home rv dump - encantotom - 08-15-2014
hi guys,
my new shop will have its own 1000 gallon septic tank. the sewer main coming out of the shop is 3" that will go to the septic. i am putting a separate line to the tank that is for the rv pad that will be next to the shop.
a couple of questions for you.
1. are the in ground sewer connections at rv parks 3" or 4"?
2. is there any need for a separate vent for the rv dump to allow the waste to flow? i know when i stayed at steve B's he just has a regular cleanout for the sewer on his rv pad next to his house.
the connection will be only about 20' from the septic tank.

"a separate line to the tank that is for the rv pad"
What? Singular line/pad? I don't like the sound of that...no Sir!
I was thinking a minimum of 3...with a 1,000 gal septic Lol
Depends on Septic setup if you need vent...ask your septic installer...

Tom, The pipe can be either 3" or 4". I have seen both. The hose on our coaches is 3". The holding tank vent should be enough to allow plenty of flow. A vent has to be before the flow not afterwards.

Tom I've ran into 3, 3.5 and 4" pipes and some stab in's I have an adapter that fits whatever. Twin Fountains use 4" ..
I think the sewer vents thru the coach vent when dumping... I do remember staying at a park that had septic tanks and they had tall vents spread around.. when someone dumped we all got to enjoy it.....

The sewer hose on the coach is 3" isn't it

hose is 3", some rv parks have 3" others have 4".
For the vent I would think your septic tank should have a vent so when the 150 gallons of waste hits it the air has somewhere to go. Your coach tank has a vent so it can suck in fresh air as the waste is dumping.

Mine has a 4" pipe to the septic tank with no special venting. No problems in 18 years.

Three inch is better

there is enough width in the spot where the rv pad is going to be for a second coach i think. and can always T off of the septic rv drain. wont really know till things get put in for the septic tank. i will ask the septic tank guy about the need for a separate vent. if the rv dump can go into the septic tank separately, then the venting from the shop will probably provide a place for air to escape. i looked online and it does appear that most septic tanks have 2-3 spots to connect piping into on the entrance side of the tank.

At my house in AZ I had a vent at the end of my leach field... Way away from the house..
