Pentair Pentek 150233 Big Blue Filter Housing, 1" NPT #20 Whole House Heavy Duty Water Filter Housing with High-Flow Polypropylene (HFPP) Cap and Pressure Relief Button, 20-Inch, Black/Blue

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. These have to be attached to the wall with preferably something sturdy either to the studs or a board attached across the studs.Use: once everything was connected, I washed my hands thoroughly and took the O-ring and silicone lubricant that came with the housing. I spread a thin layer of the silicone lubricant in the channel using about half of what came with it. I then seated the O-ring in the channel and pressed down all around. Then I used the rest of the lube on the top of the O-ring. In the future when changing the filters, I plan on reapplying the lubricant. You can find it in your local hardware store for under a buck. I dropped in my filter and screwed in the blue bottom of the housing to the top. Once it was hand tight, I used the filter wrench to give it a little tighten. It didn't turn very much with the wrench but it seated it firmly. Open any shutoff valves to the housing and check for leaks. If there are any, immediately shut off water to the housing and tighten up areas with leaks. Once you are leak-free, be careful with the red pressure relief button on the top! It doesn't take much relieve the pressure and water will start shooting out.With my entire system in place, I did not notice any loss in pressure so this worked exactly as expected!

When our house water filter had a slow leak, I called our plumber. He said this suppliers were charging at least $180 for the wholesale price! He sent me the link on Amazon to this Pentair Pentek housing, which was only the third of the wholesaler's price! Since the plumber installed this new filter housing, everything is working well. No leaks!

I put a 100 micron spin down and two of these in line ahead of my softener. A pleated 50 micron followed by a wound string 5 micron. They clean a huge amount of sediment and iron out of my well water. As well, I put a few ounces of resin cleaner in the softener brine for every regeneration. The resulting water is soft, crystal clear and tastes great! You can drill and tap the bottom of these for a ball valve. Then, you can drain the sump before changing the filter. These 20” sumps are HEAVY when full of water. Another trick is to bolt a shelf to the wall just below these, (leave enough clearance to unscrew!) so when you unscrew it, and can’t control the weight, it will only fall a few inches instead of to the floor. Which will break it. Go to my yt channel, mguerramd, to see a video of how to clean and back flush a pleated filter, and save a ton of money on filters.

The media could not be loaded. Purchased this 20” Big blue Pentair filter as we live in an area that constantly has issues with dirty or brown/yellowing water. The filter is missing the media or filter cartridge. Also it’s missing the mounting kit and screws. I don’t know which screws I used but length were 1 inch and were flat tip. I wished they sold with all parts even if price was higher as I wasted time ordering them and some will have a hard time finding the correct screws for the installation. Why can’t they just sell you a complete set? Had to use liquid pipe thread sealant as tape just leaked even after removing and retapping multiple times. I hope this review helps others only time will tell if this product will help with dirty water. Not sure how long it will last but will add a pressure gauge to it soon as didn’t find any locally.

Used this filter on my well water in my house. Very happy with this. The quality and value is great

I have been using this product for 9 years now and have fought with it every time I have to change the filter. We are on a well and this does a good job keeping the sand and silt out of our water. I have to change the filter every three months, and I dread it each and every time. The issue comes when putting in the new filter and tightening it. Hand tightening it doesn't work because as soon as the water is turned on, it starts leaking from the top. Now I have to turn off the water, unscrew the housing and try to keep it from dropping on the floor because the filter is now saturated with water and the housing is full of water too. Pull the filter, drain the housing, clean the o-ring again and try once more. Put it all back together and screw in the housing, but now it's much heavier because of the water-saturated filter. After a couple of tries, the threads finally engage, and it screws together. Give it a couple of tugs with the flimsy wrench, turn the water on...it leaks again. Do it all over again, and again. Finally, it seals and sits there for three months before I have to do it all over again. In 9 years, I have only had it not leak water on the first try only one time. Must have been my lucky day. This one is going in the trash as soon as I can find a system with NPT threads and doesn't require a screw-on filter housing. Wish me luck,
