Jim,

Great Post! I never realized that it was necessary to lubricate or drain a water filter on these toilets. I haven't done anything to mine since 2005 when I bought the coach. I had Newell service them back then, so I guess it's time to have them serviced again.

I may try to do it myself. I just read thru the pdf manual download and it is explained very well. It's nice to know that help is just a phone call away.

Thanks!
