I'm looking at a leaking part from the fridge that came with my house a Samsung RH25H5611SR/AA. The part that's broke is DA81-05886A a $140 part, but only the upper tank is bad.
The upper cylinder (not the filter mount) is leaking. What does that even do? It looks like it's some kind of reservoir bottle that's dried out and cracked. Can this be bypassed? I just want to understand the function of it. My fridge has filtered water provided by an external reverse osmosis unit, so I think I can just bypass this in-fridge filter, but I'm not sure about this piece that I presume is a reservoir. You can see someone fixing it in this video.
I broke off the filter housing by cutting the water lines on the back you can see the cracked tank here,
The piece in question has writing on it that says,
CASE-WATER TANK DA61-05571A >PP< CAVITY NO #3 MICROFILTER CO. LTD
Still not sure why my fridge needs this piece or what happens if I simply bypass it.
