Constructed from reinforced polypropylene with a high-flow polypropylene cap, it features a pressure relief button for easy cartridge replacement and supports standard 10" x 4.5" filter cartridges. Rated for up to 100 PSI and 100Β°F, it ensures reliable, long-lasting performance for residential and commercial water filtration needs. ## Description This Pentek 150469 3/4 #10 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 3/4 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 10 x 4-1/2 filter cartridge (sold separately). It has an initial pressure drop of 2 pounds per square inch (psi) at a flow rate of 15 gallons per minute (gpm), a maximum operating pressure of 100 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.SpecificationsFilter cartridge size (H x W) (sold separately)10 x 4-1/2 inches (254 x 114 mm)Initial pressure drop at 15 gpm2 psiMaximum temperature100 degrees F (37.8 degrees C)Maximum pressure100 psiMaximum dimensions (H x W)13-1/8 x 7-1/4 inches (333 x 184 mm)Materials and structural integrity certificationNSF/ANSI standard 42H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.Water filters remove undesirable particles, chemicals, and microorganisms from water by means of a semipermeable barrier, adsorption, or biological processes Review: Pentair makes good quality products and this filter is no exception. Since its a standard size 10β€œ water filter there are a lot of filter cartridges that will fit this model. While it didn't come with a mounting bracket, i found the Rainfresh BH010-6 bracket was a perfect match. Additionally, the Rainfresh CK2 adapter kit allowed for a quick & simple connection to the copper piping i cut in. Review: 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. ## Features - Large filter housing for high-flow and heavy sediment applications - Reinforced polypropylene sump for strength and chemical resistance - Use with a 10" x 4-1/2" filter cartridge (sold separately) - Pressure relief button for easier cartridge replacement - Initial pressure drop of 2 psi at a flow rate of 15 gpm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0045LQSG0 | | Best Sellers Rank | #72,675 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #242 in Replacement Water Filters | | Brand Name | Pentek | | Capacity | 15 Gallons | | Container Type | Cartridge | | Customer Reviews | 4.1 4.1 out of 5 stars (195) | | Global Trade Identification Number | 00051678504697 | | Installation Type | Under Sink | | Item Dimensions L x W x H | 33.3L x 18.4W x 33.3H centimeters | | Item Weight | 4.49 Pounds | | Material Type | Polypropylene, nitrile butadiene rubber | | Maximum Flow Rate | 15 Gallons Per Minute | | Model Name | Pentek 150469 3/4” #10 Big Blue Filter Housing | | Model Number | 3/4” #10 BB Black/Blue HFPP w/PR | | Other Special Features of the Product | High-Flow Cap, Pressure Relief Button | | Purification Method | Sedimentation | | Supported Water TDS Level Maximum (PPM) | 1500 | | UPC | 051678504697 | | Unit Count | 1.0 Count | | Upper Temperature Rating | 100 Degrees Fahrenheit | ## Product Details - **Brand:** Pentek - **Capacity:** 15 Gallons - **Material:** Polypropylene, nitrile butadiene rubber - **Product dimensions:** 33.3L x 18.4W x 33.3H centimeters - **Special features:** High-Flow Cap, Pressure Relief Button ## Images ![150469 3/4" #10 Big Blue Filter Housing - Image 1](https://m.media-amazon.com/images/I/41szemFkCYL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***T on 28 January 2023* Pentair makes good quality products and this filter is no exception.

Did a bunch of research and this seemed to be the #1 GoTo. Installed fairly easily in a couple of hour,s putting it after the pressured tank. Inserted filter and the sediment is gone and the water is running clear. ## Frequently Bought Together - Pentair Pentek 150469 Big Blue Filter Housing, 3/4" NPT #10 Whole House Heavy Duty Water Filter Housing with High-Flow Polypropylene (HFPP) Cap and Pressure Relief Button, 10-Inch, Black/Blue - Pentair Pentek DGD-5005 Big Blue Water Filter, 10-Inch Whole House Sediment Filter Cartridge Replacement, Dual-Gradient Density Spun Polypropylene, 10" x 4.5", 5 Micron, Pack of 1 - Pentair Pentek SW-3 Spanner Wrench for 10" Big Blue Housings --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/400926751-150469-3-4-10-big-blue-filter-housing](https://www.desertcart.co.uk/products/400926751-150469-3-4-10-big-blue-filter-housing) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-30*
