made product.However, there are a couple of things you need to know, that the advertising doesn't make clear. The ad talks about a predicted 0.5 psi drop, but that's likely measured WITHOUT a filter. I installed a pleated sediment filter, which research told me was likely the least restrictive filter. My city-provided water provides 53 PSI, which is just above the minimum for my Rinnaii tankless water requirement (minimum 50 PSI). Adding a pleated filter in this housing resulted in a 6-9 PSI drop to about 46-49 PSI. The water heater hasn't complained, but it was an unwelcome surprise (however, one which I probably should have expected).Second, and another review has mentioned this, the brass fittings installed with Teflon tape leaked, and leaked badly. I've R&R'd both intake and outtake fittings, using a plumber's trick of applying both pipe dope to the threads, coated with Teflon tape. I've had these kind of molded receivers leak before, and this has solved the problem, and so far, it looks like it's working here as well. There doesn't seem to be a crack in the tough plastic top at the intake/outtake, but it won't seal easily on it's own with just tape. Be forewarned.Other than that, it looks like very solid construction, which is what you must have if you're going to make this a part of your pressurized water system. If it "breaks", it could cause many $1000's in flooding. I'll follow up if anything changes, but I think we're "good" with this installation.

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.
