Microphor toilet and variable speed pump

[Curt Sprenger]

Pete,

Thank you for the posting. Do you have the air operated Microphor toilet
in you coach?

Interesting...I was under the bed and found the water line strainer to
be cracked on the top, and dripping only a slight trace of water on the
floor. I change out the strainer and now the original water pump works a
lot better. I'm assuming the cracked strainer was sucking air. Can't
wait to install the variable speed ShurFlo water pump.
