(Ericson 27) is piped directly to the top of the holding tank
, without a "loop". With a half-full holding tank
on a port tack, the liquid is near the top of the toilet. There's also a chronic smell that we can diminish by cleaning
but never eliminate. I'm thinking of putting in a vented loop to prevent backflow, but am concerned about the amount of flush water
needed to clear out the upward leg of the loop. (Thus the holding tank would fill up sooner). Are MOST heads plumbed with a vented loop and we've been putting up with the smell unnecessarily? Is my concern of excess liquid in the holding tank valid?
Thanks in advance!
