When you are hooked up to power and sewer line

[red7654]

Hi I have a couple questions about when you are hooked up to power into a sewer line for an extended period!
1. When hooked up to power do you run your refrigerator on AC or on propane?
2. When hooked up to a sewer line I have seen videos saying that you shouldn't have your gray tank and black tank open to the sewer line. Is this correct?

1. A/C
2. Closed, open only to drain.

120 volt for the fridge .

Black and grey closed till draining required .
And ! after draining the black and closing the valve , flush three full bowls of water into the black tank ; to keep " stuff " from sticking to the bottom of the tank.
Dump black first , then grey , using the grey water to rinse the sewer hose .

Grey valve closed , or the entire park sewer system can vent through your gray tank and RV roof vents.
Some will say to , have a drop in your sewer hose to form a " P trap " , not allowed in most parks , and gives a spill potential , should someone or thing trip on the hose.

Fridge on AC, electric is free in most campgrounds.

Gray open, black closed, now that I have a macerator pump.

Either method will work.

1. We usually run our refrig on elec but have used propane for long stays also.
2. As full timers, we leave both gray and black tank valves open and have done so for 8+ years now, and it works for us and many others. So again both methods will work. For a side note, we do limit the amount of toilet paper that gets flushed down into the toilet. It's not a issue for us and it beats dumping the valves on a regular basis. So you have a choice, either put the TP into a waste basket or dump your valves regularly.

We leave our MH connected to AC power when we are at home. We don't leave the fridge on, just firing it up the day before we are to leave on a trip.

When we're at a CG connected to sewer we leave the black tank valve off until it is at least 3/4 full. We leave the gray tank valve open until the night before we plan to dump the black tank. That way, we have enough gray water to flush the sewer hose. I do leave a "trap" in the sewer hose to prevent anything from the sewer system from getting into the tank!

Yes, if you choose the closed tank valve method (most popular), you will need to dump the tanks or open your waste valves on a regular basis, usually every 4-6 days.
Note - I should have said "opening the valves to dump the tanks", in post# 6.

Usually the frig is set to Auto. So it will switch to shore power when present and propane as we depart. As for teh sewer it depends how long we'll be staying. Frequently we are only passing through. SO I hook up the hose and open the valves just prior to departure. If we are staying for a few days or longer I will leave the black valve closed and gray open so we can use all the water we want. Then the night prior to departure I'll close the gray valve to build up enough to flush the hose.

In most cases that is a good plan.

Depending on if there is an inverter and how it is wired it may not "auto" switch over to LP.

I use to run my last RV on auto. In the new RV my fridge is powered by my inverter so I have to remember to manually switch when not on a shoreline. I will typically stay on LP unless we are going to be on shoreline for at least 48hrs.

Full hookup site
Fridge/water heater on Electric

Dump valves closed
Waste tanks drain by gravity
Open valves allows liquids to trickle out as you use sinks/shower/flush toilet
Even look down the hole in a Outhouse/Pit toilet.....POOP mounded up and liquids flow away from the pile

Waiting until waste tanks are nearly full..then open dump valves
WHOOSH affect!

A high volume fast flowing river will move boulders
A small volume slow moving creek can barely move a pebble

Black tank with Poop/TP needs a WHOSH Affect
Grey tank with grease/oils/food debris/sloughed skin cells/soap scum etc not only can stink worst then Black but will benefit from the WHOSH Affect also

I prefer to put TP down the Toilet where the poop goes so I leave Black/Grey dump valve closed until full (takes about a week) then WHOOSH ....down and out---done

I hookup sewer line...dump...rinse///stow sewer line
Don't want it laying out there all week/2 weeks long. Birds pecking holes in it, CG Staff poking holes using weed whackers, fellow campers next door having to see it laying out there/tripping over it.

Personal preference.......ro each their own
