Need a pentek big blue 10 filter replacement? Heres how to choose the right one for your needs!

Okay, so I recently had to change out the filter in my Pentek Big Blue 10-inch system, and I thought I’d just jot down my process, you know, for anyone else who might be facing the same thing. It’s not rocket science, but there are a few things I did that might be helpful.

First off, I made sure to turn off the water supply. Don’t want any surprise showers, right? I usually just follow the pipes and there is a main valve you can easily twist. Then I needed to relieve the pressure in the system. My setup has a little red button on top of the filter housing that I push in, and that does the trick. Then I heard some water start to trickle out. That is how I know the pressure is gone.

Next up, getting the old filter housing off. Pentek provides this big plastic wrench thingy, and it fits around the housing. A bit of a counter-clockwise turn, and the housing started to loosen up. Sometimes it’s a bit stubborn, but some elbow grease always does it for me. Be prepared, ’cause once it’s off, there’s usually some water still in there.

• Turn off water.
• Relieve pressure.
• Unscrew housing.

With the housing off, I pulled out the old, gunked-up filter. Mine was a Pentek brand, made of polypropylene (PP), I guess. It had done its job, that’s for sure. I just tossed it in the trash. And I chose to use the Pentair Pentek RFC-BB Big Blue Carbon Sediment this time.

Now, before popping in the new filter, I usually give the inside of the housing a quick rinse. Just to make sure there’s no leftover debris from the old one. It doesn’t have to be a deep clean, just a good once-over.

Putting in the new filter is easy. It just slides right into the housing. I made sure it was centered and sitting snugly. Then, it was time to screw the housing back on. I hand-tightened it first, then gave it a final turn with the plastic wrench, just to make sure it was secure. No leaks, please!

Finally, I slowly turned the water supply back on, watching for any leaks around the housing. Sometimes I have to tighten it a bit more, but this time it was all good. I let the water run for a few minutes, just to flush out any air or loose bits from the new filter. And there you go, clean water again! Oh, I also found Serv-A-Pure had good deals on these filters, in case anyone’s looking.

Easy Peasy, Right?

So, that is basically it. Changing the filter in my Pentek Big Blue system is something I do every few months. It’s pretty straightforward once you’ve done it a couple of times. Hope this little rundown helps someone out there!
