I assume you should do a backwash prior to taking it apart?
Oh, yes, most certainly. I've always done mine and it wasn't as easy as "normal" as it is under the deck so I have to remove it and drag it down the hill and from under deck to get the top off. I just replaced the exact filter you have. Removing the clamp is extremely easy. Just be sure you have released all pressure if there is any which there probably won't be if system is all shut down. Make sure no one is around to turn system back on and that, if on timer, it is disengaged or off. Might even want to shut the breaker off.
Extremely important..... After you have rinsed the grids off
first soak the grids in a solution of
powdered dishwasher detergent. Then do an acid soak after rinsing the detergent off well. I forget how long to do each soak, minimum time, as I just do each soak overnight. You can get a cheap plastic trash barrel, not the largest, at Wally World for the soaking.
It, also, helps to take a picture of each step of disassembling. Makes reassembly easier.
Inspect all parts, including big rubber gasket for top, o-ring (only a couple, or maybe one, that are in slots on the pipe where the manifold slips over the pipe inside) manifold, especially the little filter screen, and nibs that hold the grids in proper place and grids. Inspect for holes and tears of fabric and then wiggle them around to check integrity of the plastic ribs. Over time the plastic ribs will start to get brittle and lead to filter inefficiency and/or tear the grid fabric. BTW.... the grids are much cheaper purchased as a full set, on line. If you don't need to replace all then you have spares when you need them.
Putting the top back on, securing the big gasket, and tightening the clamp is a snap. The ss housing makes it much nicer to do as you don't don't get fiberglass particles embedded in your skin while hugging it.
Oh, yes. The screw in pressure gauge, on top, is very cheap if you want to replace it. I think you can find them for around $10 for the non-fancy ones.
When you open up all the valves in system, and turn on the pump be sure to stand back from the filter while it is building up pressure, just in case. The worst I've ever had is a bit of water leaking when I didn't get the gasket tucked in properly.
Check the integrity of ss vessel too. Mine, the one I'm replacing, is almost 30 years old and looks almost new inside. There were a couple of rust spots but were easily removed with a scrubby.
I'm sure there will be more suggestions coming. I'm a "super girl scout" and pretty mechanically inclined but I don't think it requires that. Every time I do it I still have to play a little with the placement of grids. Just expect that and don't get frustrated. I didn't have anyone show me how to do it 23 years ago and did just fine.
