I have talked with the city who owns my buildings about installing the anodes in our hot water heaters to get them to last longer, but they always shoot it down since it brings
up the cost big time.
As for garbage disposals, I hate the damn things. My apt units have 3 floors and the kitchen
sinks are back to back on a shared drain line for the disposal,dishwasher and sinks. Many
of my seniors never worry about taking any trash, they put everything they can down the
disposal. Had one last week, she had never used a disposal before she says, dumped a can
of spoiled sour kraut down the disposal and wondered why it would keep backing up. That was
a 3 hour job taking apart all the pipes under the sink and dumping all the kraut out into
buckets. then flushing out the disposal.
Have been replacing disposals like crazy to, cheap older ones have been falling apart with
the grinding plate rusting away. Sure wish I could just add another drain line instead.
Then down my garage, my kitchen drain lines combine to have 6 sinks on one line that drop
into horizontal runs before dropping down below the floor. Always have a plumber lined
up to jet out the plugged up drain lines when I get a call about water coming up in the
1st floor sinks. Talk about a messy job when they jet them out. Amazing that water would
even drain through some of them they are so clogged up with trash.And stink to.
