KEEPING SEWER HOSE OFF THE GROUND

The bottom line is if park rules require raised hoses, either do it or don't stay there. The reason why it needs to be elevated is irrelevant...

A park requires it because it is a state law. The question is why is it a state law, not to dis-obey it but just knowing for what reason.

OK, so nobody likes to have leaks in their dump hoses.
BUT, which RV supply places sell replacement O-rings(gasket) for all the dump hose fittings? They wear out,.....develop tiny cracks in them. Apparently, they are of low quality.

BTW I go along with the rule about elevated dump hoses.

Camco 39834 Sewer Hose Replacement Gasket - Pack of 4

I've also seen them at times in the RV section at Walmart.

IF you get you hose off the ground, and have a "fall" from the trailer to the in ground sewer connection. The hose will completely drain, and will have nothing in it. With it laying on the ground. The waste has to suddenly go UP hill to the hole. The sharp angle can and will stop solids from running out. Plus it will always have something resting in it.

Its like your sewer pipe in your house. It has a "fall" from your house to the sewer connection. So that everything will run downhill. Cause stuff don't run uphill.

Good reply/response - Plumbing 101. (Payday on Friday is 102).

Slinky in rain gutter, rain gutter supported by blocks of wood, or?
(everybody carries wood blocks for "whatever", don't they?).

The sky is *not* falling (it's off the ground also), so -
"OTG" = No big deal...;)

How do those sewer gasses get past the P-trap?

It won't but it may go up into your grey tank, which I do not see as a problem either, since it is then vented out the vent pipe, but some people seem to think this is an issue for some reason :h

Sewer flies setting up home in your grey tank.

Help me out here... couldn't those same flies get in through the vent stack? This seems like another one of those things that there isn't really a great answer for...

Everyone sure does things differently. I find it interesting that some drag out and hook up the hose each time they dump rather than leaving it set up for the duration of the trip. I set it up and leave the grey tank open until the last night, nothing worse then the tub filling up before your shower is over. To each his own as long as this does not turn into the people who stick their water hose into the sewer hose to rinse it.

Be careful when doing this as you are making your gray tank a vent for the sewer system. Sewer gasses backing up in your tanks is probably not a good idea.

Both the black and gray tanks have vent stacks through the roof just like a house. Any gasses will vent there not into your RV.

Then if Air Admittance Valve doesn't fully close they can be inside RV.
If sink 'p' trap goes dry...inside RV

There are 'things' living in those sewer lines.

You are saying the reason some people are afraid to leave their grey valve open is because of a possible air valve malfunction. Your P trap reason will not happen when an RV is in use and the grey valve is open, which is what we are talking about.

BTW: Sewer flies go for the black and breed where "stuff" is accumulating on the wall of the tank. I have read of black tank infestations when people leave the BLACK valve open, not the GREY.

When the gate valve is left open on the grey there is no vacuum created when the water goes down the pipe (no whoosh) so no need for the Air Valve to function or malfunction.

I understand your need for the whoosh and that is why I and others close the grey valve for a day or so prior to using it to wash out the hose after a black whoosh.

Per Oregon law all sewer connections must be air tight and the hose must maintain a positive downward ... All county and state laws will be strictly enforced.

Does anyone have a link to the state regulations? I have to wonder if some RV parks have either misinterpreted the rules or have made up their own. Maybe they require hazmat gear when handling your sewer stuff?? (Being sarcastic.) I tried googling but couldn't find anything except for a mobile home park. What do they want you to do at a dump station? Have never heard of any such regs. when camping in Oregon.

I always just lay our hose on the ground and walk the contents along when dumping, and when ready to head home, just connect the ends of hose lengths together and keep them in the back of the truck. Setting up something to maintain a slope is too time consuming, esp. if just there for a 2-3 day weekend which is when I normally get the sewer stuff out only when ready to dump. If a park had an issue with a hose directly on the ground, then I would just dump and put the hose away after.

We've been at a few CG sites where it's been impossible to get a slope due to the height and location of the CG's sewer connection.

We were at one CG in Wa. where we used the dump station and their sewer system backed up and dumped most of the contents of our black tank all over the ground and onto the grass. Maintenance guy came along and said "it happens once in a while" like it was no big deal and just proceeded to clean it up right then and there with the hose. Maybe some CGs or their managers sewage effluent overreact and think everyone will die if even a tiny drop got onto the ground...?

That is what some folks have concerns over.
Personally I don't but then I don't leave any waste tank drain valve open unless dumping.

I like a FULL tank for that 'whoosh' affect :B
