Back to checking
I stopped aboard today to check on things at the boat before we leave for a trip out of the country. When I was below I noticed there was urine in the bowl of the head.
I personally cleaned the entire head including the floor and bowl and flushed with fresh water when we last used the boat the other day. I then set the dial to "dry" like I always do.
Our marina provides free pump out service at our slip which they did on Tuesday.
Either the suction from the waste pump system caused waste water to back up into the bowl from the holding tank or....?
Our head is a brand new Raritan PHii.
Now I want to get a camera to see who's been on board when we are not there. Only the office has a key.
Changing locks may be cheaper than buying an IP or game camera.
