## 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: Quality of the original PenPure Big 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 desertcart 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, desertcart 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.
Review: Good option for RV multi stage filter system - Great quality. Solid build and worked well with the components I used to build my filtration system.
