re: #88...
Yes, I agree about screwed up plumbing, so,I watch what I put down my drain, and went from a non-functioning garbage disposal, to the hex key saving the day, and a replacement or just repair...
A family I knew had a stand-pipe for its Kenmore with a self-cleaning filter washer to drain into, with reportedly not one back-up or overflow, and if I'm not mistaken one house I grew up in had a stand pipe too...
The filters advise against using in drains that are direct pipes too...
I notice threads around the drain, and even cutting them away, still notice, so I'm trying after buying a couple packs of filters to discontinue their use--one is still unopened while the other has one missng and discarded after its use being completely loaded with lint...
So me knowing what kinds of loads produce excessive lint--my daughter's guinea pig linen, will just only place the filters on my drainhose when washing them--as she's gone from completely doing the task herself to making me add on to my busy, daily schedule...
