After reading the reviews I ordered this filter anyway, knowing it might not work right out of the box. And it's not. The device is not equipped with threaded corner adapters with quick release buttons attached. So you can't just plug and play and change the filter quickly. Don't worry, I opened up the parts box (that came with the original unit) with canister keys, scraps of pipe, etc., and here they are. , the parts I needed, and even a small roll of teflon tape. I fitted these parts to the block I replaced, put everything back in place, there was a small leak that required another twist to tighten and I was good to go. If you haven't saved these parts you'll have to scroll through some of the other reviews to see which one links to the knees you need. Much luck.
