How to Clean a Big Blue Bag Filter? The Best Way to Clean Your Big Blue Bag Filter Today!

Okay, guys, let’s talk about something I messed with recently – the big blue bag filter. You know, those chunky water filters. I’ve been meaning to give mine a good cleaning, so I finally got around to it the other day.

First, I turned off the water supply to the whole system. No one wants a surprise shower, right? Then, I grabbed a wrench and carefully unscrewed the filter housing. It’s that big blue thing. I dumped out the old, nasty water that was in there.

Next, I took out the old filter. It was pretty grimy. There’s an O-ring at the top of the housing. I removed it and wiped it clean with a cloth. You gotta make sure that thing is clean for a good seal.

  • Rinsed out the inside of the filter housing with water.
  • Hosed down the filter itself. I just sprayed it with a garden hose to get all the loose gunk off. It’s amazing how much stuff these things catch.
  • For the actual bag filter, I turned it inside out.
  • Then I soaked the bag in a bucket of water. I rubbed it gently to get the dirt out.

After that, I put the cleaned O-ring back in place. Then, I inserted the newly cleaned filter, all nice and fresh, back into the housing.

Finally, I screwed the housing back together, making sure it was nice and tight. Turned the water back on, and checked for leaks. All good! The water pressure was noticeably better. Seems like those big blue filters are supposed to last around 10 years, according to the manufacturer, Pentair. But you definitely want to clean them out regularly, maybe after every use, so they keep working right and that suction stays strong.

It wasn’t a super tough job, but it did take a bit of time. I should probably make a habit of doing this more often, to be honest. My water tastes way better now!
