Pentair Pentek 166219 Big Clear 10-Inch Whole House Water Filter Housing - 1" NPT Heavy Duty with Pressure Relief Button (Blue/Clear) - Perfect for Home Water Filtration Systems & Well Water Treatment

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!
