I thought I read somewhere that the shower drain needs to be open, but can't find a previous post. I asked the RV place in TX, but they couldn't help.
Also, the previous owner gave me a green hose. I know the white one is for fresh water, but what is the green hose for?
What do I use to empty the grey tank?
Do I need to turn the water faucet on for a few minutes before lighting the furnance/hot water tank? Is there a seperate pilot light for furnace/hot water tank?
Keep the shower drain open all the time except when you are travelling with grey water: it prevents it from surging forward and up into the shower floor. Not a big deal if you forget; I've never had anything overflow the bathroom door. Valve should be open when dumping - acts like a vent pipe.
I use a green hose for water filling - couldn't find a white one in 100' length, which I often need. I sanitize the fresh tank periodically and don't rely on it for drinking water: bottled water in the fridge
I empty grey tank anywhere, but be discreet. Don't want to give the impression that you're dumping something irresponsibly. It's best to empty it where your landscape can best use it - let the plants have it rather than a storm drain. Tank empties best if trailer is slightly nose up, slightly tilted to the driver's side. The only time my grey tank goes into a sewer is when I am dumping the black tank; about once a week.
My water heater lights
automatically, but I get the best performance if, after filling the fresh tank, I hook up the hose to the city water connection, THEN turn off the hose and unhook.
Then I'm sure the water heater is full and there is water in the lines.
Make sure water is coming out of the hose before you hook up the city connection, otherwise you will be pumping air from the hose into your water lines. When that air comes through your taps it's like throwing water balloons around inside!
If you need to run a faucet to get the lines full, it should take a few seconds, not a few minutes.
Hope this helps! Happy Trails!
