When we purchased Little Blue, the Technician went over everything about him AND I learned a neat new tech tip which I will share with you...in a minute...
In case you haven't figured it out, I am speaking of the loo, water closet, crapper, potty, toilet...whatever you want to call it. It works a bit differently in a camper, whether large or small--they are all similar in a camper. Many campers don't realize this little fact--and live to regret it--in a BIG way!!!!!
First, when you connect the sewage (black water) to the sewer line in the park, be sure it is tight. If it isn't, be prepared to jump!!!! AND LEAVE THE GATE CLOSED ON THE CAMPER!!!! Unlike your house, the camper has a holding tank. DO NOT just open the gate and let the sewer drain as it would in a house.
This will cause the liquids to run out and leave the solids behind to build up and dry out like a huge pile of stinky cement which will cost you a LOT of money to have removed!!!
So, leave the gate closed.
This is my control panel. You can see that I am about 60% full at this time (3 of the 5 lights are lit). When it gets to 5, I will empty the tank.
I have found that when my tank is getting full, it will begin to kind of bubble when flushed. I know then that I need to empty the critter.
So, we are now ready for the cool tip that I got from the technician at Loveall's when I got Little Blue.
