Some people have replaced them with Danco #17 O-ring pn 96734 from Home Depot to avoid forcing them.
Cool thanx for the tip. Im going to read reviews on the cfs500 and the sunsun 304 tomorrow. I read a bit tonight that has me wanting to look into it more before I order. Im also gonna call petsmart to see if they have any of the Rena's around. I will keep you guys posted and def review whichever I decide to go with. Even if the cfs500 only lasts a year, at $60, that's only $5 a month (less than I used to pay for world of warcraft lol). I just don't want to come home one day to ruined carpet.
